Wide (ish) macro continued: The EFS 24 mm STM

So yesterday I covered wide-ish macro with the 18-55 kit lens, so today I will go over a lens that I have found to be much more promising and fun: the EFS 34 mm STM. This is a lens that Gil Wizen turned me on to, and boy was he right. It is a great focal length, fairly fast (F 2.8), is VERY small (a so-called “pancake” lens) and is very inexpensive.

Closeups without tubes

Even without being used on tubes, it focuses quite closely, and is suitable for all manner of closeup photography. Here are a few examples of the lens being used without tubes:

This is a pretty straightforward (not too creative) use of the lens: a closeup of a small garter snake. The close focus allows an intimate look at the reptile and some of the background.

 

Alaus oculatus, shot in Ontario. One thing you will notice is the rainbow-like flare, I am not sure if this is common to all copies, or if it just because my rear element has a small crack in it. Whatever it is, I like it.

In this shot of Prionyx, you can see the flare crop up again.

A damselfly at dawn.

Enoplognatha ovata,with killed Ammophila. In this shot, the foreground details show good focus and contrast, and the sunstar is 7-sided and diffuse, which I find infinitely more attractive than the hexagon of the 18-55.

Closeups with tubes

A ways past dawn, the flare from the sun has less colour, but is still kind of awesome.

How to make it work

So I hope the above examples have convinced you that the 24 mm is a great lens for some closeups that are relatively wide compared to a standard macro lens. If you do decide to embark on trying this or the 18-55 or similar lenses, you will run in to the problem of lighting your subject…You could try a handheld flash, but I found this a bit difficult to use due to the proximity of the subject and the need for a steady base down low. What I ended up doing is modifying the Monster Macro Rig to mount the camera body to the rail, and using the magic arms on the rig to position the diffused flashes. This is a bit cumbersome, but I found that it works quite well. I have not done a lot of real environmental shots with this rig however, mostly incorporating wider views of the sky and trees rather than the nitty gritty of the vegetation. If I do manage some of these tougher shots, it could be that the Monster Rig is just too cumbersome to maneuver in close quarters.

Cheapskate Tuesday: (wideish) macro part 1, the 18-55 kit lens

When I have not been blogging for a while, I usually start posts off with a bit of self-flagellation, followed by apologies and a promise to do better in the future. But to heck with that, what about a bit of shameless self-promotion instead? Nah, that does not work either.

But something wakens Ibycter from her mighty slumber, and that is as shameful desire to take part in Science Borealis’ People’s Choice Award:

Now, for the self-flagellation: By no means can I hope to be the people’s choice in this, or anything, as my blogging has been abysmal the  past year. But I have been doing regular sci comm activities on Twitter where the majority of our current fieldwork on black widow spiders has been communicated. Of course, I have been throwing in a bunch of photography and the like, and often post images taken during my early morning sojourns to the fieldsite and beyond.

This season, I have been wanting to explore in more depth the possibilities of wide angle macro with an SLR. Last year, I was attempting to do so with the venerable A720IS, but I was getting really tired of having to trigger flashes via slave mode (it does NOT work well in the sunlight!).

So what wide lenses do I have? Well, the widest has got to be the old 18-55 kit lens, and often-derided, but actually quite nice little stabilized zoom lens, sold with many Canon kits (other manufacturers often have one too). My copy is a little on the old side, and the autofocus no longer works, but it should serve well for playing with.

So I slapped together a hideous contraption, added 12 mm extension tubes, and took it out a few times this season. I will show results in the wide, wideish, and definitely not wide focal lengths to give you an idea what I was able to achieve.

Definitely Not Wide

The 18-55 on 12 mm extension tube, zoomed fully to 55 mm. At this focal length, the lens serves well as a moderate focal length macro lens, with decent colour rendition and acceptable sharpness. This is an image of what I believe is Megachile perihirta.

 

Here again at 55 mm, the lens shows good characteristics for macfophotography. The downside is the hexagonal rendition of out of focus highlights (in this case the sun)…Even stopping down to f22 will not round out these edges significantly. My advice is avoid such situations when shooting with this lens.

This image of Scleropogon bradleyi (a big late summer robber fly) is also shot at 55 mm. Pretty decent sharpness, not too bad with colour rendition and contrast.

Wideish

This image of a western red-backed salamander I shot at 25mm. It is wide-ish bringing in a bit of the background.

This image of Prionyx canadensis (a sphecid wasp) was shot at 27 mm. It brings in a decent amount of background, showing that this was shot by the water at dawn. Note the hexagonal highlight below the wasp’s head. This is a harbinger of bad things to come…

Another shot of the Megachile male, showing it in front of Albert Head Lagoon. This was shot at 25 mm, and I was quite impressed with the contrast.

A group of Ammophila resting on Puget Sound Gumweed. This I shot at 28 mm, and I do like it…

Wide

This is a shot at 18 mm, as wide as it goes. Yikes! Look at all that crap! This focal length is very close with a 12 mm tube, and the point of focus is very near the front element. This means that crud in, on, under and around the front element is fairly well in focus. Being a zoom, the interior of the lens is definitely not pristine. This problem is exacerbated by the need to pump light close to the lens, resulting in ugly flaring of the crud as the front element is obliquely illuminated. I ended up removing the front element for a good cleaning, but the problem has not entirely disappeared. It is more manageable though.

 

Here is a shot with less sky, again at 18 mm. This shows nicely how the background is not fully blurred, and the scattered logs and moss of the habitat are visible.

 

What would a post be without a Coelioxys? Here is one on Island View Beach, sleeping on grass. This too was shot at 18 mm, and brings a bunch of the background elements into semi-focus.

I will sum up in a future post, but for now, let me state that the 18-55 is an underrated lens. It is tricky to use at the widest setting, but at moderate and long focal lengths is a decent stand in for a macro lens. The hexagonal highlights are not very attractive, but given care as to the field of view and lighting, it is very usable for both short tele and wide-angle macro. I have not tried it with autofocus, as my lens will not do this anymore (maybe I will get the guts to rip its guts out one day and fix it), but at the distances you will have to light macro subjects at, autofocus would be more of a hindrance.

Tomorrow, I will cover another option for cheap wide (ish) angle macro, which I actually found to be much more enjoyable and higher quality than the 18-55. I will also cover briefly how I used both of these lenses.

Hexura picea feeding videos

 

Catherine and I just got back from a trip to the Walbran Valley, where we met up with an awesome tarantula relative Hexura picea. Read all about it here, and then check out these videos I took today of feeding specimens we brought back alive. They seem to have taken well to their new settings!

#TeamBlackWidow is back in the field!

This post will be an update on #TeamBlackWidow...As you may have guessed, based on following the #TeamBlackWidow hashtag on Twitter, we have arrived back in BC and are engaged in the early stages of our season’s fieldwork. Catherine and I are set up in a really nice basement suite in a house in the countryside (owned by arachnologists!) and are very much enjoying the new space (compared to our 400 square feet in Toronto).

We have been to our fieldsite several times for reconnaissance and mapping, and have staked out quite a few logs on the southern portion of the beach for observation.

The point prefaced with L2XX are new territory we have mapped out, and are largely not congruent with our 2016 observation sites

So what have we found so far? Well, the spider season this year is much delayed compared to what we saw last year, with no females with egg sacs, and most of the spiders just beginning to fatten up on springtime bees and flies.

Only this past week have we seen any adult males at all, with most males we have found being only penultimate (one molt away from maturity).

The males all have the typical “winter male” form, being larger than summer males, and quite dark, much like an immature female.

By way of comparison, we saw our first mature male and our first egg sac on April 20 of last year. This year, as of today, we have only seen two mature males, and not a single egg sac. The weather has been cool and often rainy, and the widows are off to a slow start.

With these conditions, we have not been focusing on field observations, instead working to prepare a set of experiments to perform before we have to return to Toronto in June.

Weekend Expedition 73: Mississauga woodlands with Gil

Yesterday I went out to the woodlands near University of Toronto Mississauga with Gil for a springtime walk. We were hoping to see some post-breeding Ambystoma salamanders, and whatever else caught our eye…After a long cold and largely photo-free winter, this outing proved to be rather awesome…

The first big spider we saw was this pretty amaurobiid.

Their velvety abdomens are quite lovely in soft light.

On one of the treetrunks we examined, we saw this gorgeous little male jumper.

What a stunning little spider! What could he be? He looks reminiscent of Habronattus

Turns out this is Naphrys pulex, indeed a Habronattus relative, and such a handsome fellow!

Gil found this anyphaenid (ghost spider) and as soon as I saw it, I knew Catherine would be very excited. We don’t have a ton of these in BC, but it seems Ontario has a few more.

What an elegant looking ghost spider!

We did find some Ambystoma, starting with this awesome Jefferson’s salamander

And a spotted salamander was a real treat to see in the wild!

Look at the pretty spots! So cool to see in a burrowing salamander.

I did find a lovely ant in the genus Aphaenogaster…This somewhat large red one should be easy to ID to species, but my book is at the ROM currently…

And the absolutely, most fabulous find of the day (in my opinion) was this absolutely stunning hibernating queen European Hornet…

We do not get these in BC, so I was hugely impressed by the large size and vivid colours of this monster of a queen!

I am sure this is one of the most lovely social wasps I have laid eyes on in North America….

The day was rounded out nicely with the find of a pair of Platycryptus undatus, larger eastern versions of the Platycryptus californicus we are used to from BC

Really impressive jumpers these P. undatus are, with gorgeous fuzzy faces!

Weekend Expedition 72: Leslie Spit with Gil and Catherine

20161023-img_4179

Fall is swiftly turning into winter here in southern Ontario, with cold nights and disappearing leaves…This weekend looked like the last in while to offer any kind of warmish temperatures, so Catherine, Gil Wizen and I headed to Tommy Thompson Park (Leslie Spit) o see if we could find some cool arthropods. The following is a condensed collection of pictures I managed to get.

20161023-img_3656

On the way to pick up Gil at the train station, I snapped this shot. It actually has Catherine in the frame.

20161023-img_4161

You can see that the goldenrod has largely gone to seed.

20161023-img_3705

A surprisingly colorful Phidippus audax.

20161023-img_3718

Just look at that abdomen!

 

20161023-img_3670

There were quite a few syrphids about, some of them just had to bask on exposed perches in order to warm up enough to fly.

20161023-img_3767

We saw about a jillion cucumber leaf beetles (Diabrotica undecimpunctata), mainly feeding on goldenrod

20161023-img_3747

A “buffalo treehopper” (a membracid in the genus Ceresa) hides out on a willow stem. Gil took a bunch of shots of this with both wide lens and MPE-65, so look out for them!

20161023-img_3721

This is an alydid bug (broad-headed bug), one of several we saw basking in the morning sun. This is likely Alydus eurinus, a common species in Ontario.

20161023-img_3855

These beachside wolf spiders (Pardosa) are plainly ornamented, but just a lovely shade of bluish gray.

20161023-img_3836

A really really big mite we found under some bark. This is likely a species of Trombidium.

20161023-img_4191

The subjects of a high-mag MPE-65 shot have got to be really calm creatures. Check out how this pierid is dwarfed by Gil’s diffuser.

20161023-img_4190

It was the most cooperative pierid ever.

 

20161023-img_4197

This is my attempt at wide-angle macro of the same insect.

img_3863b

A squashed Pardosa wolf spider on the road, being fed on by Myrmica rubra.

20161023-img_3874

Winter is definitely coming. This Culex pipiens has a “hypertrophied fat body” (she is fat) a condition that adapts her to living out the winter in a sheltered location.

20161023-img_4076

Golden dung flies (Scathophaga stercoraria) having an end-of-summer romance.

20161023-img_4002

A Myrmica rubra worker investigating a fungus-killed caterpillar. If she feeds on this carcass, and gets infected, her colony will likely kill her, then dispose of her body somewhere far away.

20161023-img_4113

The alianthus webworm moth (Atteva aurea) is a beautiful species that is not found in BC…Though seems quite common here.

20161023-img_3879

A gorgeous amaurobiid spider, recently disturbed from her cribellate silk retreat.

 

20161023-img_4141

A running crab spider in the genus Thanatus. They look much the same wherever you find them.

20161023-img_3899

OK, I saved one of my fave shots for last, this time it is an Agapostemon bee sitting in a flower. I just love the colour combinations and the textures.

A roundup of recent shots

IMG_4428

The spider fieldwork Catherine and I have been doing at Island View Beach progresses slowly. Natural history observations and experiments take up most of our nights, but I have still been getting the opportunity to do some photography and arthropod outings here and there. Here is a sampling of some recent shots that I think you might enjoy.

IMG_3281

This is Island View Beach, near our fieldwork site. It is a gorgeous beach, and a rare habitat type: dune vegetation is in short supply around here.

IMG_3287

One of the rare plants to be found on Island View Beach is the yellow sand verbena, a gorgeous dune plant with lovely-smelling flowers.

IMG_4486

This moth, the sand verbena moth (Copablepharon fuscum) depends on the yellow sand verbena, and is endangered. Catherine is working on a blog post about the controversy surrounding this species.

IMG_4710

On a recent outing to the beach in the daytime, I was very excited to find this robber fly, which I believe is Laphria franciscana. Wonderful blue eyes!

I have still had my eye out for spiders, and this Misumena vatia with a honeybee was a lovely find in Uplands Park.

I have been finding some bee flies lately resting on grasses. Here is one I shot with the A720IS.

Nighttime fieldwork on Cordova Spit allowed me to shoot this Ammophila against the darkening sky.

IMG_4862

The next morning, I found this purplish copper resting on a dead flower.

IMG_4897

I also found a beautiful potter wasp, an insect I do not often see resting on vegetation.

IMG_4453

During nightwork on the beach, I found this mother woodlouse with a load of babies.

IMG_4536

This sleeping aggregation of Coelioxys and Ammophila was particularly impressive. I wish I had been able to shoot hem at dawn!

IMG_5078

Early this morning at Mt. Tolmie, I found this beautiful little cuckoo wasp sleeping on some grass.

IMG_5107

A stinkbug against the dawn sky.

IMG_5138

This lovely cuckoo bee is either an Epeolus or Triepeolus…I found three of them at Mt. Tolmie this morning.

 

Coelioxys cluster

IMG_3073

Last night, Catherine and I were out again all night, performing what was ultimately a futile spider experiment on Cordova Spit (TIXEN in the SENĆOŦEN language). The one thing that did go right was that the dawn had some decent light, so I set out early to try to get some photos of sleeping hymenopterans.

I did not end up shooting very many, as I found this absolutely lovely cluster of Coelioxys which were just begging to be shot. These parasitic megachilids are wonderful subjects, and seem to sleep in small aggregations, sometimes with Ammophila wasps.  Their preferred perches are the dried seedheads of the Puget Sound Gumweed (Grindelia integrifolia), a fragrant seaside plant that is a good place to find halictids in the daytime.

Anyway, here are some of the pictures I took this morning!

IMG_3533

Shot with the 100 mm macro, this shot shows the mixed cloud of dawn, and the dew collected on the bees

The same bees shot with the A720IS, in the wideangle macro style.

A lone Ammophila shot with the 100 mm. These wasps are so elegant!

IMG_3097

A similar view of the Ammophila with the A720IS. With this wide a shot you can really see the extent of the sky

IMG_3110

I turned around with the A720 to show the vegetation of the spit to the north

IMG_3528

As usual, when I find a great subject, I try to frame some up in portrait orientation, just in case I get the call for a National Geographic cover!

 

Figuring out the A720….

CRW_2909

I am continuing to tinker with the Canon A720IS for wide angle macro, as it seems this will be the only machine I have for the purpose for he forseeable future….I now have a method of holding the camera and the slave flash, but would like to do some more tinkering before I lay it all out. Today I was up at Mt. Tolmie again, where I waited in vain for a glorious dawn…But I did see a spectacular moonset!

Click the image below for a larger version.

moonset pano

 

The subjects of my macro experiments were snakeflies and some Nomada cuckoo bees. These relatively inactive subjects proved ideal for my tinkering, and I managed a good many angles for each. If you have any thoughts on these compositions, please let me know….I was constrained a bit by ambient light, as it was near dawn, but in the future I want to let the landscape show through more.

CRW_2731

Snakefly on dead camas. I kept the sky dark here, which is kind of a fashion cliche from a few years back, but I like the brooding atmosphere

CRW_2754

This is kind of full ventral, but the light is not “believable”…

CRW_2724

This is kind of cool, as the insect is descending…I do say that I “chose” these compositions, but with the shutter lag of the ancient compact, I get what I get!

CRW_2824

This shot of a Nomada is pretty straightforward. I kept the sky and tree dark to keep the brooding atmosphere.

CRW_2855

Here I have tried to get some background vegetation other than trees, but the grass actually resembles a tree!

CRW_2859

This is a peeekaboo shot of the cute face of the bee.

CRW_2877

The one shot I got that worked out of the cloud-obscured sun with the bee. I really like this one, even with the spittlebug below

CRW_2863

Another view of the Nomada while sleeping.

OK, now for some comparisons, here are some shots of the same subjects with the 100 mm macro on the DSLR

IMG_2894

Not as much interest in this background.

IMG_2964

What I like about the 100 is how I can maneuver everything precisely o get a clean composition…That being said, maybe it is a bit stale.

IMG_2990

This shows the stiffness of the sleeping bee’s posture

And in other news, check out this beautiful bee fly I found!

IMG_2955

The tip of the abdomen is orange at certain angles

And a bit wider to show more of the perch

 

 

 

Experimentation with sleeping bees and wasps

CRW_2600

This morning Catherine and I tried something different with our spider observations: instead of going out at night, we would get to the beach before dawn, to catch the tail end of spider activity. Turns out, as soon as any light is in the sky, the widows are out of sight, presumably to avoid dawn-foraging birds. So that meant I had a bit of time for some photography!

I really wanted to try out the small Canon A720IS I had used on the alligator lizards in the context of capturing wide angle closeups of sleeping bees at dawn. I did manage some shots of Ammophila wasps and Coelioxys bees, but I am not entirely sure I am pleased with them. Perhaps the strength of the camera lies in wide angle macro in better lighting conditions. Anyway, it made for some neat images, which I share below.

CRW_2568

Ammophila, all lit up by a surprisingly well-behaved slave flash, the beach habitat stretched out behind.

CRW_2617

An in-your-face view of Coelioxys, with a bit of colour in the sky.

CRW_2575

Coelioxys with a bit more of the trees toward the beach showing.

Now we move onto dawn shots of the same subjects shot with the DSLR and 100 mm macro. We also found some cuckoo wasps!
