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
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.
Nice to see you blogging again. I will have to look at this one more closely when I get some time.
Super excited to have you blogging again! A number of us homeschoolers have gained much from you to share with our kids and have missed your input. Great work, many thanks.
