Quick question. Somewhere–God only knows where, but I remember seeing something that tells you how to figure out what kind of macro you’ve got.
Well, I ain’t got one.
What I do have is my Darlot antique lens (80mm focal length and 40mm diameter; ignore crap photo, I was rushed.)
That, and with my Canon xTi and Tamron 75-300mm telephoto, zoomed to 300 and with the Darlot held up to it (I’ll need to rubberize the Darlot if I’m to toy with this), I got this (in millimeters):
(again, ignore crap photography, I just wanted to see if I could focus it and make it bigger than what I’d done with the 28-80 lens).
So, Canon sez the sensor is 22.2×14.8mm, and I seem to remember someone saying macro was sensor size divided by true image size? Would that be (approx) a 2.2 macro? Or maybe the inverse, a .4545… macro?
I forgets. We drinks ya know. But just asking. Not that I could catch a bug with it or anything–the depth of field is horrible.
p.s.; it took a long time (1/4000 exposure, 1600 iso, these little phuckers are phast…), but I got a couple ants. They’re about 2mm each (the backend of one in one pic is about 5mm–guestimations; they don’t sit still for measuring) Pics edited differently.
