Subject:Let's play guess the lens
Time:12:37 am
This is mostly for my photography geek friends, but anyone can play.

As a result of a discussion on Flickr, I pulled out my old Rebel XT and staged a set of tests today with three different lenses: the 50mm f/1.8, the kit lens, and the 17-40 f/4L.

Here are three 100% crops, all shot at f/8 in aperture priority mode. The shots are all at slightly different focal lengths, and the camera was moved slightly between setups, so you can't use the relative size of the images as a clue.

Can you tell which glass is which?

I believe you've been an evil test preparer and put them in just that order. I'm most confident in the top left being the fifty. Not that it really matters.

It would be nice if the exposure was close, but whatever...

I'll say the upper left is the kit lens, the upper right is the 17-40 and the lower left is the nifty fifty.
