Thanks!
I couldn’t print the test page correctly today, so I don’t have nothing serious yet. However, on 10x magnification on live-view, at least on the center, the picture looked really sharp. I was surprised! Maybe I have a little front or back focusing issue, I don’t know.
Don’t just do all your tests from one distance either, do some from 5 meters, from 10m, and from 20m.
I don’t understand what you’re meaning. My lens is a 28-105, and at 20m, it will be hard to judge of the sharpness if only what I can see is a tiny paper sheet…
While you’re at it, compare the focal lengths. 18mm is a decent wide angle lens, but 28mm really isn’t very wide. You want to be sure that it’s wide enough for your intended purpose.
Personally, I found the 105mm on that lens very attractive. For me, I found 55mm too limiting. I don’t play in the wide-angle very often, so I hope that this will not be an issue.
You’ll also have to remember that your 7D has a much higher resolution sensor than the T3, so the results won’t really be exactly comparable
I wonder if it can be a good idea if I set my 7D on a tripod and test my two lens on similar focal lengths on the same body?
