Today I had a bit of fun with my new macro lens, the Tokina 100 f2.8 AT-X Pro D. It feels good in your hands, sturdy and with a professional finish, I like the lens hood too, looks pretty cool when mounted, I left it on all the time.
The lens is a joy to use, the autofocus system is ok, a tad slow but I mostly shot in manual while doing the extreme close ups. As usual, wide open is quite difficult to find the right focusing spot, especially if you are a dork like me and don’t use the tripod, but his is truly not an issue, is normal.
As far as Photozone concerns, probably among the most qualified sources on the internet for camera lens reviews, the resolution is excellent from wide open up to f11, it is ok at f16 and goes down dramatically due to diffraction at very small apertures. Today I used it between f2.8 and f14, and the out of focus area you get at f2.8 is very nice, in fact I’m very much looking forward to use this lens for my next portrait session.
