When I first got access to the Tamron 15-30mm f/2.8 VC lens (which we recently reviewed), I got curious about other potential lens options already available with the similar focal length range, build and fast aperture of f/2.8. After a quick search through our lens database, I found the Tokina AT-X 16-28mm f/2.8 Pro FX. This little gem has been available for a while now and although I have heard a lot of good things about it, I never had a chance to actually try it out. After receiving the lens along with a few other lenses like the Tokina AT-X 11-16mm f/2.8 Pro DX-II (which I will be also reviewing very soon), I headed off to Death Valley National Park. Although I primarily used the lens with my infrared-converted Nikon D800E, which as I painfully found out later turned out to be a bad choice for IR as explained further down in the review, I was really curious to see how it would do, given its extremely attractive price of $629. At this price, I was expecting the Tokina 16-28mm f/2.8 to be a poor performer, because the price just did not seem to be right for such a fast zoom lens with a “pro” label on it. After using the lens and testing it out in my lab, I realized that I was wrong – it turned out to be a hidden gem.
One of the interesting announcements from last week was Tokina’s AT-X 70-200mm f/4 Pro FX VCM-S. Being the first Tokina lens to incorporate optical image stabilization, the 70-200mm f/4 Pro is a direct competitor to the excellent Nikkor 70-200mm f/4G VR lens. The Tokina 70-200mm f/4 seems to be similar to the Nikkor 70-200mm f/4G in a number of ways. Its optical design incorporates 19 elements in 14 groups, with 3 ultra-low dispersion lens elements (vs 20 elements in 14 groups and 3 ED elements) and the lens does not come with a tripod collar either (available to be purchased separately). It has the same filter thread size of 67mm and has a slightly shorter barrel. Unfortunately, at 980 grams, it is a 130 grams heavier than the Nikkor, which is a pretty noticeable difference.
Because the glass elements in a camera lens are round, lenses project a circular image onto a camera’s sensor plane. This projected image circle must be large enough to cover the rectangular sensor, like so:
