The AF Performance of the Lens is Very Good Both in Terms of Speed and Accuracy
The new Tokina AT-X 535 PRO DX
zoom lens is a 50-135 with a
fast constant aperture of
digital photographers the similar to the industry
telephoto zoom lens in
35mm camera terms but is much more
compact and lightweight.
The lens features SD glass lens elements to correct for
chromatic aberrations and focuses all colors accurately at the film plane,
making the AT-X 535 PRO DX an APO lens. The front element has a newly formulated
WP or "Water Proof" optical coating on the glass. This new coating makes marks
such as spots left by water or finger-prints much easier to clean than standard
Note! Not recommended for use with "full-frame" FX digital or 35mm film SLR cameras. AF not supported by D40 and D60 cameras.
Other features include a built-in tripod collar and
Dedicated to sophisticated design and engineering, Tokina makes lenses with an excellent reputation; the best of these bear the AT-X designation, denoting "Advanced Technology-Xtra." These models--bearing a gold stripe indicating premium grade optics--include the most advanced technology, superior mechanisms, and lens coatings.
Tokina's DX designation is on lenses designed to be mounted on
cropped sensor cameras, except that while they can be mounted on other EOS cameras, the projected image is too small to cover the whole sensor. Also, the Tokina lens is designed for the 1.5 crop factor (used by Nikon, Pentax and Sony)
and not the 1.6 crop factor used by Canon.
One Touch Focus Clutch Mechanism
A refinement of the focus clutch mechanism has been incorporated in
the AT-X 280 AF PRO Nikon and Canon mount, so that now the lens
focus ring can be snapped back to the manual focus position at any
time, from any position. This improvement means it is not necessary
to change the AF/MF switch (on the body with Nikon or the lens with
Canon) every time the lens is changed from auto focus to manual
WR - Water Repellent optical coating on the glass
water repellent coating
makes marks such as spots left by water or finger-prints much easier to
clean than standard multi-coating
Tokina 50-135 review, April 19, 2009
By Chris Draper (St. Louis)
This is my second Tokina lens, my first was the 12-24mm. Folks if your considering a "daily driver" type lens, this is a good one. I really considered a sigma which would give me up to 150mm and I already have a sigma tele-converter. But, if I want a Zoom, I have one.
I needed a lens for everyday use and this is a Great lens and not just because of the cost savings. The 50-135mm is sharp, very sharp, great detail and built to last.
If you're into name brand products, you know who you are, because you're reading this in Nike Shoes this lens may not be for you. If your not driven by branding, this is a must have for the Bag. 5 out of 5 stars.
Great Portrait Lense with Some Issues, October 27, 2008
By Michael Sibley "BearTracksMedia" (Texas)
I purchased this lense specifically for shooting portraits. For that use it's a wonderful lense. Very sharp and easy to focus. I really like the tripod mounting ring because it allows me to switch between portrait and landscape with just a flip of the lense without moving the camera.
One issue I have is that when I mount it on a tripod using my Nikon D300 my quick release base blocks access to the wired remote shutter release socket. The only other issue I have is with the butterfly lense hood. It cannot be rotated so the large leafs are at the top when in the portrait orientation. So when I shoot verticals I have very little lense protection from my top light (Hair Light). I replaced the supplied hood with a third party hood which works no matter which way the lense is oriented.
