Tokina 28-70mm f/2.8 AT-X AF vs AT-X PRO 28-80mm 1:2.8 280 AF. Compare Test




Tokina 28-70mm f/2.8 AT-X AF and Tokina AT-X PRO 28-80mm 1:2.8 280 AF is autofocus zoom lenses with maximal aperture f/ 2,8 and the most popular for everyday shooting focal length. Both models were derived from Angenieux AF 28-70/2.6. Tokina company bought the rights to manufacture Angenieux and in 1994 released the first version of the lens - Tokina 28-70mm f/2.8 AT-X AF, which is provided in this test. Then, after a series of modifications in 2000, an upgraded version of this lens - Tokina AT-X PRO 28-80 mm 1:2.8 280 AF. I had the opportunity to use these two lenses simultaneously, so I decided to do this test to identify how the latest version is better than the first. So start with the mechanics.

Handling and mechanics

Tokina 28-70mm f/2.8 AT-X AF vs AT-X PRO 28-80mm f/2.8 280 AF

As you can see from the photo Tokina 28-70mm f/2.8 AT-X AF has a smaller size and weight than the Tokina AT-X PRO 28-80 mm 1:2.8 280 AF. And it is perhaps the only advantage. In all, the rest of it is constructive loses the latest model.

Now compare Tokina zooms of optical performance.

Note: All tests are done on the lenses that were at hand; it does not select the best copies, but only single instances "as is." Therefore, tests are not absolute but only relative to this instance's lenses.    

Tokina 28-70mm f/2.8 AT-X AF vs AT-X PRO 28-80mm 1:2.8 280 AF. Sharpness test

All photos were taken at the aperture f/2,8 in manual focus mode with confirmation on the green point. For the purity of the experiment, the second model was used in the range of 28-70 mm only.

Bokeh Test

Bokeh is subjective stuff. Moreover, it may be different depending on the subjects. Here are a few examples of bokeh with different subjects. I took the photo at 70mm focal length.

At the Tokina AT-X PRO, 28-80mm f/2.8 AF 280 visible "onion rings" in the circles. While the first lens does not. Personally, I liked more bokeh Tokina 28-70mm f / 2.8 AT-X AF. I think it is more air; the picture is more artistic.

Both lenses have good contrast and well with strong side light. But at the same time, both strongly fear direct backlight, especially on the long end. It seemed to me, Tokina AT-X PRO 28-80mm 1:2.8 AF 280 copes better with backlight. Maybe an important role in this is constructive - front lens focal lengths under certain deep-seated in the barrel, which partially protects the lens from stray light. In the first version, such construction is not provided.

 

Conclusion

As shown by examples, both lenses have good optical performance. Yet, the model AT-X PRO 28-80mm 1:2.8 AF 280 has better sharpness and contrast. But the 28-70mm f/2.8 AT-X AF, in my opinion, has a more artistic image. Also, AT-X PRO 28-80mm has much better construction. He is about 50-70 dollars more expensive first. So which lens one is more like it, you decide.

Thanks for the article. I just wanted to point out a small correction; the Tokina 28-70mm f2.8 AT-X with a 72mm filter thread is not derived from the Angenieux design. It was the next two generations of that lens ATX- Pro I, and AT-X Pro II (both with 77mm filters) that was based on the French design and far superior optics. And the ones sold outside of Japan were labelled f2.6-2.8. I'd love to see this test again using one of those two lenses.

Hi all. Interesting read. I have both Tokina AT-X Pro's 28-70mm F2.6-2.8 and 28-80 2.8. Both use the Clutch MF/AF machanism. Both take a 77mm filter. The main difference are: the 28-70mm does not have a apature Ring settings (Minolta/Sony AF mount) and does not have a Focus-scale window. And of which is one is Sharper? I need to do some comparison test. Both are on APS-sized sensor Cameras: Sony alpha 350 (27-70) and Fuji x-m1 (28-80) 14mp and 16mp respectivley. Probably the 28-70mm is Sharper.

The Tokina AT-X 28-70mm f2.8 you are testing is not based on the Anginieux design. The next version with the 77mm filter thread, sold in the USA as AT-X 28-70 f2.6-2.8, and, AT-X 28-70 f2.8 PRO in Japan, and, the Pro II are based on the Angenieux design. Please correct your blog as you are promoting misinformation.

Thamks for comparison! All fast Tokina 28-70 versions lack contrast and sharpness close MFD wide open between 50 and 70 mm, but improve a lot at f/3.2-3.5 already. Much confusion still out there about different 28-70 versions. I owned and serviced them all, and guess what you find inside? ALL four versions with MFD 0.7 m (the above AT-X 2.8; AT-X 2.6~2.8 Pro I & Pro II; AT-X 2.8 Pro SV) share exactly the same famous Angenieux lens design! Sorry to end all rumours about that... Disbelievers: buy a set of screwdrivers and find out for yourself ;-) Differences: housing/build quality (72 -> 77mm thread & hood due to pseudo-IF), AF/MF-clutch, lens coating. The latter is best on the last version, the Pro SV. Highly regarded "foMag" test results (max. 10 pts opt./mech.) - for 35mm film, of course: Pro II: 9.0/9.2 (Feb. 1996) Pro SV: 9.2/9.4 (Okt. 2002) -> Pro SV compared to the Angenieux design:
