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 was released 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 at the same time, so I decided to do this test, to identify how the latest version 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 one 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 instances 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 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. Photo was taken at 70mm focal length.

At the Tokina AT-X PRO 28-80mm f/2.8 AF 280 visible "onion rings" in the circles. While in 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 the strong side light. But at the same time, both a strong fear of 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 constructive are 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 a 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 a much better constructive. He is about 50-70 dollars more expensive first. So which lens one is more like it, you decide.





Tristan's picture
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.
