tamron 70-200 f/2.8 dilemma

jimb · 11-16-2010, 02:24 AM

Folks,

I have a choice of selling Tamron 70-300 Di LD lens to get 70-200mm f2.8. My question for you is do you have any comparison of image quality in overlapping apertures and focal lengths.

The Tammy 70-200 is a very very good lens. Just get it, you won't regret it. I've had a Tammy very similar to your and there is just no comparison to the 70-200.

nice to hear. I went to my local camera shop. He had no stock but he said I wont see any difference in image quality in daylight and at same aperture. could you share any comparison pictures.

If you haven't seen this thread, this should be all you need to tell you there's no comparing the two.

thank you so much. But that does not compare. I see that most photos were shot with f4.5 and f5.6. That even my Tammy can do. So what is the difference.

Basically, the 70-200mm is far superior optically... there's just no comparison.

While I don't own either lens, I'll just comment that the camera store guy may be right. How do you intend to use this lens? If you are shooting outdoors in good light at f/8-f/11 you may notice no difference at all. In low light and wide open apertures you will likely notice the difference right off. I own the relatively cheap Sigma 70-300 which often gets compared to your Tamron and are considered around equal in quality and price. My f/11 shots, especially in the shorter ranges of the zoom, will hold their own against any tele-zoom. At apertures wider then f/8, it starts to become noticeably soft.

What are you planning to shoot with this lens? If indoor sports and flying birds are in your plans then the 70-200/2.8 is the ticket as you will get sharper images because you can shoot with lower ISO and the faster shutter speeds needed. I have seen some stunning pictures from this lens as jsherman's photos illustrate. This lens is much more versatile and can produce sharp images at all apertures.
