photozone.de lens comprasion, tokina 16-50 vs tamron 17-50

could we think the tokina as pentax 16-50 and compare its sharpness to
tamron?????
Tokina AF 16-50mm f/2.8 AT-X Pro DX (Nikon) - Lens Test Report / Review
Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] (Nikon) - Test Report / Review
if we could, i give up buying 16-50 and 16-45 is the keeper for me.
thanks

Lens Comparison

It looks as if the Tamron beat them all, including the 16-45. Am I reading the results wrong?

The reviews give you a good idea of how the lenses are but, I still like looking at real world shots over charts and graphs.

The Tamron is an incredible lens at any price point. If I did not already have the 16-45 and the 16-50, I would get the Tamron. The Pentax 16-50 is qualitatively on par with the Tamron in terms of center and near center resolution, but the Tamron corner resolution is superior. One of the reasons I sold my Canon 28-70 when using Canon was to purchase the Tamron 28-75 which I felt was superior, lighter and less expensive.

Tamron make some incredible lenses. The 90 mm Macro is probably one of the best out there. It like the 28-75 are classics.

Even though there is only a 1 mm difference between the Tamron and Pentax, that is significant for me. That is another reason for keeping the Pentax's.

yes ben, 1 mm is significant for me, too.
i give importance of sharpness, bokeh and wide angle.
i have 16-45 which has 1 mm wider than 17-50 and better bokeh, but it is slower and less sharper. actually my only complaint about tamron is its bad bokeh.
ben, do you think 28-75 has better bokeh than 17-50???
thanks

Hello Halil;

In my opinion the Tamron 28-75 is one of the best lenses Tamron ever designed. As to the bokeh of the 17-50 Tamron, I don't agree that it isn't pleasant. That is a subjective opinion of course.

WOW!! That bokeh is very unfavorable indeed. It's about as smooth as sandpaper.

This is all I have for you atm bokeh-wise. Maybe later today the rain will lift and I can get some more photos.

I think, that 1x - 5x lenses are wide angle lenses and are designed for a large DOF shots (landscape...). For better bokeh, use 70mm and up focal length lenses.

When did so many people get the Tamron 17-50? I thought there were underexposure and focus problems?
