Tamron 28-75 2.8 really is a sharp lens

I recently acquired a beautiful FA* 28-70/f2.8 and no longer need my trusty Tamron 28-75 so I was listing it on eBay and used it to take some smaple shots for the listing.

It;s really tac sharp - it;s actually shaper than the FA* at the tele end, on the Tamron, resolution is already exellent from f3.5. While it takes up until f5.0 on the FA* to reach good resolution.

The FA* does have the Tammy beat at the wide end and the bokeh/ color rendition looks nicer to me.

I may end up keeping the Tammy afterall.

Sample shots below - I don't utually do measurebating, this was only done for the eBay listing.

I agree. It's a great people-shooting lens (short tele range on a crop sensor) and has constant f/2.8... and as you say just stopping down less than one full stop gives great sharpness.

Best wishes

I totally agree . . . .

I would never get rid of my lens - it's my go-to lens for shooting people after my DA* 50-135

Ditto here. It's also a fantastic portrait lens.

Yes! the Tamron is an amzing lens as I had done the same comparison and had posted in the other forum a few months ago. But, I also ended up selling the Tamron and kept the FA*.

I have the Tamron lens in the Canon mount, and I absolutely love it from f/4 and beyond for general use. It is even a slightly better FF lens than for APSc because of its greater general utility and good sharpness into the corners stopped down.

That said, color rendition and bokeh on the old Pentax a35-105 f/3.5 makes it easily my favorite lens for portrait work on a crop sensor. It simply is a great lens from 50 to 90 - even wide open.

First lens I bought. . .

I ordered one along with my DS and kit lens new. I've never sought the FA* replacement as the Tamron has always been a stellar performer. I think one thing that is often overlooked is the significantly smaller size -- the Aspherical lens design allows a 67mm filter which is 10mm smaller than the nearest direct FL/speed competitor, and actually makes the lens pocketable -- which raises its utility for me considerably.

I agree too. My copy is very sharp, I've got shots taken on a k20 at 75mm where resolution is almost down to a single pixel
