thanks  http://www.markcrossphotography.com - A camera, glass, and some light.
I have this lens
It does a great job, what I like about it is the F2.8 and also the macro ability. It is attached to my S2 all time and is great for events 
I was expressing interest in getting one of these lenses and our generous Patron was kind enough to lend me his for a few days. I thought I'd do a few tests on it. As I was a bit short of a handy brick wall, this timber post was my subject. No PP at all just cropped and sized:
At f2.8 100% crop: 
At f4: 
At f5.6: 
At f8:

If I'm alone in a forest and my wife is not around to hear what I say, am I still wrong ??
thanks for that.... very sharp indeed!
cheers http://www.markcrossphotography.com - A camera, glass, and some light.
As said, at f2.8, sharpness is more than useable, at f.4 it sings!
I had the Tamron 28-75 on my D2x for the two days shooting at RAAF Williamtown (Fri) and Boat Harbour same as Fisherman Bay last weekend. The main reason, I didn't use my Nikon 28-70/ f.8 due to its size. IMHO, the photo qualities from this Tamron lens are the same or equal with the Nikon 28-70 f2.8, lack of AF-S on the Tamron but it's still fast in focussing, its price is 1/3 or close to 1/2 the price of the Nikon 28-70.

FYI. This is the f2.8 crop with moderate sharpening (225 0.5 0). I would not worry about shooting with this lens at f2.8 as even a little sharpening brings it up to near the quality of the sweet spot ~f5.6-f8 :
