Hi,

I just purchased the Tamron 28-75 f2.8 to use on my D70s. This lens is known to be a sharp lens. I tried it out at a local camera store and decided to purchase it. I checked online and purchased it from Beach Camera. I received the lens today and took some photos of my daughter and all of them seem soft.

What steps do you take to make sure the lens you purchased is performing as expected?

Thanks

Angela

First of all,

What lighting conditions were available when you took the shots?

Taking them at 2.8 is not the ideal aperture for shooting people.

Shoot at different apertures before passing judgement onthis lens.

The 2.8 allows you more latitude in taking a shot in low light.

I have this lens and find it does as expected. It is a great lens.

Angela, what settings were you using? It would be nice to see the pictures. Personally, I like softer for protraits, and even have one of the shooting banks set for portrait. This was one of my favorite lenses on my KM 7D, and I ordered one along with my D200.

Oops, I guess I should have posted a couple of pics....

Here are links to 3 pics that have the exif data attached. I didn't want to shrink them b/c I want you to be able to see them at 100% with no editing. The pic with the yellow top was taken with my 85 mm and I was expecting the Tamron to perform close to this lens as far as sharpness. The lighting was pretty much the same for all 3 photos.

You used f2.8 on the two from the 28-75 and f4 with the 85. Try the same settings and also the same perspective (pose). There may well be a sharpness issue between the two lenses, but I don't see the ones from the 28-75 as being bad. Most 2.8 lenses do better at f4 and above.
