Tamron 28-75mm G2 - Bad copy?

[noneforit]

Hello

Let me preface this by saying I have no issue accepting this is my poor photography skills rather than a lens issue but here we go anyway.

Purchased a grey import brand new Tamron 28-75mm F2.8 G2 for my Sony A7iii, previously I had a 35mm Prime and 55mm Zeiss Prime.

However I am unhappy with virtually all the Tamron photos, they don’t seem sharp and just look very soft.

This was at 1/1000 and F2.8, I just looks out of focus and not sharp.

Most of the images look similar

I had no such issues with the previous primes.

Could it just be a bad copy?

Thanks

Sounds about right.... Budget zoom wide open Vs primes. What did you expect.....

How is it at f5.6? Have you looked at many reviews and compared your pictures to review examples.

It's not a budget zoom, but compared to the Zeiss 55 f1.8 my Sony 24-105 G has less detail.

Generally it's a very sharp superb lens.

This is my experience. I’ve had 3 copies. 2 on Sony and one on Nikon Z

I use the 28-75 G2 almost 80% of the time and find it reliable and sharp on a Sony A7iii. I also have a Sigma 35mm 1.4 art but this only gets out if the lighting is very poor. Of course there is a difference in sharpness / contrast but for how the photos are used (mainly screen) none of the clients have ever complained.

I would get another copy from WEX or such and see if there is any difference. WEX offer 30 day returns and I have used them to test the 24-105 and the lovely tamron 50-150 but seriously, the 28-75 was better than the sony 24-105 and much cheaper than the 50-150 without compromising quality so I've hung onto the 28-75 G2.
