Any thoughts on the 28-75 on K1?
From what I've read it is soft in the corners, even when stopping down to F8, has decent center sharpness, it has a noticable vignette, doesn't have the best control over harsh lighting conditions, and is kind of just ok.
From what I have experienced, it was fantastic on my apsc bodies though the 28mm wide end often wasn't wide enough, and I did manage to ruin some pictures with some ugly ghosting in direct sunlit pictures . On my K1, I really love the pictures that come out of it. I happen to like a slight vignette so I have no complaints there. The corners are a bit soft, but for what I do they are good enough. A lot of my shots are candid pics of my kids so they are usually closer to the center, and I like to have the background blurred so corners are soft anyway. Maybe some day I will save up for a the 24-70mm, but probably not unless I decide to become a wedding photographer. I would rather save up for some ltd primes.
Basically on FF you probably won't be using it as your go to landscape lens, but for people pictures where the subject is generally not in the corners, it does a good job. And for the price, well, personally I would rather have a good enough zoom, and some great primes.
I recognize others may not agree, and I have read the reviews on the DFA 24-70 and it is better, but for me the Tamron 28-75mm fits my purpose and budget, and I have taken some pics with it that I really like.
