Hey Lee, I noted that you have a
Minolta AF 35-70mm f/4 lens in your bag and I was wondering how much you are using it?
I have found that with digital, I have gotten terrific results by changing from that lens to the
TAMRON SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) MACRO lens. Not only does it provide you with a tad more range, it is exceptionally sharp by comparison. Heck, it is my "walkaround" lens, outdoors. If you are really looking to improve your image results, you might want to consider something along those lines. The cost is reasonable, compared to what upgrading to a
SONY CZ 24-70 f/2.8 would be.
Just a thought.
