I am looking for a replacement zoom lens for my 600si, and mainly looking at the 24~100mm zoom range. With a budget of around 500, I have narrowed my choice to the minolta 24-105 D with cost around 550 (from the lens thread)
1. Would the lens cause shadowing if i use the built-in flash? If so would it appear throughout the zoom range or only when the lens extend till a certain limit?
2. Given my budget, are there any other choices (3rd party)? My main criteria is the WA of 24mm. The top range of the zoom is arbitrary, but shd at least be 70mm. Hopefully it should also be light. I am only a hobbyist and any lens which is optically comparable to the KIT lens is accceptable
3. I have seen that there is a sigma 24-70 at only around 200?? is it still available and any comments on it?
appreciate any feedback
