I've never been a zoom person. Instead I prefer fixed focal length lens. Recently though I bought a Minolta manual focus 70-210mm f/4 lens in part because of its reputation. It does live up to that reputation.. I also purchased a Minolta manual focus 35-70mm f/3.5 and it too is an excellent buy.. I have since been told the 28-85mm f/3.5-4.8 and 28-105mm f/3.5-4.8 are both as good as the above and even though there is an overlape of focal length I am thinking about giving one or the other a try.. Any experience with these lens?? Which do you think is the better and why?? We are talking about the manual focus versions not the autofocus ones...and they would be used on Minolta srT's, XE-7 and XD-11 cameras..
