Not rare, but not common either. I have never tried the 28-50mm I got for a bargain price one day. But I used the 24-35mm and both zooms share the same style and construction (very high quality). I have seen a test in Camerart (Japanese magazine written in english) on 28-50mm lenses. It was the smallest one and not as good as C*n*n's big and expensive 28-50, especially wide open. I'd use it at apertures smaller than 5.6.Are these good zooms, in terms of image quality? Is the 28-50 a rare lens?
