As some may have seen on another thread; my Sigma Aspherical IF 28-105mm lens vignettes pretty badly when backed all the way out to 28mm. This is a really annoying development (no pun intended, well maybe...) and leaves me with just a 50mm lens to use with my Minolta 450si.
Does anyone have a suggestion for an alternative lens. I like the versatility of the zoom; my wallet won't let me buy, what would amount to, probably, three different prime lenses. So, what's a cheapskate like me to do?
