What lens did you use?
I've been buying all the old Minolta glass in the thrift shops around here, some is junk but i've found some really good lenses.
I picked up a Minolta MD 28-70 yesterday, it looks like new.
I've even pulled a few down and tackled fungus infestations.
I'm retired, can't do much physically and I hate just sitting, I make sure I always have something to mess with!
