IMO these threads about lenses can end up with people reporting what they may have read, rather than having used lenses themselves, so many myths and legends can get repeated.
Re my comment earlier that the 35-70 f4 is the lens I most often take out with my OM, yet many will tell you its just a "cheap consumer lens", so I thought posting this little example might help. This is unaltered straight from the neg scan. The signpost is pretty readable considering its small size in the original n'est pas?
You can get the 35-70 f4 for around $40. Its a steal.
