Ahhhhhhhh So my weekend turned into a month away.. that's what happens when you go to New York and then find out while your there that a close friend has passed away and then your parents are vacationing in Nicaragua so you have to tend to your 91 year old Grandfather... but I digress.. I'm back.. and I have a question regarding a K-mount manual focus lens.
I spotted a 20mm F4 SMC Pentax (no M designation) around town and I was curious how it compares to the Pentax-M version - are they the same? (virtually)? Boz's site lists it as 10 elements in 12 groups vs the 8 and 8 that is the Pentax-M - it's heavier than the M and longer too but how does it compare optically? Anyone have any ideas? Thanks, Dave
