Just bought the following....
Pentax MEF (good condition, needs batteries to see if it works)
Pentax 50/2
Mamiya 28/2.8
Vivitar 70-210/4.5 (doesn't mount on my K-x for some reason)
3x teleconverter with electrical contacts
Minolta 132x flash
A few various filters
Bag for all of it
For a grand total of....
$40!!!
First thoughts on everything:
MEF: The viewfinder is HUGE!!! DSLR's got it all wrong!!! It feels so solid! I think I may be in love. Need batteries and film to use it though.
50/2: Nice and small. Haven't had any real chance to test but should be good.
28/2.8: Love this FOV. A bit of internal dust. Also on the petite side.
70-210: Doesn't mount. Something is preventing it from twisting on. It is really, really slim! Also it doesn't actually extend zooming, the barrel just "moves" over the inner tube so to speak.
3x teleconverter: Well, it's a teleconverter.... good build quality, electrical contacts (
) , good macro focusing.
132x: No batteries to test it with ATM (or method to trigger it - may fry my K-x?)
