Originally posted by Snappertim The Pentax film era camera you want for 35mm full frame and robust build quality that directs all no apature ring lens from the body, (and also lets you set the apature from the ring if the lens has one) is the MZ-6 (or MZ-L if you are in north America), its a fully specified camera and the same size as your MZ-S.
What makes that camera better than the PZ-1/PZ-1p (Z-1/Z-1p) which was already recommended?
MZ-6 lacks center weighted metering pattern
has smaller bracket range
has much slower flash sync speed
lacks hyper program and hyper manual modes
2 fps slower
doesn't support power zoom
can't change focusing screen
lower magnifcation viewfinder (.7x vs. .8x)
weaker onboard flash GN11 vs. GN14
does not support flash exposure compensation (onboard)
uses a pentamirror vs. a pentaprism (Pentamirror is much less bright)
it does have 3 autofocus points vs. the single one on the PZ-1 series
It is lighter (400 vs. 650g)
it can have a battery grip (4xAA)
