Just for a quick test, I stuck the 50 mm Macro lens on my K100 body. Without much thought, not even a tripod (which I always use for CU's), following the old Sunny 16 Rule...I got some nice shots of Russian Sage in bloom. Why can't the K-30 be as easy? What am I missing???
The K-30 is (
almost) as easy as the K100D. On the K100D, you would have to enable the aperture ring in the custom menu, then (1) put the camera in M mode (2) set/check your ISO (3) set your aperture on the lens, and (4) press the AF/AE lock button to stop-down meter, then tweak shutter speed (or you could just set it manually using Sunny f/16).
For the K-30, the only difference is the button used to stop-down meter was moved to the "Green button". Also, you have to manually select an ISO (I can't remember if auto-ISO worked in Manual mode on the K100D or not). On the K-30, if the ISO mode is "Auto-ISO" with an M lens, then it holds the lens wide open and tries to come up with a useable ISO/shutter combination, which most folks find annoying.
To turn off Auto-ISO, press ISO, up or down (whichever, so long as it has the box around a single ISO instead of a range), then OK.
Once you are composed and focused (the camera, not
you personally
), just press the Green Button to meter, check the settings, then shoot.
