I like the
P50 more which is closer to P30n.
As pluses:
-P50 has Aperture priority, Manual and Program (two programs)
-DOF preview (ME Super does not)
-The readings in the VF are very clear and very easy to read and does not thave thet annoing for me, OVER/UNDEREXPOSURE signals. Just indicates you the right and exact shutter speed to select (blinking light) and the selected speed (continuous light). Much, much more easy to work in manual mode this way.
-Has exposure compansation with +3EV and -3EV in half steps (0.5EV) (ME SUper has only 2EV I think)
-Has Exposure lock (ME Super does not have it)
-Has top LCD like modern d/SLRs
-Has buttons for setting the shutter speeds, the exposure compensation, the operating modes which can be done using only one finger not like the dial which, at leas in my case, I need two fingers to operate it. (same for ME Super and A series)
-The light meter seemd to be very good , precise and reliable.
-Same ME winder can be mounted on the camera.
-Looks and is a sturdy little camera even if has more plastic in its construction than the M and K series.
and other pluses.
-Easy to find and cheap batteries.
Minuses of the P50 ans P series:
-ISO of the film can not be set manually. The camera reads the DX code of the film. If no DX code is detected the camera uses 100 ISO as default.
-smaller VF than ME Super (the magnification).
-No mechanical speeds - does not work without batteries but the batteries used are easy to finf and cheap.
-No 1/2000 and 2s, 4s shutter speeds like ME Super but the same speed as K1000 and MX (1/1000 to 1sec.).
I made here a small review of it but it is in Romanian
