Try cocking the shutter with the camera back open, if that does not pop up the rewind button the camera may need service and lubrication.

i dont have a solution trying to find out the problem

The diopter adjustment control is just above the viewfinder. See page 23 of this manual: http://www.fixya.com/support/p154048-pentax_zx_30_35mm_slr_camera/manual-2619

Some batches of the ZX50 were produced that only put out 2.6V instead of the 3.0V printed on the label. Check your battery with a volt ohm meter if you have one to ensure it is putting out the full 3.0 volts. If not replace with a different brand of battery. Hope that helps,Bax

If you are using standard or "Heavy Duty" batteries, this is not unexpected. Try Alkaline or even better, rechargeable NiMH batteries, they have a much longer life. Some of the earlier digital cameras were real power hogs.Hope that helps,Bax

If I'm reading the specs right then the N73 works with SD cards. Your 4GB card is actually an SDHC card and will only work in devices specifically designed to work with SDHC cards. You'll need to use SD cards, 2GB or smaller.

Pentax makes a number of different 50mm lenses. Which one do you have in mind?

Probably there are none.

Probably there are none.

How funny is the noise?

K1000: Remove counter cover (3 setscrews around perimeter), remove counter disk (screw is right threaded - turn right to remove!!!!!), washer if not glued to bottom of disk, round nut with slots (also right threaded), lift off counter base, three advance lever spring screws, turn spring until loose, remove advance lever, remove washer underneathK2: using a rubber stopper, and downward pressure on the cap/ cover screw, turn to right (this cap screw is right threaded!!!)If you try and turn it like you would a normal screw you will break it off. If the camera has corrosion under the cap screw it may stick - try heating with a soldering iron (careful the screw cap will be very hot). In extreme cases I have drilled two holes (one on either side) and used a pair of round nose fine tip pliers to turn it.Unsure of which model you have as both are mentioned in post

I assume that this is a film camera that has light meter.It could be that the camera is set to a different film sensitivity than the actual film.For example, the film is 400 ASA but the camera is set to 100 ASA.The sensitivity rating of the film is written on the film box and on the film cartridge. Make sure you set the film ASA number on the camera too.

is the mirror stuck up? Lots of these ZX Pentax models have failure of the mirror motors when the plastic gear on the shaft of the motor cracks and then the motor just runs continously
