Thank You Kim I understand it now

By the way I'm happy that I can thank You personally for pentax-manuals. I already downloaded some from Your site

Hello everyone

It is my first post here so "big hello" to all PENTAX users.

I came here with a question about MX light meter. I'm not sure if it is normal but a guy who I bout MX from said that it is normal, the thing is that depending on the film sensitivity the light meter is not working. For example is if set ASA 400, the light meter works only for shutter speeds 1/1000-1/4s...if I set ASA 200 the light meter works for 1/1000s-1/2s, for ASA 100 it works for all shutter speeds and so on...

If it is not a camera failure, can anyone tell me plz what are these limitations for ??

Hey,it seems that it is mechanical problem because not matter if the film is loaded or not the film counter (You are asking about it right??) works.
