I just got my K3 but the internal light meter doesn't seem to work. I'm not too worried as I have my own light meter but I was wondering if there was any light loss with the K3 regarding the viewing system and also what the shutter angle is so I can calibrate my light meter with the camera.

Thanks in advance for any help.

Hi Jon,

I'm not sure of the shutter angle but I've used the shutter speeds published in the K3 manual which seem to work fine:

The K3 is notorious for light leaks, I always like to tape up the edges of the plate after loading the film. Also make sure you have your eye up against the eyepiece while running the film or use something to make sure there is no light going into the eyepiece when the camera is running.

Thanks for your help with the shutter angle. Regarding my first question, I don't think I explained my problem clearly. I'm not referring to light leaks in the camera although I will take your advice and use tape. What I meant was will I have to compensate for light being eaten up by the viewfinder (I'm assuming K3's use split a prism viewfinder)? When I use my canon 814 super8 camera I have to compensate 1 stop on my light meter for the light being eaten by the viewfinder. Will I have to do the same with my K3?

Thanks

According to the manual the K3 has a mirror shutter, not a prism. No light loss there.

Hi Jon,

Here is the manual: http://www.k3camera....s/2004k3man.pdf The shutter is as mentioned a rotating mirror, so no light loss to the viewfinder. Good luck!
