Just a thought, if it is always at the same height, but not the same position across the negative, could it be a light leak through the film door by the hinge, there is supposed to be a full length of felt strip by the hinge. This might explain why it is there only some of the time: how quickly you go to the next shot, your hand covering the leak area, and as the film gets wound on the spool, the diameter changes and hence not always the same spot on the negative gets hit.

Yeah, it was a mean thing to say: cutting the shutter life in half, but when they say the shutter is rated for 100 000 shutter activations, you do only get 50 000 pictures. The shutter is normally open and the sensor feeds the picture to the evf. When you want to take a picture (let's say not with the electronic shutter), the shutter has to close in 'preparation' to take the picture, the lens stops down, shutter opens and records the information and then closes (just like a DSLR). After that the lens opens up again, the shutter opens and and the data is fed to the evf again. A DSLR operating in live view does the same thing. Now a days a lot of mirror less cameras have electronic shutters which does not wear on the mechanical shutter.

I just got to chime in with my two cents on this one. I for one greatly appreciate an optical view finder: the vertigo associated with the lag of an EVF just does not sit well with me. Now, I have not recently tried a high end mirrorless camera, so it may be way better now than when I was shopping for a new camera (that was my K5II), but a fast refresh rate sucks a lot of battery power. Anyway back to the main point (or two), a mirrorless camera actually does two shutter activations when taking a picture. This means that if my K5II, rated for 100 000 actuations, were a mirrorless camera, it would be good/rated for only 50 000 pictures (don't think I will get there), but for the professionals (or those that take a lot of pictures), a mirrorless design cuts the shutter life in half. Secondly I really appreciate Pentax's on going support of the K mount, and I think a lot of Pentax users really appreciate that loyalty as well, which makes for a lot of loyalty towards the Pentax brand in return.

Hi Bernie , this may sound like a more difficult way to do this, (because of the tools involved), but it is easier. The interface between the pan head and the mounting plate is probably 2 1/2" to 3" across the amount of friction/grip from that surface area is way higher than the actual torque/friction of the bolt (even with lots of threads its less than 1/2" across). Take a flashlight and look up inside the column, you should be able to see a bolt head at the top holding the plate and pan head on. Using a socket and extension(s), and ratchet you should be able to just hand hold the plate/pan head and undo that bolt - you will need to turn it enough to unwind the 'threaded portion' in the pan head. Remember counter clockwise.

I had a similar problem with a Manfrotto tripod with a tilt/pan head. As mentioned earlier this one also had set screws accessible from underneath that prevented the head from loosening when panning. Even after loosening these set screws I could not get the head to come off, what worked for me was using a socket on an extension (I needed two to reach) and accessed the 3/8" bolt from up inside the center column (I did have to remove the hanger from the bottom of the center column).

Sounds like the second shutter curtain is not closing completely. You could very gently nudge it down: I think there was a rivet attaching a hinge/linkage piece that I used my fingernail to push it down about level with the bottom of the opening for the negative. My camera would continually hang up though doing the hundred shutter releases suggested above might have worked

The red K50 would look so good sporting those old classic black KA mount lenses that hang out with my K1000 right now.

Recently found myself with a lot of extra time on my hands (divorce and such), so I thought to resume my old hobby and dug out my K1000 and started to play again. This forum/web site has been the source of a lot of good information: like how to replace the seals and such - thanks!
