Advance problem in Asahi Pentax 6x7 PART 1 motion lapse film 

I thank you for sharing as there are very few repair vids for this camera. Better than nothing and wish you would make more on this model.

Solved my problem thanks soo much!

Fixed my shutter winding problem. I had been dry firing it by holding the frame counter forward and closing the back. It felt as though something had broken. I put a new lr44 battery in it took off the lens and metering prism. The I put it all back together and put a film in it . Winds on and everything is working perfectly now. I have a 6x7 and a 67 both in mint condition. I have a newer rubber grip 55mm F4 and an older 75mm 4.5. Both are sharp. The 75 exceptionally so. Although it has to be used with a lens shade The 55mm can be shot into the light with no hood. Good contrast and no flare. No more dry firing for me.

Yes! Thank you!

You could put a video on Pentax Soptmatic F ?? the eposimetro fails. It would greatly appreciate it . you do a great job. thank you very much .

Hi there. have you ever taken apart the right hand side where the wind lever is? im having trouble where my wind lever doesn't lock and stop once you get to the first frame. any help is appreciated!

I know its an old video, but thanks it just saved my camera.

Hi Mike, thanks for sharing! What type or test film/ brand are you using on your video?

Hi, I've got an old 55mm lens for this camera with a fungus right in the middle of the lens. Do you know how i can open the front part? Thanks a lot for your videos, I could clean the oily blades of my Mamiya 645 80mm. Thanks a lot for sharing all this information/education. Have a good year!!

Hello. I have a pentax 67 that I haven't used in years. I decided to start experimenting with it again. it was stored with the battery removed. i got a new battery, the battery checked good, and the light meter in the ttl viewfinder worked. i went out to try to shoot the remaining film that was in the camera (was in there for years) and the battery was dead. i put another new battery still nothing. i also encountered the problem of the film winder lever will not turn, it only advances about an eighth of the way along its path, and the shutter release will not fire.

I have a prob with my film loader spring on the left of the camera. Is there a way i can send you a picture and maybe you could help

Hello.i am using the pentax 67 with the 75mm f4.5 lens and when turning the focus ring until the infinity sign and aiming to a very far object i need to turn the ring a little bit back to get the focus right.is this called 'focus past infinity'? And what could be the problem causing it? Please help me if you can..thank you.

Can you explain what is happening on the right side of camera? Because my cameras advance lever slips whenever I try to load a roll, but I’m sure my camera works fine because when I trick the camera into thinking it has a roll it shoots perfectly fine.

Hello! I did it as you show with my Pentax 6x7 MLU and it did not work. Do you know why could this be happening ?

This is the exact problem I have! Where did you get the lubricant ? And how careful show you be putting it when you take of the shutter speed dial. I couldn't see clearly exactly where you put the lubricant there Thank you so much

thank you for sharing this, i know its an old video, but I hope you can answer 1 question. I see that most of the lubricating is done underneath, at the spool end. is it absolutely necessary to open up the top to also lunricate there? i notice most of the lubricating occurred in the area that required no dismantling. from what I could tell the only thing that was done on the dismantled part, was some lubrication to the top of the spool on the inside. did I miss anything, or is that the only thing done there? I am hoping to avoid dismantling and give the area som needed lubrication.

Where do I get that lubricant?

Do you know what size screwdriver you are using on the shutter speed knob?

Hey, can you say what kind of lubricant you used here? I just got one of these and am having some trouble with the film winding mechanism, myself.

Hi Mike! I don't have this exact problem but thought maybe you could help me. In a lot cases in which I used my Pentax 6x7 there were a lot, or sometimes one or two frames that were left completely unexposed. As long as it were 1 or 2 frames I though the problem was due to bad lighting, that it was my own fault. Upon developing another roll this very afternoon I noticed only 1 photo was exposed while I am very sure that all photos were taken with the same shutter speed, the same lighting conditions, same aperture, in the space of an hour. The chances of not properly exposing my photos were slim in that case. Thus my question; do you have any experience with the Pentax 6x7 models having a "frame skipping" problem? If so, have you ever found a solution? If not, any idea what the problem could be? I have tried replacing the batteries and cleaning the contact points of the shutter speeds but none of these seem to solve my problem. Thanks in advance!

mine does not advance the film properly, so exposures overlapping, how could I fix that?

I have a similar problem. The camera only generates 9 frames in 120, since the spacing increases progressively as the film progresses, leaving no space for the 10th frame. What could it be?

Hi, my Pentax 6x7 has this problem: instead of take 10 pictures It games only 9. I'll try to fix It by myself, do you have any vídeo that shows boa to do It? Thanks!!!

Great video! Do you think WD40 would also work?

I suppose that one in a hundred Pentax 67 bodies my have a stiff film advance because of some internal problem, but the other 99 units will be stiff or jamming film in mid-roll because the user doesn't bother to read the instructions and loads the film improperly. Specifically, you must load a new film roll with some tension retained on the roll as you initially advance the paper roll to the starting point. That initial loading must maintain tension on the roll and not be loosely loaded as was shown here. If you do a loose (sloppy) initial loading, the shot film and paper wraps too loosely on the take-up spool, expands too much in the take-up chamber and will jam as a result. It's all right there in the instructions, but who read instructions for such a basic camera? ,Yes, I learned this the hard way. Comment on video: sign language may have worked okay for the plains Indians, but it doesn't cut it in this venue.
