I had to fix mine two years ago.

Pentax does sell the part. If you call service center, they will email you a schematic. I think I spent around $9 us for the parts.

I order the repair manual from eBay, was helpful. Leatherette needs to be removed and then the top cover.

This is actually a Large Format type question, as You may not find a Medium Format lens with a cover circle for the 617 format. Distance from the mounting flange to the film plane is not the same for all lens. Also have to consider the shutter type you will also be using.

Check out the list at this site for lens cover circle: http://www.largeformatphotography.info/lenseslist.html

I have a 617 camera with a Rodenstock Grandagon that has a cover circle of 221. This is measured at the min f/stop. it is reduced at wide open.

Good Luck

Used your title and 10 secs at Google

Did you read this line in his auction?

"ALL ITEMS ARE GOOD USED CONDITION UNLESS OTHERWISE STATED."

I would have asked for more images any many questions. The marked "new" is an ebay thing, most seller ignore picking the correct selections. But he does state in the auction it is used and a very bad description. Personally I would not purchase from this type of presentation.

The 67 35mm is a fisheye lens. It can be mounted on the 645, but still a fisheye lens. You will have a cropped fisheye on a 645. The 645 35mm is considered a wide angle lens. Two different animals.

November 9, 2009

Still two, I did not have my info near me at the time so I took a stab at it. Picked the wrong format for the shorter lenght, the one I don't own.

You can have flash sync speeds up to 1/500. Get your self a 75mm and/or the 165mm Leaf Shutter lens. Solves the problem.

October 29, 2009

Were you using a Lens Shutter? Most cameras require the focal plane speed in the 1/30 to 1/8 range for the lens shutter to expose properly. I guess we need more info instead of guessing.

October 29, 2009

My guess you images taken with flash and using shutter speeds greater then 1/15 of a sec. The manual also has x-sync at 1/50. Electronic Flash at 1/15

Vertical Focal plane shutter. Images crop at the top or bottom? On a good roll measure the Image spacing and compare to the bad roll of film.

September 29, 2009

I'm going to try a ninja suit at the next shoot. My body is much larger then the camera in a reflection.

September 29, 2009

I wish the current line of cameras were covered in the the old standard of leatherette. Nothing like walking into a room with a camera deck out in red lizard skin or cobra.

May need a cleaning and lube then.

September 8, 2009

I'm sure you won't find an adapter. If you do get it mounted you'll never get infinity focus, becasue the lens is mounted at a greater distance from the film plane. And if you solve that problem you have 43mm to 46mm image circle.

Goodluck

Check your battery. How old is it?

You are right, they don't. They don't have any thing for a Pentax 645 either, but when I asked in an email they told me some cameras are not listed and if your camera pattern does not exist they can make one.

September 4, 2009

The Pentax 3G for the 6X7 will work on the 645 with the 6X7 adapter. I have only fitted to my 645 and never took a shot. Just playing with it was cumbersome. If I have spent more time with it, I may come up with a plan to use it on my 645.

Lensbaby made a 100mm version for Pentax 67, Hassy(I think), and some movie camera. The 35 mm version is a 50mm lens.

"Try this before you get to involved. Much easier to do with a digital camera. If you can mount the lens on a digital frame."

Trying to find the "Entrance Pupil" with film. Take a group of pictures to fine tune the position. Take film to lab. Wait one day or a week.

Trying to find the "Entrance Pupil" with MF Lens mounted on Digital camera. Take a group of pictures to fine tune the position. Minutes later the results is seen and zero cost.

Does that help. I have found the "Entrance Pupil" on many lenses. Just try to find it by looking through the view finder is not accurate, it will get you close. I have found close enought does not work well with programs like "PT Gui" the errors are to great and I have spent to much time repairing images.

What you are looking for is the "Entrance Pupil" This is one great site for all your panoramic needs. <a href="http://www.johnhpanos.com/">http://www.johnhpanos.com/</a> <a href="http://www.johnhpanos.com/epcalib.htm">http://www.johnhpanos.com/epcalib.htm</a> <a href="http://www.panoguide.com/howto/panoramas/panohead.jsp">http://www.panoguide.com/howto/panoramas/panohead.jsp</a> Try this before you get to involved. Much easier to do with a digital camera. If you can mount the lens on a digital frame. You could dial it in closer, otherwise you will process a few rolls of film. Another option, use a viewfinder magnifier to find your point of no parallax

Hand out that disc. I would give them images at reduced resolution. Nothing greater then 1600x1200. They can have 4x5 mades that will look ok to them. Let them post them everywhere.

May 19, 2009

Could check this link to the press release for that camera. From the press release it reads that it is new design, so I don't think you will find a film back for that model.

Now that Horseman is out of business, that info will be hard to find. You could ask the same question on the Yahoo group "617", as someone from Horseman is on there to answer questions all the time.

That's interesting, when did Pentax change their press release to worldwide? They were not going to sell it in the US only because they felt it would only sell 250 units.

April 20, 2009

I would also suggest the battery change and reset button.

Time to invest in a "dark bag", most camera shops would help you out in removing the film. It is a shame you had to waste it.

Could download the 67 manual from here.

Hey Edward

The search function of this forum is krap. You can not use two or three word searches or direct the search to a forum. If you search the Pentax 67 forum the search function uses ALL medium format forums. Two word search return all post with either of the words searching for.

Beside why would anyone want to reply to a post from a year ago or even 6 months ago. It will stay buried among all the other replied to posts. Sure just subscribe to the post. Now my email box is filled with various post. I would still have to come here to sort the messages.

I have complained the Admin and they don't seem to care either.
