is the pentax 67ii NOT a cold weather camera?

That's interesting...

I have used my Pentax 67 in minus 6c temps at the snow this September without any problem — if anything, it was me who complained about the cold!!
I do not know about the 67II, but a separate cold-weather battery attachment is available for the 6x7 / 67 which allows for a battery to be kept in your pocket, tethered to the 6x7 / 67 by a cord. You might also want to try a lithium battery to get some leeway over cold weather performance.

Authenticity of Pentax 67.

Some Pentax 6x7 (1969 onward) or later Pentax 67 (1989 onward) bodies may have been repaired with parts taken from other cameras, such as the top plate, winding lever, TTL or non-TTL prism, power on/off button, mirror lock-up lever (silver instead of black)...

The camera shown here is ordinary and unremarkable in its presentation as a Pentax 67, and is not a fake! It is the mirror lock-up version, and that is undeniably useful. The TTL meter prism is the modern, updated one that came after the ASAHI PENTAX-badged prism. The two (old and new) are interchangeable.

I need to ask you, in what way, beside quoting a serial number and the reams of incoherent discourse on the subject included in your post, do you consider the camera shown to be fake or suspect? To you, as a new user, it could probably be anything under the sun! To me, it is what I use every day and it does not look like anything else.

Having got that small matter out of the way, other things:

Reliability going forward may be an issue. The 1969-vintage cameras are now very old (the one pictured here looks to be from 1990) and are the usual suspects for things to go wrong. In any case, the camera can and probably will break down at some point indeterminate, because of age and likely heavy professional use many years ago. Occasional failure points are the winding mechanism (slipped, overlapping or incomplete frames), sticky mirror solenoid, aperture coupling chain, derangement of shutter speeds (store the camera with the shutter speed dial on B when not in use) and battery compartment corrosion. Foam seals on the underside of the TTL or non-TTL prism will require replacement at some time. This is a tedious and grotty job. Failure to replace the foam seal can result in very easy dislodgement of the prism, sending it crashing to the ground. Once the seals are replaced, the fit will be tighter and thus more secure and more effective at sealing out dust.

The Pentax 67II is an updated/modernised electronic version of the earlier cameras and was released concurrently with a revised set of lenses (designated SMC Pentax 67). These replaced the earlier, older Takumar and Pentax 6x7 lenses with improved optical and handling characteristics. Some of thes lenses are very expensive, even now -- a reflection in their optical performance, when used competently.

Your attention is also drawn to a much more important point: the correct way to remove and replace the TTL meter prism in this camera:

https://www.pentaxforums.com/forums/48-pentax-medium-format/372920-link-sticky-pentax-6x7-67-all-variants-meter-coupling-chain.html

A broken meter coupling chain will hobble the camera and result in you having to use stop-down metering until the camera can be repaired (which is best left to somebody like Eric at pentaxs.com, who services these cameras).

Spare parts are not available for any of these cameras because of their age; parts, when required, are taken from like-cameras for repair, and this introduces continued questions of reliability long-term, but you should still get many years of service from a well looked after camera (but it is not guaranteed without knowing the camera's history -- how it was used). The same though cannot be guaranteed from a heavily used or abused camera, so as always, Buyer Beware. A camera may be described as "mint" but it is not underneath, in the mechanics, probably having exposed thousands of rolls, even if it was babied and looked after. I am irritated by persistent descriptions of mint or near-mint in eBay listings of these cameras: they are far from mint and the term is more often than not used to encourage consideration of the item ahead of others, but it is a herd mentality!

I don't develop it -- I'm moving around every day (right now, on a train to the Big Smoke). I throw it in the lab pigeon slot and they get it done while I continue my crusade to save the world. They do use Adotech IV as standard though and go through a lot of it, particularly after main holiday periods, and presently with universities and schools on holidays. CMS II is the Hipsters' film of choice...:) I forgot to include Ilford's lovely Pan F+ 50 in my list. It's there now. I haven't used it for a while but hope to get a few rolls through 35mm with 17mm ultra-ultra-wide at a wild beach in the coming weeks.

Unload the camera, even if it means sacrificing it to light, and examine the roll of film for any adhesions.
Second, examine the right-hand side take-up spool. Put in here an empty spool -- DO NOT LOAD FILM, and operate the wind-on lever. The spool should move with the winding motion in a gentle tick-tick-tick-tick feeling. The issue though may be that you did not secure the end of the film leader into the 'catch' of the spool, which has caused the film to not be engaged and by association, not fully moving across as a full frame each time the wind-on lever is operated, causing double exposures.

If after this check the same thing happens with the next roll, it could be a broken or stripped winding pawl in the wind-on lever. With very old Pentax 6x7 cameras (I haven't seen it as commonly in the newer Pentax 67 cameras) and those subject to a lot of heavy professional use, this is a common failing. Eric Hendrickson at pentaxs.com would be your next port of call for examination, and hopefully repairs. New parts are not available so replacements are taken from another camera for repair.

This is excellent insurance for the exposed roll. In my pack are a few sheets of pre-cut pieces of foil for just this purpose.
The other method, though bulky, is to use discarded M&M containers, in whatever colour that tickles your fancy: green for unexposed, red for exposed, yellow for part-exposed, pink for dudded, white for 'no idea'...:lol:

The 67 has dovetail sealing along the edges beyond where the seals finish.

It is well within anybody's remit to trim the Aki-Asahi seals to suit, and if you find seals as shown in your camera like that, it follows that any replacements should be identical to what was originally fitted.

Light piping through some sort of damage or extreme wear to the back cover is rarely seen. But light piping through incorrect film loading and unloading is very common!

Light piping and some sort of residue before or during processing.
There is nothing wrong with the foam seals on your camera.

6X7 55mm Lenses

A 67 and 55mm was spied nearby here yesterday; he is a student from Melbourne (76km away) and only on his second outing with the 67.

I would not go back to using the 55mm; it just did not feel right for the task in the landscape context and I itched and twitched in search of going wiiiiiiide... If you come from the ultra-wide spectrum in 35mm, say 16, 17, 20mm... there will be no escaping the little voices that tell you to go wide in MF!

That said, the all-seeing 45mm f4 has a gelatin filter holder at the rear (it's funny how so few people owning this lens are aware of this!), while the 55mm does not. Whether that is significant or not depends on individual circumstances in photography and the availability of gelatin filters (they are not quite scarce, but they certainly are not cheap).

Internal rattles with the 55mm are a persistent theme among users. No idea if the earlier 6x7 55mm had such a malaise.

"Artistic route" portraiture. Hmm.
Does your 67 have the (rare) multi exposure facility on the right-hand side of the camera below the 120/220 film format selector? Cameras with this have been used for very interesting special effects using multi exposure with one lens or two over xx number of frames (no limit). I am attempting to find the fellow who did some of this here in Australia. I do have the ME facility on my 67 and that is only used in the landscape context, and not immediately evident when it has been applied!

My vote is for the 45mm for landscape use and the 165mm LS (as per Tuco's example) for portraiture. Alternatively, either of the 90mm lenses are also good.

I have owned the 55mm lens but became annoyed by its clunky design, stiffness of focusing and overall lack of refined 'feel' compared to e.g. the squat 45mm and the elegant 75mm f2.8AL. That said, I created three of my all-time greatest images with the 55mm back in 2012, but I do not miss it.

I agree. Additionally, if you get your hands on either a 90mm f2.8 or 165mm f4 leaf shutter lens, you can then use studio strobes with higher speed sync than the camera's native 1/30s. I do not do many portraits, but the one I made was with an ordinary 90mm f2.8 lens.

A couple of weeks back a 6x7 appeared here with a rear cover removal nib visible in the side-on profile. The owner was not aware this was for removing the back cover easily compared to the method you have stated! I think it was a factory modification, rather like the multiple exposure facility was.

That MLU-optioned camera dates from around 1976, so it has quite a long vintage and will require care.

In professional practice, a polaroid back was most often used for proofing a shot e.g. lighting/poses etc, before substituting for roll film, in the same camera or in a second camera.


It should be possible to remove the Polaroid back and replace it with the original back for the Pentax 6x7 / 67 camera. Your problem from there is finding a replacement cover; they are certainly not made new so you might need to go through the eBay or used / second-hand dealers, possibly even purchasing another camera — yes, just for a back!!
Did you actually ask the seller if she knew if the original back was within the kit? You never know, she might just need a clue as to what it looked like among all the other stuff.

Another option is to run an enquiry to Eric at pentaxs.com who repairs these 6x7 / 67 cameras. He may be able to assist with a back, otherwise you are stuck with the Polaroid, which is not ideal.

Yes, as with Phil's response, match the position of the pressure plate with the film -- 120 or 220 (220 has no paper backing and is thus much thinner). I was also thinking of a winding mechanism error e.g. a partially stripped pawl that does not fully advance the film before the next frame. Also incomplete wind-on: with all of the Pentax 6x7 / 67 cameras (which designation do you have?), film winding is accomplished in one whole, complete stroke of the lever.

All images from Pentax 6x7 out of focus

I am suspicious of the focusing screen, not the prism.
When changed, the focusing screen must be carefully calibrated for focus at 3 points in the centre. It is not a drop-in-and-forget task. Or, if something like the meter coupling chain was broken and repairs were done, was the lens mount and focusing screen then collimated to specification? The possibility of a distorted mirror box comes to mind, but really, your best option is to have the camera professionally examined, even if the cost of doing so and any required repairs outstrip the net worth of the camera

There is a depth and breadth of active professional and amateur photographers on Pentaxforums.com that can provide a lot of advice on analogue matters. It is also the case on Photrio, although it is often a challenge to find which advice is best, correct or right for any given situation with so many opinions, claims and counter-claims! ;)

This advice is also published in the owners' manual originally supplied with Pentax 6x7 / 67 cameras.

Your point is entirely valid.
I too, would strongly suggest that photographers making the move up from the relatively high-levels of automation and 3D metering of 35mm come to an effective operational competency with separate, hand-held incidet/spot metering techniques as an effective standby workaround. Unfortunately, many do not and have no interest in doing so. Many still are completely blithely unaware of the fallability that is the purpose of this sticky!

As mentioned.
Chains are taken from other Pentax 6x7 /67 camera bodies, typically those no longer operational and assigned for "parts".
Thin, multistrand jewellery beading wire is the usual fix in the absence of a suitable chain from another camera body. This ultra-flexible material (bonus: many colours to choose from! :lol: ) is much stronger than the native chain, but does not negate the precision required in disassembly, fitting, reassembly and calibration.
