In the 6x7 world there was a batch of helicoid extension tubes that went out marked as "hericoid" instead which is a little harder to understand.

I wouldn't call it a 1.5, it isn't really an intermediate model, just a variation. I have two model II 500/5 and they are both different and all three copies I have of the early Takumar 500/4.5 are different.

Old 6x7 Brochure
Posted By Paul Ewins
Replies: 9
Views: 813
This is from (more or less) the second era of brochures, possibly produced around the time that the 6x7 was first actively marketed internationally. The lenses are all Super-Takumars but the cameras have already been upgraded with the mirror-reset buttons and have the familiar slot style of film type select switch. The first series of brochures used photos of the chrome and black prototypes and had non production (possibly retouched) serial numbers on the bodies. Since the manual that shipped with the earliest cameras was a correct reflection of the production camera I would think that the first brochures were prepared well in advance of the system launch.

Another interesting point is that all of the early brochures list a 135/4 Super-Macro-Takumar but as far as I can tell this was only ever available as the Super Multi Coated Macro Takumar. Likewise the Reflex Takumar is listed as 1000/7, not 1000/8. These were the last two of the initial range of lenses to become available so presumably there were tweaks between announcement and delivery.

Possible Age of 6x7

The cutover point from 6x7 to 67 is around 4159850. As pointed out earlier these cameras were often upgraded or simply repaired using newer parts and the winder side top plate is a common replacement, probably due to shutter button issues. It isn't unusual to see a 67 with a serial number lower than this, however the only 6x7s with a higher serial number that I have seen are ones that have the double exposure modification which replaces the winder top plate. Presumably these were done with old stock parts from the 6x7 era.

Ok, this is a fairly nerdy collector thing, but getting a pair of lenses with consecutive serial numbers is a really difficult thing to do. Usually it's because a pro or rich amateur bought multiple copies of a lens at one time and eventually sells them. In this case I happened to be looking for this specific lens and while comparing prices and condition of the eBay listings I noticed that these two lenses had consecutive numbers. The really unusual thing is that they were two separate listings, one from Japan and the other Australia.

Although they didn't use the Pentax name on a camera they did use it on photographic equipment, although to be fair this film editor is the only non-Asahi photo item I have ever seen with the Pentax name on it.

No, I spoke too soon. That's another one I need. Also found that there is a Penta Asahiflex H2 compared to my plain Asahiflex H2 so I'm back to needing two more to complete the set.

I think these were the last two bodies I needed for the Asahiflex/Tower collection and they both turned up on eBay within a week. There is still the 83mm to get and all manner of sundry bits too I guess.

SMC Pentax 67 AERO 1:4 200mm

There is an eBay auction (well, BIN for $6,880) for a lens I have never seen before and may never see again. According to the seller it was custom made for the Japanese Defence forces and is a high definition fixed focus lens meant for aerophotography. Going by the pictures the story seems plausible; it has an entirely new barrel with no focusing mechanism rather than just the usual one with a set screw to lock it off and the engraving around the barrel looks to be correct too. Although the dealer freely admits that he can't verify the information, he sells a lot of used Pentax gear and seems fairly knowledgeable when it comes to the 6x7 range.

220413 has now passed into my hands (via eBay) and sits in the cabinet with the japanese KM, K2 and 6x7 demonstrators, transparent Auto 110 and SF1 and SF7, and dummy K30 and KS-1 and RS1000. I think that just about covers all of the styles of Pentax demonstration units.

Oh, I think there was a transparent K-20D on eBay recently with a very high price tag. I'm happy just having some of each type rather than chasing every different example.

Why do I collect film cameras from Asahi Opt Co?

The multi exposure mod is the only one that I am certain is factory designed as I have the service instructions for carrying out the mod. Other things I have seen that might be factory approved include the mechanical Bulb mod (to the mirror rest button) and the 6x7 version of the 500/4.5. And then there is this, which I assume is a MLU retrofit given its location on the body. It looks aftermarket but I have seen another one the same, so maybe it is a factory mod.

I collect the 6x7 system. Back in the film era it was the system I aspired to, but could never afford. Once the digital era took over and secondhand prices went into freefall I picked up a body and a few lenses to shoot with and found I really liked it. When I went looking for more information I found that really, there is nothing out there other than the catalogs. I ended up getting a little obsessed with researching the system which in turn lead to me collecting most of the system simply to know what is out there. Even then there are items that don't appear in any catalogs (like the SMCT version of the 500/5.6) and things that are in the catalogs that don't appear to have been manufactured (the Super-Macro-Takumar version of the 135/4). I still don't know how many cameras were made (around 220,000 6x7/67 and an unknown number of 67II) and every so often something new will appear to change what I thought I knew.

A good example is the film type select, a familiar switch that says 120/220 or 10/21 in green and yellow paint. Except that the first bodies had a different switch and the paint was white, and then for a while the paint was yellow and blue (like the feet/meters marking on lenses) before changing to yellow and green. I have no idea why it changed.

Just a heads up, there is an Asahiflex 500/5 on eBay at the moment, although given the price (1499 euros) I'm not sure anyone will be rushing to buy it. Anyway it is later than mine (mine is serial 59462, this one is 96047) but also has a slightly different tripod mount and a metric scale compared to the imperial scale on mine. It is being sold in Austria, so maybe the metric scale is simply a regional difference.

Auto 110 with modern film?
Posted By Paul Ewins
Replies: 15

My own experiences of reloading 16mm film into 110 cartridges was mixed. I carefully cut the cartridge apart along the seams and once reloaded stuck it back together with black tape. It worked, in as far as there were no light leaks and the film moved through the cartridge correctly. Frame spacing was hit and miss because the film didn't have the end of frame perforations in the correct spot, so I was just judging it based on the backing paper. Fortunately the shutter cocking of the Auto 110 doesn't rely on the perforations like some 110 cameras. Two strokes of the advance lever and it is cocked, but if you wind on again the shutter is uncocked. It should be entirely feasible to split film down to the correct width and load it into 110 cartridges.

Pentax 67 (not 6x7) with no MLU

This is an older 6x7 body that has had it's winder repaired using the assembly from a 67. You will see all sorts of variations as repairers fix cameras with the parts that are available and in some cases upgrade older cameras with features from newer bodies.

Generally speaking, the serial number is the most reliable way of telling which body you have. The non MLU went from 4000000 to around 4060700, the MLU went to around 4159850 and then the 67 went from there to about 4220000.

A couple of Takumars, but not on Pentax cameras. Takumar 75/3.5 on Press Van strut folder and T-Takumar 75/3.5 on Minesix drop bed folder. Both cameras use 120 film, but the Press Van also had the option of 35mm with special reels (sadly missing on my camera) while the Minesix gave you the option of 6x4.5 or 6x6.

I guess that is a step up from a counterfeit K1000, although the counterfeit K1000 is a lot more convincing.

Is there a spherical bulge on the focussing screen? There is a special variant of the basic Pentax ME/MG called the MF that was used with endoscopes and the like and that has this type of screen. Apparently there was also an MX version (MX medical) although it may not be anything more than a special focussing screen. There a a couple shown here, but it is hard to tell if there is anything different to a regular MX.

Flash manual as requested. I also realised I hadn't shown the little tin that holds the sync cable. Not sure why they thought the cable needed its own container but it's a nice touch. Note that there was apparently a whole research section devoted to flash guns.
