pete_kiefer Posted January 6, 2007 Share Posted January 6, 2007 I bought an old Pentax 6X7 (or 67) body to augment my 67II. (It was a lot cheaper than a film mag for an old Bronica.) The nomeclature on the face has been rubbed off from use. It has a mirror lock-up function, a safety release bitton and looks like a 67 in some other aspects, but I'd like to be sure. Anyone have a good way to tell. Link to comment Share on other sites More sharing options...
dougmiles Posted January 7, 2007 Share Posted January 7, 2007 As far as I know, the transition from 6x7 to 67 was just a name change in 1989, while small improvements continued to be made over the years. It might be possible to guess based on body serial number. I have a very late 6x7 with serial number 41806xx, so if yours has a lower number it's surely a 6x7 also. If the number is significantly higher it's probably a 67. My old non-MLU 6x7 has number 40563xx. I don't know what happened to serial numbers of the 67II but they are apparently not in the same sequence, as I've seen both 30685xx and 55445xx History time-line-- 1969 Pentax 6x7 non-MLU introduced 1976 Pentax 6x7 MLU -- Improvements (film-plane, mirror-mechanics, shutter material), and number of exposures from 220 reduced from 21 to 20. The Pentax 6x7 MLU with serial# starting with 415#### is technically equivalent to the 67 1989 Pentax 67 1998 Pentax 67II. Link to comment Share on other sites More sharing options...
steve_rasmussen Posted January 7, 2007 Share Posted January 7, 2007 Also, the Pentax 67 has a black casing around the shutter button, while the older 6x7 had a chrome casing. Link to comment Share on other sites More sharing options...
pete_kiefer Posted January 7, 2007 Author Share Posted January 7, 2007 Thanks All: It appears that it is a 67 from your input. The clincher was the black shutter release collar but the other info narrowed the options. Link to comment Share on other sites More sharing options...
george_stewart1 Posted January 8, 2007 Share Posted January 8, 2007 I have a 6x7 that I had modified (no-battery long exposure and mechanical mirror lockup) by Pentax. When returned, the new body plate indicated "67." Link to comment Share on other sites More sharing options...
dougmiles Posted January 9, 2007 Share Posted January 9, 2007 That's pretty cool, George! My later 6x7 has the multi-exposure control added, but it's still labeled "6x7". :) Link to comment Share on other sites More sharing options...
john_davey2 Posted January 12, 2007 Share Posted January 12, 2007 Oddly I just purchased a 6x7 that the seller posted as having a serial # of 6157xxx and it does not have MLU. Did all of the later numbers have MLU? I have not recieved it yet and knew from the pics he posted that it didn't but now amn wondering if something may be fishy.
