Like... which ones?
The Pentax 6x7. world's first 6x7 SLR with electronic shutter and TTL metering plus (at the time) the most extensive lens system for a 6x7 SLR?
The Electro-Spotmatic, first SLR with electronic auto exposure?
The Pentax ME-F,, first autofocus SLR?
The first series of fully...
The NT backs are reported to be much more problematic, reliability-wise.
As for the P6 mount, yes it's good if you have Pentacon Six lenses, but there are very good lenses on the regular Salyut/K88 mount, use a Vega 90/2.8 or an Arsat 80/2.8 and you won't miss the Biometar too much.
It does have coating at all surfaces. Single-coated Tessar lenses are supposed to be contrasty. There are only three optical groups there (!)
Something must be wrong with your lens or camera. For example, a plethora of tiny micro-scratches at the front surface can wipe off contrast. Same with...
Looking at the size of that 200, i don't think the wide open performance at the corners would be as good as a real 6x6 200/4mm lens.
I have a 200/4.5 lens for the Bronica ETR system (6x4.5 format, smaller than 6x6). This is a lens for a smaller format and slower, yet it's bigger than the 200/4...
Pentax (Ricoh) posted a video yesterday:
The mechanism shown on the video is the film advance lever, counter, and bottom mechanism found in the Pentax P30. Moreover the rewind knob is exactly as in the P30/P50 models.
This means the forthcoming camera will use a vertical shutter, just like...
69 is a naughty number.
I'm a happy 6x4.5 user (SEE MY AVATAR...) but still I like 6x7. I agree with your opinion on 6x4.5.
For me 6x7 is a more manageable alternative to 4x5; while 6x4.5 is a better quality alternative to 35mm.
Congratulations! The camera won't operate properly without film. The film, when moving, moves the sprockets which then liberate the shutter release.
Probably your lens needs cleaning.
Most likely the rangeifinder. Every time you disassemble the lens (for cleaning), the rangefinder-lens...
As a P67 user... i'd also wish for 100% coverage, and a better mirror dampening system. More leaf-shutter lenses too. Try to make a 105/2.0 so we can drool.
I want it to cost $99. Thanks Ricoh for listening.
According to whom? According to Purple Tentacle?
Among camera collectors, the popularity of the Pentax 6x7 is on the rise. Pentax produced the 6x7 camera from 1969 to 1975, then improved it on 1976, kept producing it until ca. 1989, then revamped it as the Pentax 67, then in 1998 they released...
These things can often be removed using mouse pads. Get a mouse pad, the kind that have a thick rubber base with a sticky material at the bottom. Use the sticky rubber to press against the top of the beauty plate. Works very well in many cameras.
I never said you need to be apprenticed to Nikon.
Glad you recognize the need for custom tools. Of course you need to make them. This underlines my point -- this is something that needs dedication and commitment.
mikeno62 is great.
If you're fitting such a luxury, famous, high-performance, zeiss-pounding lens such as a KODAK EKTAR, make sure to calibrate the focusing screen height to the particular back you're going to use.
The "Kiev survival site" has documentation on how to disassemble the back. If you don't find it...
Leitz? This is the first time I hear the mention of Leitz having manufactured a medium format lens.
As far as I know Leitz only manufactured amateur-format lenses.
Dear Cholentpot,
Let me give my opinion as a camera tech.
When you have a failure caused by lack of lubrication and cleaning, which is pretty common, it's not only one part of the mechanism the one that needs to be "unstuck", but the whole camera needs to be cleaned and re-lubed because, even...
If the film advances but the camera doesn't fire, a possibility is that the mirror mechanism is stuck. When pressing the shutter button, the mirror mechanism should fire the mirror, which in turn fires the shutter mechanism.
The camera needs a stripdown so the mirror box is accessed , the...
Any RF camera without a combined RF/VF has a serious ergonomic hindrance.
A rolleicord Vb, simplistic as it might appear, is not such a simple camera, because it has a leaf shutter inside.
If the question is "best medium format camera ever designed", my vote goes to the Mamiya RB67 (later...
The haze is most likely on the cemented element. This is typical of many lenses.
For example the Pentax-M and Pentax -A 50/1.4 lenses suffer of the same problem, also at the rearmost back group. As well as the famous Super-Multi-Coated Takumar 6x7 105/2.4; many many of them suffer from haze...
A technician can replace the focusing helical grease for a stiffer one.
But to tape the barrel with electrician tape sounds, to me, a more practical proposition...
But... do you have a Pentax LX?
My current MF gear:
