Can I use my 67 lenses on the new 645D 2014?

I have six primes (trending toward a seventh) for my 67ii. As I contemplate a move this year to digital SLR I consider IQ the prime factor in my deliberations. If I go D800E I also have to invest in five or six new lenses. If I can use what I have, I can put my dollars into a camera body, maybe the new 645D. So, the big question is, can I use my primes and get great IQ? What kind of adaptor do I have to use? What are the Pros and Cons of doing this?

If we're reasonably sure there's a full-frame DSLR coming in 2013, it's going to have to have some kind of a mount. The current K-mount lenses probably won't have a large enough image circle for 24x36, so this might necessitate either a new mount unique to Pentax or a some widely-used (in the industry) mount. There'll be some consideration to legacy lenses, I'm sure, but if the move is to higher performance, better-corrected lenses, there might be some "clean paper" thinking. This would be a good question for one of the upcoming interviews with Ricoh-Pentax insiders. They've undoubtedly reached conclusions on the mount issue.

What is the lens mount type a full frame Pentax will use? I'll lean toward Zeiss primes until Pentax fills in the gaps.

After 14 years toting a 67ii body (or two), four or five 67 lenses, a 6' Gitzo tripod and Bogen 3047 head in the Rockies, most of the current FF digitals seem nearly petite by comparison. I certainly want a better hand grip than a D600, and more space for (larger) buttons that don't require a stylus to operate. I suspect Pentax will bring out an efficient but SUFficient design.

Some good points, MFP. I've done 67 and 67ii for going on 14 years and I know I'll be "adapting" some kind of full frame system. I would expect Zeiss would have some lenses I'd like, but I might have to mix in a couple of Sigma's better pieces at their more favorable price levels. I wouldn't expect Pentax to try and out-do Nikon's D4 (or successor), but thought it would make sense to land somewhere between the D600 and D800 twins. I figured Pentax would do that and come in 10-15% lower in retail price.

Okay, I'll give up the articulating screen for excellent weather sealing.

Hello, everyone. It's likely Pentax will introduce a full-frame (24x36) DSLR sometime in 2013. I'll start this new thread with my wish. I'd like "it" to have two models. One would be a great STILL camera, possessing a state of the art sensor offering from 24 to 36 megapixels resolution, good live view, an articulating display, strong low-noise ISO to 6,400, efficient autofocus, a modest frame rate, limited and intuitive menus, and additions to the lens round-up featuring fine glass in focal lengths from 21, 35, 50, 85, 105, 135 to 150 over the next 18 months. Priced under $2,150. The OTHER MODEL would be essentially the same, but would include video. Priced under $2,950. Maybe call the first the KF-S (for still) and the other, the KF-SV (for video). What do you think?.

If what you speculate comes true, Mr. Hurst, the Pentax will be a strong player in the MFD field, especially at its current price level. For a while now, I'm going to concentrate on using a formidible FILM camera the next several months -- my 67ii. Thanks, Ed, for your timely and thoughtful input about the conversion to digital and those intriguing possibilities.

Okay, I think I've got a pretty good feel for the lens issues. NOW, I'm hearing there's a new successor body in the pipeline. Is this imminent? Will there be some special attributes that make waiting (a couple of months? six?) a good idea? I have enough film to carry over to January.

Thanks, Surfotog. That .8 idea was the kind of thing I was looking for.

Sorry, Ed. With all the postings on all the blogs, along with the various reviews and advertisements, I've tried to "get with it" and am adopting some of the shorthand. The "FX" I mentioned refers to any of the sensors that generally replicate the dimensions of a frame of 35mm film, ie, 24mm x 36mm. (Countering that, "DX" refers to the smaller APS-c sensors that are about 40% of the full frame area. I should probably just do my research and start speaking in terms of Angle of View which is, after all, a clearer way of defining whether a lens is "wide," "normal" or some variant of "telephoto."

Because I spent several decades with 35mm SLRs, I can visualize the general effect of a 25mm lens compared with a 35mm, or 85mm, etc. So, it sounds like my 55mm from the 67 system might make an image through the 645D about like a 35 or 45mm lens on a Canikon DSLR. Huh?

Okay, mentors: I appreciate the assessment. Meanwhile, I'll toss a math question both of you have probably already worked out during your own transitions. What FX equivalency do I have, lens by lens, if I use my current 67 glass on the 645D system? My kit contains the 45, 55, 90, 135 and 200 (plus the 300). I know if I did a "conversion" from 67 down to FX those focal lengths would essentially be halved. What happens going just down to 645? Thanks.

Ed, focusing my 300 extends the barrel length. LJ

Okay, Ed. Thanks for the detailed reply. This raises another question. I know the lens mounts (67 and 645) are not the same dimensions, so that means there'll be a step-down adapter. How does this work for the auto diaphragm function -- focusing and composing wide open, then stopping down at the instant of exposure? So far, this all sounds encouraging. If my current lenses will give me really good results this might be a better path to follow than shopping a D800E and 3-5 Zeiss lenses, in pursuit of MF image quality.

Hello, Forum readers: I have a six lens kit with my 67ii body. I'm working through my last nine ProPack boxes of Provia this season and am looking ahead to a transition to digital capture. A big question for me is, how viable are my lenses if I decide to go to the 645D? I have the 45, 55, 90, 135, 200 and 300 late model lenses. Which, if any, would pair up with the 645D body and produce high quality results? I understand the focal lengths I mentioned will have different "effective" focal lengths or equivalencies with the sensor. Also, I know I'd be focusing manually, but I'm not clear on how the exposure readings will work out. Do any of you want to clarify (or discourage me) about planning on using my existing lenses? Thanks for the input. I'm looking forward to learning a lot from this community.
