p.2 #1 · What ONE lens would make you consider a platform change ???
I agree that the 28-85 is a great lens. I had one for a while and was one of the few standard zooms I actually liked. It's not fantastic at 28mm (but still good), but is VERY good from 35-85mm. Great color too, of course.

Why is that? I've seen claims that the CY version should top the 35/1.4 distagon series, ie over the ZE/ZFs etc (havent seen "proof" though). I thought the Rollei version the one with less good coating (HFT) and the triangular aperture/bokeh thing?
there have a number of comparisons in this forum and elsewhere. from reading them and looking at the pictures (i also own the c/y version), it seems to me the advantage of the c/y/rollei version over the new Z* is that it is noticeably smaller, has less veiling flare wide open, and better bokeh in the central portion of the image. the Z* is sharper at the edges, has smoother bokeh at the edges, less CA, better aperture blades for stopped down bokeh (though some people like triangles or octogons), on camera aperture control, and more modern coatings.
edit: i've not seen anything other than people who own the rollei on a low pixel density camera and have never shot with the Z* claiming the rollei is sharper. the mtfs suggest this is not the case.

how could you combine movements and rangefinder focusing?
With ground glass. Linhof have been doing it for a few decades - ever since the Technika III.
To clarify, you cannot see the effect of the tilt through the rangefinder, nor can you compose using the rangefinder on the Technikas, I would want a rangefinder with select-able framelines a-la leica M. That would allow hand-held shots, then just switch to the ground-glass if making use of tilt or shift.
... I just found a camera that does what I ask, only f/2.8 is the fastest glass.

All my zeiss ZE lenses keep me at the canon camp. I just don't feeling like taking the loss by switching to another platform.
I like them all but to pick one favorite: the 35/1.4 distagon ZE.

Not that I'm looking for such a camera, but you've piqued my curiosity. Which one, Dan?
Also, would it be impossible to combine movements with RF focusing? RF coupling for focusing is all mechanical now. While it might not be pretty, it seems like it would be possible to get the RF to mirror the T/S movements with coupling if the top portion of the camera were geared to mirror the lens' movements.

Sounds like a Rube Goldberg assignment ! Good luck with this.

Yes. I think I'll sacrifice an M9 for the sake of questionable progress. I'm not entirely sure how to control the light leaks yet, but I'm thinking some combination of duct tape and a plastic garbage bag.

are you thinking of having multiple rangefinder patches in different spots or measuring you subject size and angle in advance?

Not practical with roll film and or large format sheets ... but why not with a sensor ... micro-adjust to the nth degree.
That is a very clever idea Kent, with enough room tilt and shift would be possible. Given mirrorless/liveview advances over the past few years I'm surprised no one has thought of it... or have they?
You could add in lens profile corrections depending on degree of shift a-la lcc+M9.

I'll tell you as soon as I have bought one.

It is impossible to combine these because the effect of tilt/swing is wholly dependent on angle of incidence, focal length, DOF and covering power of the lens - it is too complex.

Fair enough.

Sure, sure. And they told Columbus he couldn't reach Asia by sailing west from Europe.

You could also design a curved sensor adjustment for COF and poor edge/corner performance / vignetting would be a thing of the past, enabling much simpler lens designs.
Maybe my great, great, great, great grandkids will see it happen.

Wfrank and jman,
Part of the appeal of the 35-70/3.4 is that it's so darn small and lightweight -- in comparison to modern f/2.8 zoom lenses. But I really prefer two-ring zoom ergonomics to the one-touch, particularly for tripod-based landscape work. Since more and more landscape photographers are working with live-view for critical focus, I think a two-touch 28-85 f/4 with fantastic sharpness across the frame, superb micro-contrast, and Zeiss colors (that is to say color separation), would sell pretty well. I'm probably dreaming on that one, though.

Lens? There ain't one. Thanks to Samyang there's no current system that I'd be interested in that is really lacking in lens lineup (Samyang has thankfully removed the lack of fast K mount glass which was half the reason I left K mount in the first place).
What could drive a platform change? Compact FF body with a good EVF for under $4000. Ideally similar in size to an FM2n, but realistically anywhere in the range from a NEX-7 to a K-5 would do it for me. Oh, and it can't be a Canon, I just don't get along with them.
I'd prefer it be a Nikon in fact, so I could settle on a single mount for film & digital (Not giving up my FM's).
Why couldn't we just turn all glass into tilt-capable by building enough room in the camera for a tilt-sensor?
