I'm with you on this one (which is why my mind boggles). I can certainly deal fairly well with stop-down metering, but I do not (in the least) see any advantage to it. Focusing stopped-down is something I only do between f2 and about f3.5, on very fast lenses. Beyond that, it is unreliable. I'd much rather focus wide open and have the camera stop-down to the preset aperture.
Agree. I have no trouble at all with stop-down metering and can do it very quickly now, but I'd still prefer not to do it. Also on my 5D and 1D II with large bright VF, I can reliably MF to f/5.6 in good light, but much prefer to focus wide open and all my lenses are f/1.4 or f/2 so are very bright.
Not having to worry about the quality of the adapter and whether I'll get infinity focus and having full exif, and focus confirm along with electronic aperture control are worth the price of updating alone IMO.
As for focus shift, from what I've read, there are very few lenses that have this problem. NONE of mine do, and I checked them all carefully. I really think you gys are desperately searching for reasons to discredit an idea you simply haven't tried.
Maybe not. I dunno, I don't care anymore.
Must get back to work so I can pay the rent, buy gas, eat, & other fun stuff.

Try manually focussing WHILE holding the preview button in, then get back to me.
Luddites!
PITA on the Canon's with the poor location, but I've done it plenty on Nikon and Pentax bodies where the DoF preview control is done by the right hand and focusing is the left hand.
Frankly, the ideal situation would be a DoF preview lock, like the push-on/push off AE-Lock that's common now. I do miss the ability to work either way that I have with my M645 and don't with my small-format bodies.

C'mon. Remember who you're talking to. This is the Alternative Forum. I'm sure most all of us have at one time or another experimented with various techniques to try to make using alternative lenses more convenient. I won't speak for others though I believe the sentiment is fairly universal, but one of the first (and easiest) decisions I made about using alternative lenses is that the lenses are easiest to focus wide open.
...if I manual focus with a lens stopped down anywhere from f8 and up; I'll tell you one thing, I'm not looking through the VF, I'm looking at the scale.
The only other situation that I can imagine doing that is when shooting macro, at which time it is simple enough to hit the DOF preview button, particularly if working from a tripod.
I'm all for a DOF preview lock, though, for those who would find it useful.

You know, I never actually tried that.Hmmmm......
It might be possible on the 5D to wrap my rt-hand around, then focus with my left hand ABOVE the lens. I only need the button down until I'm ready to press the shutter.
Zeiss will only make it better. I am seeing some people start to sell CY 21/2.8 now. By next year or so, old 21/2.8 will come back to its normal price. My friend used to pay 1K for a mint one many years ago.
Well, comparing the designs of the old Contax Zeiss 21mm and the new ZF/ZF/ZK 21mm you can see that they are very similar (see image below). Not identical, but we can certainly expect similar performance. The design has obviously been tweaked a bit, perhaps to compensate for glass types no longer available. But it is clear that Zeiss isn't messing with success. Given the obvious demand for the lens, one can only wonder what took them so long? http://boncratious.com/images/Zeiss-21mm-Distagons.jpg
I just tried that "rt-finger on the DOF button" idea. It actually is workable, although for only a few minutes at a time. I can't hold it like that forever.

Nah, i'm surprised to see this much triple checking.
Well, it caught me by surprise since Zeiss kept insisting right up to recently in "published" interviews there were "licensing issues". Obviously, they knew something more than what they were actually telling which, btw, makes this behavior kind of skeezy IMO. I realize the whole industry is rife with this kind of coyness in order to protect their existing products and sales. Someone believing themselves to be mature and wise in the ways of commerce will come along and say "well, that's business". They'll be right. It is also a skeezy way of doing business.

But what if there really were licensing issues and Zeiss simply worked those issues out or got around them? (After all, they said there were "issues," not "insurmountable issues.")
How is what Zeiss did different from if Leica had been asked about producing a medium-format camera a couple of months ago and had answered that there were "financial issues" with that, or if Canon had been asked a year ago about putting 1080 video in the next 5D and answering that there were "technical issues"? Someone who gave up on waiting for a Leica and bought a Hasselblad or someone who gave up on Canon and bought a prosumer videocam might be ticked that they didn't wait, but they can't really blame the company for not disclosing future products, it seems to me.
In a competitive market where every scoop is an advantage, no company will last long that tips its hand about future plans any more than it absolutely needs to. If I was developing any kind of product in that situation I'd make as little of it as possible until the product was fully ready to go to market.
I really want to see them come up with 17-35/2.8 for EF mount, hopely with same optics as the N lenses.
And if they can do that for $1200-$1300, I'll jump at it.
The N style lenses seem to be remade for the sony mount, not exact remakes of course but the genral zoom, focal lengths, autofocus, etc.
The manual contax lenses remade for the ef (and f, k, etc)mount, so i can't see them making anything autofocus for canon just yet..probaly be unlikely to even get a manual 35-70mm zoom to replace that contax lens!
