I think reliably transferring lens data to the camera so all modes are available is a development don't you? I have some Contax Zeiss glass but I'm not using it on my EOS bodies yet. Is there an adapter that will work without stop-down metering?
It seems to me that is a development, plus the focus confirm.
I've had a handful of Contax Zeiss, and they've all worked on all of my EF bodies, with focus confirm, with the right adapter. And when I'm focusing manually I'm usually using Live View, so "stop down" metering isn't necessary. Yes, the new Z models will be nice, but they'll also be outrageously priced compared to their "old school" counterparts. I wouldn't be able to justify the premium... Now if they performed AF, that would be something to talk about!

OBERKOCHEN/Germany, Carl Zeiss is expanding its successful line of SLR lenses: ZE lenses with EF bayonet for all analog and digital EOS camera models. As with all EF lenses, the new ZE lenses from Carl Zeiss transfer all information exclusively via electronic contacts. This means that all exposure modes such as programmed auto exposure, shutter priority, aperture priority and manual setting are supported.
The camera’s automatic focus confirmation also remains available to an unlimited extent with these manual focus lenses. With digital SLRs, the lens data and all exposure data can also be accessed via the camera’s EXIF file. Even E-TTL flash metering is supported. The first lenses to be available will be the Planar T* 1.4/50 ZE and the Planar T* 1.4/85 ZE in the last quarter of this year.
Further focal lengths will be added to the line within the next few months.
Ok, help me out. What does stop down metering have to do with live view? I don't use live view. I'm not going to be using live view for the shooting I do - I need to look through the viewfinder. I'm not concerned about depth of field preview.
I'm talking about using AV and TV mode, for example. Won't the electronics in these ZEs aid that? Or do the adapters already do that by transferring shutter speed/aperture information back to the body?
Wow, the legendary 21mm Distagon in an EF mount! Such a lens would see very limited use from me, but it still gets the blood going. Canon needs to buy out CZ and make an AF version
Boy, if Canon comes out with a 24/1.4L Mk II and Zeiss releases the ZE/EOS 21/2.8 Distagon .... deciding which lens to get is going to be a real problem! I am sure price-wise they will be about the same. If the 24L Mk II is at least as good as the 35L it will make my decision that much easier .... I will pick the f1.4 with AF over the f2.8 with MF, of course!

Stop down metering is a method for being able to focus with the lens wide open (to let in the most light so you can see better), then stopping down to the desired aperture to take the photo. Live View has 2 modes, on that simulates exposure (you may need to use stop down metering with this mode), and another mode which automatically brightens the image to aid in focusing. Therefore stop-down metering becomes unnecessary.
Of course if you don't use live view then this won't do you any good. But live view, with it's 5x and 10x magnification for critical focus, is the best thing to ever happen to manually focused lenses.

You are correct. This is an advancement over using the older lenses with an adapter.
The new lenses will work identically to your EF lenses when you shut the AF switch to the off position.
This is much different than the experience of shooting the old lenses mounted with an adapter, using Av mode plus stop-down metering. AF-confirm chips sort of help here, but they do not allow the camera to record the shooting aperture or enable accurate E-TTL metering, or auto-aperture, of course.
Is this enough for people like ChrisDM to switch? Maybe not, because stop-down metering suits his type of photography with those particular lenses.
I too use tons of lenses with adapters (or converted mounts) in full-manual-everything mode. I don't even bother with the AF confirm chips. I get great results, but I certainly would choose to have auto-aperture (and all the corresponding exposure modes) full EXIF, and E-TTL on all those lenses if I had the choice. I have one such lens; the Voigtlander 125/2.5 Macro APO-Lanthar in native EOS mount. It is a joy to use, incredible really, and I fully expect that Cosina will be making the ZEs at least as good as this.

Hmmmm... a re-introduction of the 21mm distagon at a reasonable price I'd buy one (assuming performance is the same as the original).
If you think the 21mm Distagon Is overpriced, Have you seen the new Leica Noctilux M 50 mm f/0.95 ASPH That was announced today? It's a bargain at £6290!!

The new one is a different design from the "legendary" one. However, we can hope it retains the "legendary" performance
