Hey, I wasn't actually SERIOUS.

-just very, very surprised, and rather perplexed.

Try manually focussing WHILE holding the preview button in, then get back to me.

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.

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.

I'll give it a go tomorrow.

Thanks for the idea.

The new 21 Distagon has just been announced on the Zeiss website. I wonder how it compares vs the old one.

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?

I'm wondering if the extra diameter is to lessen vignetting.

Does the CZ show much vignetting, wide open, on FF?

BTW, mrawz,

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.

But heck, it's actually not bad!

Nice serial number

Not in ZE mount yet but getting close.

It would be impossible for them not to have auto-aperture if they are to comply with the EF mount spec.

Am I the only one who finds this obvious?

Nah, i'm surprised to see this much triple checking.

Side note, who is selling their CZ 21/2.8 for $700 now?

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!

Same, a couple Zeiss zooms for EF mount and I'd be happy as a pig in... well, you know.

17-35/2.8 and 24-70/2.8 would solve my "lens dilemna" for good. Electronic aperture, just like the ZE lenses, and manual focus would be just fine. This would be a spectacular combination that I would buy into immediately and never look back.

This recalls my previous question, which was: is the Zeiss/Sony deal for zoom lenses an exclusive arrangement, or is Zeiss free to create zooms for other mounts as they see fit?

Good question. I'd imagine that the Zeiss/Sony deal is more about autofocus, rather than zooms, but I don't know. I sure wish some of those sweet ZE/ZF manual lenses came in Sony mount, although I'm sure Sony wouldn't allow that.

Didn't know that the ZE lenses will use "a slightly different optical formula" than ZF versions, but that's what DFarkas says in his "Day 3" photokina post:

"The styling is quite attractive on the ZE lenses. More tapered and rounded than the ZFs. Also learned they are slightly different optical formulas. The low pass filters used in Canons are quite different than those in Nikons, so the lens design had to be modified to properly focus on the Canon sensor. These two lenses will be available starting in November, then Zeiss will continue to roll out the rest of the lens line by early Spring 2009, matching the full offerings of the ZFs."

That would mean ZE lenses could perform a bit better on Canon bodies than ZF lenses do? Seems strange.

In addition to the different low pass filters, given the different lens mount register, I suspect that slightly different optical formulas are needed to optimize performance for the different mounts.

This Farkas guy doesn't seem to know what he's talking about. I understand that the optical formula needs to be slightly modified to account for the difference in register and the lens will definitely perform better than with an adapter. But what the heck the low pass filter has to do in the lens design? Canon have changed their low pass filters practically with every new model. Some with strong AA filters, others with very weak almost non existent ones. Did they make special glass for each camera model?

Specifically, anything that has a floating element design (CRC).

I wonder if the new ZE lenses will have compatibility issues with new Canon bodies .... as Sigma lenses do. Do you think ZE lenses may require re-chipping to make it work with future Canon bodies?

I was wondering about the same. But it should be unlikely as the only communication required is to close down the aperture, unlike the Sigma's mostly AF problems.
