Re: New Carl Zeiss lenses for Pentax K mount!

Adam,

big hit in Nikon-land, that's only because the Nikon 50/1.4 is fairly 
average in performance not because the Zeiss is legendary in its 
performance.

especially when it's Cosina Zeiss...

 Yet several of the Cosina-built Zeiss lenses outperform their Contax 
 predecessors. Notably the ZF 25/2.8(which is an entirely new design) and 
 the ZM 21/2.8.

don't get me wrong, I have nothing against Cosina. Actually they are 
quite like Pentax and usually offer excellent value for money. But these 
Carl Zeiss lenses are far from that - Pentax own Limiteds are much 
better value IMO.

BTW Contax(Kyocera)/Cosina doesn't matter, both are building lenses in 
some automated factory so I'd expect similar results. The price of 
original Zeiss/Leica glass is higher because of the labour cost involved 
(hand assembly, testing), while this is perhaps slightly above standard 
mass production with fancy name on top of it (an unnecessarily high 
price IMHO).

Cheers,

Peter

I have 3 Cosina Voightlander lenses in PKA, and their
build and optical quality is no worse than that of Pentax LTDs in every respect.
They are quite costly too.

Pentax LTD's are an incredible value, costing significantly less than 
any other lenses of equivalent quality other than the Voightlanders and 
some Nikkor AI-S's. Price against L glass sometime and look how 
incredible the LTD's value is.

The Carl Zeiss lenses from Cosina  Zeiss are actually a decent value 
compared to what their Contax predecessors and Leica competition. Note 
the current Zeiss lenses are individually QC'd by Zeiss on Zeiss test 
kit located in the Cosina factory in Japan. They're also one of the very 
few lens lines produced entirely in Japan or Germany (Cosina is the only 
Japanese lens manufacturer to produce all of its lenses in Japan, Zeiss 
makes a couple of the ZM line in Germany as Cosina isn't setup to handle 
floating elements). Even Leica can't say that (Leica only does finishing 
and QC in Germany, base production is elsewhere, IIRC it's Portugal).

Here's the ZF 25/2.8 vs. the Canon 24/1.4L (the winner of their 24mm roundup,

I can answer that without even thinking: no.

The Pentax-A 24/2.8 is a very good lens. The Zeiss is without a doubt  
better, but as in the evaluation of high end stereo, how much better  
and whether it has any practical significance is questionable. A  
greater difference in quality would be seen by putting the camera on  
a tripod vs working hand held.

I've seen this time and time again. Once you're at the quality level  
of a lens like the A24/2.8, the improvement lent by a better lens is  
pretty difficult to see.

These lenses are wonderful performers in Nikon mount and should be  
equally wonderful in Pentax mount.

The only downside is that it would be very nice indeed to see them  
support the Pentax KA mount rather than just the K mount  
specification. That would lend much more functionality to the Pentax  
DSLRs metering operations.

Which is good news. An actually available 85/1.4 (although one that is 
inferior to the Pentax SMC-A version), a couple of superb macros, a 35/2 
, a 50 that's not really worth bothering with (While the 50 has been a

I think it was 16-9.net that posted a comparison of fast 85's. The SMC-A 
and Canon f1.2L essentially tied for 1st place. The Zeiss comes in 
behind the Nikkor AI-S (and therefore behind the Nikkor AF-D which 
outperforms the AI-S version). Essentially it's a very good lens that 
happens to be the worst of the current lot.

At the very least I can see the CZ 50/2 macro replacing a handful of
my Pentax 50mm lenses, so it shouldn't cost too much in the end.

 Which is good news. An actually available 85/1.4 (although one that is
 inferior to the Pentax SMC-A version), a couple of superb macros, a 35/2
 , a 50 that's not really worth bothering with (While the 50 has been a
 big hit in Nikon-land, that's only because the Nikon 50/1.4 is fairly
 average in performance not because the Zeiss is legendary in its
 performance. I'd rather a Pentax 50/1.4 than the Zeiss) and a superb
 25/2.8 (which is really the gem of the current Zeiss line of 35mm SLR
 lenses).
 
 At the very least I can see the CZ 50/2 macro replacing a handful of
 my Pentax 50mm lenses, so it shouldn't cost too much in the end.
 

For me, the most interesting is the 25/2.8(in ZF form though). But 
that's a bread  butter focal length for me. The 50/2 does look 
interesting as a replacement for a few 50's, but I need speed more than 
the macro capability at that length.

 Regards,

Or the Zeiss 25mm f/2.8 vs. Pentax SMCP-A 24mm f/2.8?

Having had the Pentax-A lens, and based on the stuff I've seen with  
the Zeiss, I'd take the Zeiss.

Besides, you can't buy an SMC Pentax-A 24mm f/2.8 new anywhere that I  
know of.

The testing I've seen on the Zeiss indicates it's notably better in 
performance than the Nikkor 24/2.8 AI-S. I've not owned the Pentax (it's 
lack of availability was one reason I went back to Nikon kit as my 
primary choice) but the test shots I've seen indicate it's maybe a match 
for the Nikkor but not for the Zeiss.
