Right now, I think there are two very high performance, very fast 35s, but both have drawbacks - the Nokton is huge, and Summilux ASPH is out of most people's price range. I think there's a market for a compromise between those two, whether it's Zeiss or CV - I have a CV 1.2 now, but I'd be happy to pay a little more to trade the extra half stop of light for smaller size (but the same characteristics otherwise).

Exactly my point

i think this guy never heard of the nokton 1.4? you are not even trading an extra half stop and its a much more sharper lens than the cv 1.2 at 1.4 then the nokton 1.4.... AND YOU ARE NOT EVEN TRADING HALF STOP

Sorry, but the 1.4 suffers from terrible focus shift, so it doesn't count

Dear Roger,

this is not the first time that you are referring to CV aspherical lenses having hybrid elements. Do you have any reference for this ?

Just wondering. Thanks,

Roland.

Dear Roland,

Phew! Not that I can easily find. Only an (increasingly unreliable) memory of what I as told or read when they came out. I can't think where I'd have got that impression if it were not true.

Ground aspherics are out on the basis of cost. Moulded glass aspherics would be possible (I'm pretty sure even Leica use them, but I'd need to check). Even so I'm reasonably confident I've remembered correctly that these are hybrid aspherics with the aspheric elements moulded onto glass elements. I think Voigtländer themselves would have pulled me up on this if I were wrong, but I'll check at photokina to see what they say.

Cheers,

R.

Please do. One of the aspheric CV lenses (12/5.6) has an exterior aspheric surface, which is why I always thought the CV aspheric elements were molded glass.

WoW! What a great News for our Rangefinder fans! I can't wait to see the newest ZM fast lenses release into the market. How I wish Zeiss could produce ZM 50mm f1.1, ZM 35mm f1.4 or even f1.2. : ) Hope my dream will be come true!
