Leitz and Leica Noctilux the same?

[karl_yik1]

Hello all,

Can someone tell me if the glass used in a Leitz Noct with detachable

hood and that of the current noct are the same. Ive read somewhere

that the coating may be improved in the latter version.??

Many thanks

I believe that they are the same. I have the detachable hood version. It takes 59mm filters, which is an annoyance to me, since I have to have a completely different set of filters from the 60mm ones I use with my 75mm lux. More stuff to carry. The detachable hood has slits in it for less obstruction of the viewfinder, which the slide-out hood does not, but the convenience factor of the slide-out hood is a consideration. In the newer slide-out version the lens takes 60mm filters. The detachable hood is round, and the attached hood is squar-ish shaped, like the 35mm cron hood. You may have the glass confused with the older f1.2 nocti, which is a different lens altogether, and according to reports, not nearly as sharp as the f1.0.

The 1st Noctilux takes 58mm filters, not 59mm. You can get a 60-58 step-down ring for the 75, which will let you use the much more common 58mm (most of Canon's lenses use them)on both lenses.

Coating Schmoating

 

The physics of the wavelengths of radiation have been known for a long time, quit worrying.

 

Where's Phill???

So Karl, are you looking for different glass or better coating?

 

I always recommend the book Identifying Leica Lenses to those who like to know about different versions/optical constructions, even though it does not mention the exact glass types used for each element.

 

You could also try Puts' longish PDF on lenses from the Leica web site.
