I know another solution...
Buy a contax to leica adapter (just bought one from hong kong) they seem to work perfectly... then buy an opton sonnar 1,5, a 2 and even a zeiss tessar in contax mount...

This is what I want to do, but can't find the 1.5 anywhere :(
 
Yes, you can find 50/1.5 Sonnars made by Carl Zeiss Jena (pre-WWII & E. German post-WWII), Zeiss-Opton (immediate post-WWII W. German), & Carl Zeiss (post-WWII until demise of Contax RF line in 1961).

Oh.. I was thinking sonnar.. I want the 1.5 sonnar. Or is that the same thing?

Well, now there is no black one left at the good Mr. Gandy's shop (correction: Mr. Rose's). I hope I don't regret this, but I would like to have another fast M-mount lens besides my 35mm/1.4 Summilux ASPH. I think this Sonnar will be very different from my Planar too. I hope it will be good for subway shots and winter afternoons (the sun sets early in Boston in December and January). Can't wait for the packet!;)

Whoopsie, I meant Mr. Rose. I'm too tired to be reliable right now, and I'm doing this posting while making a peach-raspberry sauce for pancakes for breakfast tomorrow.

Tony,

Are they getting their own hood or will the 50/2 hood work on it?

The regular 35/50 hood does not fit the 50mm 1.5 and we will have the right hood avaialbe for $85.00 in a week.

The pancake topping was delicious:

2 Peaches, Pealed & Sliced
3/4 cup Raspberries (Frozen or Fresh)
4 Tablespoons Brown Sugar
1 Tablespoon Butter

Melt the butter in a heavy saucepan, then add the brown sugar and raspberries. Cook over medium heat about 5 min or until raspberries start to break down. Add the peach slices and cover with lid about 5 min. Stir occasionally. Remove lid and cook another 10 min. Cover and let sit overnight, or refrigerate. Warm up before using on pancakes or waffles.
 
mmm would be good on crepes, too. I used to make them for my last gf, fill them up with a little cottage cheese, sugar, roll 'em up, and eat with some strawberry or apricot jam. This sauce would be good, too.. thanks, to keep in mind for the next time I want to impress! :D
 
When can we see picture examples from this new Sonnar 50/1.5 lens?

Or is everyone just too busy making pancakes? ;)

Gentlemen,

Look closely at the lens diagram the lens itself is sitting on. That is NOT the Sonnar lens drawing... interesting.

Sounds a bit fishy to me.

The lens is standing on a system-leaflet that comes with all the ZM-lenses. Nothing fishy about it, I think. You will see different snips of the same leaflet in many of the auctions for ZM-lenses from this very same dealer.

I don't believe the new Sonnar is a true "Sonnar" if you compare lens diagrams. I believe the lens design is available at the Zeiss Web site, may be worth a look to confirm.

Can you define what is a 'true Sonnar design' in your view?

In general understanding, Sonnar is a more complex design implying more lens elements than a Tessar design. The more complex design was originally developed to achieve a more speedy lens, and the larger opening led to the need of better correction (therefore more elements).

Please forgive me, if this rudimentary understanding is too limited or ignorant to you guys.
 
Sonnar is a trademark owned by Zeiss AG, they use it how they want for any lens of some speed. A Sonnar type, as invented by Ludwig Bertele in the 1930's, ist a triplet-derivated (asymmetric) design consisting of 6 or 7 elements, 3 optical groups and having at least one cemented triplet.
In the 1950's some manufacturers like Canon and Pentax experimented to dissolve the rear-group of the Sonnar type, creating something in between Sonnar and Planar. In the 1960's Zeiss produced a set of f/2.8 telephotos with 4 or 5 elements, also calling them Sonnars.
The 2006 C-Sonnar is more a Sonnar than any other 50mm lens produced in the last 45 years, even if it has just 6 elements (3rd element cancelled) in 4 groups. The rest still looks like the 1932's Bertele design. It still has the cemented rear triplet

Well said. :)

Rover is correct that this is not an exact duplicate of the old Sonnars. Suffice it to say that this C-Sonnar is a "modern version" of the Sonnar design. It is asymmetrical & should give a different look than the Planar & other symmetrical designs - a look that will hopefully be very much like the original Sonnars. Needless to say, it is a design that we will never find in an SLR lens & one that makes the pursit of rangefinder photography worth the trouble.

So, take your pick - antique or modern - & have some fun with either. :cool:
