Hi All,

Please suggest a fast normal (around 50 mm) lens with a sonnar design
Something like 50 1.4

The smaller the better. If possible not too overpriced.
It will go for he NEX so mount is not really important.

BR,
Stefan

Cheap (relatively), Jupiter-3 1.5/50, Contax/Kiev or Leica TM mount:



A bit more expensive, Zeiss Sonnar 1.5/50, Contax/Kiev mount :



Much more expensive and new, C-Sonnar 1.5/50 ZM, Leica M bayonet:

Try a KMZ Jupiter-3 50/1.5 but I don't know if it's small enough for you. From the chart on this page that looks like your most affordable option. Good luck!

J-3 it will be i guess. Smile

I was wondering if there is something for SLR's made in Japan after the war?

50 mm Nikkor with sonnar scheme?

Nikon built their own 50/1.5 Sonnar derived lens after WWII, when the Zeiss patents were public domained. But within a year or two they upgraded to the famous 50/1.4 that was double Gauss derived - thanks to its relative rarity, the 50/1.5 is a collectors item and more expensive than the 50/1.4, even though the latter is optically superior (and generally considered the best lens in its time).

There is the very rare Takumar 58mm
Almost impossible to find.
Reflex cameras boomed after the war in a time when lens coating was already established.
So all manufacturers did create fast 50mm with double Gauss scheme (Planar) which is faster and sharper wide open than Sonnar.
Sonnar remained as short/medium tele option.

Bzzt, wrong! Reading up the Nikon history site over the lunch break, that one was a seven lens Sonnar as well.

I've came across this link :

At the bottom you can find:
Sonnar (7 elements)
Nikkor-S 50/1.4

This is RF lens or SLR one?

Stefan

RF - their Sonnars were from the early fifties. They had already made the transition to Gauss type normals before they released the F.
