Leica summicron 90/f2 converted or Carl Zeiss ZK 85/1.4??

Hello guys,

I'm just a newbie in the pentaxforums !! I've been shooting Nikon for about 3 ½ years before making the switch (can't resist those limited though )

Right now, I'm having a dilemma to choose between Leica Summicron 90 f2 (3-cam) or CZ Planar T* 85 1.4 (new version)
Lucky enough, I was offered both at almost the same price (~500 EUR)...
Leica comes with box and everything, plus a R->PK mount converter, while CZ is just a lens + caps...

I'm more on the Leica side now (can't resist the name... hahah), but if someone who has experienced with both lens can share some insight, I would be very grateful. So, here is the questions.

1. Do using converter creates some problems ? Has anyone experienced it so far ?
2. Which one is easier to manual-focus ? I heard from my friends that Leica is very smooth and the travel distance is good enough. However, the brighter VF from 1.4 should be easier ?
3. The aperture ring... I heard that Leica feel abit 'click-clack' compare to CZ, is that true ?

Unfortunately, I have no chance to test both lens before I buy, as Leica of my friend reside in Hong Kong and while CZ is with the other in Thailand. Oh, and I will be using it with K-7...

I do not mentioned about pictures quality, as I think that CZ gives better overall sharpness, greater contrast, but I like the sharp center, and blur corner of Leica though...

Thanks in advance for all your answer !~

I would go with the Carl Zeiss hands down... renowned optical performance...f/1.4...
One of my friends modded his to PK mount.

Tossing out the f2 vs f1.4 comparison.


BUT you have to ask that the Leica adapter is the one which replaces the mount in the lens and not an add on adapter.
