I bought a Pancolar 50mm yesterday, but I would also really love to have a planar 50mm in my collection. Anything I should look out for and what is a fear price to pay?!?

There are two models, the f/1.7 and the f/1.4, and each of these is available in AE and MM configurations. The MM is newer, and allows Program and Shutter Priority modes in addition to Aperture Priority mode of the AE. Some say that some of the Contax lenses in MM have a redesigned optical configuration, but I have both the AE and MM Planar 1.7/50 and I can't tell any difference. The AE is generally slightly cheaper than the MM version. If you're not mounting it on a Contax MM-enabled body, then there's no reason to pass up an attractively priced AE model to wait for the MM version.

The f/1.7 version is very slightly sharper then the f/1.4 (though the difference is indistinguishable from trivial), in my experience, at or near wide bore, but stopped down, nothing to choose. My personal favourite is the 1.4/50.

Prices are hard to advise on, since there can be considerable variations, and that's without taking into account different price averages in different countries. I've seen the 1.7/50 AE for less than £50 (GBP), though more usually £75-£90 , and the 1.4/50 AE for between £120 and £150. One respected dealer in the UK has a 1.7/50 MM for £200 which I think is considerably overpriced.

ebay prices of last months:
50/1.4 150-200 euros (usually around 200)
50/1.7 110-150 euros

The 50/1.4 has a different, more vivid color rendering. I've heard this from several different sources.

MM version might be required if you are going to mount on a Nikon with the leitax conversion. Otherwise the AE is just as good optically but has the ninja star bokeh. Those prices seem about right though.

Hi, wasn't the 1.4 the "sharpest lens ever"? I thought it was a bit sharper than the 1.7, while both stopped down, but i have none of'em.

It's the other way round, 1.7 sharper than 1.4 at equivalent F stop. But then, the contax G 45/2 is sharper at F4 than 50/1.7 at F5.6 (check the MTF at Zeiss), and then Summicron is sharper at F2 than 45/2 at F2, so there goes the "sharpest lens ever".

Practically, I cannot discern the three Zeiss lens' difference in sharpness, they are all sharper than my skill.

Summicron R or Summicron M?

M, I don't own either of the Summicron though so this is from photodo. Trying to convince myself that 45/2 is all I need Laughing

Hi,

I have both the 1.7 and 1.4 and stopped down it is almost impossible to distinguish them. The 1.4 is slightly bulkier, but nothing to worry about if you are used to carrying L-glass around... Smile

The one that always carry with me is the 1.4, it has given me so many nice pictures. At f/1.4 it has a nice glow and stopped down it rips your eyes with its sharpness and popping colours. Skin tones are rendered beautifully, like this boy I did in a photo shoot last year:



One that may rival it for portraits is the Helios 44M-6. Not necessarily its sharpness (even though it is very good), but due to its rendering of skin details and hair structure. After taking pictures with it I always regret not taking it with me more often.
