Hello all. Some of you may have read my previous thread asking about others experience with some of the various variety of 85/1.4 Planars.
http://forum.mflenses.com/lots-of-planar-85-1-4s-out-there-opinions-t25233.html
My point was that I'd noticed a difference between the ZK I had and the ZA I now have. I missed the 'dreamy' result of shooting the 6 element formula wide open vs the smooth and clear result from the newer 8 element calculation.
So, I went back a little further and sourced a Contax Planar (6 elements, very similar to the ZK - see no-X great post in the previous thread) and with the help of David Llato's (www.leitax.com) kit, I converted it to M42 and mounted it via a James Lao chipped M42-A mount adapter to my A900.
I was immediately returned to my expectations, but now that I had both lenses (for a while) I decided to do some quick tests to look closer in direct comparison.
The thrust here is bokeh. That was my whole reason for re-buying an older Planar when the new one was technically already so strong. Correspondingly, these images were taken to demonstrate to myself the differences between the two lenses while shooting the same scenes.
-------------------------------------------------------------------------------------
Shots were hand held and cross compared during the process to get good, similar samples. Shots are straight from the camera, taken RAW, no PP, other than to resize. In the end, I think it's possible to demonstrate the difference.
Contax on left, Sony on right.
Contax top, Sony bottom.
Dry facts -
ZA has distinct contrast and focal plane wide open.
CY has hazy, diffused appearance, overtaking plane of focus while wide open.
ZA has distinct green and red-violet fringe
CY has diffused purple fringe.
ZA circles of confusion tend to be evenly lit. Without lit borders, their overlapping goes largely un-noticed.
CY circles of confusion appear more strongly lit to their edges. Visible over-lapping.
Subjective take -
ZA has a bit more pop with stronger contrast on focus plane.
CY has a gentle, dreamy rendering of its subject
ZA CA's more apparent wide open as they are more concentrated and bright.
CY diffusion and base color of CA's renders them less obtrusive.
ZA indistinct circles overlap resulting a smooth, fluid out-of-focus (oof) appearance. Combined with strong focal plane contrast accentuates 'pop'.
CY mild Nisen (two-line) bokeh creates mild highlights which layer and appear more textured. Edge lighting plays off diffusion of lit areas to produce a 'dreamy' veil.
Note, after F2, the CY and ZA look much more similar and are both very sharp. But lenses are like people, seem conformed and well adjusted, but only when they open up are their true personalities known.
I wont comment to tell you which bokeh is better - to me it is an entirely subjective matter. I only present this to you for your own interest.
It seems in the end, one could own each Planar for various reasons, each is useful enough on its own to warrant keeping both. That said, I know for my uses, the Contax is more attractive and succeeds in filling the void left after the sale of my earlier ZK and I can't afford to keep both.
Thanks for reading, hope you were entertained. Some more pics demonstrating each lens being empowered by its characteristics to follow.

Thanks Wilson, glad you enjoyed it. Not so unfortunate I think, I prefer the Contax myself. It's nice to be able to choose I guess

Aside from good/not good, or like/don't like, the ZA does not draw like a classic Zeiss lens. It looks different. Some people may like it better actually, especially those who are used to Canon's tele lenses drawing. But I doubt that those who like Zeiss drawing, would prefer it over the classic Planar. _________________ Orio, Administrator

Nice presentation Kelly.
My preference based on this comparison is for the Contax. Although I must admit in a Portrait setting using either lens would give very similar results.
Here is a C/Y P85 from yesterday. Slightly missed focus. Still waiting for my new focus screen.
With a calm background as this sample has. I don't think that one would be able to tell which lens was used.

But it's not important for me, since I have found my portrait lenses in the Jupiter-9 and the Nikkor 1.8/85.
And if I was to spent serious money, I would go for the amazing Carl Zeiss Planar T* 1.4/85 ZE or a Carl Zeiss Hasselblad Planar 2.8/80 that fascinated me when I was shooting with it. _________________ Personal forum activity on pause every now and again (due to job obligations)!

Contax handles highlights with that gentle diffusion, ZA smooths them off. Different looks, but I agree. In this situation (contra lit subject), the older 6/5 formula is more desirable. Subjective opinion of course

Thanks for your thoughts - and very much again for contribution to the previous thread. It helped convince me that the Contax was the way to go for me.
As for testing the Z series here - unlikely, as it would mean also a conversion to use on my A900. I'll have only to my recollections to draw from and the images I produced with it on my Pentax K20 to refer to for comparison. I can offer that my memory is quite clear on it, and it (not surprisingly) is very similar to the C/Y. It had the same diffusive qualities wide open which attracted me to it to begin with. The coatings on the Z series were perhaps more similar to the ZA. I do note that in straight sunlight, the C/Y is less resistant to flare and loses contrast compared to the ZA.
If one could choose, I think the Z would probably entertain those in favor of the traditional Zeiss look while providing the high caliber of modern T* coating (and a warranty!).
Again, its unlikely I'll be able to put my experience to the test on this, but take it for what it is worth

Thanks Andy. I agree, in the end both make fine portrait lenses, and also as you say, the appropriate background would elicit more of the individual character of either lens. Portrait here looks very nice of course! At this size, its not really possible to see how focus was missed. Classic fast 85 look to the transition between model and background.
Kelly.
ps, I have both lenses for a while until the ZA sells (anyone want to buy?) so I can try something specific in anyone has a request. _________________ kellysereda.com

With Contax lenses, you are the warranty. Which means that unless you are incredibly uncaring, or want to deliberately damage them, they will not break. My Planar 2/135 fell on the ground from my camera (about 1.80 m height). Most any other lenses would have break. My lens just developed a dent on the filter ring. I still have it and works perfectly. I never heard of a Contax lens' iris that did break on it's own (like it happens with Jena lenses). I never heard of things such as element separation in a Contax lens.
If you just take a minimum care, a Contax lens will last your lifetime. And same goes for Leica R lenses. _________________ Orio, Administrator

Its an interesting point you make about the durability of the Contax stuff. Only from images I didn't get impressed by their appearance at first, but it is a pleasure to use, a high quality build. Having one in my hand now I do trust it will last ages - so unlike much of the typical consumer items out there.

Great, informative post. Enjoy seeing the wonderful qualities of the Contax 85 Planar in comparison to this newer design.
What I'm also curious about is how the Contax line compares to the new ZE/ZF lenses. I wouldn't want to lose any of the character the original lenses have. _________________ Vario Sonnar 35-70, Planar 50 1.4, Planar 85 1.4, Makro-Planar 100 2.8, Super-Takumar 35 3.5, Super-Takumar 135 3.5, Full Frame 5DmkII |
