The discussion of the Contax 100-300 Vario-Sonnar seems to be archived, so I am not sure how to continue it. Below are addresses for the first and last pages,

Here is a fall shot taken with a Sony Nex 5 around 300mm and near the closest focus of a meter and a half, exported from Lightroom 3,

Thanks for posting the link. Phillips comments on the lens is very enlightening.

So finally I have my camera back and tried out the 100-300 today

I took out a power line running across the lower third. It should've been tricky because it was out of focus, but Photoshops content aware heal is really amazing!

Here's some of my shots with it - from the other thread:


Contax Vario-Sonnar 100-300mm All wide open:




Hand Held, 300mm, 100% Crop







Hand Held, 300mm, after sunset, 100% crop







HH, WO, 300, 100% - got a little camera shake in this one. ( ;"- /







WO, About 250mm




100% Crop of above






Pretty much SOOC... Only BFR-Scaling on the next three here (actually for the above heli and the blossom too) - it doesn't need any contrast boosting or anything like that - and as you can see it's already so sharp that even just BFR-Scaling adds halos in some places:



100mm WO:







100mm WO







300mm WO







100% Crop of above





ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー


Here's some Aperture (DOF / Bokeh) animations at 100mm. The first one is the full image scaled and the second one is a 100% crop. It's got some pallet dithering noise because I used photoshop to create these - probably the worst app for GIF optimization and Gif-amin editing! But anyway, that shouldn't matter too much, you can see the what this lens (the C/Y Zeiss Vario-Sonnar 100-300mm f/4.5) looks like in full color in the above posts.
















These are without any editing except BFSG-Scaling on the scaled one, and all sliders set to 0 in ACR.- (not default, but zeroed).



ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー


Here's some more of the C/Y 100-300 but at 200mm WO this time:









Almost a 100% crop from above. But rotated for composition - which I guess you can tell I suck at.
It would have been 100% but I wanted it the same width after framing so the scale value for that came to like 92.x%
Hehe..




And another of basically the same kinda thing 200mm, WO, - although the crop version is actually from a different image taken just after or right before:

Bifurcator, what do you think of the colors from this lens? You have used so many different types of lenses, with different characteristics, I have wondered what you think of this lens's palette?

Jotdeh, which mm were you using?

The first one (church tower) was about 135 mm and wide open.
The office building was 300 mm or very close to that, and wide open, too.

Hi Inglis, are you using the 100-300 + Mutar on a full frame camera? I heard it might interfere with the mirror on 5D... Definitely interested in more samples of this combo either way!

Why not just use a teleconverter with EF mount? C/Y adapters are not quick to remove from lenses.

Good point! Any extender samples would be cool! Zeiss says the only converter that works (Mutar III) there will be strong vignetting. Wonder if it'll be the same with Canon or Kenko extenders.

This lens can be considered to have "good" sharpness and CA.

Crops are at 300
Note this was hand-held, around 200 mm at F8, shutter speed of only 1/250 s (so may well be a bit sharper if I used a tripod, MLU etc.) Just standard LR3 sharpening and "Strong Contrast" tone curve to cut a bit through the atmospheric haze.

I've used the lens with Mutar I and II. Saw no difference, and no vignetting (on 1.5 crop).

Thanks Brian! It shows some significant CA in the right edge, but overall still quite remarkable performance!

I actually removed the rear element for the cleaning of mine 100-300.
What's weird is that it looks cloudy, but I it's a solid glass according to the diagram. Both sides of the element appears to be fine though...

Are you looking at the diagram in the Zeiss data sheet? That one only shows 7 groups. The 12 elements are not depicted individually.

That would be the one. Is it possible that the rear element is actually a group of two? I can't seem to be able to take those apart - they sit tight in the retention ring..

Actually, if you zoom right in you may notice a small discontinuity in Groups 1, 4, 5, 6, 7 (which nicely adds up to 12 elements, too). Group 7 is what you are looking at, and the haze may well be at the cemented interface.

Similar to glue separation?
