p.1 #1 · p.1 #1 · FE 70-200/4G vs Zeiss Sonnar T* 3.5/100 C/Y


When carrying lenses on a strenuous hike, a compact telephoto is greatly desired. The Zeiss Sonnar 100/3.5 fits the bill. It's small, well-built, inexpensive and has great IQ.

It took me a few tries to get great copies of the FE 70-200/4G and CY 100/3.5 lenses. The Sony 70-200/4G has its sweet spot around 100-150mm so it was a challenging test for the Sonnar 100/3.5 prime.

The results are:
  1. At f/5.6: The Sonnar 100/3.5 has better resolution/contrast at the extreme edges, but has a slight dip at mid-frame. Both lenses are very similar at center.

  2. At f/8: Both zoom and prime are very close. The Sonnar is still slightly ahead at the very corners but they seem very much alike throughout the rest of the field. Similar to f/5.6, the zoom is still tiny better at mid field.
There is more LaCA on the 100/3.5 images but I prefer its rendering and bolder colors.

Carl Zeiss Sonnar T* 3.5/100 C/Y Specifications:
  1. Lens Composition: 5 elements in 4 groups
  2. Angular Field: 24 degrees
  3. Minimum Focus: 1m/3.2ft
  4. Stop Scale: f/3.5-f/22, manual
  5. Filter Size: 55mm
  6. Weight: 285g/10oz
  7. Dimensions: 61x61mm/2.4x2.4"

Here are the extreme edges, mid-field and center crops: (below)

Sharpening in LR (50, 0.7, 25, 0)

Looks great! I've never considered the C/Y before and didn't realize how tiny it is. Wow!

I might have to grab one of these as well. Seems like a good mate to the Voigtlander 180mm f/4.

BTW: I tested it with the Kipon Contax to Nex adapter with Helicoid (extra 12mm)

So, the magnification goes from 0.13x (1:8) to 0.25x (1:4) in macro mode when using the helicoid at its maximum height.
The FE 70-200/4 offers the same magnification (0.13x). You would need to add a 12mm extension tube to get to 1:4.

I recently picked up one of these as well. Nice colors and contrast. I don't have the 70-200/4 but I do have the 70-400G2. The C/Y 100 is tiny comparatively and the images are wonderful.

Thanks for the comparison. There are a lot of choices in this focal length (85-100mm). Some are faster, cheaper, smaller, lighter, even sharper. It all depends on how one plans to use it really.

I got the latest FF version of the generic Chinese helicoid adapter for $35. Infinity focus is spot on, helicoid smooth, centering good. And a lot cheaper than Kipon. Of f course I may just have got lucky, but I was so pleased I got an OM version as well for my old OMs, and it too is spot on. Helps to flock them: the black finish inside is just a little too shiny, and also tends to reveal some silver bits of the lens mount. But that's all true of the Kipon.

I'm pleased to see the S100 C/Y (a long-time favorite of mine) getting the spotlight, and even keeping up with modern designs.

That one has some crazy extension.

This one extends about the same as the Kipon (12mm)

I just purchased a Minolta AF 100 f/2 from a fellow FMer. From the pics I have taken I'm really impressed. Using the Sony adapter with the A7R II reduces the number of AF points but this doesn't seem to be a real problem. It is also fairly small and lightweight. I wonder how it compares to the two similar lenses that Fred reviewed.

They all look pretty similar though!

But some of them vignette on FF cameras, having been optimised for NEX. The one I got is fine on the CY 100 -- no vignetting. And on the C/Y 35-100.

The one Guy linked to warns of vignetting on FF; but then so does the Olympus one I got, which is fine at all focus distances on the Zuiko 50 3.5 macro. I haven't tried it on wide angle, though. The little guys are super handy on 1:2 macros: with no more space taken up than a normal adapter, you can get most of the way to 1:1...

Hmm why not use a 90mm FE Macro instead?
