Zeiss ZM 35mm f/1.4 Distagon Aperture Series: Green Lichen on North Side of Barn (M240)

Get Zeiss ZM 35mm f/1.4 Distagon at B&H Photo.

A “wall test” is a very demanding test, because any lens with field curvature will have a difficult time making a sharp image across the frame for the first few apertures.

This series confirms and complements the Rusty Barn series.

Zeiss ZM 35mm f/1.4 Aperture Series: Green Lichen on North Side of Barn (M240)

With HD and UltraHD images to full resolution, and large crops, from ƒ/1.4 through ƒ/5.6 along with large crops.

The Zeiss ZM 35mm f/1.4 Distagon is a must-have lens for the Leica M shooter. It is a rare gem in being extremely sharp in a flat field, low distortion, excellent in correction for color errors, and gorgeous in its bokeh.

I just want to say excellent coverage once again. Your thorough tests have always impressed me and helped me making sound purchase. I am now going full M-mount so I sold my SLR stuff and just placed an order on the 50 AA. As a 50 shooter, I think the wider companion should be a 28, though your praise of the ZM 35/1.4 is making it hard for me to decide. I'm looking forward to seeing your review on the Lux 28. I'm at the point of analysis paralysis :D juggling back and forth between 28 and 35. I shot a 35 before but feel like it's neither wide nor narrow enough for my purpose. I guess more shooting might change that, but I was more comfortable with my ZE 28 back then.

Anyway, my main point for this email is to ask if you can include a coma test in your test routine. A quick shot of a starry sky would be sufficient I think. Studio test with LED point light could be used (like Lenstip) but I'm not sure how to set that up. Besides astrophotography interest, coma performance would give others an idea of how a lens could be used in night photography. I think this would round out all the technical aspects. Thank you.

DIGLLOYD: stars are miserably dim where I live and it's often foggy to boot. And even at 3500 meters / 11,000' elevation, the number of “good star nights” is about 1 in 20 (that is, bright enough to avoid motion blur by having a short enough exposure with an f/2.8 lens). Coma isn’t quite the right term, since off-center there are often a conglomeration of optical aberrations, so testing the point spread function is a better way to describe it. A revealing test of the point spread function in the Huge Barn Interior, Sunlit and Skylit series for the Sigma 24/1.4 Art. I am thinking of building a target to simulate that kind of situation but a bullet-hold barn works darn well, and I didn’t even have to make the holes.
