 p.40 #4 · which lens has the most 3D POP? | |
In order: I don't know the aperture used, but most likely it was f8, as I take at least 90% of my photos at that aperture. It was taken using one of my "FrankenKameras" (i.e., cameras I've modified to provide movements) and captured with a first generation A7R, which IMO, is the best of the four A7R bodies for the type of long-exposure-at-base ISO photography I do.
I very rarely crop my photos beyond a small number of pixels to clean up scraggly stuff at the edges, so this one probably hasn't been cropped to any significant degree.
My copy of this lens is not completely distortion free, but it doesn't distort very much, either, and no correction was applied to the photos above or below.
As noted above, I use mine as a shift lens with a camera having a full-frame sensor, but due to the small size of the image circle it projects, only a very small amount of movement (2-3mm) is possible. The lens does vignette hard, which is potentially problematic, but in most cases, the image quality holds up fairly well across the frame. Mind you, most of my photography is done at night, so the edges of the frames usually contain only black sky or dark shadows and these can hide a lot of ugliness that is readily apparent under other circumstances.
For example, with this photo, the red line shows where the hard vignette starts and everything beyond it is pure black, but given the circumstances, you would never know this:

FYI, here's another photo from the same outing that was also taken using my C/Y 18/f4 and, to my eyes, also displays a sense of dimensionality as well:

As another data point, I have on hand at the moment a friend's Zeiss Milvus 18/f2.8 and truth be told, I prefer the overall performance of my older, smaller, lighter, less expensive C/Y 18/f4 for its smoother, more rounded, less sterile / clinical rendering style. Judged by modern standards, the Milvus tromps all over the C/Y, but for my taste, I'll take the "inferior" C/Y lens, thank you! 8^)

Thanks a whole lot! I appreciate the detailed information provided, and 2 more captures showing incredible amount of details and dimensionality. I have collected pretty much all the c/y and classic distagons in the 25-35mm range, Looking at these samples, make me want the cy 18/4.
Cheers,

Or is it the resampling of my screen that makes them unsharp?
