Here is a true Mandler classic, the Tele-Elmar 135 in M mount. This copy from 1970 has the removable head. I have Fotodiox adapters for my 1Ds and D3X, and also OTZFO for my OTDYM. I would call it my favorite portrait lens except that it is a bitch to focus, especially for selfies. That it is not an apochromat is apparent with modern digital sensors (slight color fringing w/o), and that is sometimes a problem. Image taken with D3X, one studio light, f/11:
I've been lately shooting the D3X with Sigmas 35 Art and 70/2.8 macro, and the TE135 can actually compete for sharpness. The color rendition is completely different: no surprise for a design released in 1965 and with single coatings.
A few more touristy snaps from Spain (R35/1.4, 80/1.4 on A7R).
Having recently used a pre-FLE Summilux-M 35, which is sharper wide open and has more contrast and a flatter field than the R, I still prefer the R's rendition and especially colors.
"But when it comes to the overall feel of the image, especially in digital or slide photography, I still find the Mandler designs to be "miles ahead" in terms of rich tonality and the handling of color rendition (as opposed to color correction). For me, it's as clear a difference as that between a Beaujolais and a Bordeaux - one is bright and gay, but the other has infinite depths.
It has been my consistent experience with the M8 that the current designs (except the f/1.4s) push detail off the ends of the tonal scale, where even raw processing cannot recover it. It is normal with them to have exposure set to -1.00 (using ACR), shadows to 0, contrast to 0, and still have a "hot" image. Whereas with the Mandler designs, the same lighting will give exposure "0", or even plus a bit, shadows at 5 or higher, and the midtone contrast can be set as high as 50, giving a boost to midtone separation and saturation. In other words, at least a stop, and more like two stops, of additional dynamic range. And generally a bit less noise, through not having to dig into the shadows as much in post-processing.
I also find the older design telephotos to be more forgiving for RF use. They usually have longer focus throws, which allows for a more precise vernier touch in putting the RF images together carefully.
And the residual spherical aberration means that while they are not always as precisely sharp as the APO teles at full aperture, the zone of "reasonably sharp" covers a slightly wider depth of focus at the image plane. The width of the bright area, left to right, in this example: File:Spherical-aberration-slice.jpg - Wikipedia, the free encyclopedia
All this is why I posted this thread in the first place - on MFT charts, and in some imagery, the new advanced designs from Leica are certainly state-of-the-art - or even ahead of the art, when it comes to the 21 and 24 Summiluxes.
But over and over again, I have gotten pictures that please me more, technically, from the Mandler designs. And ultimately, it is those pictures, not the MFT charts, that I publish or hang on my wall."
A7r Mod and M28 Elmarit v3. This lens is a sleeper that has wonderful rich tonality when combined with the A7rM. I have yet to try it on the A7s which has great B&W conversions.
