#Hugo meyer 25mm f1.5 full
A comparison of the bokeh and rendering of 35 vintage “normal” full frame prime lenses. Bokeh Tales (shots with various lenses known for their bokeh). Spreepark: an abandoned amusement park in Berlin. Silent Summer: a ghost town in Fukushima. Gunkanjima: post-apocalyptic vision of a future past. Ode to the Uebel “Cigar” (a unique Boehm flute). A rare little beauty–Selmer Modèle 26 sopranino saxophone. Another Stowasser tárogató–in B natural!. A Tárogató Odyssey: finding an original Schunda instrument. A most singular tárogató–Stowasser in C with a surprise…. These lenses are, AFAIK, copies of the Zeiss Biotar 75mm f1.5, which costs much more and IMO does not really have a very different rendering. This version seems to be optically better, but it does lack some of the very characteristic sharp-edged bokeh that I like so much. One warning about the Helios 40-2 is that it comes in a new version, with Nikon and Canon mounts. There is a standard photographic version of the Cyclop f1.5 named the Helios 40-2, which does have a diaphragm but costs quite a bit more. The Cyclops do not have diaphragms, so always are at full aperture. I prefer the f1.5 version, as the f1.2 version has serious vignetting and a lot of chromatic aberration, as well as being very soft off center however these lenses are cheap, and I’m betting that the f1.2 version could also make some nice images, although I don’t have one. 
Luckily there are versions of both that have a standard M42 mount. These come with M42 screw mounts, but some care must be taken, since both come in several versions, some of which have a long extension on the back of the lens, which must be removed to mount on a digital camera. There are a number of versions of the Cyclop, the most notable being this one and an 85mm f1.2 version. There are a number of interesting Russian lenses for bokeh fanatics, and one of the best and cheapest is this one, an 85mm f1.5 lens made for a night-vision device.
