First off, this lens is all manual and has an M42 screw mount that makes it easy to adapt to just about any film or digital SLR camera. That said, it will not give you any of the modern conveniences except possibly aperture-priority automatic exposure (camera sets the shutter speed), and even that will depend on your camera supporting non-CPU lenses and you the photographer properly operating the preset aperture system. Of course, it is manual focus only and the focus confirmation feature of an autofocus may or may not work depending on your particular camera and the particular M42 mount adapter you use (my lens came with a "chipped" adapter that allows focus confirmation on my Canon 6D). Oh, this lens is massive. It is not too long, but it is VERY thick, and VERY heavy. It is built like a Russian tank and should survive anything and everything a photographer him or herself can survive. Build-quality is more than just strength, and here the lens also impresses me. The aperture and preset ring are very smooth, with definite click stops for each full stop, but a very smooth and well-damped movement that is in no way difficult or tight. Focus isn't quite as smooth, but its not bad at all and far better than manually focusing any autofocus lens that I have. I used to own a Carl Zeiss 135mm f/2 APO Sonnar ZE and that lens had the smoothest manual focus of any SLR lens I had ever used. I also use Leica M mount lenses that are all supremely smooth. The Helios 40-2 isn't on the level of the APO Sonnar or the Leica lenses, but it is fully equal to the old manual focus Nikon and Minolta lenses I used in the film days, better than most, worse than a few. Okay, enough about build, how does it perform? In a word, great. This is not a modern design, and it doesn't perform like one. It is soft at wide apertures across the entire frame (often a good thing in a portrait lens) and while it sharpens up nicely stopped-down, it never get critically sharp in the edges or corners. The center is adequately sharp even wide-open, just not critically so. From about f/2 in the center it will rival just about any modern portrait lens for sharpness, but this is also a rather low-contrast lens, which again is often a good thing. Colors are muted and beautiful or dull and lifeless, depending on subject, lighting and of course your tastes in how lenses render. I use a Carl Zeiss Jena 5cm f/1.5 Sonnar from 1937 and a modern Zenit 50mm f/1.5 Jupiter 3+ (same optical design) on my Leica cameras and those lenses are similar in their rendering of color, and it happens to be a look I really like. Your mileage may vary. This lens flares easily. It is coated, but the designed is very old (1920s) and there is a whole lot of glass for light sources to flare against. I use a cheap rubber screw in hood (67mm) which does a great job reducing flare unless a very bright light is in or just outside the frame. While it flares, those flares can be very artistic, and often I remove the hoods on my lenses to accentuate flare. Portraits with this lens have a very classical look that I really like. I recommend using it on a lower-resolution full-frame DSLR or with a film camera with a traditional (rather than T-grain) emulsion for optimum effect. I use this on a Canon EOS 6D (20 megapixel) and my old EOS 650 film camera loaded with Tri-X or HP5. For Nikon users the 16 megapixel Df would be a beautiful match for this lens, though make sure to get the actual F mount model as an M42 with an adapter will not focus to infiniti on a Nikon camera. The last thing I will discuss is bokeh, or the quality of the out-of-focus rendering. Bokeh is not how far out-of-focus things get, which on an 85mm lens at f/1.5 is extremely far, but rather how smooth and nice those area look. This is a mixed bag with this lens. At times this lens produces the most beautiful bokeh I've ever seen, and at other times it is busy, swirly and even nauseating in its creation of implied motion or vertigo. I do not like the bokeh at all with regards to leaves and the like, but with larger more amorphous forms it is a real cream machine. My advice; try it on a variety of backgrounds and at a variety of apertures. This is a very creative tool when used right, and absolutely the wrong tool in other applications, and that is just with portraits. I love the bokeh for background people and on the street. I give this four instead of five stars just because the weight really is quite extreme and will prevent casual carrying of this lens for me. It is considerably heavier than my modern Canon portrait lenses (100mm f/2.8 IS L Macro and 85mm f/1.2 L mkII), and can be a real drag on the shoulder for a long day. For studio or location portrait shoots though, this lens should see a lot of use, switching off with the two Canon lenses for a modern or vintage vibe in the final images.Vollständige Rezension lesen

There are a number of lenses known for producing unique bokeh: The Helios 40-2 (85mm) and 44-2 (58mm), the Petzval 85 and 58, and others. But for cost savings (except for the Helios 44-2) and the same or similar results, the Cyclop gets the job done. It's heavy (it's chassis is probably cut from a Soviet tank) and it's quirky and sometimes unpredictable. It can be difficult to focus (and that's all you can with it-- focus) but the results can be wonderful. The Cyclop was designed as the optical component for a night-vision rifle scope for the Russian military. They were only manufactured from 1991-94. They're stuck at f/1.5. Period. That's it. There is no internal diaphragm or blades. There are no aperture controls. Exposure adjustments are performed with ISO and shutter speed only. (Plus you could add ND filters to the front for more exposure control.) The Cyclop isn't cheap, price wise, but they're not overly expensive. I've had mine now for about a week and I'm totally in love with it. With a simple M42-to-EOS adapter, I mount it to my Canon 5D2 and I'm ready to rock & roll. I recommend this lens (which isn't really a camera lens, per se, and probably isn't for everyone) to anyone who wants to capture images that lean heavily to the different and unique side of photography.Vollständige Rezension lesen

Love this lens! It produces such beautiful swirly bokeh. It's great that it comes with specific camera mounts (in my case Nikon) so you don't have to use an adapter. And although it's a bit heavy, it seems & feels really well made.
