Probably one of the best standard primes with the K-mount. Tomioka made, equalled by SMC-A 50mm f/1,2. Yoshiro Takinami writes on Rikenon 55mm f/1,2 (same optics as Revuenon) in the "Best normal ?" on Stan's Pentax Photography: "I prefer Ricoh's Rikenon 55mm/F1.2 to any Pentax 50mm lenses. It's really a great lens, I think." http://stans-photography.info/ Another review compares it (again Rikenon version of this optics) with Fujinon XF 56mm f/1.2 lens - 1300 USD - where it holds it's own with no problem: https://jonasraskphotography.com/2015/02/10/rikenon-55mm-f1-2-review/ At f/1,2 in full summer sun it snaps objects in "paper thin" focus with no question. From f/2 up IT IS SHARP. Good hood recommended when wide open. No complains, great lens.

Excellent colours, bokeh and sharpness in very compact, cheap and easy to buy lens. Today I tried some pictures in extreme condition - against direct light from a 100W flashbulb. No flare, and no ghosts at all. I was impressed.

Another classic lens from Carl Zeiss: SONNAR 300mm f/4. Thanks to it's newer design it weights "only" 50% more than SMC-K 300mm f/4 - not 100% more as with old design "Zebra" type. The lens can be used handheld. Due to it's weight, it is very stable, so shutter speeds of 1/30 - 1/50 are not a problem at all (thanks to SR). Lens is fully usable wide open, from f/5,6 on it is VERY sharp. I didn't have any problem to get crisp images few minutes after I first tried it. Colours are warm and saturated, bokeh very natural and pleasing. Crisp sharpness of the main subject and subtle tonal transition (due to simple Sonnar design) together with great bokeh creates great 3D effect. The lens handles like a Takumar with working aperture metering on Program - which is what I like very much. Pentacon Six/Pentax adapter is a must, big screw-in sunshade is included in a set (same size as CZJ Sonnar 180mm f/2,8).

Superb lens! Exceptional sharpness wide open at closest range makes it great MACRO WIDE ANGLE lens indeed. Seems sharper in comparison to my SMC-K 28mm f/3,5 which really surprised me. Slightly softer wide open, but still well usable. Colour rendering is slightly cooler than SMC-K 28mm f/3,5. In low light with K5 at ISO 6400 gives very good results. I'm lucky to have this glass.

Carl Zeiss 180mm f/2,8 Sonnar lens with PENTAX mount - if it ever existed - I would expect it's price to go high over my abilities. This Pentacon Six lens I got almost new in my friend's shop for good price. Fully usable wide open, SHARP after next 1/2 click, VERY SHARP from f/4 on. Strongly lit, contrasty scenes at f/2.8 will be rendered with some "portrait softness", but after 1/2 - 1 click all is ok. This classic Zeiss lens handles colours and especially skin tones in superb way. Combined with Pentax imaging software and 16MP sensor of the K5 - you get very good results. CA is rather expected on classic non-ED tele glass. Post processing handles it with no problem, so I don't list it as a drawback. Size and weight should be taken under the consideration, but any 180-200mm f/2.8 is big and heavy. I have no problem to use it hand-held and thanks to SR - 1/30 is not a problem. The lens is actually quite compact (thick in diameter though) and a screw-in sunshade is included. Good lens, great fun! Carl Zeiss Sonnar 300mm f/4 in P6-mount is another story. See my next review.

Original Pentax SMC-M 40mm f/2,8 seems overpriced in Europe. I never decided to spend over 150$ just for the flat glass. This one I got by accident, checked if has clean glass and if it is decent sharp wide-open on my K5 with 9,5x magnification. It is! The rest is just pure fun and joy!!!
