I would think Chinon 50mm f/1.7 and Chinon 55mm f/1.7 are two different lenses. _________________ [C&C] on my pictures are most welcomed. |

Hmmm, you may be right, but this Japanese site says that it was made by Tomioka:
http://homepage3.nifty.com/photostreet/press/13.html
Regardless, it's a great lens and has that special something that I like - smoothness and warmth. |

Looks like they attributed too many lenses to Tomioka. 23mm is not Tomioka but Sun. There are several versions of 28mm, 35mm and 135mm lenses. None of them is Tomioka made, many of them are Sun as well.
What we know for sure is that Tomioka made for Chinon the following lenses: 21mm f3.5, 55mm f1.2 and f1.4 and 100mm f2.8. |

Yes, too many sellers like to attribute lenses to Tomioka that sometimes do not belong.
@ dimitrygo
Did Tomioka make the 100mm f2.8 for Porst as well as Chinon?
Thanks

The only Porst 100mm f2.8 examples I saw were made by Sun. It doesn't proof of course the Tomioka variant doesn't exist. |

OK, I'll concede. Not Tomioka. What's funny is that a lens that might have been an average performer on a film camera can be an excellent lens on a digital.
I have a Pentax M 50mm, f1.4, a beautiful lens with film but a bit cold with digital - too sharp really. This Chinon 1.7 is slightly softer, and I really prefer it for that.
BTW, none of the above photos are edited in any way - straight from my NEX. I did use a 2X Close Up adapter on most. |

Based on your previous posts on this subject you are probably talking about 55mm and not 50mm. |

I like the Chinon 50 1.7, even though I rarely use it I still think it is a very good lens, nice colour rendition and plenty sharp.
Wide open at f1.7, ND6 filter, 1/2 sec exposure to blur the water, which was a horrible mucky brown, so I used a Silver Efex for B&W.

Astro,
Nice work on the sunflower pics - and congrats on the great find - that's a nice lens.
As has been stated on this site many times, it is very hard to find a really awful 50mm normal lens from the modern era. Many modern (post 1960s) faster normals are standard 5/6 Planar (Double Gauss) designs (see here: https://en.wiki2.org/wiki/Double-Gauss#/media/File:DoubleGauss1text.svg ), and if they are Japanese in origin, they probably share at least some common glass supply or component manufacturing features. Minor differences aside, IMHO, the performance of many Japanese normals from the great SLR era of the pre-digital age is going to be quite consistent, and quite excellent. Lucky for us, there are some minor differences for us to talk about and collect examples of!
Your comment that some lenses seem to perform better on digital than on film is interesting. I agree with your observation wholeheartedly and I think it is due to at least a number of factors aside from bad memory or subjective perception:
1) Many of us shoot digitally on crop bodies (APC) as well as full frame. Since the crop bodies only use the center portion of the lens circle, we get images from what is typically the "best performing" part of the lens. 35mm film cameras used a much larger portion of the image circle and included the edges of the images which are typically less sharp, and prone to distortion and vignetting.
2) Modern digital cameras have great image noise control, allowing us to shoot at higher ISO's than we did with our film cameras. This allows us to subsequently use smaller apertures for a given shutter speed, and again use the "best performing" middle apertures from the lens. it also lets us use faster shutter speeds which reduces camera shake and results in sharper looking images.
3) We often save and review our digital images as JPEGs, and even if we don't do any post processing, our cameras have. This could include white balance, sharpness, and contrast tweaks as a minimum. I feel these little tweaks are by and large more effective in producing consistently good looking images than anything we had in the days of film for standard machine (not custom) processing of prints.
4) Our use of chimping on digital cameras which allows us to take multiple shots of a scene and pick the best image at the time of exposure is something we could not have done in the days of film. Having more good images to pick from might lead us to perceive images from a particular lens as better than the images we took with it on film.
5) Modern digital cameras have evolved better and better exposure and focus systems over the years, and with only a few exceptions (Nikon, Leica, etc.), film camera technology for the masses pretty much stopped almost 20 years ago. So, by definition any comparisons we make to film images have to be based on images made with much older technology.
Your Chinon 50mm f/1.7 is certainly a fine lens as your images bear out and I agree that digital cameras have allowed us to really use some of these "forgotten" lenses to their best advantage.
Cheers!
