Hi all!
I recently acquired a fast Fujinon 25mm F/0.85 lens for pretty cheap. Sadly, i am unable to get it into focus on any of my cameras due to the really short back focus.
I did get it working by simply holding a bare webcam sensor behind the rear element with a distance of around 9~mm. Any ideas on which cam i could possibly get this light monster working? |

No, just on Lumix. The problem is the deep protruding mount and the rather thick barrel. Maybe with some brute force mechanical mod it could be used, but not my style. _________________ Klaus - Admin

We should cannibalize a 20 USD compact to make an own Q system ...
I am really angry to Pentax they 'silly' ideas makes this company to down I am pretty sure , 10 000 USD digital 645 , Q system as digital Holga .... instead of make a solid full frame camera ... _________________ -------------------------------

They will give us an APS-C camera too, apparently.
There will be more lenses bought and sold, Attila!!!
Surely good news? They are unlikely to have competitors at that size, and attaching the camera with lens, to a key ring is a marketing stroke!
I have seen that Japanese enthusiasts have been cannibalizing the compacts, just as you say, Attila! This is precisely the market that Pentax is aiming at? Not too many perhaps, but enough to have been noticed. If it comes out in pink, apart from white and black, then we know they aim at the girly part of the Japanese market, but it is all good, surely?
Not a surprize, really, as Pentax did create that 110 slr! We now seek out their lenses for that 110 as they are good for m4/3 cameras! History repeats? _________________ ---------------------------------

That's certainly interesting! Too bad the sensor is so small though... that pretty much renders the 'wow' factor of these fast lenses useless. |

Would you have any links that show how a compact can be cannibalized?
I have an old Fujifilm F20 with super sensor that I'd love to experiment with.

The Pentax Q is a bad joke, a tiny sensor like that is pretty useless, they even have to give it some software that artificially creates bokeh as the sensor isn't capable of shallow dof. IQ maybe acceptable but it certainly won't be worth the money the camera costs.
I also doubt that old D mount lenses will produce sharp results on the Q as the resolution of the sensor with so many MP squeezed onto a tiny piece of silicon means the pixel density is very high and that means you will need a very high resolution lens to get a sharp image, the old D mount lenses were not very high resolution as 8mm film didn't require it.
The best compact cams to convert are the Canon ones as you can hack the firmware using CDHK to enable it to shoot without the original lens attached, which is crucial.
I did take the lens off an old fuji camera and fitted a d mount but it wouldn't take a picture as it couldn't communicate with the original lens. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Despite some criticisms people have had about the Pentax Q I've actually seen some good results from it for some people and while the initial retail price for it may have been a bit too much for most of us, since it's been out for a while now, I was able to buy a brand new Q Body with no lens for around $150 on Ebay.
At that price, I couldn't resist the opportunity to try out that 0.85 lens for low light photography and video. |

So to make your pic visible. Looking forward to seeing your results (considering that bold name you've chosen...). _________________ Klaus - Admin

Shhh! I've been enjoying my Q and it's image quality quite a bit, and if more people know about it, there will be more competition in snapping up the old C-mount lenses! Since Pentax put out the firmware updates to enable shake reduction on any prime lens by selecting the focal length and enable optional focus peaking, it's been a real joy to use. |

Any news on that lens? I got this lens as an addition to a 1.4/50 Planar.
As expected, it its only usable on mFT within 30 cm. Does anybody tried to modify the lens? Maybe shortenting the protruding part of the lens a bit?
Maybe Samsung NX Mini would be a good camera because of its very short focal flange distance. However, I can't find a C-Mount adapter for it. |

You can easily mount it on a Sony A7s since it has a full frame sensor and fully electronic shutter. So no modifying needed. |
Thanks for your advice but I don't think that is the way forward. Firstly, the flange focal distance of Sony E mount and mFT is not that different, only 1.62 mm. So you would still need to modify the lens to reach infinity. Secondly, the lens in not really covering mFT, so I don't think it will be of much use on FF. And thirdly, I don't have the money for an A7s. |

That is interesting, do you use just a C-Mount-adapter? Is the lens modified? Could you post a photo of the lens with the adapter?
My experience with mFT is completely different, a circular image that covers approx. 70% of the sensor. |
