Hello.

Who does really good work with this conversion? I want a rangefinder coupled M-mount Canon 50/0.95. I am delighted with the results from my Canon 7s and Canon 50/0.95 but I really would like to simplify my life.

Any 'leads' would be genuinely appreciated.

Search this forum. At least one member, Colyn in Fort Worth, had it done.

ADDED: johnastovall of this Forum also had it done.
 
Hacker, would you take photos of the mount when you get the lens back?

Many of these conversions seem to reflect the skill and ingenuity of the tech performing the work. Although I would prefer to see just TV lenses converted, I am interested in seeing any of the conversions.

With the massive weight of the lens, I also wonder about the wear problem with the use of only the screw mount. Canon realized the potential, which was the raison d'etre behind the design of the larger, heavier outside mount they utilized.

I believe that the TV lens that is converted by him will not have dirt enter the helicoids. A tool may be needed unmount the camera. Again, this is what know but not what I have read.

Once mine is ready, I will have the photos. In the meantime:

A few more questions, I take it you have to send your M body along with the lens?

Even though you're having this conversion done right now, any speculation on how it takes?

I did not send my M body, and it will not be necessary. It takes about 5-6 working days.
 
Check this out:

Classic Camera Workshop now offers the Conversion of the worlds fastest normal lens, Canon's legendary 50mm f0.95 lens to Leica "M" mount. Once converted the lens will fit all cameras that accept the Leica "M" mount. I can even add the 8 bit coding for the M8. This coding allows the camera to digitally correct for the optical characteristics particular to this lens.
The conversion includes the following:​
  • Conversion to "M" Mount​
  • Adjustment of RF cam on camera version​
  • Fabrication of RF cam on TV version​
  • Machining of barrel as necessary​
  • Clean diaphragm​
  • Overhaul focusing helicoid assembly​
  • Minor repairs and adjustments as necessary​
  • Clean optical cell groups​
  • Adjust for proper focus​
Pricing with customer supplied mount​
  • Camera version.............$150.00 ​

    [*]
    TV version.................$180.00​
CCWS supplied mount​
  • Camera version.............$210.00​
  • TV version.................$240.00​
  • Programmed for the M8 add..$ 60.00​
All prices include insured return shipping in the USA....International add $22.95​
 
For what its worth I recognise the mount in the photos. It is the back mount from a Visoflex III that allows attaching the unit to the camera without twisting it round.

So as more .95 lenses get converted the Viso III will become extinct!

Globally we are eliminating at least three species of rare photographic accesories every day!

Save the Viso family before it is too late!!!!

I urge you to rise up and march on your local photographic retailer this Saturday and demand a roll of Kodachrome 25, a set of exposure tables and some flash bulbs!!!

Hello.

I have been very busy and that is why it took me so long to photograph the m-mount conversion of my Canon 50/0.95 TV lens.

I am quite pleased with the result.

No Canon 7/7s/7sz 50/0.95 lenses were harmed in the process. 😀

That might be true Michael, but since we all are running out on time to shoot film (it will all end one day, regrettably), I hope to combine the best of both (or several) worlds in order to shoot with a top-notch set before it's a pretty paperweight.

I can confirm that the Canon 7s rangefinder is MUCH less in quality than the rangefinder on a Leica M3. The M3 I own has a deteriorating mirror in the rangefinder setup (looks like tiny hairs on the rangefinder patch), but still is way easier to focus than the dim patch on the Canon 7s.

The rangefinder in the 7s I own is a bit cloudy, does anyone have experience with cleaning this? Is it a DIY job or should I get someone to do it for me?


Cheers, Johan
