Lynx heresy

[someonenameddavid]

In another thread, it is mentioned that is is technically possible to have the lens adapted to another camera ( I assume Leica) has anyone on this forum actually done this.... And did it cost less than $250???

I've seen a couple of stories on the web of people adapting the Electro 45mm f/1.7 lens.

Interesting to see, but not a reasonable economic proposition!

Well, it would be possible but a conversion to Leica would be difficult and expensive. The only threads I've seen involved DIY adaptations to m43 where super precise flange distances aren't required.

Super precise flange distances are required on every camera or nothing would ever be in focus. The real problem with adapting the Yashica lens to Leica would fabricating an RF cam follower.

I also heavily flamed the Yashica G series cameras as junk and stand by that flame. However, I was a little harsh on the Lynx, in retrospect.

I also believe I did real justice to Yashica AND the other lenses and cameras they have had success with. I did not flame Yashica... I flamed the G series cameras as junk.

I have read repeatedly about re-mounting Yashica and other "glass" in different mounts. As regards the expense, I regard the projections of "very expensive" simply an example of something common to most forums... "WAGGING". I see no corroborative evidence that precludes the fact that it may actually be "relatively easy" and reasonably expensive.

If you would use the search function, you would have, in about a minute, found this thread on this very Forum... RFF.

Do you need my assistance in any other way? I may be willing to devote another minute or two and come up with more information.:bang:

Wrong!

When you focus at the film/sensor plane (view camera ground glass, digital live view focusing) there is no need for the lens to have any standard flange distance. Even with surrogate film/sensor plane focusing (read: SLR systems) there is no need for precision.

In fact, there is no standard or consistency in the mounting flange of lenses made for view cameras and they work very well. The flange only needs to be close enough so that a reasonable focusing range is available. Most of the inexpensive legacy lens adapters for the digital mirrorless systems take advantage of this. They are intentionally "too thin" letting the lens focus past infinity to eliminate the need for more expensive precision during manufacturing.

Here's an example, Electro GSN lens on a Sony NEX. I doubt this is a reasonable economic proposition, but it sure looks neat.

The precision is required for a Leica adaptation because the focusing will be with the rangefinder.

Less precision is required for a digital camera that focuses with live-view because you are focusing the actual image on the sensor.
