16mm Hologon

I'm just toying around with an idea – will a 16mm Hologon fit into an M10?
 
Thanks

 

There are some examples of readily converted to M mount floating around. I think there is one now on ebay complete with ND filter.

I would consider VC 15mm.

There were two Hologons, a 16 and a 15mm. They used different center filters.

 

The choice between the Hologon 16/15, VC 10mm, 12, or 15 is not so difficult, but I've used them. The 10mm over a full 35mm digital sensor is best, hands-down.

Thanks to everyone. When I asked if it would fit into an M10, I should have said that I'm asking because I'm worried that it fits in too deeply and could damage the cameraIt 

 

 

Cannot give a clear answer, just confirm to be careful ...

 

I had a M converted 16 Hologon for a while . I used it on my MMv1 but am not sure that the M10 has the same specs as the MMv1. 

The Hologon 16 mm rear lens element extends / protrudes so much when focussed at infinity that it will touch the SL 601 mechanical shutter when using a Leica M to SL adapter, saw this myself !

 

Some strong  fall off to be expected even with the ND filter fitted, here a couple of shots with quite some post work done to clean the vignetting/fall off :

 

on the MMv1:

A deal breaker for me is the Hologon is an f/8 lens, and to make the center filter work properly, it must be stopped own to f/16 and then we have to add the filter-factor.

Yup.  It's called - photography.

Since Leica changed the width dimensions of the M10, compared with previous digital M's, I'd check this carefully. I'd imagine the exit lens pupil to shutter dimension remains the same but don't quote me on it. Maybe email Leica directly? Worth a shot. It's a great little lens & has been talked about a lot on this forum with the M8 & M9. Try a search. I hope you get a firm answer.

Thanks for this reply. I'll keep on hunting round and I'll report back here if I find out any information.

 

I don't have one of these lenses and although I have an old monochrom I haven't made a decision to buy a Hologon yet

Extracted from the M10 instructions manual, page 135.

I have no experience with this lens though.

FWIW

Well spotted. Thank you.

 

Definitely very worrying. A shame they don't give some specific guidance on the 16mm.  Does anyone know the differences between the 15 and the 16 models

 

I think we may have to wait and some altruistic (read: reckless) person tries it out for us.

The 16mm has never been a Leitz or Leica lens AFAIK but i know very little about those Hologon lenses sorry.
