Leica M APSH and HELIUM compability

[Irene Valle Luna]

Guys, I really need some help to put in a light some difficulties with Leicas lenses.

Will next lenses could work with Helium sensor:
21mm f/2,8 Elmarit-M ASPH,
28mm f/2,8 Elmarit-M (1993),
35mm f/2,0 Summicron-M ASPH,
50mm f/2,0 Summicron-M (current)
90mm f/2,0 APO Summicron-M ASPH?

If there any possibility to put wide angle working?
Thanks a lot.

There are some other threads to do with this if you search for them, but in brief.

The current Leica mount will prevent some lenses from working because they will hit the OLPF as the rear element extends.
The current OLPFs have a flare guard on them that will also prevent some lenses from focusing to infinity, this can be cut away or you can ask Red nicely for an old style OLPF.

Leica themselves will have a new OLPF assembly that will allow their Leica M cine lenses to work on Red, this includes a 21mm, but the summilux version i believe.

The new assembly will allow a little more depth but until we see that we can't really test to see what works and what doesn't with the rest of the range.

Right now though i reckon out of your list the 35,50 and 90 will be fine. The 28 from memory protrudes quite a bit at the back? As does the 21, so you may have issues with those. If you focus so the rear element is all the way extended and eyeball it - if the extension is more than the mount itself (from the base to the metal lugs) then no way. If it's close, then it will be a squeeze if it's less then it could work okay. But be very very careful!

cheers

Paul, thanks a lot for your time. I really appreciate this.
I was just wondering if there any other possibility, like to put of EF mount, if there any types of adapters or if there any kind of possibility to put pl mount of those lenses. Something like that.
