I have an LTM to Sony E. But since I wanted the max helicoid, I bought the most 
expensive form. Namely a Shoten L.M - S.E Macro with 6mm of extension. 5mm or 
4mm is less expensive. Then I just put an M39-L/M thin adapter on it. I posted 
this link I think before:


A bit outdated as the price has gone up and the Voigtlander VM-E is no longer 
made, only used versions can be found. So a VM to Sony E with M39 - VM.

As to best value/choice they all vary. For instance the FotodioX M42-NEX/M is 
very nice. But the FotodioX Pro Stretch PK-E is very heavy and clunky. While 
the YEENON PK-E Macro is very nice by comparison. I hated the fotodiox PK-E 
stretch so much I got the YEENON PK-E. YEENON makes very nice adapters but 
usually ship from China.

(all photos below are in https://photos.app.goo.gl/TR5Ud27mgL5cvdoJ8, which I 
have shared before).

Another fine adapter is the Kipon OM-S/E M adapter with helicoid. Used here 
with OM 50mm f1.4:

I'm not the best the person to ask about price/value.

I have a few PK mount lenses:

Cosina 55mm F1.2 (58mm filter thread)
Rikenon P 55mm F1.2 (58mm filter thread) - these two I think are the same lens
Porst Color Reflex 55mm F1.2 (55mm thread) - not the same as the two above

Minolta MD mount with Vello LA-NEX-MD-M (helicoid):
Rokkor - PF 58mm F1.4
Rokkor - PG 58mm F1.2

The majority of my alt lenses are M42. The one I like the most is the Takumar 
early 8 element 50mm F1.4. You can tell that lens by the IR red line on the 
right side of the 4 on the DOF gauge. While all the later 7 element version it 
is on the left. You can see here:
Here using that lens with the helicoid:

I recently acquired a Helios 44-2 early version M42. It is supposedly sharper 
than the more mass produced later versions. I have yet to test it out. Also on 
the M42 lenses to test is a Topcor 5.8cm F1.8 and a Cosinon 50mm F1.8.

As for the FTL OM M42 lens, most all my m42 lenses have the Auto pin and it has 
never been a problem with the adapters.

I'm curious if the G. Zuiko FTL lens is the same as the OM mount early G. Zuiko
