Re: How about the new Heliar 15mm (Cosina) for 360 deg pan ?

 Hey Guys

    Thanks a bunch for all the answer. I'll definitely will try the sources 
for the M39 adapter.  I've already take apart a Zeiss Nettar 6x9 and try a 
dry fit. 
    The dimension of Voightlander (cosina) Bessa L body (Thickness. Front to 
film plane) and Zeiss Nettar is very close. Since the Heliar rear element 
doesn't touch the film plane and The Bessa L body has enough clearance to fit 
a Focal plane shutter, I think I'll have enough clearance to fit Heliar on 
The Nettar body. With room to spare for the slit.  I think I will have no 
problem with the rollers too. Because even though the rear element ported 
into the body the dimension of the rear element is very small. 
     I don't have my Heliar with me right now in my office but I'll measure 
the protrusion and will post it. 
    Anyway I'm very excited about this project. Up to now I have already pick 
together all the material needed to do the project with the exception of the 
Roller with O rings and the way to attach the Heliar to the body.  I got a 
very low Rpm Geared motor very high torque and will run from 4 AA batteries. 
No vibration either.  I also pick up a Children RC Toy car from Radio Shack 
for $6. I 'll use the Radio control parts and junk the car.
    I just hope I can fins enough free time to do this project.

 I'll post the dimension of Heliar protrusion and my progress 

Thanks again

<< I am very interested in Heliar lens but I am afraid of its dimensions: as 
said Sofjan mustopoh, rear part will be very closed to film plan (lens is not 
retrofocus) . Does anybody knows the exact dimensions of Heliar back part? 
Heliar lens scanned with a rule on a flatbed scanner will be good. A plan 
will be marvelous.
