Very rare 1954 scope by Chrestien. Been sitting in a shed in France for 40 years and normally the grease gets solid like toffee, but with this one the grease has actually crystalised, wow!   Anyway its undergoing a careful teardown for a lube and I found a ball race....   Looking forward to the super smooth focussing when its back to spec  

Cinekon were badge engineers...   'tis a lot of loot for an unknown :P   1.75x stretch MIJ, so probably a Kenko   I feel I didnt miss anything, besides its probably no good for wide apertures

I like it.     'you got some moves on ya' man'     :)

Do you know of anyone using a zoom close up with these babies, like the old HOYA units back in the day - typically 1-10 diops of zoom   They are cheap to buy so crap for stills but maybe useable for vids

How does your baby ISCO differ from the other design like this one in terms of performance etc ,,,    

First the good news   The front element is a spherical element. Which means it is easier to replace. Looks like someone has tried to remove the coating using metal polish.   I suggest take it to an optician who can remove it, test it and tell you the prescription. Then buy an equivalent from Edmund Optical.   The rear element I have not seen, I suggest you shine light through and take photo for me to comment

maybe less rare from today     http://www.ebay.co.uk/itm/Anamorphic-Moller-Anamorphot-30-2X-attachment-Prime-cine-movie-Lens-Arri-RED-/121072856667?pt=Camera_Lenses&hash=item1c30812e5b

plus one for the 2x

This must be the Moeller club!   I have mint condition one in satin lined presentation box :P     However I want a Rectimascop 32/2x for the nice warm looks they have, but sadly I have never seen one :(   I cant even find a picture of one on the web

Maybe he should change the name to The Dog's Bolex :P    

Came across this in my search, interesting bayonet mount   Front element is 4 inch glass !!   http://www.kevincameras.com/gallery/v/movie_len/moller_anamorphot_30_2x/

Reported: I have reached a tipping point with the flame bait remarks and foul language consistently directed at me from this member and draw your attention to it      

Not sure what you mean   I am referring to the Takumar behind the Kowa  as presented in the video - a more effective solution is the Sony E - OSS 1.8/50mm without need for LionsGate.        

It reminds me of the intro to a Lionsgate movie   BTW since he is using a Nex, all that is needed is the 1.8/50 auto focus lens at the rear and job done! 

Made by Rathenower in GDR - never seen one - wondered what they look like  

  its a SK Cinemascope from the 90's, dioptr is a +1 from China  

Shot with a 2/90mm at 1 metre, aperture reflections are consistent across the FOV        

Seems to me that no one has come up with the correct answer so far..... :P

Do you know how to reroute the video feed from EOS Utility into VLC?

There is a similar concept here     http://www.ebay.com/itm/150977888123?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1586.l2649    

I am sure many have had their heads turned by the Metabones Speed Booster. Some of the many have wondered if this concept could be adapted to scopes.    Out of respect for the two forums, rather than paste a link I have reproduced my info below.     It doesn't mean anything but it might mean everything  :P       ============================================   JohnBar wrote: Hello Brian  I completed an inquiry form at your website in connection with an anamorphic interest.  1 Did you get it?

Sorry.  Anamorphic is something we are thinking about, but I can't say anything beyond that right now. _________________ Brian Caldwell

Here I have a Helios 44-2 2/58mm lens (my James Bond lens 'cos it has serial N007xxx).   By just balancing a +8 dioptr on the back I can increase the FOV about 2x - magnification is reduced to 0.5x   Looks pretty good to me :P      

Thats because your TC lens is still a negative lens - it has to be positive to work     Try the dioptr trick I posted earlier - I will post pix to show you in a minute

if you are looking for a fun project, then try placing a +8 dioptr between the lens and sensor in say a tube and play with placement position :P

TCs are optimised for light flow in the 1.4x direction. To make them work in the 0.7x direction it is more that the simplicity of reversing the unit (which is only relevant for proof of concept), because the lenses have to be optimised for minimum aberration in the 0.7x direction.    If you want to do private study in lens design an excellent book is 'An introduction to Lens Design with Practical Zemax Examples' by Joseph Geary.   Zemax is not cheap (about $10k), but sometimes you can pick up an older and legitimate version on places like ebay.
