richg101 Posted November 9, 2013 Share Posted November 9, 2013 I'm interested to know how many of the guys here have rama's with the 36mm rear element but also single coatings. Mine is single coated for sure, yet has '36' on the front ring. I did a direct comparison between a pre- 36 model and mine and the flares are exactly the same as the pre 36/non 36 version with the smaller rear element. just curious really since it seems a lot of people are hankering for the pre-36 version without realising that there are infact some 36's which are single coated.

Tito Ferradans Posted November 9, 2013 Share Posted November 9, 2013 Mine's the real 'pre-36'. Smaller rear element, and no mention of the number anywhere on the lens. Quote Link to comment Share on other sites More sharing options...
elubes Posted November 10, 2013 Share Posted November 10, 2013 i have a true 36 with the large backing. just don't know which. are there any markings or anything to tell if it's multicoated or not besides the mc designation? i know some are not mc designated and still multicoated.

Set a tungsten bulb up ans your light source and use the correct wb setting and if the flares turn out to be amber/bronze with a secondary green flare it means its a single coated version Quote Link to comment Share on other sites More sharing options...
Rob Bannister Posted November 10, 2013 Share Posted November 10, 2013 I know I asked this before but does the larger rear element give you a bit wider FOV before vignetting at all? Lucian 1 Quote Link to comment Share on other sites More sharing options...

starcentral Posted November 10, 2013 Share Posted November 10, 2013 I just got my pre-36 and will be trying the tungsten light source test to see what turns up. Quote Link to comment Share on other sites More sharing options...
richg101 Posted November 10, 2013 Author Share Posted November 10, 2013 I know I asked this before but does the larger rear element give you a bit wider FOV before vignetting at all? if there were any difference I assume it would only show up when using very wide lenses on smaller sensors rather than on typical 50mm and up taking lenses on aps-c and full frame. Since the rear element on the non 36 version is still very large, and can be positioned very close to the front optic of the taking lens this difference would only be seen on taking lenses with huge front optics. I'd imagine the '36' might have a slight edge in terms of light loss when using very fast lenses, but it would be very slight. when testing the two against each other on a helios 44 the results to my eyes were as follows:- flares; exactly the same brightness: exactly the same fov: exactly the same contrast: 36 was slightly lower contrast than the non 36. Personally I couldn't choose which I prefer. The difference was so slight it's not worth even considering IMO. Quote Link to comment Share on other sites More sharing options...
