FD to EF EOS Adapter
Matthew Marshall posted a topic in CamerasWe all know the cheap ones. Simple mount with a really bad optic. Is there no way at all to make or create an adapter for less than the canon telephoto original adapter at around $699 I just can't believe this is so. I mean a simple telephoto adapter with a secondary achromatic element behind it ought to work to clean up and telephoto the image enough for an FD to EF adapter. Is it just that difficult to get decent glass for a good price? Overview I am attempting to create and research an FD to EF adapter that does not have horribly unusable chromatic aberration. Testing including test shots at different apertures and comparison in lightroom. I will be publishing my findings here and possibly flickr. If you are interested message me, I would love to build a team willing to research and experiment with the project. Otherwise follow along, feel free to try it yourself and post your findings or send them to me directly if you like. Im not looking to profit here. Feel free to learn from what i'm doing here and do so yourself, id just appreciate credit. While mass manufacture is an option, I currently dont have the infrastructure to support it within my company. Id rather focus more on taking pictures and video than manufacture profit although if the opportunity presents itself I may jump at it. 5d Mark II - Testing camera Canon 50mm f1.8 FD - Testing lens 3d printer for light manufacturing. preliminary dioptric research done measurements of cheap fd adapter recorded Update - 09-15 Nominal Success in adapting rear lensing element from Canon 28-80mm f2.8 wide angle telephoto lens Effective focus distance 2-3 feet depending on fstop (f2.8-f22 examples below) Spurned by this success I am looking for lenses, broken, as is, no longer working etc. 35mm 50mm 85mm 135mm Canon preferably, I mean lets keep it in the family if possible. *note - results gained so far are with the Canon 28-80mm. Going to start work with fixed lenses and if needed ill use telescopic. General Progress Completed Successs! It works, this should be possible for less than the old Canon FD to EF adapter There should be no reason this cant be done cheaply either for other lenses or simply just the FD lenses without significant chromatic aberration Initial test pictures and examination in lightroom (I felt that CaptureOne was a bit cheating since their sharpening algorithms are so good) To Do --Find a rear lensing optic that fits Acquire Lenses - Minimal Chromatic Aberration - Minimal vignetting --Test for minimal chromatic aberration and quality Acquire test target --Test lenses (acquire) Fixed FD lenses Telephoto FD Lenses Wide Angle FD lenses (under 35mm) Comparison Pictures Shot with Canon 5d Mark II FD to EF Adapter - Cheap 28-80mm Canon f2.8 rear lensing element dioptric/telescopic value unknown, working on researching how to figure this out A usable F2.8 F8 F22 F22 - Example for detail comparison around edges Ill try to keep this updated as I go if theres enough interest, otherwise I may shift focus to a different forum.

Is there any loss in quality using a ZF lens on a Canon body via an adapter? Would having a mount professionally switched using a company like Duclos in the U.S or TLS in the UK, be any better? Alex

Help using oct-18 mount lenses with canon EFI'm looking into purchasing a set of lomo primes in oct-18 mount. I noticed that to directly mount the lens to a canon camera you have to buy either a oct-18 to oct-19 adaptor, and then an oct-19 to EF. They also make oct-18 to pl, and then pl to EF. Anyways, with either of these adaptor setups, I noticed that the oct-18 versions of the lomo anamorphic primes rear lens barrel rotates when focusing. Does anyone have any insight or experience using or converting oct-18 lomo anamorphic primes to any kind of canon EF setup???? And if so how does the focus work, or ways around it??? Any help is greatly appreciated!!
dilemma about the lens mount for BMC
milandirector posted a topic in CamerasI have one question that has been creeping out since the announcement of the m4/s mount. Originaly I have planned to use my set of Samyang lenses (8, 24, 35) and Tokina 11-16, all EF mount as the main lenses for the BMC. Now with the announcment of m4/3 all world of lenses that I have used on GH2 opens up, including my absolute favorite LOMO OCT 18 mount russian lenses, however my dilemma is, if I opt to get m4/3 camera would I see any difference on my EF lenses (as opposed to going with the original mount for BMC) as well as how to change the aperture on my Tokina (as that would have to still be my main lens for BMC)? Would it be better to just go for ZE/EF or for m4/3 in my situation? Thanks a lot!
