Re: Have 5D, which is the best R-lens adaptor?
Hello again - Iron Flatline,
Another thing you should know about the Haoda-adapters with electronic contacts is that the adapter tell the Canon digital camera that you have mounted a 50mm lens with a max aperture opening of F/1.8 (!)
Please see the difference of the exif-datas on the two attached pictures. The Canon 350D camera was set to Av-mode and F/3.4 was selected on the Leitz 180mm APO-telyt lens. One picture was shot with a Novoflex adapter attached and the other with a Haoda adapter attached. Otherwise the pictures were shot under the same lighting conditions - same ISO settings - same light measuring mode - and now comes the interesting part:
With the Haoda-adapter attached the camera selected a shutter speed of 1/320 sec
and the the Novoflex adapter it selected a shutter speed of 1/125 sec.
Why this difference (?) I do not know (!) It could maybe have something to do with the information about the focal-lenght and maximum aperture value to do given by the Haoda adaptor (?)
All the best - Svenning, Denmark.
