Hello out there,
i feel fine with my adaptor bought via ebay at fotodiox to be used with a EOS D5. Nevertheless, some corrections have to be done at the rest notch especially due to wear out of the hooking grooves in my R-lenses.
Further, the Elmarit-R 2.8/24mm firstly caused problems because the holder of the back lens was too long and thus caused irritations of mirror movement of the D5. A shortening of the holder of about 0.5 mm (and a suitable re-blacking of the brass) was the solution finally.
I use R-wide angles and the Telyt 250 as well as 350 mm together with this adaptor at my D5 and I have no problems concerning sharpness, depth of field and contrast at all.
But one observation is still funny, perhaps some one can help me.
The problem is, that especially using R-lenses at closer f-stops (f/8 to f/16) the exposure time proposed by the D5 always leads to exposures far too bright, and vice versa at f-stops wider open (f/5.6, f/4) they are too dark. Perhaps someone may have a hint to solve this problem?
In the moment, i decided to take shots with 'trial and error', this might be done for landscapes and stills, but for shots which never will be done again this is no way at all. Can anybody tell me some hints? Thank you.
Regards, Jo.
