Regarding the Elmarit M 21:
Mine is a pretty old version (about 30 Years??). Yes, it is usable on the A7R but don't expect wonders with this lens. Vignetting and magenta color shift is quite strong in the corners. The raw pic ooc looks pretty bad before correction. That is done in LR with the flat field plugin pretty easy.
To get some sharpness in the outer corners you have to use F8 or F11, but that's normal with that old lens. I had to use the same F-stops on my M8 and i don't think that's due to the infamous corner smearing. Even stopped down the sharpness in the corners is not stellar but from the middle to 2/3 of the frame it is very good.
For general photography with some work in PP the lens will be OK.
A matter of contrast (and contrasty light). Use of ND filter would help out under gloomy skies.Oké, scientificly it can not be, but I seem to remember better files, but as I said it is very hard with the posted subjects to check sharpness in that jungle of branches.
Well here is one with the NEX-7, more sun and closer by, but crisper.
The second one, less light and a little farther away but it looks like nothing really comes in focus
Not very scientific testing but my memory serves me well.
That's what it looks like to me, too. Michiel, what you say is definitely the case in terms of the appearance of the two images. I would be very interested in seeing a side-by-side comparison with this lens and the same adapter on the A7R and the NEX-7, using a tripod.the second one looks to suffer from a little camera shake... or perhaps mirror slap vibrations?
Where is Carlos?You folks are really good have yet to see a cat photo. We are moving up in the world. LOL
