I'm happy with Aperture, though wouldn't mind if they keep update it as they do. Use it with Nik software ( a lot) and sometimes with Olympus viewer. Did use LR when on Windows. Is also very good, but for what I do with it Aperture is just fine. Hope for the LR users that they won't put it in the cloud. . . .
The VF-4 is great, even on my E-P2.
Geir Ove: No Built In EVF - No Buy. Even my Minolta A1 from 2003 managed to have a BUILT IN EVF...
I've kept my E-P2 and finished it with the VF-4. Made me happy!
Aleo Veuliah: It is a good upgrade, many improvements, this way LightRoom continue to be the best, in my opinion Capture One the second and the third is the very good RawTherapy for FREE on windows also, and the fourth is Bibble Pro
Well done Adobe
Thanks for the "Photivo tip". Looks like I found what I was looking for. Thanks again.
