I 'bumped' into an adhoc Panasonic trade show yesterday and had a chance to play a bit with the Gh2 and G3 (previously I had seen the GH1 briefly).



For some reason I couldn't figure out if these two cameras had the same evf; but I tilted towards preferring gh2; but to be honest I did not fall in love with either of them (perhaps there are more adjustments that can be made). The colors seemed a bit off and they did not handle high dynamic range very well (the show was setup in a shopping mall with a couple of bright windows).

-

Most of the focus was on tvs et all; it took them a few minutes to show me how to turn on the evf (which were switched off) and the lady had a leica 25 in her bag but didn't know what it was (pity she didn't give it to me as a trinket <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />).

Anyways having seen the gh2/g3 evf (are they identical?); does anyone know how the nex7/e-m5 evf compare with regards to image size; resolution, dynamic range, colour accuracy ?

I haven't much experience with them yet but I have peeked through the VF-2 & G1,G3 evf a while ago.



One notable difference between the VF-2 & panasonics are that the VF-2 is pretty much a mini lcd (the image is built with a conventional rgb pixel matrix) while the panasonic are field sequential.



"Large, bright electronic viewfinder (1.4x magnification, 0.7x FF equiv). The viewfinder uses a field sequential system that mixes red, green and blue images shown sequentially at 60fps, giving an effective viewfinder resolution of 1.4 million dots at 180 fps. "



So you achieve, on paper, the same resolution than Olympus.



This in effect gives the colour tearing "rainbow effect" when moving about. I do remember this effect and not liking these finders so much but they do the job most of the time and their size was decent IIRC (they are larger than Olympus 0.71 vs 0.58). I preferred the VF-2 but was completely turned off by its huge size for a clip on accessory.



Can't comment on the Sony's, but they're said to be a good notch above : large view, not sequential, higher resolution. I'm glad I haven't tried any yet. It would be painful <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />.

Will do for sure but I don't expect any breakthrough as it's basically the VF-2 electronics with improved optics & faster refresh rates.
