Panasonic vs Olympus EVF

Agreed with others that evf is very personal. I suppose there should be no evf more controversial than that of GX7/85/9. Use field sequential display such that might cause rainbow effect, seasick or even can trigger migraine... Then a 16:9 display unit when shooting in 4:3, total 25% spaces is wasted to make it smaller... It is also of high resolution, and very bright so many complained it, some hated it but including myself, have no problem using it.

I am also a long time spectacle wearer (now half century already) having bad eye sight (myopia, astigmatism and Presbyopia as well). I have no problem on the evfs including that of GX7/85.

A biggest inconvenience so far of those evfs I used to have (G1, LVF2 of GX1, GX7, GX85) are all non OLED. I wish to put on a sunglass since living in a region of abandon sunshine, but all of those evfs are not polarized sunglasses friendly. As I rely heavily on the Live View in evf for exposure setting, only a better than nothing: non polarized and in very light color coating sunglasses be used.

I added a G85 recently, which has OLED EVF/LCD. I am a happy man again. No more black stripes on screen when changing orientations, I can see how the brightness condition will change on Exposure setting...

Try to wear a polarized sunglasses and shoot with the OLED and non OLED display, you should tell the difference.

TBH the larger evf of G85 indeed never gives me a wow factor vs GX7/85 (still shooting them use by side daily). The OLED is the major benefit to me.

BTE, it is a personal preference.
