Not sure what you mean by viewfinder LCD. Do note the different, Canon viewfinder or viewfinder of all DSLR are basically optical viewfinder, the viewfinder found on Olympus camera such as the EM5, EM10 and EM1 are all digital viewfinder... and there will be a slight lag (even my EM5 experience that) after taking the photo, optical viewfinder will not experience such lag, although to be true... I don't really find the lag that annoying.
Thanks rhino123!
For viewfinder LCD, I mean the digital viewfinder scope (thought its a mini LCD inside the viewfinder scope).
I was testing the digital viewfinder scope at AMK but didn't feel the lag. :lovegrin:
