This afternoon I went to my local Unique Photo in Fairfield NJ. I went there hoping to play with the E-M1 and the GX7. Finding an E-M10 there in stock was a pleasant surprise. Till now I was mainly looking at the GX7 and the E-M10. But the E-M1 did not feel too big compared to the E-M10 and the GX7. The E-M1 I was playing with at the store had the new 12-40mm lens mounted. While playing around with the E-M1 I noticed that the EVF would freeze momentarily for a split second while panning the camera around the store. I did not encountered any issues like these on the E-M10, the GX7 or the Fuji X-T1 which I also tried, The E-M1's viewfinder is large and bright but while the EVF on the E-M10 is smaller it was no no slouch either. But I'm very concern about this issue I encountered on this E-M1 since I have not read anything on line about any EVF issues like this. I also tried the E-M1 with the Olympus 40-150 which was mounted on the E-M10 and the E-M1's EVF also kept freezing momentarily while panning inside the store. Is this a defective EVF? Like I said I did not encounter any issues like these with the other cameras I tried in the store.
