Fuji X100 series: OVF vs EVF

One of the coolest thing about X100 series camera is that it has two choices for viewfinder, optical viewfinder (OVF) and electronic viewfinder (EVF). With X100T and X100F it goes even further, you can have small screen for checking focus and exposure while on optical viewfinder mode, this feature is called ERF (Electronic Range Finder).

Optical viewfinder and electronic viewfinder has it's own advantages and disadvantages, the optical viewfinder is lag free and noise free because basically you are looking at the real situation in front of your camera.

But with optical viewfinder you can't see the exposure, you have no idea the exposure of the final image would look like, weather it's too bright, too dark or perfectly balance.

Another problem with optical viewfinder is parallax issue, this occurs specially when you are shooting something very close. Because of the viewfinder and the lens are not line up, parallax issue is very common thing in range finder camera.

The electronic viewfinder however, have no parallax issue, so framing is a lot more accurate, plus you can see the exposure very clearly, what you see is what you get.

But the downside of electronic viewfinder is that it can get lag specially on low light situation and also you can see the noise in the viewfinder although it's not appearing on the final image.

If you coming from analog camera (film camera) background you probably use the OVF all the time, that's fine, but if you are a beginner photographer, using the EVF is probably much easier.

Between the optical and electronic which one do you use the most and why? and if you use X100T or X100F do you actually use the ERF mode? i want to know your opinion, please comment down below.
