When I first started using the Fujifilm X-Series last summer I didn’t realise how helpful electronic viewfinders (EVFs) can be. Being able to see a live view of the exposure and then adjusting this via the exposure compensation dial means that I am more efficient. When using SLRs it is often difficult to get exposure compensation exactly right the first time around, this often means you take a photograph multiple times to get it just right. With X-Series cameras you are able to see how an exposure adjustment will effect the exposure of the image before you take the photo. This is especially helpful for fleeting moments, especially in quickly changing light.
The exposure compensation can be adjusted in post-production but I feel the live view produced by EVFs has helped me improve my photography. This makes my editing workflow shorter, which is always an advantage.
I found this feature particularly helpful when taking silhouettes, such as the images of Chesterton windmill in the gallery below.
EVFs are also very helpful with non-Fujifilm lenses or using Fujifilm lenses in manual mode as they can accurately show when the focus is correct. Even with the X100s and X-Pro1, which have hybrid viewfinders, I use them almost exclusively in EVF mode instead of OVF mode because, for me, it offers more benefits.
