Lens flare is something you either love or hate. People who love it seek it out and purposefully include it in their images. People who hate it use a lens hood. Lens flare occurs when there is a light source in front of the lens that is much brighter than the rest of the scene (such as the sun).
The lens on the X100F is “Super EBC” (Electron Beam Coating), which is a fancy way to say that Fuji uses a crazy-looking machine that has a vacuum chamber and electron gun to apply 11 layers of coating onto the lens. This coating is supposed to minimize lens flare.

Looking At The Sun – South Weber, UT – Fujifilm X100F – ghosting flare
I loved pairing my old Fujifilm X-E1 with vintage glass. Modern lenses are great, but in their precision they lack character. It’s the flaws that make a lens unique, that give your pictures that extra something that new glass simply cannot.

Orange Leaves – Lehi, UT – Fujifilm X100F – veiling flare
One complaint that I had read about the X100F prior to purchasing it is lens flare. There are some people who think it flares too much and that it’s kind of weird looking (not the typical lens flare that one would expect). An easy fix is a lens hood, but that makes the camera much less pocket-sized.

Tricycle In The Woods – South Weber, UT – Fujifilm X-E1 & Helios 44-2 – veiling flare
I can definitely see why people might not like how the X100F handles lens flare, but I actually appreciate it. It reminds me a lot of how the Russian-made Helios 44-2 renders lens flare. It’s a flaw, no doubt, but it gives photographs character. It’s an unexpected uniqueness. It’s not so cold and clinical and precise. It’s almost as if Fujifilm attached a vintage lens to the front of the camera (except they didn’t). So I like it. You might not, and that’s OK.
I would love to know if the x100v handles the veiling flare issue better? To me this is one of the major drawbacks with x100f
It’s a little different, but not all that much dissimilar. I’d say it’s not quite as “bad” on the new model. If you don’t like it on the X100F, you’re most likely not going to like it on the X100V, either, that’s just my thoughts.
