Do you know what the more functionality is??
Charles, an electronic viewfinder works very differently from an optical viewfinder. As John above explained, when you are looking through an optical viewfinder in a DSRL you are basically looking straight trough the lens and thus seeing the world as it is, in real time. The actual image is reflected in the mirror but that happens instantaneously, so you are seeing the world one-on-one.
An electronic viewfinder shows you a projection of the scene. It's like looking at a mini tv screen as it were. And it shows you the image that you are about to take fully processed by the camera. That means you can see if it will be exposed correctly with the present settings. It also means you have a histogram. On a DSLR this information can only be obtained after the image has been taken. With a mirrorless camera the EVF shows you this before you take the image.
And it has more benefits, like focus peaking, which is particularly handy for macro work.
And maybe there are more advantages, but I'm not really the one to tell you about EVFs as I have no real world experience with them. Except checking them out in the shop the other day.

Levina I'm not really understanding here, can you describe the lag please?
do you mean like the frame update rate isn't fast enough so the viewfinder view isn't updated quick enough? or is what you see not quite in sync with real-time?
Joeseph, I checked out three mirrorless cameras in the shop: an EOS R, an M50 and a Sony a7III. And I felt with all three EVFs that they weren't in sync with real time. They were all just a tiny bit lagging behind. Not much, sure, but quite noticeable.

Hi Levina,
good points on evf's. I've been shooting mirrorless Fuji's and a leica Q. the evf's have significantly improved - year after year. once upon a time, I had the Canon M3 and what lenses canon offered (not much) - its EF/EF-S to EF-M adapter was (imho) an awkward adaptive arrangement - which I never used beyond the ef-s 24mm and ef 40mm and maybe the 50/1.8 stm. also, the evf - on the Canon M3 - was an external accessory which one mounted to the hotshoe (meh?). I sold the ef-m system a couple years ago - after I had added Fujifilm bodies. haven't missed it.
meanwhile, in general, evf's allow one to compose accurately. the effects on one's composed image from changes in ISO, aperture and shutter speed (white balance, etc.) appear BEFORE taking the shot in the EVF. also, menus and info normally found on the LCD appear in the EVF (don't have to remove your eye from the finder - to adjust settings). finally, one can review an image - after the shot - without chimping on the rear LCD - as the image can be viewed in the EVF. modern Leicas are now available with no rear LCD. definitely more $ for less clutter. many photogs love them - though group gropes around the EVF get crowded - as multiple eyeballs at the EVF are a bit cozy/crowded. meanwhile - on good bodies - the lag time has been significantly reduced - to the point of it no longer being much of an issue - as it was in the initial EVF's.
combine EVF performance with IBIS and there are real technology benefits to modern mirrorless bodies. in my mind, the current - first generation - CaNikons are basically beta-ware. the Canon R bodies still lack IBIS. more and more, I use modern and vintage manual focus glass (adapted or native zeiss, voigtlanders, legacy nikkors, etc.). so I view IBIS as more than a nice option, especially combined with a good evf.
good luck to the OP. as a former admirer of the 60D (I went through 2 of them), I'll watch the 90D for about 6 months and probably add one - and sell the 7D2 - which looks like it's being fazed out.

Hi Dale,
I'm sure EVFs have greatly improved over time and those that have used mirrorless cameras have seen those improvements can see the advancement. Of course. But all I can speak of is my own experience of looking through an EVF for the first time ever, a few weeks ago, in the shop. The lag in the EVF was unmistakeable. The cameras I tried out were the EOS R, Canon M50 and the Sony a7III and they all had it. And the projection in the EVFs itself was, I don't know, rather bad. Stuttery like. I was actually reminded of old VHS tapes. A world apart from an optical viewfinder with its real time clarity.
I'm sure one could get used to an EVF though. Especially since it does have some advantages over an OVF. But those advantages for me are substantially less important than the quality of the viewfinder itself. So I'm staying with DSRLs for now.
