Ok, the EVF vs OVF has been done to death around here. I am not trying to kick start another flame filled debate on the merits of either one. All I wish to do is report my feelings after using an EVF and an OVF camera for the past 8 months.

First a bit about myself so you know where I am coming from. I got my first camera, a Kodak Brownie in the 50s. My first SLR was a Minolta STR-101. I shot a Nikon F2 SLR for 25 years. I switched to digital in 1997 with a Kodak DC-20. I buy a new digital camera at least once a year. I shot Canon for the last five years until I switched to Sony last summer. The two cameras I own are an a55 which I primarily use my 200-500 and my a330 I usually have my 18-55. However I do switch the lenses around from time to time and I use my 75-300 only occasionally. My primary targets are wildlife, specifically birds.

I switch back and forth between OFV and EVF many times during the course of the day. Now I know everyone here is screaming at me that the a330 has one of the worst viewfinders ever created. But there are also many who will claim that the EVF on the a55 is the worst viewfinder ever created. However, I like both viewfinders better that the one that was on my Canon 50D.

Anyway, after using both systems for the last 8 months I am hoping that OVFs will die and be replaced in every DSLR made by every manufacturer. Of course that won't happen. But that is how much I prefer the EVF. My opinion has nothing to do with the optical quality of the image I see in the viewfinder. It is because of the spirit level and the information available on the EVF screens. The first screen is the one I like the best. All it contains is a small square in the middle for focusing (I only use the center focus point) and along the bottom is f stop, aperture, exposure compensation and a little icon for the stabilization.

If I push the display button, which is conveniently located under my thumb it brings up the second screen with the level added. This level is absolutely priceless, especially when used with the Sweep Panorama mode (which is spectacular itself). It makes shooting perfect panoramas almost every time very simple. A second push of the button and you have a whole screen full of useful information overlayed. This includes battery charge information (49%), number of shots left and a GPS icon amongst other things. And I don't have to move my eye away from the viewfinder to either find the button or view the info.

With all this helpful info available I really feel like it is serious downgrade when I switch back to the OVF. As far as tracking moving objects I much prefer the EVF. I shot mainly in burst mode and I much prefer the "slide show effect" over the black-white-black-white effect I get with the OVF, and that includes my 50D. However the "slide show effect" does not hamper my ability to track moving objects.

The bottom line for me is that I will never buy another camera with an OVF.

Tom, did you ever have a camera with a 100% OVF?

That's like wearing shoes 2 sizes too small and then saying shoes are for the birds, barefoot is the only way to go.
 
My own thoughts as well.

I don't miss the OVF at all (my current camera is also the a55), and I very much prefer the additional information available with the EVF.
If OVF went away, I wouldn't mourn.

Good comments.
 
I suppose like all new technology it takes time to get used to it, will be interesting to see what the EVF on the A-77 will be like, good I hope.

"Pru, it's kicking off!"
 
I am not totally in love with the EVF of the A55, there is definitely room for improvement. It bears emphasising though that when I was at the tennis recently I was shooting with the FF canon 5D and the A55 and in two ways the EVF was better. First, I could easily read all the information even though it was a bright day, whereas in the 5D I couldn't see any of the info. Second, because I could see exactly what the WB was doing when the artificial lights were used in the evening. The size of the image was very similar in both, which I didn't really think about much, but I guess it's pretty amazing given the different size of the two cameras.

Roll on the next gen EVF in the A77. Can't wait to see it.
 
I've always been pushing an OVF with a HUD overlay. You could add all the great stuff you mentioned and still have an OVF. It is likely too costly but one can dream :)

My wife just got an A55 so I am hoping to get a lot of first hand experience with the EVF (assuming she lets me use it ;)). My current opinion is that the EVF is quite usable on the A55 and I agree that the level is fantastic especially for someone like myself who can seem to get a straight horizon.

The only downside I can see is so far is that the battery life is less than my OVF cameras but hopefully that will improve in future designs. I am looking forward to the A77.

Yes, I have used a 5D. I have attended several Canon Photography in the Parks workshops in Yellowstone. And for the week long workshop I used a 5D every day just to see if there was any advantage to FF. I still prefer the EVF.

There is a lot of FUD about the "slide show effect". It is caused because the processor is not powerful enough to focus, set the exposure, run a GPS, take 1/3 of a gig of images in 2 seconds AND produce a steady image in the viewfinder at 10 fps. A faster processor will cure the problem. I think that Sony knows this and will make sure the a77 will either have one really screaming processor or two of the current processors. Since this is the first attempt by any manufacturer to use an EVF in a SLR I think they did a very good job and I am positive the EVF in the a77 will be much improved.

I have just recently found a way to dramatically improve battery life. I turn the camera off when I am done shooting a subject while I am looking for my next subject. I have always just left the camera on. It turns back on almost instantly and I turn it back on automatically now when I raise the camera up to my eye, so I am not missing any shots.

My biggest problem with the A33 had something to do with the eye relief or the design of the VF housing, because I had trouble seeing the whole screen with eyeglasses on. Beyond that, though, it was 'tolerable' ... certainly clear benefits, and downsides as well (like the smeary motion blur and the reported issues with tracking moving subjects, which I didn't try), but as far as the "look" it had a hazy look to it, definitely disconnected from the scene.
If I push the display button, which is conveniently located under my thumb it brings up the second screen with the level added. This level is absolutely priceless,
That's probably the one feature I missed most after sending the A33 back. (I tried an A33 and a NEX to choose between them as a 'portable' alternative to the A700, but even with smaller lenses and the fact that I liked the A33 much better, the NEX proved to be the camera I'd take with me more places). The level is awesome, three dimensions, always available, in VF or LCD, in full fast AF LV mode.
The bottom line for me is that I will never buy another camera with an OVF.
I'm waiting to see what the A77 has to offer. I find the technology promising, but want it to be better than the A33/55 before resigning myself to an all-EVF future.

I'm not sure if that's possible, as using the OVF means the main sensor does not get any image, which means a lot of the (live view) information isn't available to begin with.

Like most of us, I read a lot of the threads about the a33 & a55 cameras and look forward to seeing what Sony has in store for us via the "a77". There are two things that I've seen in the last 6-8 months that I think are funny. Predictable, but still funny.

First is that the general disdain and total disgust for all things EVF has gone way down and have been more or less replaced with a high level of acceptance by those that actually use the EVF cameras.

Second is that the brouhaha about ghosting (related to the mirror, not the EVF), smearing and the inability to track moving objects seems to have all gone away.

Despite all of our initial whining last year, the a33 & a55 have proven themselves to be pretty good little mid-level cameras. I hope to buy a new camera next Christmas time and it will probably be an a77, but who knows, perhaps there'll be an a55 MkII to chose from as well

I like it so I wish the one other people like would be done away with entirely.

I finally got to try and A55 and I DIDN'T like it. The view was too artificial for my taste and I really don't need all that information in the VF. That doesn't mean it should be done away with--it just means I'd like a choice.

Isn't that sort of self-fulfilling ? People like the camera they bought because they thought they'd like it ?

Could be it's the non-issue Sony hoped. Could be the ghosts scared away people who shoot subject matter likely to experience the problem.

True enough.

On first glance I admit I thought "oh bit like my old camcorder", quality was low as inside in the shop, but compared to my prior budget SLR its in a completely different league in terms of brightness and usability - I can even tell what apperture and speed I'm on (big problem with Pentax K-r in bright conditions, dim info at bottom of OVF completely unreadable). But yes I get your "artificial" comment if you tried it inside, still rather have bright and slightly artificial than dim. Outside I find its fine.

Nice metaphor! I bet however that Nissan will not abandon the gasoline cars and make electric cars only in the near future!

I don't find my A700 VF dim, it has the information I need in it and is easy to read even for a 67 year old man with rather poor eyesight.
