What do people have against EVF...?

I am just interested why so many hate EVF so passionately. Some even talk in terms of EVF compromising image quality.

As I see it, it is a compositional aid where all the decisions about need for filters exposure compensation etc are taken before the eye goes to the VF. Or do people make decisions about the photo based on what they see through the VF?
The alternative in a camera designed for compactness (which is the main selling point of MDT) is the pellicle mirror which has its own limitations regards VF brightness.

I don't know what they are like nowadays but when I had a camera which only had an EVF it was impossible to use it to manually focus and the response was so slow it was difficult tracking a subject.

My D7000 has live view, which I have started using occasionally when the camera is on a low tripod and the ground isn't suitable for getting down to the view/angle finder (rivers etc), but I still much prefer an optical viewfinder.

I have not tried one of the this year ones but the problems I have are simple bias (don't like it in the way I dislike Marmite) and some of them are issues.

So Issues I have seen, problems with update rate so for action and panning type operation it can lag or have longer blanking than the mirror and also tearing of the image. Then as you turn if you go from bright area to dark area you have the auto-gain delay. Also they heat the sensor and reduce battery life. Then you have the impact of the conversion process imposing its colour and brightness onto the scene.

And some items are simple personal bias. I like being drawn into an optical viewer and not being aware of the pixels generating the image. Is that valid, well not for some for others yes. I think they will get there and I expect them to be the choice in the future, but its not my personal choice at the moment. But if you do a lot of video your views will be different. I am happy to review this when I get around to looking for a new camera.

Those that do probably disliked the waist level finders found on twin lens reflexes as well

Why do you think that Paul? The ground glass screen on a TLR was simply a larger version of the ground glass screen you see when you look through the optical viewfinder of a modern dSLR. You will recall that most TLRs had flip-up magnifying lenses in the viewfinder hood. Then, with medium format SLRs like the Mamiya, Hassy and Bronica, etc., you could buy optional extra pentaprism hood that corrected the orientation of the image on the ground glass screen and were, in that sense, the precursor to the modern SLR viewfinder.

What I have really noticed on this forum is the number of correspondents who seem to think that, with a dSLR optical viewfinder, you are viewing straight through the mirror and lens and fail to appreciate that the image in a dSLR viewfinder is a two-dimensional plane image projected on to a ground glass (or similar plastic) screen within their viewfinder housing. As soon as the meaningful resolution of an electronic viewfinder matches the apparent resolution provided by that ground glass screen, then I guess all the objections to EVF will disappear overnight.

Now, what I really hate are the LCD type "viewfinders" such as I have on my Olympus PEN. That really is an abortion that I have thought of augmenting with a rectangular wire viewfinder that I could clip to the top of the camera and thus avoid all optics and electronics.

Its not the EVF particularly, Its the removal of a simple optical VF option, Compounded by some manafacturers then offering an EVF option, As an expensive extra, Where only an LCD is available by default.

If the same companies bothered to fit an optical VF, No one would need to buy the expensive " Add On " EVFs......!!!!!!!!!!

Its just another way of screwing as much money out of the punters as possible.....

Many years ago the european car manafacturers did the same thing, Everything was an extra, Even stuff like door/wing mirrors, Then the Japanese motor industry capitalised on the market by including all the add ons as standard, Seems to me that the camera makers are doing the same thing, But in reverse.....!

My motto, " No Optical Viewfinder " = No Sale, Period, End of discussion....

The only practical objection I have too hem is when attempting to use them in very low light conditions.

When it's really dark, the viewfinder's tend to be black, so you can't see what you're shooting.

At least your being offered a choice, not every one is going to want a viewfinder.

What Vince said, but while I'm at it, there are plenty High Street opticians selling us specs and contact lenses and none selling EVFs to help us see better. Maybe there's a clue in there?
