Did Minolta screw up with the EVF focusing adjustment?

They did their diopter -5.0 to +.5

When looking through the EVF (or LCD for that matter), Images no matter what distance - even at infinity - will be viewed by close-focusing like reading material. Why then does Minolta have long distance correction? It would seem to me that the adjustment should have been +5.0 to -.5 instead of -5.0 to +.5.

Or am I missing something?

0 would be a setting of infinity. When set at 0, the viewfinder will appear to be at infinity.

Well, I don't know Bryan...I have 20/15 20/13 vision with glasses and I can't get the EVF to focus regardless of thet diopter setting. Taking off my glasses and pulling back, I can see the focus (of the small portion that is visible) clearly. So it can't be infinity. Do you wear glasses? Could mine be defective or in backwards? Not likely but...

Hi Rick,

Yes, I wear glasses, but I'm nearsighted not farsighted so my observations may not apply. My perscription is about -7. Surprisingly , I can still focus the D7 pretty well without my glasses, but I always use my glasses with it. I have continuous lens bifocals, and I use the top part of the lens to use the D7. I'm pretty sure that my D7 viewfinder is set at "infinity" an can move back and forth between the viewfinder and a distant object without focusing my eyes. Bryan

Hi Bryan,
I wear glasses and I'm nearsighted too (-1.75 or -2).

I have a problem to see the corners of the EVF (even when I'm not wearing the glasses and my eye is as close as possible to the ocular lens).
There is a vignette effect caused by the ring around the ocular lens.

When I adjust the diopter to + -0 I can see the corners but for my naked eye unacceptable out of focus.

Is this normal? Are there any tricks to adjust the diopter? I'm afraid Minolta desingned the dimensions of the lens for normal sighted people and its diameter is a little bit to small. The ocular lens of Sony's F707 seem to be much better (it's rectangular shaped), you can see the complete EFV even without touching the rubber eye cup with your glasses. I'm a little bit disappointed...

Another thing I remarked:

The color saturation and contrast (or gamma) of the EFV are much higher than the display on the LCD (and on PC-Monitor). It looks unnatural and it is difficult to decide whether the color of your recorded image is OK or not. I know you can adjust brightness of EVF and LCD seperately.
Is it possible to adjust color saturation and contrast of the EFV display?
Some undocumented or hidden menus (almost all new TVs has such menus)?

I guess, the field of view isn't great. I have a hard time seeing the whole thing with my glasses on. Fortunately they are small and close to my face. The EVF does appear more saturated than the actual view; you just have to get used to what it is showing you. Mine is too "warm". Not possible to adjust anything that I know of. Bryan

I'm nearsighted and use the EVF with glasses. My wife only wears glasses when driving and we both use the same adjustment fine.

We both hated the EVF in the Sony, because we felt we were SEEING the EVF, as opposed to looking at a scene thru the EVF.

Obviously, it's all optical fakery, IMO, Minolta pulls it off much better. But it's just one of those things that varies from user to user.[/B]
