Shimmering In the EVF?

I am intrigued by the Sony a7rII and went to my local camera shop to put my paws on one. We took one straight out of the box with a new lens and I was surprised by a waviness/shimmering in the EVF It was very distracting and annoying. At first I thought it might be some focus peaking thing, but FP was turned off.

I am a total newbie to this camera. The plug-in eve I have on my Lumix LX5 doesn't shimmer? Whats up? Is this typical? If so, I will be bummed. I am shooting with the said Lumix and a Leica M6 (film) and wanted to find a digital back for my leica glass.

Thanks in advance for sharing your wisdom.
 
Yes it can be there with high contrast images but is less noticeable if you turn the EVF to the high resolution setting. I used to find it annoying but have recently found that this effect can be helpful with the Loxia (or any manual focus) lenses as you can see where the plane of focus is without having to use peaking which I find to be too inaccurate
 
Thank you so much. Next time I am in the shop I will try changing the magnification. The first time I noticed it was high contrast, but the shimmering was still there when I aimed the camera at a pretty solid colored wall.

Question: does changing the magnification, change the field of view?
 
I would also check the AF mode and area, if the AF is continuous and the area wide you can get a slight movement as the af tries to decide the actual subject. Set to AF s and centre spot, this might be the answer. This is the only situation where I find any 'shimmering'
 
it also occurs when sharpness is turned up +3 in the settings. I find it useful when focusing manually as the shimmering occurs around objects in focus. Try turning down sharpness (it does not affect raw just the evf or rear screen image)

Nothing to do with magnification. Go into menu - Suitcase - level 2 - display quality and set to 'high'

Without seeing what you're seeing, I can't be definitive, but there are two possibilities, both related to aliasing.

The first is spatial aliasing, as the finder resolution is low compared with the lens resolution. If that's it, increasing the finder resolution may help.

The second is temporal aliasing, as variations in the lighting (LEDs and fluorescents are both likely to do this) interacts with the scanning of the sensor and the refreshing of the finder. If this is the case, you may see it at quite low frequencies, as the lighting and the refresh beat together and you see the difference frequency. You can tell if this is the problem by going outside and seeing if it occurs under natural light.

This has a big impact on battery life, so weigh it up against that.
 
Also check that Zebra is turned off, as that has a shimmer like effect.
 
OK, at this point I understand the shimmering may be due to resolution, AF mode/area, quality, sharpness, Zebra or peaking. I have no idea what most of these are and I can assure you the salespeople at the store don't know either. Makes me wonder if I am diving into a heap of hurt just to use my leica glass full frame. Is there a guide/book that can help suggesting adjustments and settings on this camera or am I on my own ( with the help of forum members)?

Why don't you make a cellphone video and post it so we can see what you're talking about?

Shoot a video, too. You know what they say about how many words a picture is worth.

BTW, if you have all that Leica glass and love the way your M6 handles, you may want to look at the M240 when you're in the store. I have one, and I consider the a7RII to be better overall with some Leica glass (built in EVF, size, weight, price, resolution, IBIS, focus mag anywhere, etc), but the M240 offers the RF experience, and does better with some Leica lenses:
