My Take on the Leica MEV-1 Electronic Viewfinder — A Letdown?

I’ve been using the Leica MEV-1 for a while now, and honestly, I’m pretty disappointed. The 60 fps refresh rate feels dated, especially once you’re used to smoother EVFs. Compared to the Q3’s 120 fps, the MEV-1 feels laggy and less responsive.In low light, it’s even worse. The image gets muddy, judging focus and exposure becomes difficult, and it’s just not pleasant to work with. On top of that, the resolution seems surprisingly low — far from what I’d expect at this level.

There’s also a very pronounced banding effect that looks genuinely awful in use. What makes it even more frustrating is that I never experienced anything like this on my Q2 — and that’s a significantly older camera.

So I’m wondering: am I missing some critical settings, or is this simply a weak EVF by today’s standards? Compared to modern Leica bodies like the Q3, the MEV-1 feels clearly behind. Curious if others feel the same or have found ways to improve it.

What you are missing is that this camera is a solution for those who can’t or won’t use the rangefinder but insist on staying within the M system. It is not meant as any kind of challenge to a modern mirrorless camera, it is a variation on the M11 based on the request of a limited group of customers. The EVF is obviously limited by the electronics and CPU that are slanted towards the donor camera and certainly improved over the Visoflex. If it suits your requirements it is an excellent solution, if your expectations are different, well, due diligence rules.

I understand the positioning and the intent behind the camera, and I agree it’s not meant to compete with modern mirrorless systems. That said, being a niche solution doesn’t automatically justify strongly visible banding, poor low-light usability, or an EVF that feels three generations behind.

What makes this harder to reconcile is that the Q2 — which is significantly older — didn’t show these issues at all, so it’s difficult to explain this purely as a “different use case.” Saying it’s not a mirrorless challenger explains the concept, but it doesn’t really address the technical shortcomings that are clearly visible in use.

I’m still genuinely wondering whether there’s some setting I’m overlooking that could improve this, or if this is simply the harsh reality of the MEV-1.

[jaapv]

Banding should not occur, I agree,  but it should not occur on an EVF “three generations behind” either. The problem almost certainly originates in electronics that were not designed for an EVF (or rather only for the less demanding Visoflex) which cannot cope with a more sophisticated demand. I expect/hope that can fix the banding problem in an update. The Q was designed for EVF  from the ground up, a completely different proposition, so a comparison is not very valid.

Got a couple flickering and banding issues with the MEV1 recently. Setting Exposure preview to Off or Shutter Button Half-Pressed did fix the issue apparently. Since then, my MEV1 works as well as does my M11 with Visoflex 2. Still the best mirrorless and rangefinder cameras for M lenses respectively, so nothing new since this thread AFAIC.

You are clearly a target customer. Congratulations.😄

Basically, apart from the viewfinder, we have an M11, so both are identical in terms of quality. The EVF resolution is comparable to that of the Q3/43, with almost 6 MP. I recommend first testing a Q3/43 and changing the refresh rate from 120 to 60; you'll then find there's practically no difference. I don't know to what extent this affects low-light performance. You describe "stripes"—what exactly do you mean by that? Or do you mean the rolling shutter?

I'v been shooting the M EV1 a lot at night, and have not experienced any issues using the EVF in low light, or with 'flickering', or with 'banding'.

The EVF seems on par or better than my Fuji GFX cameras, and feels better than my Q2.

Acquiring focus has been easy with auto zoom + peaking - even shooting wide open at f/2.

How about you post a 'banding' image so we can see what you're problem is?

that‘s right， when focus inside the room， the EVF works just like jam， much worse than the old digital SL2

Thanks for all the replies. Yes, turning off exposure preview or using the shutter button half-pressed can reduce some of the banding, but that’s only because the preview becomes uniformly bright. Even then, the banding is still noticeable, especially when reviewing photos after they’ve been taken.

Disabling exposure preview really defeats the whole purpose of the EVF, since I want to see a realistic preview of what the image will actually look like—otherwise, I might as well just use an M11 😝

This Wikipedia article shows exactly what I’m seeing in the EVF, both in live view and when reviewing images trough the EVF — very similar to the 8-bit gradient example: https://en.wikipedia.org/wiki/Colour_banding

From ISO 64 to 2500 the banding is clearly visible (like 8-bit). Interestingly, from ISO 3200 upward it largely disappears, although ISO-noise becomes very noticeable  at that point. On the rear LCD, however, none of this is an issue — gradients are smooth, colors look rich, blacks are deep, and overall the images look very pleasing.

I can't answer for the MEV1, but I set my Q3 43 to 60Hz, and see no banding. I don't use 120Hz because of the additional power drain, and frankly because 60Hz is just fine for shooting active people in low light. Banding and lag shouldn't occur just because of a reduction from 120 to 60.

Edit. As someone has suggested in another thread, check that you're not viewing in artificial light. Interference effects can cause banding.

Until I can completely understand WHY banding is occurring with some and not others I will not buy the EV1.

Comparing settings and use cases is most important.

While I do not have an M EV1 I am very familiar with banding in my SL bodies.  This occurs only with the electronic shutter in artificial light when using shutter speeds that are not a multiple of the frequency of the lighting. Very rarely I see this with the mechanical shutter, but the electronic shutter does it consistantly.  Since some posters mention that banding is visible when reviewing images, I wonder if some of the banding issues are the result of electronic shutter use.

You mention seeing the banding on image review? - I just looked back through the last 200+ images on my M EV1, using the EVF. Night and daytime shots, ISO from 64 through 6400, zero banding. Just nice clean grads of color/tone as you'd expect. I suspect you have set-up something with the camera that is giving you this issue. Color, contrast, noise reduction, image resolution, etc etc - lots of variables. Do a full camera reset and start again. Before you set anything other than factory default, see if you can still replicate the problem. If you can, return the camera as faulty.

Are you using the electronic shutter? All cameras with the same 60MP sensor will have the same banding with the electronic shutter.

[bcaslis]

This really sounds like electronic shutter with LED lighting. Have you seen this with mechanical shutter? I have not seen this on the EV1.

One would expect to see it in liveview/EVF (plus artificial lighting) as well because the sensor is being read sequentially the same way. But I actually rarely see it in liveview/EVF, only in the recorded image - perhaps it's masked by camera movement?

I feel the Leica M EV1 is a good concept but is lacking better internals that the Q3 and SL3 variants have with the Maestro IV processor, while the M EV1 only has a Maestro III processor. It can only deliver what it has to work with which is a slower refresh rate evf compared to the Q3 and SL3 variants.

OP clearly stated that the images look fine on the LCD  'On the rear LCD, however, none of this is an issue — gradients are smooth, colors look rich, blacks are deep, and overall the images look very pleasing' - so from that, my take away is that the recorded images are fine, with no recorded banding. It' just replay through the EVF where he has an issue. I would assume that rules out electronic shutter as the problem.

Slower refresh rate does not cause banding however - or cause any actual issues in actual use. Faster refresh rate feels more fluid, but doesn't in any way impact image quality
