    Posted: 27 December 2020 at 18:19
Hi, all.
I often take pictures at dusk, mostly with APS-C cameras (A58 and Nex-6) as I am usually taking the camera with me on a shopping trip and don't want to carry a lot of gear around. I'm continually impressed by their ability to take usable pictures in dark seaside scenes with a few streetlight reflections in the water, even hand-held, but the actual image through the EVF is often so noisy that I only know how the image is framed when I look at the image I've taken ...

Now obviously an FF sensor will collect more light from a given lens than an APS-C one, so changing to FF would presumably help this, but ...

1) Do the recent E-mount cameras show any less EVF noise at low light than older A-mount ones? Subjectively the A58 seems a lot worse than the Nex-6.

2) Is there any camera setting which will reduce EVF noise while taking a picture?

3) Does it make much difference which FF E-mount camera I choose for low light? I appreciate that the A7S has fewer larger pixels, but can you not get the same effect from an A7 by reducing the resolution? And given that the EVF resolution is already a lot less than the sensor resolution, does the number and size of the pixels make any difference to the EVF/LCD image at low light?

Just to make it clear - I can always carry a small tripod and take a time exposure if I need to (I usually don't with an F2 lens), so absolute sensor noise is not the main issue. What bothers me is the noise I see in the EVF or LCD.

Miranda F & Sensorex, Sony A7Rii, A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras ...

Newer is better. In general, because of sensor and viewfinder. Did a quick try with a couple of cameras, from bad to good:
Sony A6000
Sony A77m2
Sony A7r2
Sony A6400
Sony A7r4
Canon EOS R

The Canon has much less noise then the Sony A7r4.

I am copying some of my response from the other thread.

The Sony R models have lower quality live-view feeds than the APS-C cameras because they line skip more. Their full-frame video quality is also lower for the same reason. The S models have the best quality live-view. The A7III live view is pretty good.


I am not sure how the APS-C cameras compare to each other. The 20 MP sensors do a lot of line-skipping--just slow readouts. The older 24 MP cameras had limited dynamic range and would block up shadows.

The Sony EVF's have been a disappointment to me. for night shooting I prefer an OVF or an Olympus EVF.

Did you test? As my A7r4 is better then my A6400. To me, they're both fine. I can even live with the A6000.

Thanks, Addy. Is this without lenses attached?
I wonder if any other settings matter eg, setting effect, DRO?
