Some things that might be worth to know about the A7C, is the lesser buttons and controls, including no joystick vs the "DSLR" styled bodys.

Also the shutter is EFCS-only, meaning the front curtain is always EFCS and the rear curtain is mechanic. It tops out at 1/4000, which is lower than other Sony bodys. Also EFCS is not so good with bokeh and large aperture primes at high shutter speeds. And the e-shutter has a fairly low read out speed (around 1/30) so not so good with movements. EFCS only can also have banding problems with some flashes when shooting HSS.

On the upside over A7III the A7C has better tracking AF and also have a full Aperture Drive in AF Focus Priority implementation so should be good with low light group portraits with stopped down working apertures, which many other Sony bodys struggle with.

Thanks for you answer. Regarding the shutter I guess you can choose to shoot with the mechanical shutter only or in electronic mode or in EFCS?

Sorry if I wasn't clear enough. The A7C, as also the A1 actually, don't have a mechanical front curtain so you only have the electronic front curtain (EFCS) plus the mechanical rear curtain in the mechanical shutter mode.

The only alternative to that is the full e-shutter, but on the A7C it reads out in about 1/30 seconds so not so good for movement, and not possible to use with flash.

Thanks.
Sorry as I am not a english native speaker

Same here, I'm from Sweden.

, I am not sure to understand everything.
So you don't have the electronic shutter mode only?

It does have full e-shutter.

I do presume (sorry again) that you can shoot in mechanical mode only up to 1/4000s with the rear curtain.

Correct.

But there is no mechanical front curtain on the A7C, so always EFCS.

And 1/160 flash sync speed on A7C, not 1/250 as the other bodys.

And 1/4000 is max with the mechanical shutter on A7C.

So what about photos with a slow shutter (1s - 1/30s) speed you would use for as an example waterfalls etc?

My A7III that has the same sensor can do 30 seconds to 1/8000 with the full e-shutter, but best to check the A7C specs.

I have read the specs of the A7C, the Electronic shutters goes up to 1/8000s? Is that right? That's seems strange really. Probably I missread.

1/8000 is correct. But the read out speed is only about 1/30 so not really good for action.

And I have another question, I see that on Sony cameras you can change the mode from FF to apcs mode, what would be the benefits and disavantages?

If I take a 20mm FF lens, this would give me the equivalent of a 30mm lens? But what about the other advantages and disavantages?
Thanks

On the 24 Mpix bodys the APS-C mode is somewhere around 10 Mpix so I don't use the APS-C mode on those (on the high resolution bodys the APS-C mode is from 18 Mpix and up depending on body and then it becomes useful for me).

When I put my camera in Manual mode, why don't I get any instructions?
