When using a Sony E mount apsc lens on a Sony FF camera, what do you see in the EVF? Im trying to understand will the EVF have blacked out portion or does it compensate and still have full view?

I hope this question makes sense to another Sony user
Thank you in advance

You see what you see just like in a dslr

Yes, you see the full field of view. I have not done testing to see what the change is, if for example you take a FF shot at 70mm and aps-c shot at 70. My understanding is the sensor is not completely used in the aps-c case. Attached is a picture of a shot taken with an aps-c lens and ff a7m3 camera.

According to Freidman's book, the A7R3 will cut back to about 17 megapixels on the sensor and show it full size. There is a "switch" that allows you to turn off the automatic reduction and show the reduced size in the screen or viewfinder. It is a vignette type of view. Mine is set for automatic switching.

If the APS-C lens is a Sony and the camera is set to auto it should automatically switch to crop mode - no black vignette - in the capture or EVF. If it is a non Sony lens you may have to go into the menu and set it to crop mode manually.
You also have the option to set it to no crop mode which will show the black vignette. The vignette is pretty hard so you won't gain anything by trying to fade it in post unless you want to try a square format or something.

You can turn off this autocrop mode in the menu of your FF Sony and use the APS-C lens at fullframe megapixels, filling the screen, with some vignette.

But some APS-C lenses can still be used without vignette at fullframe and full megapixels on your FF Sony. . One case in point: my 10-18mm f4 APS-C lens on my FF A7RIII and A7III. As long as I use this lens at 12mm-16mm on my FF camera, I get full coverage with no vignette, and at full megapixels of my FF cameras (with autocrop turned off in camera menu). .

To test this out, I shot a photo with defined edges with a 28mm ff lens on a a7III. Then switched lenses to a 24mm aps-c. First I shot with auto 35mm on and then off. Both shots were the same and both of them took in much less scenery than the ff 28mm. So the results of the test is that the aps-c lens only will provide a aps-c field of view no matter what the setttings even if used on the ff camera. If the aps-c actually was shooting ff, then the scenery would have increased to a 24mm field of view.

For this reason, I am going to sell the aps-c lens as I want the full effect of a ff lens on the a7III.

Thank you all for your response.
What I’m doing is going from Nikon to Sony
D5 to A9 all ready have
D500 to ??? Thinking A73 or A7r3
But wanted to use the 42meg pixie at apsc so closer to 20

Yes, that will be the result. When I shot on the ff a7x with an aps-c lens, it cuts the raw pixels in half. I would go for the a7III which is what I did. I could not be happier. I looked at the results of a guy on my China trip with a 42mp sensor, and my a7III with 24mp sensor and would not trade!

Certain lens designs allow for enough coverage for an APS-C lens to cover the fullframe sensor, most do not. However the Sony APS-C 10-18mm wide angle zoom has a lens design that transmits a wide-enough image to cover my FF sensor of my A7RIII and A7III as long as I only use it from 12-16mm. I get vignette if I try to use it fullframe at 10mm or 18mm, but get NO vignette using it between 12-16mm, and I am getting a full 12-16mm image fullframe. And with the crop mode turned off in my menus I am getting fullframe 42 megapixel shot with my A7RIII and fullframe 24 megapixel shot with my A7III. Trust me this works with this one lens. I dont know of any other Sony APS-C wide zoom that can do this. This lens and its ability is used by myself and many wedding shooters for large group shots without the expense of the pricey fullframe Sony 12-24mm lens. Cheers

Some Sony FF cameras have a selectable “crop mode” option in the menu. If you have that and choose it your EVF and sensor go into crop mode, showing and recording the aps-c frame.

I can answer my own question. I’m as of today the owner of the Sony a7riii in the menu system page 1 camera menu 1 under super 35mm manuals set to apsc and the EVF shows what is captured is a word awesome!
So hello Sony goodbye Nikon after 57 years of ownership

Welcome to the mirrorless world, enjoy. That Sony A7RIII is a super camera, I have one and love it. Cheers
