When a full frame DSLR camera 'shifts gears' into crop frame mode, how does the through the lens view finder show the reduced - cropped - field of view?

Thanks

Edit: I realize that the smaller image circle would show with the FF area vignetted.

It depends on the camera. Everything beyond the DX can be blacked out, or their can be an outline. You may even get to choose.

My Canon 6D doesn’t do this I don’t think.

You can't use the EF-S lenses any way unlike Nikon they can use DX lenses.

👍 I knew I couldn’t use the S lens but though y’all were talking about a camera setting. Had no idea Nikon could use either lens, pretty good deal that you can.

Is there a crop mode on Canon Full Frame DSLR? Please inform me as I don't know about the Canon. On Nikon FX camera which can use the DX lenses and when these lenses are attached they switch into the crop mode that show only the area covers by the DX lenses.

Since Canon Full frame cameras can’t use the EF-S lens I don’t see why they would have that setting. EF-S lens are not of the same quality of EF lens and I can’t see a reason to ever need an S lens anyway.

The FF Pentax K-1 also switches into a crop mode when you mount a crop lens on it

edit: if I understand the review correctly, when the K-1 enters crop mode, it illuminates a frame in the viewfinder delineating the area that will be included in a cropped shot.

Short answer is no.

You would be wrong in that statement. Some EF-S lenses are extremely high quality. Some EF lenses are trash.

I don't quite understand the question. If I put an aps-c lens on my FF A7Rii, the viewfinder will show the same image as if mounted on a aps-c A6000. No outline, vignette or black-out area. Don't DSLR's do the same?

Is your camera a DSLR, with an optical viewfinder? If not, then you're in the same situation that I'm in.

Thanks for your comment

Not clear which brand you have. I can answer for a Sony: when you shift into cropped mode, the image appears larger (as if you were using an ASP-C body), because the camera is only using a portion (cropped) of the sensor; what I see through the VF is the cropped image which fills the VF. By and large, the only real reason to do this is if you have cropped sensor lenses (E-mount in Sony speak) and want to use them on the FF. If you don't go into cropped mode, you're going to get a vignetted image in the VF, as you note.

Yes that is true since you mentioned it, the EF 75-300 kit lens isn’t worth throwing away.
