Video Camera?

I’ve not got a mobile. Bob uses his for videos regularly. And it take much better photos than my camera. It is a multi purpose tool that seems pretty good at most things ( web browsing, fb, messaging. It even makes phone calls)
I’m considering getting one when my camera gives up the will to live. Unfortunately I don’t think that’s to far away.
For video I’d definitely go the mobile route.

My understanding of a "webcam" is its sort of used for real-time filming and streaming through your computer, or something like that! Not sure there's a niche for that in the allotment fraternity

Both the phones you've mentioned don't look cheap, unless I've googled(sorry duckduck'd) the wrong models. If I were you I'd at least try a test video on both?

There seems a heck of a lot of allotment/gardening videos on Youtube.

Even a walk around the plot filming with a talk-over of what is growing and plans for the future would be quite interesting I think?

Comparing mine and other plots layouts would be interesting to me?

I have just spoken to my son who reckons the Samsung would cope easily, so we shall see.

Agreed my comment was directed at "live" videos, trust me I've watch loads of YT videos, most with envy
