A real TC will almost always result in a better image, but the problem with a real TC is you have to first have one and you also have to attach it. Digital teleconverter (or Digital Zoom in Panasonic cameras) comes free with the camera and is a button away.

Kind of off topic, but I wish camera manufacturers can try some of the super resolution modes like Google Pixel does. It's similar to but not quite as demanding as HHHR. By using this only tied to digital zoom, it allows the camera to ignore the unused parts of the sensor area and get a faster burst of images.

I had not heard of that. Pretty cool. Do you think the processors in our cameras can handle it? They can do handheld HDR where they merge several photos while aligning them and many other things. This looks like another area that the camera companies should learn from what is being done in smartphones.

For a 2x zoom, it would only be processing 1/4 of the data that something like HHHR does, so it should help a ton on reducing the processing demands. Might make the feature viable in a lot more cameras. The other thing camera makers need to do is much better AI to reduce motion artifacts. That's something current in-camera HDR mode and HHHR generally does a poor job of doing.

Absent of this, having a continuously variable digital zoom would be useful. My Panasonic only comes with 2x or 4x. 4x is a bit too much, 2x works ok, but it would be much nicer to be able to get other values (even less than 2x). For example, if I want something between 140-280mm (on my 14-140mm), the current digital zoom implementation means I'm unnecessarily throwing away 3/4 of my sensor area to achieve that.

I think Olympus just has 2x, but maybe I have missed something. I have the Panasonic GX7II (GX85) and I have not explored this function yet.

I have GX85 and it has 2x and 4x. It's under MENU > [Rec] > [Digital Zoom]. For quick access, this can be assigned to a function button.
