Would it be possible to make a 36×36 mm "full frame" sensor?

Is it possible and why it has not been done yet ? Not necessarily. A 24x36mm sensor will easily fit in an image circle that's too small for a 36x36mm sensor. Specifically, a 24x36mm sensor requires a ...

What is the difference between medium format and 35mm amateur photography?

There's quite a bit of difference, actually. Size of the Negative Medium format is a somewhat encompassing term. When one talks about 35mm (135 film), it's most often a camera that shoots a ...

What are the advantages of using TLRs to rangefinders?

The rangefinder only supports framing (with parallax), the dual-lens reflex also supports focussing. This assumes that both lenses move in tandem, and that the picture through the upper lens is viewed ...

Which 645 film-camera produces distinctive rectangular-shaped notches in the negative margins?

I don't think you can determine what specific camera left the observed notches, because it's not a feature or property of the camera's construction. Rather, it's a part of the construction of the film ...

Would it be possible to make a 36×36 mm "full frame" sensor?

The sensors could be made to a square format (though the current diameter would not accommodate 36x36mm, it would need to be about 30mm) if there was a demand for it. But by that logic the question ...

What is the difference between medium format and 35mm amateur photography?

The main advantage these days is that most SLRs and rangefinders are typically for 35mm film, while TLRs typically use 120 film (medium format). Bigger film is much like a bigger sensor: more image ...
