Help me out here, my mind has gone blank on this. If I shoot a square 120 image with a standard lens, let's say 80mm, and I crop top and bottom to make 3:2 ratio landscape image, have I done the equivalent of putting a wide angle lens on the camera?

No, you've done the equivalent of shooting with a 645 camera. The standard lens for 645 is also 80mm.
No, what all of them said.

Okay, thanks. So I assume that as long as the landscape dimension remains at 60mm, the portrait aspect could be tiny (let's say 10mm), and it would still be a standard 80mm lens shot.
If an image is cropped inside the frame, it's the equivalent of changing the lens for a longer one (I mean field of view equivalent, I know it doesn't have the same optical effects), but if the longest dimension is maintained it will always be the size of the original lens. I had to get my head around why a focal length effect could be longer but never wider.

Is a panoramic image the same as a wide angle image?
Changing focal length changes the relationship between near and far objects. Cropping does not.
Actually, it is only a change in the photographers position that changes the relationship between near and far objects.

All makes sense. A wide angle lens does not neccesarily distort a face -- the nose only seems bigger because one moves in much closer for the same headshot as a longer lens.

I raised the topic because I'm doing more 120 than for a while, and the square is sometimes a help (portraits) and other times a burden (everything else). There seems to be a technical answer and an instinctive one. Technically, a focal length remains the same whatever ratio you print at, but emotionally a long print suggests wideness because it has to be visually scanned.If you want a simple solution, just mark your focusing screen with 3:2 ratio lines. For years I never liked the square format. 30 years ago when I had to decide which 2 1/4 system to go with. It was either Mamiya RZ or Hasselblad. I thought Hasselblad wasn't for me because I'd crop most of the image. I shot with my RZ for decades and as I get older, the thing is getting heavier. How I want a Hassy. I usually compose my shots looking edge to edge and I rarely crop.
