I said earlier "Yes distance to subject determines perspective, " it should have been "Yes distance to subject and lens magnification determines perspective," A standard 50mm lens is considered to have no magnification. 100mm = 2X etc.
Tamron also have a simulator which works correctly. You can see the flattened perspective of the long lenses.

If you compare say a 14mm wide angle shot which gives a deep looking perspective to a crop of say what 200mm lens sees the 200mm flattens the perspective, but you won't see it until you enlarge or reduce the original so that both are the same size. Alternatively make A4 prints of both.

Equivalent field of view doesn't make lenses the same - the perspective exaggeration (difference in apparent distance between foreground and background) and DOF will relate to the focal length.
Because you're looking at the middle bit of a 14mm image not the full frame of a 20mm image.
I would have thought these differences in the case of comparing a 14mm versus an 18 or 20 would be significant. I have an APS-C so the comparison I would make would be between the short and long ends of my Sigma 8-16. The differences are about far more than just field of view.

I found a DPReview from a few days ago and it explains it very well.
CHEERS Vic.

For any camera you can use tiny triggers such as FlashQ......

She's well worth a listen and it's not the mike that makes the songs...

Sorry. One came out upside down. Vic.
Seriously all nice shots. Great to see these classics.
