why has no one else ever discussed this before shooting portrait framing 🤔 wont be posting on DPR it wouldn't go down very well.

What is rolling shutter? 😇
-
Love it
but...
Doesn't count - you weren't in silent shutter mode... 😂
-
Now take a cat running up the shutters 😂

Can you take same image without panning? It would be interesting to see, how much horisontal compression is applied while panning.
-
theres is none, ive tried it. ive been searching the net extensively and no one has discussed this. i panned the camera so fast beyond any situation in the real world.
the camera shop guy was so right that a square open gate sensor would be amazing even for stills. -
I wanna see. Compression (or expansion) should occur, it just may not be easily noticeable. You have to measure fence height and rails width and so on.
-
try it on your camera ,it will be the same.
-
You hiding something? :)
Well, measuring distances on your images (one slanted, another straight) gives about 6% of horisontal compression on second. Due to the distortion precision is low, +/- 2% or so. -
not from my measurements . dpr have removed a post on the subject. said they would try and hide it. link not found 🤨

His choice of subject matter and panning speed is one where horizontal compression/expansion would be least noticeable. With a known face, or what is supposed to be a square or circle, the effect will be more visible. With 800mm and a 16ms rolling shutter FF, I get unequally spaced horizontal repeating lines in landscape mode just from the slight vertical sway of the lens during the roll, without panning. The faster one pans, the more consistent the speed, I think, so unevenly-spaced vertical lines are probably more common with slower pans, which are less consistent due to a lack of inertia and more of a direct control.

i have a net ball with me will give it a test today. better still i have a bike.

🙄 fast pan horizontal in portrait mode = no visible rolling shutter .i posted the images already.
anyway the bike wheel did not compress or elongate. but the landscape pan did as usually and formed a tilted egg shape.
-
conclusion. when panning the is no evidence of rolling shutter in portrait mode. in either the subject or background.
when shooting a car moving fast and not panning there is compression and expansion in portrait mode.so if your shooting video or sports you can shoot in portrait mode following the action with no rolling shutter effects at all.

What about a wheel tat isn't moving? If you pan a moving bicycle in portrait mode, there should be no expansion or compression if you perfectly track the wheel with your pan. It is the wheel of one parked bike while you are panning something else that would compress or expand.
