I realised that people with the exact same setup tend to have a different amount of vig.
For me, I have to crop my fisheye footage in order to make it look more mk1-esque (raw footage screenshot in attachment), but I have already seen clips of the exact same setup (trv900 and baby death 37mm with 52-37mm step-down ring) with less vig than I have (they replied that they didnt zoom in or crop the footage).
Whats the reason for that? PAL vs NTSC trv? shorter step down ring? different baby death (century, opteka, ...)?
Anyone ever noticed that too or has an idea?
