For this query im having quite abit of trouble phrasing what im trying to get at so please bear with me. I was taking a look at whether upgrading to FF was practical for my own personal usage but i stumbled across this dilemma. What id like to know is that does the fovcf have any effect on the perspective of an image thats taken, taking into consideration to use different focal lengths to counter the effect of 1.6fovcf.
Eg, 5dmkII+80mm and a 7D+50mm (assuming the physical discrepancies of the lenses are close to identical. Barrel distortion/Pincushioning etc), i presume that distance required to frame a subject identically in each case will equate to the same distance that the camera would have to be away from the subject. Eg ~5m to frame a face only portrait of a person. Correct me if im wrong.
The other thing is the difference in the final picture for either setup considering the main subject has been framed nearly identically in both cases. Assuming the same resolution is used, and the point of focus is the same, are the angle of lines in the picture any different? Or is there any inclusion/exclusion of elements in the picture? (eg. stray tree branches in the background barely getting into the frame). This is assuming that both lenses exhibit similar physical discrepancies in the lens designs such as barrel distortion/pincushion. (Unlikely but just too simplify things)
I know this question might have been rearing its head time and time again. But even after googleing i still could not come up with any substantial assumptions to put this curiosity to rest. I would love to try out an experiment with both cams but alas i have not the funds to own that much equipment. :sweatsm:
