Canon 70 200mm f4: Distortion

move on now and look at Distortion and fetting back on a full frame camera at 70 mm we see some noticeable Barrel Distortion and just a little vignetting or darkness in a Corners stop down to f5.6 and they brighten up again zoom in 90 mm and that Distortion straightens out but we see vignetting…

Uh we get a bit of distortion at the wide end and a bit of pincushion at the tele end, but I've not really found them to be too distracting and well, lens corrections simply can get rid of them for me in post editing.

this really is nitpicking for a zoom lens this is brilliant stuff now onto Distortion and fetting these are normally corrected by your camera but you can turn those Corrections off to see the true performance at 70 mm there's a small amount of battel distortion but not very much vignetting at F4…
