Sergey LevchinF900 - image warping and motion stuttering

Hello -
I've just run some tests with the F900, and came up against two problems:

1) straight lines warping (mild fisheye) - i believe this is a lens problem (using Canon HJ 21x7.5 KLL), but would love to hear if otherwise: please look at the two images here.

2) motion "stutter" - especially over bright backgrounds: please take a look at this very short clip: when the boy moves his head back the left side of his face strobes or "stutters." (I don't mean the horizontal image breaks - that is of course a compression artifact) what i'm wondering about is the edge of the face "stutter" - and i see the same problem when i play back the tape on an HDCAM deck. i am shooting at 23.98PsF

also, i'd love to hear/read a general comparison between shooting at 23.98 and 29.97 on the F900.

any and all ideas/suggestions welcomed
looking forward
s
