vertical lines/ sensor problem?
on Apr 11, 2012 at 2:38:43 pm

Hi all.. im new here i usually just read what people say but for the first time i have to ask a question.

ive had the dslr for about 5-6 months and ive always shot at shutter speed of 50 (im in australia so shooting at 25ps).

(Shooting VIDEO:)
today just to create a sharper look( blur wise) i put the shutter speed to 100 (shooting at 25fps & iso 200) and aperture was wide open.
was shot in a car so wasnt using any lighting other then natrual light, once i brought it home i discovered vertical lines, particular when in dark parts (car seat cover) and when i was moving around his face vertical lines were obvious.

I did a screenshot of the video see below:

not sure if the screenshot is enough but when in video and in that image you can see the vertical lines across his face etc.

also at dark areas:

you can see the vertical lines more obvious here on the car seat.

why is this? is there something wrong with my camera or? im confused.

I noticed this on footage from my t3i. I have no clue what it is. I began to notice this after using a Nikon Nikkor lens with a fotodiox adapter. I wonder if that has anything to do with it.

YOU FORGOT TO PRESS RECORD!
