I generally try to avoid dSLR shooting. I don't have an issue with the images these cameras make, they're often very appealing, but the ergonomics of the cameras are a complete deal breaker for me.
That said, I seem to have had a number of dSLR shoots come my way recently, and so I've found myself further down the rabbit hole that I ever intended going. I've been testing a set of Asahi Takumar lenses on a Canon T2i today, and come across an issue.
I'm shooting various test subjects with each of the lenses in video mode, Neutral picture style, 23.98fps. At the same time I also take a high resolution still of the same frame. In the stills, the lenses are tack sharp, in the video, they are noticeably soft and exhibit other artefacts, like chromatic aberration.
I'm aware that a T2i hardly represents the cutting edge of modern dSLRs. I'm also aware that there are a number of compromises involved in these cameras shooting video at all, but my question is: Is this a problem with this particular camera, a problem with older/cheaper dSLRs, or a problem with all dSLRs?
