Do you have any examples of a video using any of these lenses? They sound awesome,and great value. Would like to see the effect of the flare in a positive way, and also the general tone some of these lenses give. Have you ever needed a faster aperture than any of the lenses your currently using?
if you want to look at sharpness, check this one:http://www.vimeo.com/19406576
on the right panel you'll find other videos of mine, many of them done with these lenses, BUT don't judge sharpness by any of those other videos, I was making a few mistakes
* used an ND fader, which softens the image big time compared to my current tiffen screw-ins, specially on longer lenses
* shot with picture profile with minimum sharpness and forgot to add sharpness in post in the uploaded version of "roman holiday"; I should upload the final version someday... (edit: I forgot: this one is done with the kit lens anyway)
* I'm just a newbie and still not very good pulling focus... (this also applies to "brown vs. green")
so look at "brown vs green" for sharpness, and "paella in colinas" for colors and contrast directly out of the camera (shooting with picture profile with minimum contrast) and that thing which I call "beautiful flaring"
If you use the same aperture is there a difference in DoF between a APS-C and a FF sensor - I know there is a big difference for stills but DSLR film uses just part of the sensor?
unless you're using the crop mode / digital zoom, you're using all the sensor, so depth of field is the same for stills and video
to get equivalent full frame DoF, multiply your aperture by the crop factor, just as you do with focal lenght
for example, you get the same field of view and depth of field with:
* full frame, 50mm, f/2.8
* APS-C, 30mm, f/1.8
