CAMERA-SPECIFIC NOTES:
If you need to upload the video footage to YouTube SOOC, use +2 on the in-camera SHARPNESS.
If you're planning on adding sharpening in post-production, then use +1 on the in-camera SHARPNESS.

CAMERA-SPECIFIC NOTES:
After first testing this lens on the Panasonic GH4 (and writing most of the notes in the "LENS-SPECIFIC NOTES" section below) I was amazed at how much better this lens looked on the Panasonic G85 sensor! I was able to cover up that "glowy, purple fringing" easier, and it was much easier to make the color turn out looking "REAL" (the NATURAL profile in the GH4 is not super neutral, but the CINELIKE D is a lot worse). I like using this lens on the G85, and I highly recommend it...though it still does have some "character" (the purple glows are still there, somewhere).

LENS-SPECIFIC NOTES:
I will say this lens has really nice bokeh (out of focus areas) yet the glowy, purple fringing (or chromatic aberration) is very noticeable on light-colored subjects, and it shows up as mystery purple patches all over. If you WANT that effect, this is a good lens for that, but 'm trying to find lenses that retain what I call a "sense of reality" so this one isn't high on my list. In terms of overall usefulness, the push-pull zoom is surprisingly easy to use even for video, as it sort of sticks in whatever position you set it because it has an angular groove in the motion travel that keeps it from slipping too much. The copy I have was a little bit loose, but that made it fast to focus or zoom with (which I liked). I'm not going to comment much on the corrections I performed, because the lens differs so much from one aperture value and focal length to another. Let's just say "It has character" and is full of lots of surprises. In comparison to the older Vivitar Series 1 70-210 f/3.5, I prefer the optics of the older one, but the ergonomics (zoom and focus feel) of this newer one are better.
