Detailed abstracts when they are done as well as this are far more satisfying than record shots of the whole vehicle. Excellent set.

I agree
+1 on that. *very* nice set.

if it's the orange light on the back, then it might be because it's thinking. If it's anywhere else, then it should not be happening. Which firmware?

Is lens correction turned off?

we don't have a landline at home, so there are three mobiles here.
I don't have a landline at work, so there's one from there, too. They pay for it and a chunk of my communication costs. I call the better part of 5 hours a month.

Lots of internet usage on my part, my wife uses her phone more than I use mine. My daughter doesn't really understand what landlines are. She's 9.

it's a canon 17-55, no close focus, so there's nowhere near 1:1; max magnification according to the stats is 0,17.

I disagree based on practice; focus gets far more critical with Video because you regularly shoot as wide as the lens will go, meaning you have a front of eye in focus and not the back.
With wider focus length you often have less magnification so more DOF right???
Also since the video is a dynamic image (moving) you can't see the finer details so it appears faster sharp then with stills.
doesn't necessarily work like that as clearly as you'd think. See http://www.youtube.com/fsecurenews --> the root video is shot with a 7D and 17-55/2.8. I'm sure f4 is normally in use.

you can..... really, we're normally running at f4 and at shorter distances the lack of DoF is astounding.

If you want to be able to accurately re-focus in one continuous shot then either a follow focus, monitor, or better still, both, become nearly essential. I don't like it and I didn't believe it until I saw it and experienced it in real life. Sunshades are then a necessary evil, as is a rig.

no, it won't, because the resolution of the rear screen becomes the limiting factor and it's only 920k dots. So that's 300k pix - meaning we're talking about 200x150 real life res. Which is pathetic.

Good loupes are expensive (see Z-Finder) or fall off regularly - the only half-decent one that's not several hundred dollars is the hoodman, IMO.

Alternative? arm and 10" TFT in native 1024x576 res (set the HDMI output in the menus to 576p).

you can set it to zoom in when focussing and then start the shot...that's why follow focuses have white skirts to mark focus points.....

the manual lenses are really easy to focus smoothly even without a rig and follow-focus - I saw how shocked my boss was when he saw a section of movie from my M-135 with refocussing as it was extremely easy.
The 28 is also extremely good.
However, no, you can't always get away without refocussing.
