Here's my report.
Last year, I built another model: an automatic warehouse
, but I used a Canon IXUS 85IS camera for the videos.
This year, I took the opportunity to test the video feature of my Pentax K-7.
The K-7 is heavier to handle, so it was placed on a tripod.
Sure, the industrial line model wasn't the easiest example, because it's mainly macro and the DOF is rather narrow.
The lack of continuous AF during the shooting is the main difficulty. I tried manual AF, but adjusting the AF is a real challenge
and LiveView doesn't help so much
AF is set on pressing the AF button close to LiveView: focusing is obtained by phase detection, which is rather slow.
Contrary to my previous videos edited with Windows Media Maker, I tried iMovie '09 on my Mac.
I found iMovie more difficult to use than the Windows utility.
Windows Media Maker clearly shows the different steps of process: import roughs, select parts, insert titles and transitions, export.
iMovie is rather messy and much screen real estate is lost by the roughs displayed even during editing or title inserting.
Check by yourself!
In the last sequence, I tried to following the white cylinder with manual focusing.
May I say I'm not that happy with the whole process?
For me, the main question is about continuous AF during shooting. It's the main issue which makes the Pentax K-7 video feature difficult to use.
Could a firmware update bring this feature
