Rolled up the curtain in morning and this view welcomed me in the backyard. As it's December over here in Estonia, the sun really doesn't get any higher or brighter (captured the photo half an hour past mid day).

I went around shopping for the SanDisk 16GB 45MB/s Extreme SDHC Card, definitely lower electronic sound noise in silent videos (and faster reading/writing too) ... bye bye kingston, you'll be in a box from now on for some other silly hobby.

I got it with the same combo of 18-55mm WR + 50-200 WR ... no regrets after running around the fresh snow that came down yesterday :)

focusing in a pretty dark room with the 18-55 lense in live view is pretty snappy after the upgrade, no other side effects noticed.

My view on the issue: i bought the k-30 for it's high iso performance (there is never enough light, except for the cases when there is too much light ... ). The video picture itself of the K-30 is pretty ok for my eyes and i have dreamt of having manual focus in video for a long long time and i enjoy learning how to use it.
With my current understanding of the current design of dslr cameras on the market (lenses and focus points), their autofocus will never be perfect (even look at this canon example https://www.youtube.com/watch?v=dgtbdwsBXE4 ), they are all like a bad joke compared to a real 300$ sony video camera. The behavior there is similar to what i experienced on my previous fuji (s100fs point-and-shoot with continuous autofocus for video) - when you fall off a cliff with focus (go over a house corner or your subject ducks or jumps high), the refocusing is a mess, starts to focus in and out to find the focus again and you lose precious time before a good focus is regained, and if you are unlucky, your subject will move again.
Most of the successful canon af demos are done in a well lit room with narrow focus travel needs. Get outdoors and moving with animals or children and wonky things start to happen. Sadly.
Get used to the manual focus, your common dslr will take a while until a proper AF solution will come.

My kingston card in my K-30 has a whole different problem.
Recording a movie in a completely silent room, holding the camera steady, all sorts of assists turned off ... and i get a thump into the hd video audio channel, about every 2 seconds, with a very precise interval. At first i was suspecting that it's the stabilization, but it isn't, it's exactly in sync with writes to the sd card. On every write to the card (video buffer flushing i guess), some electronic noise is being generated in synchronization with the light emitted from writing to the card (in the lower right part of the camera's back), and that electronic noise makes it to the microphone and gets recorded in the movie. Doesn't really annoy you in noisy videos, but is pretty awkward in silent background shots.
Anyone on kingston class 10 card owners, can you confirm that ? (you need a pretty quiet environment to reproduce). And anybody who has moved to Sandisk - can you confirm that you get the same result or are your videos really completely silent ?
The card i'm using is 16GB Kingston ultimate 100x (class 10) like on this link SD/SDHC/SDXC Flash Cards | Kingston (the blue watery one) ...
