I saw some clips from Tokyo and Sydney at night and they looked very, very sharp. I would say they were full 1920x1080 to look that sharp. As it was all available light I'm thinking low light. Does this happens just in cine mode, this loss of resolution?
Okay, maybe loss of resolution isn't the right techinical term... so this is something for the tech guys to comment on. I just noticed that image was a little less sharp and seemed to not to be "full" as at 1/48. Certainly, that could be just the result of camera movement or plain effects of gain from lack of light, but I think one of the recommendation for anyone shooting 24p in any camera is to shoot at 1/48 to preserve maximum resolution. Someone else will have to give the tech expertise, this is just my feeling after looking a footage.

Re. pulling focus in manual mode, be sure to get familiar with how the "Focus Assist" button on the LCD (the right-most "stop" square) behaves. That's the "manual assist", for lack of a better term, Canon built into the camera to help people out.

Understand that feature, but it doesn't work as you are handholding with a 35 mm adapter and having to pull focus as the subject changes relative position.

When you are using a 35mm adapter you would use the 35mm lens to focus while keeping the hv20 focus locked. under that circumstances does the focus assist be of any use??
Or am I missing something?

Focus assist enlarges a portion of the LCD viewfinder to aid in focusing. This will help, even in focusing with the 35mm adapter. Focus assist should not be confused with the autofocus feature.

Oh? May I ask if that's something you heard from Quyen directly or is it just "rumors"? I'll certainly ask him myself, but from what I've heard, he's a very busy man (not saying you're not, Chris! ;)).

This gives a wide range of adjustments plus or minus in the exposure adjustment slide. Then they half way depress the photo button to assure they haven't gone outside the parameters they were trying to stay in. When I shot the film I did, I had a difficult time staying in 1/48. The darker scenes were in 1/24, and I consequently lost resolution.... Time permitting, I should have added more light, but the schedule was tight...
I have been reading about the cell phone trick etc. Do you have to repeat it every time you turn the camera off or can you store it like in the SD card or something?

Not that I am aware of....

Did a quick test and no, the exposure lock is not preserved/remembered between power cyclings. You have to repeat the trick every time to re-lock/set the exposure.
