  • shutter_speeds_table: from EXIF and ProperyCase browser (#264 or #262) at different shutter speeds (nearly the same for different cameras)

Update:

  • Add Support: USB Remote Button
  • Add: Mode Screen Rotated / Flashlight LCD (enable it's in misc and rotate 270 in alt mode) silly mod for test Rotated Screen

I'm very interested to AllBest Build 31 release for the manual focus! Soon on a550...

if someone would add a550 porting to CHDK trunk...it's good thing  :)

What do you mean about "USB Remote Button" I don't know what does it mean, could you explain me?

Any new progress? The manual settings for shutter speed, image distance, and ISO don't work.

One bug is that when I enable the Video mode by the dial, and I push the  ALT button, it doesn't switch to ALT mode, just it keeps switching to Night scene, and then pressing again ALT button, it goes back to Movie mode (obviously also the ALT mode will be enabled, but the mode will be Night Scene, not the Video Mode which is what I want). The only one way to get the ALT menu to show is to enter the play mode and then press the ALT button to switch to ALT mode.

Another bug, when I try to use high quality mode for video (99), I select 640x480x30fps, and when I start recording, the camera shuts down. The High quality (99) works in 320x240x30fps.

I hope I'm clear enough with these bugs.

Barney Fife,

I stand corrected, thank you.

Today I purchased a Patriot Extreme Performance 2GB Read Speed up to 133X Secure Digital SD (PEF2G133SD) and benchmarked it. It seems to be not that different from the old Kingmax 1GB I had before. I think there is a hardware limitation in the IO bandwidth between the SD card reader and the rest of the camera logistics.

So in future I'll just use 3x bitrate mode for video.

I've been looking for manual focus in my A550 for almost a year now, without success. The strange thing is that both in dpreview and in the instruction manual it was stated manual focus IS possible on this device.

So does anyone know a way to do that, without CHDK? Or can CHDK do it, if so, how?

Thank you.

I don't think is possible with original firmware...

...and also impossible with chdk for now.  :(

It's needed implement the last Allbest build with Pseudo MF-mode, it could solve your problem.
