PowerShot A590 IS

The Powershot A590 IS is a 8MP camera released in January 2008.

CHDK is available for the A590 with firmware version 1.00E and 1.01B from the Download page

Reviews and Specifications

CHDK features still to be ported to the A590IS

1. Video compression options in CHDK have yet to be unlocked for this camera as of 31/12/2008

Update: 9/14/2010 the compression options seems to work very well now, and I can change the bitrate on the fly while shooting, as well as focus/zoom. The results indicate change in quality, in addition to displayed bitrate while shooting, proving the settings to work.

Technical Data

Digic III image processor
DryOS operating system

Sensor CCD size:	8.0 MP 1/2.5"
Lens (35mm equiv) zoom	35-140, 4x
LCD size	2.5" fixed
Card	SD / SDHC / MMC
Size (mm)	94.3 x 64.7 x 40.8
Weight (body)	175 g

Hardware Limits:*

ISO Range: 80-1600 (Manufacturer)

Aperture: f/2.6 (wide angle) to ~f/11 (full zoom) (f/20 real hardware limit at 140mm)

Shutter speed: 1/2000 to 15" sec (manufacturer -- needs testing for hardware limits). CHDK up to 460 sec reported working [1]

* Note: maximum aperture and ISO speed need to be confirmed by someone else -- acetone

Max ISO confirmed to be 1600 -- deity of chaos

My test: with CHDK i can setting ISO from 64 to 8000 (PaiaCZ)

My test: with CHDK I can go from ISO 16 to 1600, though it shows 8000.(anonymous)

Firmware info

Firmware information is given if ver.req exists on the SD.

In PLAY mode (with ver.req) press FUNCSET and DISP simultaneously:

Canon PowerShot A590 IS
P-ID:3176 NT D

Firmware Ver GM1.01B
NoError
Jan 24 2008 20:41:51

On an A590IS bought from amazon.com in June 2008, the following was observed:

Power on in PLAY mode with ver.req file on SD card, press and hold FUNCSET, press DISP reveals the firmware version:

Canon PowerShot A590 IS
P-ID:3176 NT D

Firmware Ver GM1.00E
NoError
Jan 8 2008 16:57:22

subsequent press of DISP (while still holding FUNCSET) reveals:

Adj Ver.011.002

subsequent press of DISP (while still holding FUNCSET) reveals:

IS Firm Ver. 2.06

IS Param Ver. 2.01

If you power on in PLAY mode without ver.req on the SD card and press the FUNCSET and DISP buttons simultaneously, the screen shows:

Firmware Ver. 1.0.0.0

    [ OK ]

CHDK specialities

Since CHDK changeset #917 the <Alt> button can be set to PRINT (default) or DISPLAY from the "Miscellaneous stuff" / "<ALT> mode button" CHDK menu
- If DISPLAY is selected for <Alt> button: press DISPLAY quickly it will act as your <ALT> mode button, but if you hold it down for a second, it acts like the DISPLAY button normally does
