In a Canon first, they actually improved the camera by adding features in a firmware upgrade! Usually firmware upgrades for Canon (and Nikon, etc.) just addressed bug fixes. This is the first time that I can recall that new features were actually added (including one I actually emailed Canon about adding a year ago) and the performance of the camera has also been improved (max burst rate for all picture types from RAW to JPG).
Here's a link to the page explaining what you get with firmware 2.0
Here's a link to the firmware update page
Just select your OS and click on Firmware and choose 2.0 (don't choose Mountain Lion as it wasn't listed there yet, just choose Lion and you'll see the 2.0 firmware, use that one)
- [*] Max burst rate increased from 15 to 25 for RAW images (and corresponding increases for the other pic types)[*] GPS compatibility with Canon GP-E2[*] Manual audio level adjust (64 settings) so you can set your video recording audio level appropriately (it was fixed before)[*] Set maximum Auto ISO Level from 400 to 6400 (this is the one I asked Canon for, so when you're shooting with Auto ISO setting you can tell the camera to not go above the maximum set ISO[*] In-camera RAW processing (so you can set your white balance, NR, corrections, etc. during playback)[*] In-camera JPEG resizing[*] In-camera picture rating[*] Quick control mode during playback of images (allowing for more pic customization "on the fly")[*] Customization of file names (set the first 3 or 4 letters instead of always having IMG_)[*] Time zone settings[*] Improved/faster scrolling of magnified images[*] Improved compatibility with UDMA7 Compact Flash cards (not on the site but reported elsewhere)
And these are the ones Canon has advertised. Certain Canon user forums are trying to ascertain whether or not there may be actual picture improvements such as better noise handling at higher ISOs, etc. Stay tuned!
I upgraded mine late last night, I'll take some shots this weekend to see if how it performs.
The only minor bummer is that those new in-camera features only work on images you take *after* the upgrade. So my CF card filled with images couldn't be altered by the camera, but every test shot I took last night could.
Happy shooting! And post your experiences here if you do the upgrade!
