Things that sound cool:
- 15.1 Mega Pixel - This is a huge update, especially considering the minimal jumps from the 20D to the 40D.
- DIGIC IV - New image processor is always a plus.
- Higher ISO - Up to 12800 ISO which levels the playing field a little with comparison to Nikon and the D300
- Upgraded LCD screen - 920,000 dot/VGA screen means even better resolution for preview and live view. This is especially interesting for me seeing I've always been a bit frustrated with the resolution of the preview screen.
- RAW in creative modes - Though not my style, I like to see that RAW is an option for those people that are still out in the creative modes.
- Improved Live View - Live View was a nifty idea but I never really used it mostly because AF was not very smoothly integrated. With the new Live View features, I'm interested to see if they made AF much easier.
- Illumination Correction - Apparently this feature automatically evens the brightness across image a la a gradient filter. For JPEGs, these changes are written directly to the file. For RAW files, these changes corrected in post-production in RAW with DPP. What scares me is, personally, I wouldn't want the camera deciding where it thinks the line between light and dark is. Adjustments over the entire frame I can live with because you can predict and adjust for what the camera will do. Adjustments across only part of the frame rely heavily on the decisions made by the internal processor on the camera.
- 15.1 Mega Pixel - Shoving more pixels on the same sized sensor sounds like a recipe for noisy pictures.
- Auto Lighting Optimizer - Sounds a bit like they are photoshopping for you, which, for the same reason Illumination Correction scares me, scares me.
- Creative Full Auto settings - An interesting idea but this again feels like auto photoshopping.
- Live View face detection - This feature seems like it doesn't fit in a DSLR. I just can't imagine people holding their huge DSLR out in front of their face like it is a little point and shoot. It really does feel like Canon is trying to make Live View standard way to compose shoots with a digital camera but I just don't see that being feasible with a 2 lbs DSLR that is hopefully strapped to your neck.
- sRAW1 & sRAW2 - I never understood why someone would want to shoot in sRAW. It didn't make any sense to me then and it I don't understand why they would add one more level of sRAW.
- HDMI Output - This seems to be another feature that has been imported from the point and shoot line that really doesn't fit. To me, when I want to show off my pictures to others, I'm not going to be tethering my camera to the TV and showing them their. For quick preview with your family, this might be useful, but in the market that a usual DSLR is in, this doesn't seem necesary.
