They've done that before. The 10D's grip (BG-ED3) is different to the 40D's (BG-E2(N), same for 20 & 30D too) and so when I upgraded from my 10D I had to get a new grip too, despite the 10Ds grip having better ergonomics. In doing that though they did introduce a couple of features missing from the BG-ED3 such as the AA battery tray, support for a couple of extra Li+ battery types, improved weather sealing etc. I would 'hope' that with the change for these cameras comes a few additional features that makes it worthwhile for upgraders to buy another grip, but I don't get why they have to make the outgoing models incompatible in the process (other than greed).

There is a good reason for changing the grip in this case. Many times the dimensions of the camera changes, so the old grip physically won't fit, but in the case of the 7D Canon upgraded the weather sealing, especially following the weakness of the battery grip on the 5D MkII. So perhaps that's reason enough? Or maybe you would prefer that progress wasn't made so old equipment can be reused?

That's not necessarily a valid reason. They could have still built it in such a way that the other grip would fit.

Again, that shouldn't preclude owners of the other grip from using it. It's a feature that has no bearing on the layout of the grip. It's an incentive to upgrade for some, but for those without the budget they could still have been accommodated if they'd chosen to.

Progress shouldn't preclude the matching up of a couple of bits of metal or plastic. The dimensions of the camera base could have been laid out to match the old style grip easily enough. In fact, if the fittings of the 10D's grip were to suitably align with a 40D then it would fit better that the 40D's grip which has an indentation on one side when attached. And, in terms of what matters here, when matching physical characteristics rather than advancements in function, the BG-ED3 was a better design than the BG-E2N.

Personally, I think with the BG-E2N there were valid reasons for me to make the choice to upgrade, if I was given the choice to (despite its inferior ergonomics). But unless there is drastic restructuring of the internals of the camera bodies from one model to the next, or in the electronics that required the grips to be different and the layout was changed to prevent use of the old grip, there surely could have been ways to make either work, and to leave the upgrade choice to the consumer.

There's one person at least whose not at all happy with the release of the 550D. Brilliant. http://www.youtube.com/watch?v=xdF-jHkO4AE

Interestingly Canon are going to have to change the battery for the 550D.

The new LPE8 that goes with the 550 has a new charger which doesn't meet the Japanese "Electrical Appliance and Material Safety" law.

Full story on the AP website here

Chris, as I read it, they had to design a new battery to meet the Japanese "Electrical Appliance and Material Safety" law. Which resulted in a new charger. There seems to be no suggestion that this new charger doesn't comply!

I think you're right. I think I mis-read the

"Safety fears prompted Canon EOS 550D battery change"

headline as

"Safety fears prompt Canon EOS 550D battery change"

Oops! I'm off now to write out "I must pay more attention" 100 times.
