Anything new since May? HDR video?
What is missing for 500D that 550 has?
I'd be happy to read the manual and try the new features. It would save me a lot of trouble if I knew which of the features are not supported by 500d. Are there any like this you can list? Can we document this somewhere? Please point me in the right direction if it's already written down.
I know for sure HDR video is not supported because it can't support any video higher than 30fps. This can be seen in the Magic Lantern User Guide under HDR Video.
Actually the more I think about it, I don't think it would be a bad idea to create chart that list all the features each supported camera is capable and not capable of using.
If i remember correctly HDR was not suppored because it's not working, not because of the low max FPS of the camera (the 1100D has 30FPS max but HDR video is working just fine)
