Last time I looked at ML you had to install it with every card change, or have it on every card, which made it a no go for meIs that still the case?
From reading the install PDF, that still appears to be the case All rather too scary.I wish Canon would wake up and offer a significant upgrade to the 5dii's firmware like this. I'd happily pay quite a lot for it. Few manufacturers seem to have woken up to the potentially lucrative paid firmware upgrade idea.
