I have thought many times of jumping ship. I have been waiting over 2 years for the new Canon flagship camera to be launched and when the 1D X was announced I was ecstatic! But this is also where all my doubts started... Delays upon delays just frustrated me and now the way Canon is handling the camera distribution is really annoying me and truth be told... I am not happy with Canon at the moment.
But I also know dumping a top brand you need something better to jump to and in this regard I have absolutely nowhere to go. Doesn't help jumping ship if you will just land in the water - you need something to jump to. The only way I will drop Canon at the moment is if I give up my photographic profession completely... and I have more of a passion for the art than I have a grudge against Canon
