Summer is on its way and the X1D handles the high contrast sunlight like a champion. Medium format sensors have enough headroom to hold the whites of the surf and give you shadow details as well.
It may be a little slow to start but once it gets up and running it works as quick as most of the current smaller sensor mirrorless cameras. The latest firmware update is starting to show the potential of the system and the lenses are still amazing.
I can't help it- they are great lenses!
