So i've been snapping away wildly all weekend with the 5Dmk3 and there are a couple of things that bug me
overall the build and handling are significant steps up but there is some silly stuff going on.
1 - The rate button, probably the single most useless button I have even seen on a camera EVER, which would be fine if you could assign it a usefull function instead such as a bracketing button like ever 1D has had since the 1Dmk1 remember that good ol 4MP kodak sensor? its nice to just hold a button down and scrollt he wheel bringing up the bracketed stops. having to go into the menu to enable bracketing on a PRO body is just plain lame. This could easily be fixed with a firmware update to enable assigning of more functions to that button
as for rate and protect the whole 2 features you can choose this button to perform, very underwhelming. As it is this button is a total bull tit.
2 - out of camera Jpeg files are horrible, accross the board there is far too much smearing going on they are well and truely overcooked, mushy and about as sharp as a bowling ball. I like to have medium jpg files writing to the SD card so i can just pop it out to give someone quick access to the pics without jumping through all the raw processing hoops. As it stands I'm really not going to give anyone these jpegs so i've turned it off all together until an update comes out.
This is particularly concerning because all the talk from the marketing machine talked up how all the improvements of blah blah stops is based on jpegs. If this follows through to the 1Dx there are going to be alot of unhappy people with $6500 less in their pocket.
3. RAW processing, I'm a bit amazed that none of this was sorted out prior to release, neither DPP or adobe are producing satisfactory results. The only way i can even see the detail i'm chasing is in DPP preview.
4. AF isnt as good as i was expecting in AI servo but I'm still playing with it (there are lots of settings to play with and test) so i'll have to reserve judgement on this but as for just turning it on and shooting with AI servo in standard mode the 1Dmk3 still eats it alive both in speed and accuracy
Perhaps I am doing something wrong maybe 7D users have some tips on getting the most from these new AF systems in AI servo.
