I'm sorry... I'm a one body type of guy lol.
Canon or nikon or sony or fuji. Not both.
I've slowly transitioned to where I really like DPAF and find myself using DPAF alot for shooting more so when I video I'll flip over to live view for photos and then move back to video for a few more clips.
This was my biggest attraction toward sony. For me it was a progression. I need an all in one video/stills camera. Sony offers the best solution at this moment with the IBIS since I shoot handheld alot. I'm not a pro video guy w/ a gimbal rig... just need one camera.
I'd say the A9, A7RIII or A7III now offer better all in one capabilities over the 5D4. Ever since the battery became larger, grip became a bit thicker and the joystick I could no longer argue ergonomics. When the 5D4 was released... sony didn't have it. Now Sony does. Time to jump ship.
I'll probably be listing the 5D4 up for sale before end of March. I sure will miss that tactile mirror slapper though.
Oh... my other issue was lens selection but I think sony has done a good stride to get us the core. They are missing a few things. I"ll adapt my fisheye since I don't want to get rid of it and I'll adapt my 200/2 for now. Now that the Sigma Art's are going to be E mount and sony releasing a 400 2.8 they are doing well.
