Is the Speedlite 600 overkill?
Get the 600rt if you want...
- 200mm zoom setting
- great menu/wheel usability
- the power output of a "large" flash
- 1dx/5d3-compat af assist beam
- radio control (i.e. buy at least *two* 600rt)
- group mode (i.e. buy at least *three* 600rt or want to use a m-ettl mix) ... on 7d, you also need the Yongnuo yn-st-e3 controller as it's a pre-2012 camera body.
Don't get it but cheaper flashes if you use...
- your pop-up flash as an optical master
- max power setting a lot (fries the expensive flash sooner or later)
- or manual mode a lot
- softboxes and other modfiers that require multiple flash units
Do wait for Yongnuo's clone that's bound to arrive soon if
- you're ok with a simpler af assist beam
- want to save money
- want to use 2nd curtain remote
