I have owned a 5D3 since December 2012 which I love, for me it is the perfect camera. I used to only use it for Landscapes and aviation, which was clear cut, I was either doing one genre or the other. Now however I am (trying) to shoot a lot more nature, birds and mammals mainly, and whilst the 5D3 is also great at this it is only one camera.
Out in the field I am standing there with a long lens on and all my settings dialled in for wildlife and the light is amazing and I am quite often missing some stunning landscape opportunities. Or once I have given up on wildlife it is taking too long to change lenses and settings etc to get the landscape shots I was after.
The reverse is also true, heading out in landscape mode with a wide lens on, bracketed exposures etc all dialled in I am getting some incredible wildlife opportunities that I am unable to take advantage of. No time to react and change lenses/settings.
So I have been thinking about a second camera, which would also be nice with some of the effort I put into photography trips if one failed. The way I see it I have 2 choices, either make the 5D3 my primary aviation/wildlife camera and add a dedicated landscape camera in the form of a 6D. Or, make the 5D3 my main landscape camera and add a 7D2 for aviation/wildlife.
I would love to hear your ideas about the pros/cons of either choice and any other suggestions.
Lenses I own are 17-40L, 70-200L f4 IS, 300 2.8L ii IS and 1.4x/2x extenders by the way.
Thanks Craig.
