Anyone here currently shooting with two or more camera brands? I mean actually using two or more brands on a routine basis.
I currently shoot with both Nikon and Canon. I pack my 7dmk2 and my D750 in the same bag when I go out shooting anything of real interest. Somedays I'll take the 7dmk2, the next day I shoot with my Nikon D750.
I enjoy using both systems plus I have different lenses for each brand. For my 7dmk2, I shoot primarily with my 16-35mm f4.0L and my 70-200mm f2.8L. I recently purchased a 28mm f1.8 USM for it as well.
With my D750, I shoot mostly with my older AF-D primes (24mm f2.8, 35mm f2.0, 85mm f1.8, 180mm f2.8 ED) and my older manual focus primes as well including my 105mm f2.5.
My reasons for using both systems is that I enjoy the clean, fast images I get with my 7dmk2 (plus it's built like a tank, feels solid and heavy, fantastic build quality). With my lighter D750, I enjoy going light with small primes. Images are sharp, settup is great for when you are shooting all day and need a lighter camera. Funny thing is that, imo, there is virtually no difference in IQ between both cameras despite the differences in sensor sizes.
I still have my Lumix m4/3 system, but I gave it to my younger kid as I never cared for the IQ compared to even my older cropped sensor dslr's. I will occasionally use it to capture astronomy images attached to my telescope mainly because it is the lightest interchangeable camera I have (attached to a T mount adapter).
Anyone else here currently use two or more camera brands or systems? If so, what are your reasons for doing so?

. This comes in handy when travelling for work. I generally use MFT for snapshots as well.
