I am Nikon fan and use mostly Nikon products. My gear is not too fancy. I use one FX and one DX format camera:
Nikon D750
Nikon D90
GoPro Hero 5 Black with Car mount
Nikon lenses are too costly and hence I tend to use lenses from various providers:
Sigma 150-500 mm
Nikon 18-200 mm
Nikon 24-120 mm
Rokinon 14 mm
Tokina 11-16 mm
Tokina macro 100mm
