What's in my bag you ask? Well, being the camera and gear junkie I am I might as well share with you...
I'm a Nikon guy, nothing wrong with the other manufacturer's out there but I just prefer the feel and controls of a Nikon as well as the high quality images it helps me produce.
Nikon D750 (my work horse, nothing beats a big full frame sensor and a proven performer)
I am a lens addict, give me some fast glass and I'm a happy man. I mostly prefer shooting with fast prime lenses but I do have one fast zoom I love to use when the situation arises.
Sigma 24mm f/1.4
Sigma 50mm f/1.4 HSM
Nikkor 85mm f/1.4D
Tamron 90mm f/2.8 1:1 Macro
Nikkor 16-35mm f/4VR
Tamron 24-70mm f/2.8VC
Nikkor 70-200mm f/2.8 VR
Over the years I have learned to make the most of available light so I will use any light I have available to me :-) natural light is great at times but being able to add and or tweak that natural light with some off camera light of my own adds another dimension.
Nikon SB-600 x2
White Lightning X1600
Alien Bee B800
That's the bulk of it, there's also numerous light modifiers (softboxes, umbrellas, beauty dish, etc), and a handful of ND and CP filters along with some other little goodies I forgot to mention.
