I am not going to review any gear I own, as there are plenty of reviews out there for every gadget under the sun, but, I am just going to list the gear I use in case you ever wondered what goes in my bag.
Nikon D800: My main full frame DSLR. Versatile and Capable of anything I throw at it.
Nikon D80: My first DSLR. Old but still produces sharp images if coupled with a sharp lens.
Sony RX100 IV: Professional photographer camera in a small pocketable body. Best camera for when you don’t want to carry heavy equipments around.
You spent a lot of money buying your gear so you might as well spend more to protect it. Camera bags are essential equipments to carry and protect your expensive gadgets.
I haven’t got involved deeply in Flash photography, however, SpeedLight is almost a must in every photographer bag (Because you never know when you will need one, right?)
