Here is a list of my most frequently used equipment, and what I use it for. Click on a link to see it on Amazon. Using these links to buy equipment helps support me.
Primary camera
Secondary camera, B camera for video
Backup in case shit really hits the fan
Large stages, big clubs, festival candids, fashion, general purpose in large open environments
This is my go-to lens for events; it's fast, versatile, and sharp.
Crowded clubs, group portraits
Creative fisheye shots, ultra wide angle shots with post-production correction
Nothing beats this lens for portraits
Products, beauty/glamour, fashion, candids, single-person portraits, general purpose "walkaround" lens.
General wide-mid range daylight shots
Camera stabilizer
One-person interviews/narratives, candid videos
General purpose audio and replacement for in-camera mic
Remote flash triggering for portraits, fashion, publicity, etc.
General-purpose light diffuser. Great for club portraits, and softening off-camera flash in fashion/glamour.
All-purpose flash
Usually in my bag for fashion shoots. Mainly useful for bouncing sunlight.
A superb all-use tripod. Don't skimp on a good tripod -- my first was a cheap amazon basics and started falling apart in less than a year.
