I pack everything in one small leather holster. My criteria is simple, if it doesn’t fit in the bag, it doesn’t come.
Olympus Pen F (2 bodies)
Olympus 45mm f1.8 - for portraits, medium telephoto scenics
Panasonic 20mm f1.7 - for architecture, wider scenics, street photography
Olympus 40-150mm f2.8 - for the Gannet bird colony
Olympus 1.4x tele-extender - for the Gannet bird colony
Grad ND filters 0.6, 0.9, 1.2 - for sunrise and sunset opportunities
Circular polarizing filters - for mid afternoon shooting when the sun is high in the sky
Lexar 64 GB memory cards - reliable and hold thousands of shots
Gitzo tripod and Kirk ball head - for long exposures, especially at dawn and dusk
Electrical adapters for New Zealand
Minus the tripod, this all weighs about 10 pounds, making it easy to travel and shoot with. This of course is in stark contrast to my former DSLR set up which rang in at a hefty 30 pounds. Ironically I find that the current stripped down kit is more capable. Someone once told me, “there’s a fine line between having enough gear, and lugging too much.” By limiting myself to the bare essentials, it forces me to engage creatively, think outside of the box, and work to create unique shots.
