Someone asked upthread about gear. This has evolved quite a bit over the last 3 months:
Sony a7r w/ FE 35mm F2.8 ZA (21.3 oz.; inclds battery and tripod mount)
REI Trail 2 Waistpack (4.8 oz.; fits above configuration snugly)
Sirui T-025x Tripod w/ ball head, top extender pole removed (27.7 oz.)
Suntactics sCharger-5 (8.6 oz.)
USB2 charger cable (0.8 oz.; I may bring extra as this is a likely failure point)
extra 64Gb SD card (negligible)
2 extra batteries (3.2 oz.)
Rokinon 24mm f/1.4, packed away for night shooting (23.1 oz.)
Zeiss Batis 85mm f/1.8 (16.9)
(& some cleaning gear)
So about 6 lbs including power. That's a mix of owned and rented gear. Actually, much of my "evolution" came about because I payed $75 to lensrentals.com for a year of free shipping, allowing me to try out different options (I highly recommend this to anyone). I first tried Sony RX1r thinking I would go very simple and light (18 oz but fixed 35mm). I think my creativity is better when I have only one focal length to think about. However, it just won't do the job I outlined above, so gear list had to expand. I took some picts with the above setup (35mm lens only) on a recent trip up to the Ontario side of Lake Superior, posted at my brand new photo site
here. Hopefully I'll have a nice Sierra section there in September! (And a trip report with photos here of course.)
One equipment note: Contrary to reviews, the a7r (and I assume all other a7 cameras) charges the battery in only 2 hours if you use a 2 amp USB wall charger and decent cable. It charges in 3 hours with perfect sun from my Suntactics sCharger-5. (The camera comes packed with a 0.5amp USB wall charger and a very wimpy cable that make this 5-6 hours, the spec given in reviews.)
I'm currently playing with different ways to arrange gear on myself. The waistpack with its tiny load is quite comfortable strapped under backpack, with compartment laying over backpack straps in front. It's easy to get to and doesn't obstruct my view of the ground. I hiked many miles (in dark and/or rain) in Ontario with the Sirui tripod simply tucked over my waistpack strap. With backpack I'm experimenting with a loop on shoulder-strap. (The trick with this tripod is to leave the top extender part at home. It all balances much better that way in its folded configuration without flopping around. And more stable as a tripod without it.) The Rokinon stays packed away for night shooting only. I still have to figure out how to carry the Zeiss Batis lens. I'd like to have it out and available, maybe on the other shoulder strap in some protected compartment (?). This is a rental and I understand that sand is the one thing not covered by the "lenscap+" insurance.
