2 Days ago i sold my Nikkor 24-70 f/2.8. This morning I hit up Amazon this morning and pulled the trigger on a.... Panasonic 12-25 f/2.8 Tiffen 58mm ND filter kit Battery grip 2 more batteries Pin hole lens body cap New garbage disposial <-- not :43: but i needed it. All to be delivered on Monday! I am still selling off my Nikon gear, Phase 3 will be the 35-100 f/2.8 and a backup OMD. I am sort of going a different direction than most time-lapse photographers, rather than going to a larger sensor I am going to a smaller one, but I am convinced this is going to be the way to go. my last timelapse hiking kit consisted of Nikon D7000 w/grip Canon 60D Tokina 12-24 f/4 Nikon 24-70 f/2.8 Nikon 70-200 f/2.8 3-4 spare batteries rain sleeve for the canon Chronos 2.0 which is a 39 inch timelapse rail I developed. Everything together came out to 30lbs. Add in a tripod, water, snacks, sunscreen, regular hiking supplies and it swelled up to about 40lbs. I like to carry a spare camera and a couple lenses so I can play around with photography while my timelapse system is clicking away. The move to :43: is an attempt to lighten the load. I am pretty sure 2 OMD's with spare batteries and the 12-50, 12-35, and 35-100 will weigh in under 5lbs. The new timelapse rail i am designing should be under 7lbs when fully constructed. I am really looking forward to hiking some Fourteeners next summer! I have a couple lowepro bags, but i am hoping to find something that has a smaller compartment for the :43: system and plenty of room for hiking supplies.
