Hi,
getting ready for another adventure next year (Chile, Argentina and Antarctica) and trying to sort out what to take re gear

Have 5D Mk111 and a good range of L series , have just purchased a dry pack (back pack with built in dry bag) but am thinking what filters besides CPL to take and try and keep the lenses to a minimum
thinking 24-105, 24- 70, 70 -200, 16-24 plus 2 x extender
I want to keep it to a minimum but still have the ability to try for some good shots will definetly take my CF tripod as well

have 50mm 1.2, 85 mm, 135mm plus 100-400 all L series
thanks
Bob
