The kilo thread made me weight my 62mm cpl filter + box : https://www.mu-43.com/showthread.php?t=55340 my list for my next 2 weeks hike ( i should be able to charge batteries every 3 days ) : em1 : 497 12-40: 380 batteries : 3(-1)*50: 150 charger : 120 uk adaptator : 25 polarizer + box : 75 dust blower : 57 lenspen + microfiber : 20 cuben fiber : bag 60 I thought i could cut some weight using screw cap, and i bought the JJC one. http://www.amazon.co.uk/JJC-Aluminium-62mm-Filter-Stack/dp/B0051EXH6E/ref=pd_sim_ce_5 unfortunatly, for hiking it is a bit heavy at 52g. I have tried some myog dyneema + microfiber pouch but i want happy with the result. any lighter ( non metal ) screw cap ? or any light box ? i could also buy 2 cheap filter and could use one on each side but i would prefer finding some light resin or plastic screw cap.
