I think the weight saving while not huge is significant Bernard. You have hiked so know that 100g here and a 100g there very quickly adds up to a good or bad day in the mountains. I found when travelling in the Himalayas that having small light kit allowed me an extra lens which was nice. The problem was I ended up with more and more glass that was actually FF and why weight savings started to evaporate.
Hi Martin,
I have saved 1.5kg this year by going from an Osprey pack to a ZPacks one...
The equipment I pack when I walk is split into 2 clear categories:
1. The items that contribute to creating value in terms of deliverable or experience: camera equipment, quality food,...
2. The items that could take something away (safety, ability to execute the plan,...) if not available/not working as expected: packs, tent, pour weather clothes, navigation gear,...
As long as the safety of my group is not significantly put at risk, I go low on weight for items in category 2 and carry as much as I can for category 1 to maximize the value I am attempting to delivery, namely high quality images.
Yes, all that has a cost, but as long as we speak about people with a normal job working in a developed country, most people who can afford a E-M5-III can afford a Z7, the only thing is that they may have to keep their TV or their car one year more. It's all a matter of how important photography is relative to other kinds of spendings.
Cheers,
Bernard
p.s.: when I reach the EBC 10 years ago after having crossed the Chola pass, I was carrying a D3 and a D2x...
Well, I was carrying a D3 and the D2x was carried by the sherpas. I did 4,000 feet vertical last month with a GFX100, 23mm f4, 110mm f2.0, 250mm f4.0, a pano head and a RRS tripod. Had I done that with my Osprey I would had had to leave the 250mm f4.0 at home, and it weights pretty much the same as a whole system based on the E-M5 III.
The point being, that not all grams are equal, and there are ways to leverage improvements to open opportunities to carry better camera equipment.
