Hi there Erik,
Apologies for the late reply.
Thank you for the recommendation. Yea weight will be an issue carrying two systems.
I might be making a classic mistake by bringing too many lenses. On one hand, I'm worried I don't have something either wide enough or long enough for a shot. We'll see how it goes, I have another week to decide.
The Gura Gear bag you mentioned looks real solid. I'm not sure I've seen this brand around in K.L, Malaysia. A lot of the ones I see are ThinkTank, Lowepro and KATA. There is this one brand called Caseman which I think is Australian and reasonably priced. I checked out one of their bags recently and it seemed pretty sturdy.
Any how, thanks again for the feedback. Much appreciated.
I have a Gura Gear Kiboko, the original model.
A Hasselblad 555 ELD with P45+ back, PM5 viewfinder and 40, 50, 80, 120 and 180 mm Hasselblad lenses
it also contains
A Sony Alpha 99 with a Zeiss 24-70/2.8 mounted, a Sony 70-400/4-5.6 and a Sigma fisheye and/or Sigma ultra wide zoom.
If the Zeiss is not mounted I can probably carry a bit more, but there is also something called weight.
The bag fits in the overhead bin of a Canadair Regional Jet, the main reason I bought it.
