I'm in a similar boat with an upcoming trip to Hawaii, also thinking of one MF and one 35mm, but undecided which. I kind of want one big and slow for the unique photo opportunities and one small and fast for the family snapshots.
There will likely be something d------ hiding in the bag, too. The wife insists. :/
One possible pairing: Great Wall DF-2 (think poor cousin to your Pilot) and a Vivitar UWS. Also thinking of swapping out the Vivitar for either an Olympus XA2 or Rollei 35S. Another possible pairing might be either a baby Graflex or a TLR, and a Ricoh 500G.
Easy. Take one camera. A holga. Take two of them. One for ISO100 and one for ISO 400.
I *almost* bought a Holga just for the trip. Instead, bought a Ferrania Ibis 66 (think aluminum Holga with a collapsible lens). It should be here in about three more weeks. I thought I'd shoot a roll or two and then decide if it makes the short list. The hard part, at those latitudes during the summer, I might need an ND filter, even with ISO100. Mid-day could be 2+ stops overexposed.
I'm *really* on the fence about my Nikonos-V. I so want to shoot film in the surf, but it should really have fresh O-rings, even in the shallows. Tempted to roll the dice, just because it'll likely be another decade before I'm in the surf again.
The takeaway is that:
- I think the 1 MF plus 1 35mm is a good idea, and
- I have too many cameras.
