Hello, this is probably a silly question that nobody can answer but myself. Even though I know that, looking for perspective from others with more experience. I'm relocating to Australia for 5 months starting in a week - will be an academic sabbatical, so I'm doing research but will have a good amount of time for traveling. Lots of photos of my kids, both in the house and out in the bush, plus some travel photography of scenery, cityscapes, wildlife (hopefully).
I'm bringing my 5D classic, and definitely my 28/1.8 and 85/1.8 - my can't-live-without lenses. I will also have a S95 with me. Other things I could bring:
EF 20-35 (f/3.5-4.5 version)
430 EX II flash
If I stick it all in my big bag, it's insanely heavy (at least by my standards). I don't really want to carry such a thing on the plane - and I assume it is not advisable to check photographic equipment unless you have a hard-sided case of some sort.
There's something nice about the 5D/28/85 combo and I can handle a lot of different situations with that setup. Downsides are i can't photograph dramatic vistas at 20mm, can't photo anything far away (like kangaroos and whatnot), and lack the versatility of the 28-135 (although the S95 really takes care of that for the most part).
Anyway, I'm aware that this is an unanswerable question - just looking for any advice people are willing to offer.
