I was going to stay out of this discussion because the above advice was all good, but I was bouncing through
B&H's website and saw some things.
First, I expect that you know this, but if you are travelling through other countries, it is best to have bought all your equipment in real stores and have bills of sales to confirm it all. I have rarely heard of problems, but what problems I have heard revolve around confiscation of equipment. The bills of sales will not necessarily stop this, but at least you might be ready to argue for compensation from your insurer. Oh, right, be sure your equipment is covered by your insurance.
Next, if everything were "normal price" I would probably recommend Micro 4:3 (either Olympus of Panasonic), or Fuji. Fuji has small lenses. Many of the other APS-C cameras do not have many "small" lenses. Canon and Sony both tend to rely on you using "Full size" lenses to fill out their product lists. Sony actually is not a bad situation. They do have a good array of true APS-C lenses, and there is even some good third party stuff. But yes, really they do expect you to buy some of their bigger stuff. Also, there are good Canon lens adapters that will allow full auto-focus on Sony (and Micro 4:3 bodies as well). But that really is a mark in favor of Fuji because the actually do have more small size lenses to cover you. And actually, I think there is a Metabones full automatic Canon lens adapter for Fuji as well, but I am not sure.
BUT, all things are NOT normal prices right now. As I said, I just went through BA&H and they have some significant sales on:
"Panasonic Lumix DMC-GX85 Mirrorless Micro Four Thirds Digital Camera with 12-32mm Lens (Black)
B&H # PADMCGX85BB MFR # DMC-GX85KK"
"
Panasonic DMC-GX85 Lumix Mirrorless Micro Four Thirds Digital Camera"
- $597.99 US including 2 zooms (the 12-32mm kit zoom and the 45-140mm zoom. They are advertising this as a $200 saving, but really it is over $400 saving. The camera has an eye-level view finder without the lumpy top style.
"Sony Alpha a5100 Mirrorless Digital Camera Kit with Black 16-50mm and 55-210mm Lenses (Black)
B&H # SOA5100BK210 (
B&H Kit)"
"
Sony Alpha a5100 Mirrorless Digital Camera Kit with Black B&H"
$648.00 US including 2 zooms (the 16-50mm kit zoom and the 55-210mm zoom). This is not such a wonderful deal because I do not consider the a5100 to be worth as much as a Lumix GX85, and for better or worse, you into the Sony lens system which I mentioned above.
"Olympus OM-D E-M10 Mark II Mirrorless Micro Four Thirds Digital Camera with 14-42mm EZ Lens (Black)
B&H # OLEM10M2KB MFR # V207052BU000"
"
Olympus OM-D E-M10 Mark II Mirrorless Micro Four V207052BU000"
$549.99 US including the 14-42mm EZ Lens. They also have a 2 zoom lens kit for ~$650 US.
There may be other similar deals at other stores right now, and maybe one with a Fuji in particular. But if you like these deals, it does sound like you will be able to walk away with some cash still in your pocket for a nice lunch. . . .
