wyoming: maybe it's the best superzoom camera on the market (exept for the price), but in my opinion on this kind of camera it's mandatory to use AA batteries.i'd never considered to buy a superzoom, i have never needed a 24X lens on a camera wich is bigger than a mirrorless but has a compact sensor.but if i try to see the piont to buy a superzoom i imagine someone that goes in a remote place and must stay as light as possible (or he could bring a panasonic gh+ a tele lens).in this situation it's ridiculous to force to have a spare battery in the pocket.
As AA batteries usually have much shorter life than the dedicated rechargeables, you would need to carry spare AA's with you. Also, the AA's are heavier and bulkier (which also makes the camera heavier and bulkier) so I always prefer a camera with a proper rechargeable battery. What I really want though is the option of charging via a USB connection so I can use mains, car, solar or external battery pack for charging.
For travel, my ideal would be a modern version of The Canon Powershot Pro 1 with APS-C sensor (about 16 MP) and 24-200 zoom, preferably around the f2.4 max of the original. With latest technology it would be a bit larger but should be worth it for the usability and quality.
I use a Retrospective 10 for my Eos 7D with a couple of extra lenses but really want something of similar quality (without 'shouty' look at me labels) for my Sony NEX-5N kit. Best so far is a Domke F-5XB but the needle holes from its ridiculous front label (immediately removed) are a bit unsightly and its velcro front is far too noisy. A shallower version of the Retrospective or City Walker 10 (to take a 7" tablet) would be ideal.
