Nah beef is heavy, just make sure you're not the slowest runner in the pack!
A friend of mine used to be a salmon fishing boat guide in Alaska, where there were a LOT of hungry,feeding bears. He was
required by the lodge he worked for to have, at ALL times while afield, a 12-gauge pump shotgun with an extended under-barrel magazine, loaded with specialty ammunition. typically they loaded the barrel with a premium magnum load of 00 hard-copper-coated buckshot, followed by a heavy, deadly Brenneke style slug as the first round in the magazine, then a buckshot round, then slug,slug,slug,slug, slug. Eight total rounds. Plus noisemakers for each angler, whistles, air horn, and bear spray. Perhaps the tour people or lodge/guides on your trip will be similarly equipped.
Yeah...anyway, that was Alaska, where big bears, and small streams, and salmon and fishermen all mixed and mingled. At CLOSE distances. The danger is mostly from surprising a bear as you walk through tall grasses and willows and such...THAT is apparently when bears get pretty nasty--when surprised by quiet-walking people...so...each angler was given a whistle and some noise-maker dealies (jar lid bands worn on a necklace) for when he moved from spot-to-spot along the streamside. In open areas, it was not such a big deal apparently.
Anyway....yeah...that 50-500 Sigma is slooooow. I would much rather have a "fast" lens, like say a 200mm f/2.8 Canon prime. Or even a slower, but very sharp small prime, like the 135mm f/2.8 Canon Soft Focus. or the 300mm f/4 IS prime. if you've never hunted or stalked big game, you 'might' very well be afflicted with what is called buck fever...you can get a huge,huge shot of adrenaline, and elevated heart rate, jittery muscles, and short, shallow breathing, and that can make it difficult to be steady. I hope you have a good trip.
