Wolverine shot was lucky. But photo, from pure photography perspective, is quite poor. I had SLR around my neck (otherwise I'd not have time to get it), but had only my wide landscape lens & could not zoom enough. This was already at 105mm, max focal length & it needed at least 300. Then it was already too dark for focused handheld shot, 1/30 sec exposure. It is quite blury at 100%
Still I can't complain, how often do you get to see not one but group of wolverines in the wild. Magic moment
