Sigma 60-600mm Lenstip Review

That's what Thermal cameras are for... Oh, except maybe a hot rock and a wolf look similar?

I can 'hunt' hedgehogs in the dark with my thermal camera...:)

That's about the only wild critters around my part of Hampshire.... apart from Badgers , Foxes and Deer... but not in my garden!

Thermal cameras... wolves have thick fur. I'm not sure how well IR would cope - although I did discover that some green parrots are black to an infrared converted camera, and kind of think some snakes with infrared pits must find them tasty. I'd tentatively tried to suggest that a computer vision team might like to memorise what the local foliage looked like each time the Yellowstone tour bus went past (allowing for a bit of parallax) and provide a highlight for the driver if something was different, and might be a wolf/bear/elk. It might make an interesting student project.

I have an enclosed rear garden with houses that have pet dogs on each side. My garden used to contain cats occasionally; these days it's birds only (except for the occasional neighbouring cat). We get foxes out and about but not in the garden (in a previous house we had a vixen nursing her cubs in the garden), and I drive past an area containing deer each day; I think I've only seen badgers a couple of times. Hedgehogs are a bit more common, just not in my garden. Which reminds me of a time I was walking home through Cambridge one day and saw a roadkilled hedgehog on the side of the road... with a new no-parking yellow line painted over it. Pathos. Otherwise there's the odd squirrel nearby, rats and mice, but that's most of my local wildlife. Anyway, in Yellowstone I was apologetic for making noise but confused when everyone got excited at a red fox (or a swan), but Americans couldn't understand why I was excitedly photographic coyotes and racoons...

I can see why the US has 'issues' with exporting thermal tech.

On a very clear night I could pick up a 474 at 35000 ft with a Android attached cam costing ~ £200

the odd squirrel nearby

What's odd about it...;)
