[Rover]

I was about to point out that error in taxonomy, but you beat me to it.

Technically, spiders are not insects    :lol:

Rover, what brand/quality were those extension tubes?

 

As to what brand the tubes were... probably Aputure. Serves me right for choosing outright junk (and for not supporting the lens by the tripod ring at all f'n times). I got out with less damage than I could have... for what it's worth the lens might've fallen off the cliff, or onto some hard stone. It did get some sand inside so for a minute or so the zoom action was grinding. The mentor at the photo tour I was taking said "Hmph... just keen on spinning it, something's gotta get ground down - either the sand or the lenses inside".
