So my friend Matt has allowed me to baby-sit his 200mm f/1.8 Canon L lens for a little bit. The thing is a monster and quite heavy. I'm only mostly re-assured that the neck strap attaches to the LENS not my CAMERA. But seriously, Canon doesn't make this lens anymore and I'd hate to have to replace it.

'Dad, your new lens is broken, I can't see anything...'

'Yes, Son.'
