Gotta love "Canon Prime Lenses" though, solid!
1 x Hoya 72mm Pro1 Digital UV Filter that I had to prize ever so gently, (NOT), of the end my Canon EF 50mm f/1.2L USM Lens. This little bugger was cross threaded so tight I had to smash the glass element and wrench and twist like buggery to get the damn thing off! If you’re not damaging your kit every now-and-again, then you’re not taken nearly enough photos, even with all the care in the world, accidents will happen. It's just a pain when they do!
