Can you point me to any alternate "hoods" that would screw into an 82mm filter thread? I have a Mamiya rubber lens hood that screws into a 77mm filter thread but that one is for longer lenses. I use it for shooting hockey with my 70-200mm and 7D... I especially like it if I'm ever shooting through the glass... I can put it right up the glass and if the players hit the boards or someone bumps me it has some give so I won't get a black eye!dilbert said:Baffles can help here, as can an extra hand by itself or holding a card/hat/etc to keep out stray light.neuroanatomist said:I have a couple of step-up rings (67mm and 72mm up to 77mm). No issues with vignetting. One problem is that, with rare exceptions, a step-up ring and larger filter precludes use of the lens hood, meaning less contrast, more flare, and less protection. They also tend to get stuck, so have a set of filter wrenches.
The hood isn't the only way to block out incident light. Just look at the baffles used in hollywood.
