funny you say that, I may be able to grab a 300mm f4L tomorrow. I'm a regular customer at a camera shop here they do ALL of my printing I've spent a small fortune on film developing here they said to come by tomorrow before I leave they may let me hold it. I have no filter for it though it's like 82mm or something gigantic.
I planned on mostly wide angle shots but wanted one or two closeups. I have a d****al but the lens on it is not compatible with my Elan (because it's formatted for d****al, which means I get to upgrade)
I'm not worried about exposure it's sunny Florida that particular camera with Elite Chrome 100 was letting me shoot 500 f/8 with an orange filter no exposure compensation. The launch is at 3pm so as long as it doesn't get delayed 2 hours I should be fine, but a 2 hour delay would make for some awesome lighting.
