I had the bright idea to make the viewfinder masks for my Mamiyaflex so I could try using the 'sport finder'. Next bright idea was to try to shoot a middle school football game to test with HP5 @ 1600. I haven't developed the film yet so it may just be a mess. My technique was to prefocus just my side of the home team hash marks and stop down as far as practical - which was only f8 @ 1/30 on a 180mm. I also had a flash attached for the 2nd roll so maybe it helped.
Is there anyone who has shot sports successfully? I'd love to see some examples as they are hard to find on flickr and such.
