Here and also in Finnish newsgroup sfnet.harrastus.valokuvaus (photgraphy group) has been talk about EOS3 not having cross type AF sensors active when the aperature is slower than f/4. Here's brief summary of a message posted to that newsgroup. Testing done with EOS3 and EOS300 usinf EF 100-400L at the 400mm end (f/5.6). Light level was about half a sec using ISO 100. EOS3 couldn't focus to the edge of board on the wall (vertical line). EOS300 could focus, albeit slowly. To horizontal line, both focused with similar speed. When taken to moderate light, EOS3 was superior. It could track flyinging seagull in day light (1/400s, f/5.6 @ISO 100) quite well. With EOS300, there was no hope of achieving the same. Testing with fast lens (EF85/1.8), both were very fast. When there was any difference, it was for EOS3's benefit. The tester couldn't find a target where EOS3 couldn't AF on. Testers conclusion was that when light level was high enough to photograph without a flash, there was no problems with EOS3's AF. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
