Question about Canon EOS-20D Digital Camera with 17-85mm Lens
Posted by Anonymous on
* Get AF off the shutter release and onto the * button using the custom function. * Use the center focus point only. Force yourself to pick what you want in focus, AF, then recompose and shoot, a habit far more effective than computer driven multiple AF points for just about everything. * AF performance degrades in low light no matter what camera you own. This is life. At least if you control the when/where of AF, you can try and choose high contrast points in the scene to focus on, points that will help mitigate the low light. * Not sure if this applies to you, but it does apply to many a pixel peeper...if something prints sharp at 8x10 or 11x14 then AF has succeeded even if it's a little off at 100% in Photoshop. AF is not perfect and the tolerances are not necessarily up to producing 40" enlargements, which is what 100% in Photoshop is. Having said that, in good lighting with good target contrast the AF on your 20D often will nail focus so perfectly that it will hold up even at 40".
