Need An Expert's Help

Mon Oct 31, 2005 5:41 am

I've been having trouble with a particular shot. Here are the particulars:

Camera: 300D

Mode: Using AV, ISO 100, aperture at both 8 and 11

Lenses: 100-400 IS L, 70-200 f/4

Conditions: Sunny, 9-11 AM

Physical Setting: at close proximity to aircraft on final approach

My problem is that my shots are showing a bit of blur, even though I believe that I'm panning perfectly.

Should I switch to TV and set the speed?
II Cor. 4:17-18

Sunny, 100 ISO and f8 should result in a shutter speed of about 1/500s. Fast enough take away any blur. I hardly ever go over 1/500s, even with 400mm (although stabilised).
If you still have blurry pictures, either your (auto)focus is messed up, or your (panning-) technique needs some work...

The problem might be very simply Sleekjet as you are using a 300D which does not feature a constant servo AF setting.
If I remember correctly it is supposed to switch from "one shot" to servo when it detects movement of your subject automatically.
So try to fool your camera before you start shooting by focusing on different objects.
Or update the firmware by one of the enhanced(read 10D) versions offered on the internet.
I guess other 300D users will know how it works.
Maybe you can post an example ?

The truth lives in one’s mind, it doesn’t really exist
