Re: Two options for IS on 300mm prime

Mode 2 is great for "panning" shots.  When you shoot a moving subject at a slower shutter speed and follow them...  a fast shutter would just "freeze" the shot (and make it look like nothing is moving).  A slower shutter will result in the background blurring and implies the sense of speed or motion.




This blurs the background and the wheel spokes... but everything else looks reasonably sharp.  For this example, the camera needs to be following the car as it drives by ... but you don't need to be on a tripod because mode 2 will correct for up/down shake ... but it wont fight you as you swing the camera left-to-right (mode 1 would fight you).


It's a somewhat common technique used when capturing racing.  I use it when I shoot bike races. 


Some newer lenses have a mode 3.  Mode 3 is basically mode 1 with the exception that it is _only_ active when the shutter opens (so it wont fight you as you try to frame & focus a subject).  This is because mode 1 activates the image stabilization anytime you wake-up the focusing system (whether the camera is taking a shot or not.)

This is a great example for option 2.  Thank you for sharing.  I am a visual learner, so this helped a lot.

Re: Two options for IS on 300mm prime

I have the prior version 300 F2.8 and I very rarely activate IS but I have used Mode 2 for panning shots of runners and as Tim illustrates it is very useful for that type of capture.


Mostly I am shooting field sports with a very fast shutter speed so IS doesn't offer any significant benefits for me and does increase battery drain.  For use on a tripod I would disable it unless you are shotting in an earthquake zone Smiley Sad
