70-200...for those that have IS

Shot this the other night at graduation indoors....was playing around with my stops and what not and come up with this....I know it is OOF but the the bokeh is different for sure. Question, would I of got a better IQ if I had IS on the 70-200 2.8. For those of you who think this is a dumb question, well, my thinking is I won't learn unless I ask.

thanks

only thing IS will do is help prevent camera shake i dont belive it has anything to do with IQ

The background is blurry because of all the motion, has nothing to do with the natural bokeh of the lens at the focal length, appeture, and subject distance used.

Motion. Tons of motion. To increase the sharpness of your subject, IS helps, but also a bit more than 1/10 shutter and ISO 800.

I would have tried at least ISO 1200 (or 1240, whatever the inter-step is), and f4.0 or even wider.

This would have given you -along with panning, IS mode 2- a sharper subject, and a blurrier background, at a more tolerable speed.

Then if there is noise in the picture, you can PP it or work around it.

thanks...that gives me something to work with in the future.

You needed three things to work for you to get the lady sharp and the people blurred out:

1) The focus
2) Shutter speed
3) The panning technique.

So you had this:
F6.3, 1/10 sec at 160mm, ISO800

1) Is she moving towards you or away (I reckon towards you), follow the route and manually focus to where you are going to take the shot. She wasn't the first pupil right? So you can practice on the movement of others to get the focus right. Or make sure AI Servo is on the camera.

2) Using your current lens, opening up the f-stop to F2.8 of F4, increase your ISO to 1600 (don't worry about noise), this would have got you close to 1/100 shooting speed for a panning shot.

3) Follow the person around and be s-m-o-o-t-h with your movement and pressing the shutter.

IS would NEVER have gotten her sharp and the background blurred.

This shot is all about technique, not wether you had the right lens/camera or not.
