Re: tripod and lens IS?

Okay, so I took a couple of test shots to try this out.

There are two sets of two photos. In both sets, I shot these in One Shot to eliminate any vibration that AI Servo might cause. I Enabled mirror lockup, and set a 10 second shutter delay so that I would not be touching the camera. The lens is a Canon 18-135 IS USM.

These were taken on a cloudy day at 5600K White balance. I shot these in Aperture Priority (Av) mode of f/7.1 and Auto ISO, so the shutter speed and ISO will vary between both sets. I should also tell you that these were taken in Live View.

I was looking for vertical and horizontal lines.

In each set, the first picture is with the lens IS set to on and the second picture is with lens IS turned off. I did not resize these pictures so that you could view them in original size.

Set# 1 Shot at 85mm from about 50 feet from the subject. The shutter speed came in at 1/125 and the ISO was 1250

Lens IS On

Lens IS off

Set# 2 Shot at 121mm from about 30 feet away. Te shutter speed came in at 1/250 and the ISO was 3200.

Lens IS On

Lens IS Off

What do you think?

Any appreciable difference?
