IS Test: EF 24-105 f/4L IS on Tripod (TURN OFF IS!!)

While I was taking vacation in Hawaii, since we brought the tripod with us at the cost of $25 for overweight checkin (yeah.. don’t make one big bag for your trip if you are travel with other people. Make one medium size bag for each person!), I tried some long exposure from the hotel room to show my wife what it looks like. I wanted to take at least 25 second bulb shot. So here is the first shot.

Guess what is happening here. IS is on. What a surprise!!! I have not seen this problem with my 70-200 f/2.8L IS, which is supposed to be earlier version of IS. This is a bit of disappointment for this lens’ IS. Good thing that I was shooting digital and noticed this right away; if I were shooting film, this would have been disastrous.

With IS off, this is what I got. Nicer although I still don’t like the light pattern from the building in the center.
