It does have IS. It was overcast, so I used ISO 400 after seeing that 200 was a little dark. I generally don't have to go that high when I am outside, so I am thinking I was taking pictures too late in the day.
I wanted the snake to be in overall focus, but going any higher than f/8 seemed dark. Then again with the higher shutter speed, it's no wonder. I will lower that next time.
Next time!
I love that there will be a next time since we have certain snakes that seem to hang around the house.
