I am planning to buy "Canon 100-400 mm f/4.5-5.6 IS USM" Lens for Wildlife photography.
Any feedback on this lens will be helpful for me.
Although the Canon 300mm f/4 has better optical quality than this lens, I preferred to take the 100-400 mm lens for it's versatile zoom range.
I am expecting that even though it's a slow lens, we can get good quality shots with higher ISO with cameras like 40D.
