I haven’t upgraded my photo gears for 5 years. Especially in a condition when a telephoto lens is required, I feel my capability to capture the scene is limited because my current 75-300 f/4-5.6 lens could only do f/5.6 at the long end. I finally decided to buy a Canon EF 70-200 f/2.8L IS USM lens as an upgrade.
This is the first L-serial lens I owned. Besides the glass quality, the fastness of the USM driven auto-focus and Canon’s IS feature give you 3-stop stability for hand-hold shooting. The only downside would be its weight. I took some pictures with this len and switched my previous len for comparision, then I realized how heavy this powerhouse is.
Here are some random snaps to compared these two telephoto zoom lens, (although it might be unfair to compare a $200 piece with a $1800 one) . The one on the left or top were taken by 70-200 F/2.8L; the other is by 75-300 F/4-5.6.
