This was taken with the 70-200 f/2.8 ISL with both the Canon 12 and 25 extenders on. Manual focused. I was focusing on the stem on the first one and right above the flowering part on the second. Very difficult to focus.
Any thoughts would be great. This was my first outing with the extenders and I liked them. I tried them on the 24-105, but was nowhere near as impressed.
