Very good shot. But without the close-up lens the DOF is larger and will get the entire rose sharp. I have the same gear but experience difficulty in sharpness with the 28-135 lens. Regards Rob.
I like the diagonal line formed by the roses and the muted background. The texture, because of your lighting, really shows through. (I'm riding Amtrak to Fresno Monday to get my bicycle overhauled. I won't be taking pictures, though. Strictly bike business.)
