Hello, I'm wondering if anyone could give me some feedback on using a Canon EF 500mm f/4L IS with a Canon Extender 1.4 II (My camera is a first version Canon 7D).
I only tried the extender a handful of times but was disappointed in the the image quality.
Thinking its...
- the equipment combination
- poor technique (I shoot mostly stationary birds from my car with a bean bag for support)
- something wrong with the extender
- or I'm expecting too much...
The 500mm without the extender is amazingly sharp. Cropped images without the extender look better to me (sorry, I didn't save any examples for comparison).
This image was taken without the extender: https://flic.kr/p/sp5DH2
Thanks!
