I agree...I had written off the 2x and f/14 as a non-starter. Until very recently, I've struggled a bit with the 100-500 + 1.4x and f/10. To me, f/14 seemed like it would be unusable. With much persistence and the right tools, I'm now getting good results with this combo and thinking (thanks to Alan) that f/14 may not be unreasonable.Nice Alan! now I am going to have to order the 2x LOL because IQ looks really good!
Ugh...I hear my B&H card calling me from the desk drawer.
