about canon 300mm f/2.8

<p>Jack:</p>

<p>When possible, I step down to f/9. That's my sweet spot with the 300/2.8 + 2x. I'm rarely one to test lenses. I generally shoot close to wide open. And I do when using the bare 300/2.8.</p>

<p>When I'm using the 2x, I spent time photographing wood grain patterns on my fence to determine that f/9 is sharper for me than f/8 and f/11.</p>

<p>So when the light permits, I'm shooting at f/9 with that combination.</p>
