<p>Tim, in thinking about this before posting and coming up with WTF?? (sorry about the language) I posted my question. Thinking about it today, it could be lack of going out and shooting often, thus not looking at shutter speed although I do remember looking but I was shooting at too low shutter speeds. The 70-200 is still heavy in my hands and focusing with the shorter lens seems to give me a hard time. I also forgot to use my 50 1.4 which might have been very useful. Again, not enough shooting.<br>
"he still can't distinguish between a shot affected by out-of-focus vs camera shake" For me, it's not always that easy.</p>
<p>"And didn't test first to narrow down the cause." Not sure what you mean.</p>
<p>I can't seem to find the post that factored in the APS-C sensor in the reciprocal of the lens length speed rule. Using that would probably have saved a few shots.</p>
<p>Any other thoughts? Hopefully, if I shoot with her again, I'll be able to post a few on the POTW.</p>
