Thanks @lavenderblue! I haven't worked with digital Canons (only Nikons and Fujis), but I agree that given that motion techniques are relatively subtle, they work best with a camera that we're familiar with and are used to all its little quirks. While a new digital camera can have a ton of features, if may not be suited for every purpose.
In any case, I'm happy to have discovered your feed via your kind comment.
