Ben, congrats on the new toy. I can't wait to see some street shooting in Paris with this lens from you. We're expecting a thread full of images in a week or 2.
I tried this one out for an hour not long ago and it's on my list. I already have the range covered but for the size and weight, plus the low cost, you can't beat it.
I recently got this months issue of "Outdoor Photographer" magazine and in it was an article about "what's the best Tele zoom for you". They had pros opine their favourite lens.
Kerrick James carries the DA50-200mm which I found very surprising. It's a nice lens but I've had one and there's better glass out there. But who the hell am I? He's published and makes his living at this. Web page:

James Shadle uses the same lens you just bought. His "big gun' is a 600/4 but he seems to really like the 70-300 and his work speaks for itself. See his web page:

I'm sure you'll enjoy it and we look forward to the results.
BTW the 1:2 macro on this lens is very cool. You can get some very good macro shots and still stay far enough away from the subject to not disturb anything.
I can see it now.... The new web page will be called "Ben's Bee's 'n Bug's"
