<p>Thanks for your opinions. You're right. Maybe I don't really need a new lens. I was just looking for additional sharpness and bokeh in some of my portraits. The Sigma 17-50 is very versatile and is my walk around lens, but it doesn't deliver the results I was looking for. After all my reading and also your comments, I'm still leaning towards the 85 1.8. I've seen great results with the 7D + 85 1.8 combination. Anyways, I plan to use this lens only for outdoors. I know that indoors will be very difficult. I kind of like getting a longer lens too for maybe family weddings, concerts, etc. The other attractive option is the Sigma 35 1.4 but that is $900 while the 85 1.8 is $369. So for the money, I probably go with 85. Maybe I can rent it too and see if it fits my needs. <br>
Thanks again to all! I really value your recommendations.</p>
