The best advice I got about getting another lens came from someone at B&H during a webinar. They encouraged me to rent the lens I was interested in and play around with it before purchasing it. I looked online and it’s pretty easy to find places you can rent from. Some will even ship them to you. I am still really new to photography but will be taking this advice once I’m ready to invest in a second lens. I have the same camera and lens that you do. Hope this helps, I think it’s a great option before spending money on a lens and then finding out you would have liked another one better.
