I have a Love/Hate relationship with my Sigma 70-300mm. Its not IS which bugs me a bit. But, I feel like maybe half of my hatred for it is simply because I don't use it as much as my other lenses. I primarily shoot with my nifty fifty. Its my absolute favourite for a variety of reasons.
So, the rest of this week I'm going to used my 70-300 every day and see if I can learn to love it, or if I want to let it go down the road. So tonight you get Root Beer because I was playing with the macro range.
