But I have to wait until I can run Lightroom later this evening to check what focal lengths I use most and etc. I do love primes and I am addicted to 1.4 - do you think this would be a bad move? I would probably replace the Beast later down the line with the 35-70 2.8, but for now I would just have my Sigma Dirty Thirty and my shuffling feet to cover the focal lengths the beast covers for me now. I don't know. I might not be thinking straight.....NAS has got the best of me!
