So, I couldn't wait to get this lens. I finally bought it, and was so excited to put it to use. I quickly found that the focus at 1.8 is very soft.In my opinion, the value just isn't there. I mean if your paying double the price of the 28 2.8, you'd think it would keep sharp focus at the 1.8 setting, but it didn't. I'm just gonna buy the 2.8(which ive rented in the past, and loved) and be happy with my purchase.Needless to say I returned the lens a couple days later
