I am looking to purchase 2 of these lenses in the next week or two. I am pretty set on the 50 1.4 and 85 1.8. I have used the 85 before and loved it immensely. I am wondering if I should consider the 35 f2. I have the 5dmk2 and 50D so my only concern is that when considering the 50 and 85 and the crop factor, I really of 3 focal lengths to choose from. But if I had the 35 and 85, I will have 4 focal lengths. Maybe a better value. Any thoughts? Hands down I will not go with the 35 f2 if people here say that its quality is worse than the 50 1.4. I am not just looking at focal lengths.
