Gosh, I am not faithful to any particular lens. I have different moods and some shots need a different focal length and I change lenses accordingly.
I have always loved the versatility of my 24-70mm 2.8 lens, one can shoot most things with this lens. The 70-200mm 2.8 is just amazing and I love the cinematic feel of this piece of glass. Then there is my 14-24mm 2.8. It also has a time and place and I love the feeling of space it creates. I have two fixed focal lenses, the 50mm 1.4 and the 85mm 1.4. I enjoy using these for portraits.
