The 135mm 1.8 is my FAVORITE. The 24mm 1.4 gets a lot of use and so does the 50 1.2 (because it has a unique look and it gives my bodies night vision). My most used lens is definitely the Tamron 35-150 f2-2.8, specifically for its focal range and speed. But the 3 above are my favorites (in the order I listed)

35mm or 50mm macro :)

14-35, 35, 85, 70-200, 400
