the 1.8 has 7 blades aswell^
I just like being forced to be more creative with the one focal length, And if thats going to replace 2 lenses, I want it to be a great lens.
I just never use the 18-70

If im shooting cars its either the 10-20, 50, or the 80-200.
The new AF-S 50mm 1.4g is just amazing, so ill probably pick that up. Fast primes are where it's at. Who knows I might just sell this and save up for some FF action
