Someone in ProTalk DPR forum said this:
"Any lens that doesn't help me to make money is gone for sale!"
(...something like that, since I don't remember the exact words)
That's so true. I wish I can do that. And I believe that's what a pro should do NOT what a fan should do
I personally have the same thought of slimming down my lens collection.
Now I have a set of good zooms and another set of good primes.
Funny thing is at the beginning I love primes until I see my friend who shot Canon got so convenient with his 17-50 zoom.
Then I decided to buy some zooms.
Last time I met him, he told me that now he's buying more primes because of it's faster and better quality than zoom.
....what the heck!...I don't know if that's because he saw me using the primes or not but I guess it's true that the grass is always greener on the other side.
