for lenses below 1k etc , the price diff is about 100 -150 for sony style and street, but when you are talking about lenses above 2k , the street price can be more than $300 from rrp. If you're talking about a $500 lense like the 50mm 1.4 , the prices will not vary much.
I think the price diff for a $500 lens is about $40~50.... I really wonder why is there so much "generous" folk that would pay additional from the Sony Style Shop? Do they really provide much better services or installment plan? :dunno:
