if i could afford NIKON primes....I would not be living at home with my parents....and I have not had problems with my tamrons and sigmas.... at least i can have 2.8 zooms with them...
shot w/ older sigma 70-210 2.8 and a 2x ( quantaray ) converter on the d100... my parents got me...cause of a job op that did not happen...
I am not a pro or a business I cant write stuff off...
