so im looking into the UWA/fisheye market for a nice really wide lens in the no more than $400 range. i am ok with full manual lenses and shoot mostly sports and event photos at my school. i am having trouble deciding and do not have the resources to rent or borrow. i want to save as much money as possible since it will not be my primary lens anyway, i shoot sports with my sigma 30 and 50 1.8 (basketball) and for all other sports i have a 70-200 2.8 mkII +1.4X extender
what i am considering so far:
rokinon 8mm fisheye
rokinon 14mm f2.8 (might not really be that wide on my crop so not top pick)
sigma 10-20 f4-5.6 *used if i can find one
canon 10-22 *used
are there any other lenses out there that i am missing within the $400 or less range?
