I have both Zooms(24-70,70-200mm) & Prime (100mm macro) EF Canon f2.8L lens these are great outdoors specifically the 24-70 f2.8L @ f4.0 - 9.1 , very sharp.
Have a look a the Sigma Primes , I have a 50mm f1.4 not very expensive at least compared to Canon "L" lens very sharp @ f 2.0 - 2.4.
The Sigma surprised my the most , the quality is equal to Canon . I shot my last doc. with it , In fact I use it most of the time for internal shots now.
Great low light performance for the price point.
