    Sigma 500mm F4

    Priced too close for comfort in making a truly compelling argument as an alternative given the roughly 10% extra weight it carries? ..... I had hoped for keener pricing than that ..... :cat: Chosun :gh:

    Sigma 500mm F4

    Proper 500mm f4, $6K, 380mm long, 3310grams, hmmmm ..... :cat: Close enough weight wise, yet not as expensive as the CaNikons, to be a consideration ??? Wonder if the iq and AF will be comparable ?? ....... :brains: Chosun :gh:
