Teleobbiettivo in ottime condizioni, leggero ed ottimamente corretto, TAMRON 300mmF/2.8 LD-IF attacco Canon Eos per FF. In pratica un astrografo, correzione al pari (o meglio secondo molti) degli equivalenti Canon e Nikon, con un peso minore. Vendo per setup differente. Da una review in lingua: Fast-Aperture Telephoto Lens, Model 60B: This lens has a revised optical design compared to Tamron's earlier Model 107B, features internal focusing (IF), and features two low dispersion (LD) elements which are shown in green in the above optical layout. The addition of internal focusing required the addition of three additional internal lens elements for IF plus a redesign of both the front and rear optical groups. This lens is slightly sharper and has significantly higher contrast compared to the earlier Model 107B. Like the earlier 107B, this lens has very slight amounts of off-axis lateral color and coma, but these off-axis aberrations have been greatly reduced. Overall, this is a very sharp lens with performance which was not easily surpassed by similar OEM lenses of the era. Optical performance compared to current 300mm F/2.8 lenses is good to very good.
