It’s certainly a unique proposition. Canon EF 8-15mm Fisheye design, build quality and focusing. Measuring 83mm in length and 78.5mm in diameter at its widest point, the EF 8-15mm Fisheye is in fact Canon’s smallest lens in its ‘L’ range. It’s noticeably smaller than the EF 16-35mm f2.8L II and EF 17-40mm f4L zooms, and smaller even The sweet spot of the Canon EF 11-24mm f/4L USM lies around f/8. Wide open at f/4, there’s visible vignetting all around, which doesn’t go away until f/5.6. Vay Tiền Nhanh Chỉ Cần Cmnd.
