In real world testing the sharpness at the edges of the frame when wide open on the older f/2.8 lens seems sharper at 16mm and softer at 35mm. Ironically, the inverse is the case for the f/4 which seems to be sharper in the center of the frame but softer at the edges at 16mm than the f/2.8, yet much better than the f/2.8 lens at 35mm.讓我驚喜的是,儘管焦距多 1 毫米,我用 RF15-35mm f/2.8L IS USM 拍攝的影像四角都比 EF16-35mm f/2.8L III USM 更清晰。 即使在廣角端, 色差和變形也較輕微 。 在相機拍得的原圖裡,色彩和對比度與 EF 相仿,但 RF15-35mm f/2.8L IS USM 朝向太陽拍攝時,在處理 重影和眩光
Review 1. Introducción. El Canon EF 16-35 mm f/2.8L III es un objetivo profesional, que ofrece una excelente calidad de imagen. Esta tercera versión tiene una óptica mejorada con respecto a la anterior y es más luminosa que el EF 16-35mm f/4L IS, aunque no está estabilizada. También es más cara, de echo ese es su principal inconveniente.
Canon has been on a roll of producing very well rounded lenses with strong performance as of late, and this lens is no exception. It is somewhat of a hybrid between Canon two previous L series wide angle zooms (the EF 17-40mm f/4L and the EF 16-35mm f/2.8L II), adopting the aperture of the former and the focal length of the latter. It also adds
Our review. The updated Canon 16-35mm F2.8L III offers some incredible performance wide open at 16mm. It's one of the sharpest wide angle zoom lens options on the market. Many of the issues such as coma, chromatic aberration and corner sharpness have all been addressed in this update and the results are impressive.Canon 16-35 F2.8 L II; Priced similar as option 1, I get a single-lens solution, but this lens has got some critical review since III version came, but third version is LOT expensive too. I am confused if this is good or better than Option 1, then I can simply get this lens for both astro and landscape usage. Option 3. Canon 16-35 F2.8 L III .
