Also DXOmark tests ( with 5D3 ) indicate for the EF 35mm f1.4 L II, a T stop of T 1.7 the EF 35mm f2 IS a T stop of T2 . Very little actual light transmission difference. For the f1.4 L II lens the sharpness is 18 mp. For the f2 IS lens the sharpness is 20 mp. Slightly better for the f2 lens. For the f1.4 L II the vignetting is 2.2 ev.
细节 新涂层 可使用圆形滤镜. 接下来我们来看看佳能新EF 16-35mm f/2.8L III USM的更多细节设计,新EF 16-35mm f/2.8L III USM在外观上明显比前代要长出一些,这是因为全新的光学设计所带来的结果,可以说如今画质和便携性之间还是很难取得太好的平衡,为了更好的画质,牺牲一定的便携性仍然是必然的结果。
Canon has the stabilized EF 16-35mm 4.0 L IS USM from 2014 (980 EUR) and the EF 16-35mm 2.8 L III USM from 2016 with a street price around 1950 EUR.

Such high vignetting we haven’t seen so far in our tests. At 16 mm and by f/2.8 in the frame corners disappears 75% of light (−4.07 EV). On stopping down the aperture to f/4.0 the situation improves but still the vignetting remains very high, reaching 57% (−2.47 EV).
Dedicated to the Canon EF 16-35mm f/2.8L III USM lens, the EW-88D Lens Hood helps to minimize flare by deflecting stray light from entering the lens. The hood also provides additional protection to the lens from accidental impacts, bumps, or scratching. It is offered here as a spare or replacement for the hood originally included with the lens.
