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). Canon EF 16-35mm f/2.8L III USM Lens. Canon's Best Ultra-Wide Zoom Lens, Wide f/2.8 Aperture. There are many reasons to select this lens for your primary landscape needs, but the 16-35mm focal length range, containing some of the most desired landscape focal lengths, is one of the best reasons.

Canon calls this the Canon Lens RF28-70mm f/2 L USM. RF: Works only on Canon's EOS-R full-frame mirrorless cameras. L: Expensive as L. USM: Ultrasonic Autofocus Motor. Optics. Canon RF 28~70mm f/2L USM internal optical construction. Aspherical and UD elements. SWC sub-wavelength coating and ASC Air-Sphere Coating. 19 elements in 13 groups.
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. The new 16-35 f/2.8 III is sharper at f/2.8 then the f/4 is at f/4 for 16mm. That's much more impressive than I even dared to hope. Even at f/8 the new 16-35 III has a noticeable advantage in the corners. At 35 mm the two lenses are about equal wide open, but the III has a slight advantage at f/8 still. There is also noticeably less fringing
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. Tamron offers the stabilized 15-30mm f2.8 Di VC USD for about 1100 USD / 950 EUR. Its widest angle of view is 110 degrees but it lacks 5mm on the long end of its zoom range.

최대개방에서 16-35mm f/2.8L II와 심도 차이가 별로 나지 않는데다 2.8 III가 가격이 센 탓에 이쪽 구매자가 늘어나는 추세. 2.1.5. EF 17-40mm f/4.0 L USM [편집]

Canon RF 15-35mm F2.8L IS USM sample gallery. Designed from scratch for Canon's full-frame mirrorless system, the RF 15-35mm F2.8 is a fast, wide-angle zoom with built-in stabilization. As you'd expect from an L-series lens it's sealed against dust and moisture, and its stabilization is rated to an impressive 5 stops.
This is what the last users has tried to match. Sony Alpha a6700 + Tamron 18-200mm F3.5-6.3 XR Di II (motorized) Canon EOS 200D + Canon EF 35mm F2. Fujifilm GFX 100 + Canon EF 70-200mm F2.8 L IS USM. Nikon D5000 + Canon EF 24-85mm F3.5-4.5 USM. Canon EOS 1D Mark II + Canon EF 11-24mm F4 L USM.
The native-mount Sony FE 24-70mm f/2.8 GM Lens will be the head-on competition for these kits. In the Sigma vs. Sony comparison at f/2.8, the Sony shows as the modestly sharper lens at most focal lengths and also shows less lateral CA at 70mm. I see the Sony still holding the slight edge in the f/4 comparisons.
The Canon EF 16-35mm f/4L IS USM ($1,299/£1,389) was announced in May 2014. In February 2015, Canon announced the even wider and more expensive EF 11-24mm f4L USM ($2,899/£3,099). These lenses were followed by the EF 16-35mm f/2.8L III USM ($1,999/£2,199) in August 2016.

f/4.0,此时16-35mm f/2.8L III镜头达到最佳光圈——其实对于一支超广来说这个设定有点可怕,这也许意味着以后要获取极限画质,景深合成已经成为了一门必不可少的技术。. II代老款镜头中心解析力提高明显,但边缘仍然没能跟上。. f/5.6,III代镜头中心画质开始

24-70 f2.8 L II; 16-35 f2.8 L III; 16-35 f2.8 L III and retain the old 24-70 f2.8 L Series 1, in case it's worth it !) Thanks. K. The 16-35 / 4L IS is much smaller, lighter, and less expensive than the 16-35 / 2.8L III and for landscape photography, you'll likely be at f/5.6 or higher f-numbers. gbuG.
