Bryan at The Digital Picture has completed his review of the brand new Canon RF 15-30mm F4.5-6.3 IS STM, Canon's ‘value' wide angle zoom lens for full-frame and APS-C RF mount cameras. If you're like me, you may only use an ultra-wide angle lens on occassion, so this is a great option for minimal cost compared to the RF 14-35mm f/4L IS USM Canon EF 16-35mm f/2.8L III USM Canon EOS-1D X Mark II Canon EOS 100D Canon EOS 1Ds Mark III Canon EOS 20D Canon EOS 30D Canon EOS 350D Canon EOS 400D Canon EOS 40D Canon EOS 450D Canon EOS 500D Canon EOS 50D Canon EOS 550D Canon EOS 5D Mark II Canon EOS 5D Mark III Canon EOS 5D Mark IV Canon EOS 5DS R Canon EOS 700D Canon EOS 70D Canon EOS

6 days ago · The Canon RF 15-35mm f/2.8 L has remarkably low levels of distortion for an ultra-wide zoom. Here’s a chart showing the distortion from 15mm to 35mm: The lens maxes out at just -1.03% barrel distortion at 15mm and 1.83% pincushion distortion at 28mm. This is much lower than typical ultra-wide zooms, which are some of the most distortion-prone

At 5.5 stop 14-35 is 0.5 stops better than 15-35, if no fast motion and DOF was not important this can make the 14-35 just 0.5 stop darker. 2. Better magnification. At 0.38x 14-35 is almost 2 times better than 15-35 at 0.21x making it capable of creating UWA macro shot that very few lens if any can do.

The resolution test of the Canon 16–35 mm f/4L was based on RAW files from the Canon EOS 5D MkIII which has replaced our worn-out EOS 1 Ds MkIII. Fortunately the pixel density of both sensors is almost the same so the MTFs you get are practically identical. In the case of both cameras the decency level is situated near 30-32 lpmm and the best
All-in-all the lens is capable to beat the cheapo EF-S 18-55mm as well as the EF-S 17-85mm IS and regarding sharpness it can even rival the the EF 24-70mm f/2.8 USM L (on APS-C). If the focal length range was more attractive here the lens would have been a killer but as such it is just a good compromise.

The RF 15-35 has dramatically less barrel distortion and lateral CA. The Canon RF 16mm F2.8 STM Lens vs. Canon RF 15-35mm F2.8 L IS USM Lens comparison shows the prime lens to be dramatically smaller and lighter than the zoom. Correspondingly, the RF 16 uses smaller filters (43mm vs. 82mm) and has a higher maximum magnification (0.26x vs. 0.21x).

From a sweeping ultra-wide 15mm to a "wide-standard" 35mm, the Canon RF 15-35mm f/2.8L IS USM lens could be the perfect travel/architecture/street companion, especially with its fast f/2.8 maximum
The first thing to notice is that the the 17-40mm vignettes somewhat more than the 16-35mm at f/4. Not a lot, but noticeable. But the 16-35mm appears to show more flare and lower contrast at this aperture and focal length. Canon 17-40mm f/4L @ 17mm @ f/4 @ 100%Canon 16-35mm f/2.8L @ 17mm @ f/4 @ 100%.

The same lenses are shown below in their fully extended states with their lens hoods in place. As indicated in the chart above, no provision is made for the Canon EF 8-15mm f/4L USM Fisheye Lens to accept front filters. The Canon EF 20-35mm f/3.5-4.5 is a very lightweight full-frame ultrawide zoom for all Canon EOS digital and 35mm autofocus cameras. This 20-35mm has fantastic ergonomics. Nothing moves externally as it's zoomed or focused, and all the controls are exactly where they should be and feel great. This 20-35mm has instant manual focus override JWiRtH0.
