Optical Limits posted their fuzll Canon RF 28-70mm f/2L review, and they underline the many virtues of this not-budget lens, of this outstanding lens. From their conclusion:

The Canon RF 28-70mm f/2 USM L is everything that you can expect from it – it is a monster of a lens with a monster performance. This is especially true for the broader center quality which is as good as on the best prime lenses. The outer image field is also superb in the lower zoom range. The corners soften a bit at 70mm but remain easily on a good level. That’s on a 45-megapixel sensor. On 20 to 30 megapixels, the lens is almost perfect. The native image distortions can be noticeable at 28mm but not an issue beyond. The native vignetting is quite high at f/2 but that’s no different from prime lenses. Auto-correction comes to the rescue in both cases, of course. Lateral CAs are absolutely negligible. The quality of the bokeh is good but there is a little room for improvement here. However, that’s complaining on a very high level really. The rather massive focus-breathing isn’t ideal for videos though.

The build quality is excellent which isn’t surprising given its professional target audience. The materials and assembly quality are top of the class. Weather-sealing is a natural feature at this price point anyway […] Read the review at Optical Limits…

Dustin Abbott posted his exhaustive Canon RF 100-400mm f/5.6-8 IS review. From Dustin’s conclusion:

[…] a truly portable lens that brings this incredible focal range into the kind of size and weight combination that many more photographers can cope with.

[…] For the money, this is a solid lens. It definitely has its limitations, but it pulls off this challenging focal range in a pretty convincing faction…and that small size might mean that even those with deeper pockets might pick one up just for the sake of its portability. This is a solid move for Canon, and the RF 100-400 IS is a lens I suspect will sell very well for them.

[…] it will also work fine for those that shoot action, birds, or wildlife in reasonably good light. The autofocus is quick and quiet, and I had no problem locking onto subjects. Just be realistic about the kinds of lighting situations that you’ll be able to get enough shutter speed to stop action, and you’ll be fine. I can see this lens being a “bridge” lens for many – the telephoto option they can afford now while they save (or hope) for a more premium option in the future. For the money, this is a solid lens.

As usual Dustin Abbott’s reviews come with sample images, comparison charts, and all the information you might want to know. Dustin’s reviews are what I look for when I am about to purchase new gear. As usual Dustin Abbott also releases a complete video review. See below.
