Here is a new Canon RF 28-70mm f/2L review. The RF 28-70mm f/2 is one of Canon’s “boutique lenses” for the EOS R system.

At a glance:

• RF-Mount Lens/Full-Frame Format
• Aperture Range: f/2 to f/22
• Ultra-Low Dispersion Elements
• Ring-Type Ultrasonic Motor AF System
• Customizable Control Ring
• Rounded 9-Blade Diaphragm

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…

• Aperture Range: f/5.6 to f/45
• One UD Element, One Aspherical Element

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.

Here is a Canon RF 14-35mm F/4L IS review. A rather enthusiastic review, we might add.

At a glance:

• RF-Mount Lens/Full-Frame Format
• Aperture Range: f/4 to f/22
• Three UD Elements
• Three Aspherical Elements
• Air-Sphere and Fluorine Coatings
• Nano USM AF System
• Optical Image Stabilizer
• Customizable Control Ring
• Rounded 9-Blade Diaphragm

ePhotozine posted their full Canon RF 14-35mm F/4L IS review. They gave the lens a 5/5 rating and an “editor’s choice” mention. From their conclusion:

Some lenses just gel and just get on with the job, performing flawlessly and smoothly and not getting in the way of image-making. This is such a lens; what a beauty it is and what lovely results it delivers.

The extra 1mm compared to the existing 15-35mm lens should not be underestimated, as such a difference is much more significant in an ultra-wide than, say, the difference between a 100mm and 105mm lens would be. The loss of 1 stop of speed does mean a lighter, more compact lens that also costs significantly less. This makes a good choice for travel photography.

In summary, a superb offering from Canon and without doubt an ‘Editor’s Choice’.
