Canon RF 15-35mm F2.8L IS USM review: a pro’s staple wide angle zoom lens, but it’s not perfect
Canon RF 15-35mm F2.8L is USM: Two-minute comment
Ultra -wide -angle zoom lens is the necessary conditions for landscape, architecture, urban landscape and travel photographers. They not only enable you to capture a wide vision, but also to capture indoor decoration, but also allow you to approach the subject to exaggerate the perspective to obtain more dramatic results.
this Canon RF 15-35mm F/2.8L ISMMM is a professional ultra-wide-angle zoom that can provide multi-functional focus range, stable function and excellent image quality, which can stand out all content.
As a professional Canon L series lens, the price of 15-35 mm may make people ordinary enthusiasts. However, $ 2,400 / 2 2,400 / AU $ 3,500. Although the price is expensive, the price is relatively expensive, and the price of competitors’ F / 2.8 Ultra Ultra Ultra Zooms is relatively high, so the price is not surprising.
There are cheaper ultra-wide-angle zoom in the RF lineup. For many people, RF 14-35mm F4L IS usm will be more than enough, but it is not a faster F/2.8 maximum pores flagship option.
This is a lens, which aims to use the advantages of using advertising focal lengths on a full frame camera, although APS-C Canon users can still use the lens with an equivalent focal length of 24-56mm. Of course, this will not maximize all the benefits of the lens, but if you intend to upgrade to the full frame, it will make 15-35mm a valuable investment.
Throwing functions such as weather sealing, optical image stability, and minimum key distance, if you shoot any subject who will benefit from the professional lens who will provide such a wide -angle focus range, this will immediately become an interesting lens.
The quality of the image is generally great, but there are some warnings here, which becomes more and more common in the reflector -free lens. This is a serious dependence on the correction of the lens. Import the original file into Lightroom, and you will find that the lens is corrected by default. Close them, you will understand how powerful the adjustment of the application is.

Canon RF 15-35mm F2.8L is USM: Design
- Quite heavy lens
- Outstanding building quality
- Quick and silent autofocus
In terms of 15-35mm design, there is nothing to be excited, or it really disappoints. Well, when the expected weight ratio is 29.6 ounces/ 840 grams, when you think the size is almost the average of this type of lens, that is, 3.48×4.99 inches/ 88.5×126.8mm. However, the lens does maintain a good balance with the full -frame body when shooting the handheld.
I just think of the early promises, that is, no reflector cameras and lenses are less and lighter than their DSLR equivalent, and the tea I wrote will almost suffocate because it is not the case.
In addition to weight, 15-35mm is undoubtedly a high standard for your L series lens (including weather sealing) (including weather sealing), which is essential for aiming at the landscape and travel photographer’s lens.
The lens consists of 16 elements in 12 groups, including three distributions and two UD elements. In addition, it has an 82 mm fluorine coating anterior element. On the outside, there is an AF/MF switch, a image stable boot/turn -off switch, manual focus, and lens front lens control ring control ring.
If you think this is useful, you can program the lens control ring to adjust some settings in the camera. For me, this is useless and it is easy to be beaten, but this is my personal opinion, not a fact.

The lens has internal focus, so the front meta -component will not rotate, but the zoom is not internal, so the front of the lens extends from 35mm. The internal zoom will be more neat, but it will increase a lot of weight, not to mention that the ultra -wide -angle zoom within this focus range is common.
There is no manual aperture ring like many modern lenses, which is a useful function for photographers. In recent years, many lenses have provided traditional manual pores for this. Therefore, Canon’s flagship wide -angle zoom has missed a popular and useful feature, which is a pity.
Canon RF 15-35mm F2.8L is USM: performance
- Quick and silent autofocus
- Capture sharp images
- Constant f/2.8 maximum aperture
As a professional-specific lens, a 15-35mm lens has some functions that you expect in high-level Canon L series products. First of all, there is a constant F/2.8 maximum aperture. It is as effective as the lens under the installation of the lens under low -light conditions. Used for professional landscape and architectural images.
F/2.8 aperture can also be used for creativity and focus. This is the ideal choice for travel photographers. Although the aperture is not the best choice for celestial photography (larger choice is better), it must be available and further expands the potential of the lens.
Then, fast, silent autofocus, the minimum focus distance is 11 inches/ 28 cm. With a wide -angle lens, this may be great for creative shooting.

The quality of the image is generally excellent, with edge sharpness and the center of the frame. Although, as wide as you expect, the edge sharpness is lower than the central area.
The 15-35mm relies on lens correction to a large extent, whether it is a camera in the software when shooting JPEG or in RAW shooting. Considering the state of price points and professional series, I am surprised by the weight of the lens correction. However, the camera does produce wonderful sun exposure around medium aperture during night shooting.
When you load the raw file to Lightroom, you can delete both the color difference, and the open configuration file is corrected by default. Therefore, it must be programmed in the RAW file when shooting with a lens.
The switching lens is corrected, and a small illustration is even stopped to display the lens, and the light distortion pops up; a minor gun tube distorted at 15mm and 24mm, slightly plievant distortion at 35mm.
The color difference is small, but sometimes you can see along the edge of the contrast. The image is generally sharp and can be corrected with the lens, but you will be forgiven for the lens of this price and the louder L series label, because there is no application correction, you will expect more.

How do I test Canon RF 15-35mm F2.8L is USM
- Test with Canon EOS R1
- Shooting night and landscape photography
- At the same time, using handheld and tripod
Canon RF 15-35mm F2.8L IS usm is only available in the short loan of the Canon EOS R1, so the shooting time is very tight, and the weather difference will make the challenge more complicated. This means that most of my tests occur around the dusk, in order to use the late blue moment, and the daytime landscape lens when the weather is briefly cleaned.
Test various functions and functions, and the lens is specifically inspected any optical distortion. One of the main lenses I used with the camera is the high-level 16-35mm f/2.8, which provides USM for judging the basis of RF 15-35mm F2.8L.
These two lenses are made by different manufacturers, so they are different in many aspects, but it does provide practical expectations for function and performance.
