This is Tamron’s first lens for the Canon RF mount, the Tamron 11-20mm F2.8 RXD.

At a glance:

• APS-C | f/2.8 to f/16
• 18-32mm (35mm Equivalent)
• Fast Ultra-Wide Angle Zoom
• Rapid eXtra Silent Stepping Drive Motor
• 1x XLD, 2x GM Asph., and 2x LD Elements
• BBAR-G2 Lens Coating
• Weather-Sealed Construction
• Rounded 7-Blade Diaphragm

Dustin Abbott, on of the serious gear reviewers out there, felt the pulse of the Tamron 11-20mm F2.8 RXD for Canon RF mount. The review comes with sample pictures, test graphs, image quality breakdowns, and delivers all the information you might want to know about this lens. From Dustin Abbott’s conclusion|:

Like the Sigma 10-18mm F2.8, the Tamron isn’t cheap, costing twice as much as Canon’s own slower and plasticky RF-S 10-18mm. But it is also the superior optical instrument in build, function, and aperture speed.

Not everyone will want to spend over $600 for this lens, but those that do will find a lens that they will invariably enjoy, providing fast autofocus, good handling, and a very good (and consistent) optical performance. I’d say that it would currently be my choice, and that’s about as good a recommendation as I can give.

Pros:

• Finally a Tamron on Canon RF!
• Great wide angle zoom range
• Maintains F2.8 aperture
• Relatively compact and lightweight
• Good build with weather sealing
• Fast, quiet, and accurate autofocus
• Shares a 67mm filter thread with other Tamron lenses on Sony
• Exceptional optical performance
• Good coma control
• Strong aberration control

Cons:

• Relatively expensive compared to the Canon RF-S 10-18mm
• No aperture ring
• Corners lag behind the center a fair bit

This is the kind of review I read when I am looking to purchase gear. You’ll hardly find anything better.

Canon’s patent application 2024172507 (Japan, published 12/12/2024) , proposes an optical system with a unique design. It includes examples of compatible lenses, such as the RF 65mm F2 IS, RF-S 50mm F2 IS, and RF-S 85mm F2 IS, which cater to image heights slightly larger than APS-C.

Patent summary:

The primary objective of this invention is to create an optical system that offers exceptional optical performance, a wide aperture ratio, and a compact size.

In recent years, there has been a growing demand for optical systems that possess high optical performance, a large aperture ratio, and a small footprint. These systems are essential components in image pickup devices.

The patent presents an optical system with a positive, positive, and negative lens group arranged in a specific order, from the object side to the image side. The second lens group is designed to move during focusing, while the lens closest to the image side in the first lens group is positioned to correct image blur. However, a challenge arises when the lens positioned second from the object side in the third lens group has a convex surface facing the object side. This design makes it difficult to effectively correct coma aberration and similar issues when the aperture ratio is increased.

Example 1

• Focal length: 63.70
• F-number: 2.00
• Half angle of view: 18.76
• Image height: 21.64

Canon patent application 2024173039 (Japan, published 12/12/2024) discusses optical formulas for a bunch of full-frame lenses, from ultra-wide to standard.

Patent summary:

The present invention presents a compact zoom lens with exceptional optical performance, a high zoom ratio, and a small size.

In recent years, there has been a growing demand for imaging optical systems that combine high optical performance, a high zoom ratio, and a compact design. These systems are commonly used in imaging devices.

Example 1

• Focal length: 15.20-49.50
• F-number: 4.12-6.45
• Half angle of view: 52.76-23.61
• Image height: 20.00-21.64
• Total length: 124.63-125.93
• Back focus: 15.00

Example 2

• Focal length: 17.20-64.50
• F-number: 4.00-5.60
• Half angle of view: 49.30-18.54
• Image height: 20.00-21.64

Here is a weird Canon patent application for three pancake with rather slow aperture.

Canon patent application 2024172505 (Japan, published 12/12/2024) discusses optical formulas for three pancake lenses:

• 21mm F5.6
• 24mm F8
• 26mm F3.5

Summary of the patent:

This patent proposes an optical system that offers compactness while promising exceptional optical performance from the center of the screen to its periphery.

In optical systems employed in imaging devices utilizing solid-state imaging elements, such as digital still cameras and video cameras, there is a growing demand for lenses that combine compactness with good optical performance across the entire screen.

However, when the refractive power of each positive lens is increased to further minimize the optical system’s size, as outlined in the patent application, it becomes challenging to effectively correct the curvature of the field. Consequently, there is a risk that sufficient optical performance may not be achieved at the periphery of the screen.

Therefore, the primary objective of this invention is to provide an optical system that maintains compactness while delivering exceptional optical performance from the center of the image plane to its periphery.

Example 1

• Focal length: 21.40
• F-number: 5.60
• Half angle of view: 45.31
• Image height: 21.64
• Total length: 25.80
• Back focus: 12.00

• Focal length: 23.29
• F-number: 8.00
• Half angle of view: 42.90
• Image height: 21.64
• Total length: 26.00
• Back focus: 12.00

Example 3

• Focal length: 26.30
• F-number: 3.20
• Half angle of view: 39.45
• Image height: 21.64
• Overall length: 35.00

• F-number: 3.50
• Half angle of view: 37.62
• Image height: 21.64
