Canon “RF24mm F1.8 MACRO IS STM” pre-release review that allows you to enjoy “wide-angle macro” lightly

On August 26, 2022, Canon will release two new models of the interchangeable lens “RF lens” for the mirrorless camera “EOS R system”. One is the compact and lightweight wide-angle single focus lens “RF24mm F1.8 MACRO IS STM”, and the other is the ultra-wide-angle zoom lens “RF15-30mm F4.5-6.3 IS STM”. All of them are standard type (popular type) lenses, and they are products with a good balance between price and performance. In this article, let’s quickly review the wide-angle single focus lens “RF24mm F1.8 MACRO IS STM”.

The “RF24mm F1.8 MACRO IS STM” is a wide-angle, single-focal lens that is positioned as a standard type in Canon’s lens lineup. Canon’s lenses are famous for their high-performance and robust “L lenses” for professionals and high-end amateurs, but the standard-type lenses are not as good, but have sufficient image quality and functions for practical use. It is a product that has gained support from a wide range of users, including entry-level users, with a price that is easy to hold and affordable.

The first feature of the “RF24mm F1.8 MACRO IS STM” is its size. While achieving both a wide angle of view with a focal length of 24mm and brightness with an open aperture value of F1.8, it is compact and lightweight with a size of 74.4 (maximum diameter) x 63.1 (length) mm and a weight of approximately 270g. As for how compact this size is, the total length of about 63.1 mm is among the full-size compatible focal length 24 mm / open F1.8 lenses registered on Kakaku.com as of August 19, 2022. Shortest. Weighing approximately 270g, it is the second lightest 24mm/F1.8 lens and the lightest as a camera manufacturer’s genuine product. All genuine 24mm/F1.8 lenses are over 70mm long and weigh over 300-400g. You should be able to see that the weight has been reduced.
In terms of functionality, it is the smallest and lightest in its class, but its main feature is that it supports half-macro shooting with a maximum shooting magnification of 0.5x. The shortest shooting distance is 14cm (0.14m), and it is possible to get close to the subject as close as 4.2cm from the tip of the lens. It is possible to take wide-angle macro photos that emphasize perspective by taking advantage of the wide angle of view to capture the surrounding scenery while getting close to the main subject.
Among the “RF lenses”, the “RF35mm F1.8 MACRO IS STM” with a focal length of 35mm is famous as a “compact and lightweight single focal lens for half-macro photography”. This lens was released in December 2018 with the birth of the “EOS R System”, and is highly rated by users for its excellent image quality. As of August 19, 2022, Kakaku.com user review satisfaction is “4.72” (43 review posts), which exceeds the category average of “4.59”. The “RF24mm F1.8 MACRO IS STM” introduced this time is designed with the same concept as this “RF35mm F1.8 MACRO IS STM”, and the sense of size is quite close. For those who know the good image quality of the “RF35mm F1.8 MACRO IS STM”, it can be said that it is one that has high expectations.
The optical design consists of 11 elements in 9 groups, including one “plastic molded aspherical lens” that is effective in suppressing spherical aberration and distortion, and one “UD lens” that suppresses color bleeding with low refraction and low dispersion characteristics. , Reduces various aberrations that cause image quality deterioration and achieves high image quality.

In addition, the effect of camera shake correction is about 5.0 steps with the lens alone. When attached to an EOS R series camera equipped with in-body image stabilization, cooperative control provides an effect of approximately 6.5 steps.

In addition, this lens adopts a design that assumes electronic correction, like the super wide-angle single focus lens “RF24mm F1.8 MACRO IS STM”. Distortion correction is automatically turned on when the lens is attached to the camera, and the user cannot turn it on or off, including during RAW development in the camera. Canon’s genuine RAW development software “Digital Photo Professional 4” also automatically applies distortion correction (even when correction is turned off). Also, like other electronically corrected lenses, this lens is not compatible with multiple exposure shooting with “EOS R5/R6/R/Ra/RP” (* “EOS R3” is compatible).
Live-action example & review
The example posted below is a combination of “EOS R5” and “RF24mm F1.8 MACRO IS STM” taken at the highest image quality in JPEG format (JPEG shooting). In all the examples, the settings are Peripheral Illumination Correction: On, Distortion Aberration Correction: On (Automatic), and Digital Lens Optimizer: On (Standard).
