Canon’s other kit lens for APS-C EOS R mirrorless cameras, the RF-S 18-45mm F4.5-6.3 IS STM ($299.99), is replaced with the more expensive RF-S 18-150mm F3.5-6.3 IS STM ($499.99). Naturally, the 18-150mm is a bit more expensive and larger, but we believe those trade-offs are worthwhile. Particularly for a lens that you are likely to use for daily photography, the increased zoom range and superior macro performance are important advantages.

AN EXPERIENCED LENS FOR SOME You may be aware with the 18-150mm F3.5-6.3 IS STM designation because Canon created an EF-M 18-150mm F3.5-6.3 IS STM for its EOS M camera system. The RF-S and RF-M versions, according to DPReview, share the same optical diagram and MTF performance charts (Opens in a new window) . Given that the Canon EF-M 18-150mm was a competent entry-level zoom when we evaluated it, we won’t criticize the company for using an established optical design in this case.

As seen below, the barrel telescopes to zoom. You only get the front and rear caps with the lens; you might wish to add a 55mm filter to shield the front element from scratches and errant fingerprints. As an alternative, you can purchase a third-party hood (for as low as $10) or the Canon EW-60F hood (around $30).

The optical formula for the 29-240mm, which was originally created for the compact EOS M line, is deceptively modest in full-frame terms, but this is to be expected. Only the zoom ring and manual focus ring are available as on-barrel controls. The zoom, which takes up the majority of the barrel, has a ridged plastic finish. The focus ring is located in front of it; it is reasonably narrow and has a rough, diamond-like structure.

The STM motor’s advantage of silent, smudge-free autofocus. The compact optics quickly switch between close-up and distant focus. However, the manual focus experience isn’t excellent. The throw is relatively brief, and because of the nonlinear reaction, you must move very slowly and deliberately to make exact corrections. In general, we advise sticking with autofocus.

Imatest (Opens in a new window) displays extremely decent resolution (approximately 3,000 lines), with significantly improved clarity between f/5.6 and f/8 (around 3,300 lines). Edge clarity isn’t ideal at the wide end and is still a little soft when stopped down, but given the lens’s size and 8.3x zoom ratio, this is to be expected.

The R10 with the 18-45mm costs $1,099, but the 18-150mm kit costs $1,379—a $100 savings over purchasing the camera and lens individually. You could disagree with our assessment if you’re on a tight budget or prefer the 18-45mm’s incredibly compact form factor.

The RF-S 18-150mm is the only kit lens available to potential EOS R7 customers, leaving them with no other options. (With this combo, you receive the same $100 discount on the lens.) Although we thought the lens worked well with the R7, we recognize that designers looking for an upscale camera would prefer a normal zoom with a broader field of view or a brighter maximum aperture.
