New EF-M mount lenses have sầu been fairly few & fair between, but năm 2016 saw two very solid lenses released: the EF-M 28milimet f/3.5 Macro IS STM lens (my Đánh Giá here) and this lens, the Canon EF-M 18-150milimet f/3.5-6.3 IS STM. The 18-150 STM is both similar and different to past EF-M zooms. It is similar in the sense that it is another variable aperture zoom lens (Canon has favored these “slow” lenses for the system due khổng lồ their small kích cỡ & weight), but different in that it provides more of a genuine all-in-one solution than what the system has previously seen…at least from Canon. Tamron has had a very competent 18-200mm option for the system for several years (I reviewed that lens here), though it is worth noting that it is about một nửa heavier than this lens và is currently not compatible with the EOS M5 until a lens firmware update is released (Tamron had a similar issue when the M3 was released but was able khổng lồ fix it via firmware). Update: the firmware update was released on January 17th. Contact your local Tamron distributor lớn receive the firmware update.

But Canon’s own all-in-one solution is here, & the18-150 STM is a very compelling lens on a lot of levels.

Prefer to watch your reviews? I’ve got you covered. Click the đoạn Clip below to see my video clip nhận xét of the EF-M 18-150milimet STM.

I used the 18-150 STM extensively while on a extended trip lớn Arizona as well as here in Canadomain authority. I used it in a wide variety of settings & got a good sense of its capabilities. Read on to lớn find out more!

Build & Design

In this video I break down the overall build, thiết kế, và features of the lens. It will give sầu you a good sense of the lens itself.

The 18-150 STM essentially borrows the body toàn thân from the 55-200 STM. They are physically near identical. They are both 2.4” (60.9mm) in diameter, và one is 3.4” (86.36mm) while the 55-200 is 3.41” (86.5mm) long. That fraction of a milimet is imperceptible. What is perceptual is the difference in weight. While both are light, the 18-150 STM feels a little denser at 10.6 oz (301g) vs. 9.17oz (260g). This is due to lớn the 18-150 STM having a slightly denser optical formula. Both have sầu 17 elements, but they are in 13 groups rather than 11 in the 18-150 STM. Both have seven rounded aperture blades.


The 55-200 STM is optically impressive, but the one thing I’ve sầu lamented is its somewhat uninspiring minimum focus distance (3.28 feet or 1 meter) & the resulting pedestrian 0.21x maximum magnification. It just often feels lượt thích you should be able khổng lồ get closer than you can. The 18-150 STM solves that problem by cutting the minimum focus distance in half (1.5 feet or .45m) & thus getting a much more satisfying 0.31x maximum magnification despite having a shorter maximum focal length. This near 1/3rd life kích cỡ figure adds a LOT of versatility lớn the lens, và it seems lớn perform quite well near minimum focus. Here’s a look comparing the magnification of the two lenses:


I will note that the build quality of Canon’s EF-M lenses has declined since the release of the 18-55mm STM, 22mm STM, & 11-22milimet STM lenses. They feel a bit more plasticky now, and have sầu plastic lens mounts rather than the metal ones employed on the earlier lenses. I used khổng lồ be able to lớn say that the EF-M lenses were better made than their EF-S counterparts, but that’s not really the case anymore. For those keeping score, this lens says, “Made in Malaysia” stamped into the mount.

Autofocus and Image Stabilization (STM + IS)

The 18-150 STM employs Canon’s STM or Stepping Motor công nghệ. This was originally designed more for smooth focus changes for Clip servo AF, but has become the de facto focus system for all of Canon’s EF-M mount lenses lớn date. STM technology continues to lớn excel more at smoothness than tốc độ, though focus speed is pretty decent here. Focus changes on the wide over are near instantaneous (depth of field is much greater, thus focus changes are smaller), and while the speed slows down a bit at 150milimet, in good light it is still extremelyquichồng. In dlặng light it needs a little more time, while the wide end remains extremely fast. I used the lens extensively while at the new OdySea Aquarium in Scottsdale, Arizomãng cầu. The dyên light, shooting through glass, & trying to traông xã movement did expose a few limitations, but overall the lens (và the EOS M5 toàn thân I was using it on) mostly allowed me lớn get what I wanted. There were a few moments that I wished for a DSLR và a different lens in my hand, but they were fortunately rare. Here’s a few of the photos I was able to get with this combination while there.
