In what could be considered one of the best giao dịch for Canon APS-C shooters, the new Canon EF-S 10-18milimet ƒ/4.5-5.6 IS STM ultra wide-angle zoom lens is small, lightweight, very affordable &, as it turns out, quite the solid performer.

Canon already released an APS-C ultra wide-angle zoom lens -- the EF-S 10-22milimet ƒ/3.5–4.5 USM -- baông chồng in 2004, and earned a lot of praise for its image quality. However, it"s significantly larger, heavier và pricier than this new 10-18milimet lens, albeit a little faster with the ƒ/3.5-4.5 aperture range. As a compromise for the slower apertures, the Canon 10-18 features an IS system -- rated up lớn 4-stops at 18mm -- and combined with Canon"s STM focusing, this new lens should make it a hit with those looking for a small, fast-focusing lens as well as with HD-DSLR video shooters.

The 10-18mm, however, it not meant as a replacement to lớn the 10-22milimet. The small, lightweight build makes is a perfect pairing with Canon"s smaller, more entry-màn chơi DSLRs like the Rebel T5i or SL1, making a much more compact and convenient pairing when traveling. Based on our chạy thử results below, however, the new budget-friendly Canon 10-18mm lens is going lớn give sầu the older 10-22milimet lens a run for its money.

The Canon EF-S 10-18milimet ƒ/4.5-5.6 IS STM is currently available for purchase at the low price of $299 (ships with front & rear caps; a lens hood và soft carry bag can be purchased separately), & can be purchased at one of our trusted affiliates: Amazon, Adorama và B&H.

SharpnessDespite the appearance of a rather basic lens with a very affordable price tag, the Canon 10-18milimet lens is an extremely sharp lens -- even wide-open & at its widest focal length. At 10mm, the lens displays very sharp centers with only a hint of corner softness. In fact, it"s practically as sharp at ƒ/4.5 as it is stopped down khổng lồ ƒ/8! And it"s the same story in terms of sharpness at the other focal lengths as well -- very sharp images from wide-open to lớn around ƒ/11. Past ƒ/11, you can start lớn see diffraction take its toll on image sharpness, especially at the longer focal lengths. All in all, this is an impressive lens in terms of sharpness at all focal lengths, and even more so given its amazing price.

Chromatic AberrationThe new Canon 10-18milimet lens includes one UD element in its optical construction to lớn help combat chromatic aberration. However, despite this, CA is still noticeable at all focal lengths -- both wide open & stopped down to lớn ƒ/8 -- though only in the corners, which isn"t all that uncomtháng with ultra-wide lenses. Corner CA shows up as light green và purple fringing, which while present, should be easily correctable in post-processing. The center areas of our kiểm tra shots, however, display practically zero CA.

Shading (""Vignetting"")Like other ultra wide-angle lenses, vignetting is quite common, and on the Canon 10-18mm it is noticeable, particularly at the wider focal lengths. Wide open at 10mm, corner shading is over a full stop darker, và vignetting drops down 0.75EVs at ƒ/5.6 before finally reducing past 0.5EVs at ƒ/11 & onwards. The other focal lengths fair better at vignetting control, with wide-open shots showing maximum corner shading at a little under 0.75EVs. Stopping down to lớn ƒ/8 keeps vignetting right around 0.25EVs for all focal lengths except 10mm.

DistortionAs with vignetting, having some geometric distortion is not uncomtháng for wide-angle & ultra wide-angle lenses. The Canon 10-18milimet is not "off the charts" with barrel distortion, however, with 10milimet displaying under +0.5% of average barrel distortion. Out in the corners, distortion is more obvious however at just over +1% at 10milimet. As you zoom to lớn longer focal lengths, distortion, as you would expect, decreases significantly. At 14milimet, the average distortion is practically zero (và only slight maximum distortion out in the corners), but past that focal length, distortion is . negligible.

Focus OperationThanks to its STM motor, rear focusing system, high-speed CPU & an improved autofocus algorithm, the Canon 10-18mm lens focuses incredibly fast and very quietly. It took well under a second khổng lồ focus from minimum focusing distance to lớn infinity. Focus accuracy using our Canon 7D thử nghiệm camera was also very good, with no hunting, and it accurately locked onlớn the subject quickly.

For manual focusing, like other Canon DSLR lenses, simply flip the AF/MF switch on the left side of the lens (there"s also manual focus override available while in AF mode). The thin focusing rings sits near the front over of the lens. Manual focusing is a focus-by-wire system due khổng lồ the STM focus motor, meaning the ring rotates freely without stops at min. và max. focus distances, và the camera must be powered on in order khổng lồ actually adjust focus.

MacroWhile this is obviously not designed for standard macro photography, the Canon 10-18milimet does let you focus quite closely khổng lồ subjects with a minimum focusing distance of 22centimet (8.7 in.) for a 0.15x magnification ratio (1:6.7) when zoomed khổng lồ 18milimet.

Build Quality và HandlingFor $299, the Canon 10-18mm lens wasn"t going lớn be a premium, rugged, all-metal, weather-sealed lens. Typical of most EF-S lenses, it is indeed constructed almost entirely out of polycarbonate plastic, including the lens mount in this case. However, that"s not necessarily a bad thing. Avoiding metal construction, Canon saved a lot of weight, which, as Canon indicated, does make it a great companion lens with smaller DSLRs such as the T5i and SL1. The small size and weight also make it an easy lens to carry around when traveling. While the 10-18mm is certainly small by DSLR lens standards, it still accepts rather comtháng 67milimet filters, and does include Canon"s new pinch-style lens cap. (Nice!)

Despite being mostly plastic, the lens still has a high-chất lượng feel with a nice smooth blaông xã finish and a wide rubber-coated ribbed zoom ring (& thinner ribbed-rubber focus ring); much like the newer Canon EF-S 18-55milimet ƒ/3.5-5.6 IS STM kit lens. It still feels very solid in the hand, và the zoom action is very smooth without any wobbling from the interior barrel that extends ever so slightly when zooming. The two external switches -- the AF/MF switch and IS toggle switch -- are firm lớn move sầu and shouldn"t get accidentally switched easily.

The rest of the exterior is rather unassuming. There"s no focus distances markings or depth of field scale, và only a simple focal length indicators và 10, 12, 14, 16, và 18mm. The rest of the markings are various branding và Model name labels.

On the interior, the optical layout, as I mentioned earlier, includes one UD element for chromatic aberration control, và there are 13 additional elements, including one aspherical element, in a total of 11 groups. The elements feature multi-layer lens coatings for improved contrast, color balance & reduce ghosting. And there"s also a 7-bladed circular aperture diaphragm for smooth background blur.


The most obvious competitor to lớn the new 10-18milimet is Canon"s older EF-S 10–22mm ƒ/3.5–4.5 USM lens. At about $600, it"s certainly much more expensive, as well as larger & heavier. The aperture is faster at both ends with an ƒ/3.5-4.5 range, which helps explain the larger form size. Performance-wise, the two lenses are very evenly matched. It depends really on what you feel is more important: the slightly longer reach và the brighter aperture (10-22) or compactness, image stabilization and a bargain price (10-18).

There are other third-buổi tiệc nhỏ alternatives to the 10-18mm lens as well. Sigma has a couple of offerings, in fact, with a 10-20mm ƒ/3.5 EX DC HSM & a 8-16milimet ƒ/4.5-5.6 DC HSM. The 10-20milimet lens has a constant ƒ/3.5 aperture, and both vignetting và distortion are slightly better than the Canon 10-18milimet lens. However, corner sharpness & CA performance are not as good, nor is price at around $650.

The Sigma 8-16milimet ƒ/4.5-5.6 DC HSM is another APS-C ultrawide lens. Like the Sigma 10-20milimet, it"s also around $650, but provides a wider angle of view, without getting inlớn fisheye range. It"s also a solid performer in terms of sharpness, CA & vignetting, however distortion is high, especially at 8mm.

Lastly, there"s a Tamron 10-24mm ƒ/3.5-4.5 Di II LD SP AF option, that provides a similar 10mm focal length at the wide over, but also a slightly longer 24mm at the longer kết thúc for a bit more versatility than the Canon option. The brighter aperture range is also nice, especially with the lachồng of IS. The biggest downside, apart from the $500 price, is rather lackluster performance in the sharpness category, particularly with corner sharpness, & even when stopped down. CA and vignetting are also rather high.

ConclusionWith various other options from other manufactures, as well as another entry from Canon, APS-C shooters are certainly not without options for ultra wide-angle zoom lenses. The lakiểm tra entry inkhổng lồ this the category -- the Canon EF-S 10-18milimet ƒ/4.5-5.6 IS STM -- is the best bang for you buông xã for this type of lens. Extremely sharp with excellent AF performance, the $299 Canon 10-18milimet is a steal. Of course, you get what you pay for, as they say. This lens is made almost entirely of plastic, including the lens mount, but the upside is big savings in form size & weight... và price. This compact lens is the perfect option for Canon Rebel users, or any other APS-C Canon photographer, in need of a high chất lượng, ultra-portable, và ultra-affordable ultra wide-angle zoom.

The VFA target should give sầu you a good idea of sharpness in the center và corners, as well as some idea of the extent of barrel or pincushion distortion và chromatic aberration, while the Still Life subject may help in judging contrast & color. We shoot both images using the mặc định JPEG settings and manual white balance of our demo bodies, so the images should be quite consistent from lens to lens.

As appropriate, we shoot these with both full-frame and sub-frame bodies, at a range of focal lengths, và at both maximum aperture & ƒ/8. For the ""VFA"" target (the viewfinder accuracy target from Imaging Resource), we also provide sample crops from the center & upper-left corner of each shot, so you can quickly get a sense of relative sầu sharpness, without having to tải về and inspect the full-res images.
