Canon eos m 18-55mm đánh giá năm 2024

After a raft of critical reviews and user feedback reporting of tardy AF, Canon’s first mirrorless camera hasn’t been quite the success the firm envisaged. Nevertheless, Canon has since released new firmware enhancing the camera’s AF performance while at the same time dramatically lowering the price. As a result, the EOS-M is now a much more convincing option than it was at the time of its launch. Canon has yet to divulge a road map and so the strategy for cameras and lenses remains unclear, a fact not helped by the small group of lenses available (just three, including one prime). However, the $139 EF-EOS M mount adaptor allows the firm’s EF and EF-S lenses to be used without restrictions, making the tiny camera a more viable option for existing Canon DSLR users. The one zoom announced at the launch, the 18-55mm f/3.5-5.6 IS STM is stabilized and adopts the firm’s new stepper motor technology for smooth and near silent autofocus during video. The optical formula consists of 13 elements in 11 groups, focuses to 0.25m and is priced separately at $269.

This is the fist lens we’ve analyzed for the EOS-M mount, and with an overall DxOMark lens score of 13 points it’s rather good optically. Distortion, vignetting and chromatic aberration are all well controlled and sharpness is quite high for a budget lens but falls well short of a high-grade (and much more pricey) lens like the Sigma 18-35mm f/1.8.

With Canon now offering two APS-C systems, with the new ultra small EOS 100D DSLR targeting mirrorless cameras, the EF-M 18-55mm has a direct competitor in its own camp. Comparing the two reveals that the EF-M version performs very similarly to the slightly cheaper ($249) EF-S variant.

When we compare the EF-M model to rival offerings, the optical performance is on a par with the best kit lens from Sony for NEX series cameras. Even though the E 16-50mm f3.5-5.6 offers a wider angle of view (it’s the equivalent of a 24-75mm) that compromises optical performance somewhat, bear in mind it’s around $100 more expensive. Although, not a direct comparison based on sensor size, the Canon comfortably outperforms the $499 Olympus 12-50mm f/3.5-5.6 EZ lens, which is bundled with the maker’s high-end OM-D E-M5 model. Although it has other benefits, it’s not a great performer optically (for further comparisons of MFT standard zooms, please follow the link here).

Canon EF-M 18-55mm f3.5-5.6 IS STM vs. Nikon 1 NIKKOR VR 10-30mm f/3.5-5.6

We couldn’t help comparing the Canon lens with the Nikon 1 Nikkor VR 10-30mm (28-80mm equivalent). Ironically, the tiny Nikon 1 system is known for its impressively fast AF (with the Nikon cameras adopting on-chip PDAF). While this lens is also stabilized it’s accessibly priced at $186, and is frequently found as kit lens for the various Nikon 1 bodies. While most aberrations are well controlled it has disappointing sharpness, even when measured on a body with a relatively low pixel count (in this instance the 10Mpix Nikon 1 V1).

Canon’s prowess as a lens maker is just one of the attractions of the EOS-M system, however the firm seem reluctant to expand the system to appeal to enthusiasts. Be that as it may, with the price for EOS-M body complete with this lens now at just $345, compared with $899 at launch, it’s quite a tempting proposition.

The EF-M 18-55 3.5-5.6 IS STM came into my possession as part of an EOS M3 kit. Here's what I thought about this lens after a month of shooting.

Compatibility

The Canon EF-M 18-55 3.5-5.6 IS STM fits M series cameras like the EOS M, M3, M5, M6 and M50 MK II. It doesn't fit any Canon DSLRs or R series cameras.

Construction

This remarkably petite lens is an EF-M design and thus fits only Canon M series (mirrorless) cameras, e.g., EOS M, M10, M3 and M5. It will not mount on Canon DSLRS, e.g., 6D or Rebel T6i. Unlike the many cheap plastic zooms in this range, the EF-M 18-55 3.5-5.6 IS STM feels and looks like quality. This impression is largely due to the anodized aluminum barrel, knurled metal focus and zoom rings and metal lens mount. Plus, the barrel is nicely finished in a satin gun metal black. However, the nested inner barrel is plastic. The overall appearance is sleek and attractive, but with a hint of retro styling. The lack of AF/MF and IS switches contribute to the sleekness but require a visit to the menus to enable/disable AF or IS operation. At 210g it’s a feather light and easy to slip in a coat pocket or purse.

Auto Focus

Focus is internal—no front element extension or turning—and reasonably fast, but silent to onboard mics. And it can focus surprisingly close: photos of flowers and small products are a snap. The STM drive rendered pulls and Movie Servo silky smooth on the M3. I found STM focus equally effective for both video and stills. The electronic or "by wire" manual focus is smooth and well damped. Once enabled in the menu, manual focus works without flipping a switch. The gotcha is it only works when the camera is powered up with the shutter button half-pressed.

Zoom

The zoom ring is large, grippy and silky smooth in rotation. During zoom operation, a small nested barrel extends from the main barrel. The 18-55 range is only 3X, but covers the most useful focal lengths for general use.

Image Stabilizer (IS)

The integral image stabilizer gives me three stops of additional hand holdable range at 55mm when using an EVF with camera braced against my face. But the four-stops claimed by Canon is hit and miss for me. Somebody with a really steady hand might be able to squeeze out four stops. IS is quiet and isn't audible on video when using the built-in mic on an EOS M3.

Optical Performance

Wide open, this lens is sharp center frame but slightly soft in corners. Click down a stop and extremities sharpen up. Sharpness is consistent across most of the zoom range.

There's noticeable barrel distortion at the wide end and slight pincushion distortion toward 55mm. A click in DDP or LR quickly corrects barrel distortion. However, I was surprised barrelling is worse than the EF-s 18-55 3.5-5.6 IS STM that shipped with my EOS SL1. I assume they were similar designs but apparently not.

Chromatic aberration rarely seen but magenta fringing may be visible along high contrast edges. e.g., tree branches against an overexposed sky. Sharpness is comparable to my twice as expensive EF-s 17-85 4.5-5.6 IS USM, but the 18-55 has less distortion and color fringing.

Photos of sunsets, spotlights and other bright light sources were sharp with little flare (no filter installed) and no ghosting. Hood use is highly recommended to help protect from stray light and raindrops. Unfortunately, the Canon EW-54 Lens Hood is not included and is pricey at $25.

Mild light falloff (corner darkening) is visible wide open when shooting evenly lit such subjects as blue sky or white walls. It disappears as you stop down and, honestly, I don't notice it in normal shooting. If you shoot JPEGs, the camera's built-in Peripheral Illumination Correction feature automatically reduces light falloff. RAW shooters may correct with a few clicks in Lightroom or DPP.

Final Blurb

The EF-M 18-55 4.5-5.6 IS STM is an upscale variant of the least expensive and lightest APS-C normal range zooms available, but doesn’t disappoint optically. If you’re a EOS M series photographer, it’s a marvelous featherweight zoom for snapshots and travel. And that’s a good thing since there are so few lens choices for this little camera.
