The EF-S 15-85mm F3.5-5.6 IS USM is a work of amazing plastics and has a strong vibe to it. The lens mount is all metal and along these lines significantly less inclined to wear than traditional plastic mounts. The lens is not fixed against moisture or dust and no embellishments (other than the lens top and dust cap) are incorporated. Be that as it may, a decent lens hood is accessible for buy and it has the same pleasant top-of-the-line looks.
As to the lens’ size and weight, it truly relies on what you contrast it with. There are lighter and smaller lenses that offer comparable central lengths but not at the same level of picture quality (which unavoidable needs heavier or more glass). Then again in the event that you contrast it with its full-frame “equal” (the EF 24-105mm F4 L USM IS), it is obviously lighter and smaller – yet that is not a reasonable examination either.
The handles and rings are firm keeping in mind the zoom ring is generously estimated and the focus ring is quite little. The lens does not have a zoom lock switch and doesn’t bother with one on the grounds that the zoom has the right contact to oppose gravity zoom augmentation while permitting exact operation.
The EF-S 15-85mm F3.5-5.6 IS USM highlights a cutting-edge ultrasound sort autofocus motor that is brisk, quiet and precise. Without the need to change over to MF mode it permits you to physically override the autofocus operation whenever.

The lens is sharp to the corners even with a completely open aperture. Corner execution is marginally weaker from 50-70mm with a totally open gap, yet at the same time not terrible. The EF-S 15-85 demonstrates a slight change in sharpness when ceased down to F8, all things considered, little change is required.
The lens additionally indicates incredible execution all through the mid-extent and telephoto scope of focal lengths.
Chromatic Aberration is very much controlled by the lens, especially somewhere around 24mm and 70mm. At 15mm and 85mm, chromatic aberration results are actually noteworthy. At 15mm chromatic aberration shows up a bit in the corners regardless of the opening; at 85mm, chromatic aberration is more unmistakable as the lens is ceased down.
Shading or ”Vignetting”:
Corner shading is genuinely noticeable with this lens. At 15mm, corner shading is an element paying little mind to the aperture chose, however, is most noticeable when utilized completely open at F3.5; at this setting, the corners are just about a full stop darker than the middle. This enhances a half-stop by F5.6, and consequently, corner shading is dependably a variable.
At other central lengths, vignetting is just an element at F8 or more extensive. At these settings we see a half-stop or less when the lens is utilized totally open at 24mm or 35mm; at different settings, corner shading is not an issue.
Likewise, with other all-in-one lenses, distortion results are confounded. Distortion is ordinarily high for the broadest angle setting (15mm) – practically 1% barrel distortion in the corners, and 0.5% all things considered. This distortion levels out by around 20mm, where the corners then go towards pincushion bending at 24mm. After this central length, there is some meeting, yet distortion never reaches zero at either range.
Buy this lens if:
On the off chance that you are on an excursion and don’t know precisely what you are going to take a general-use lens like this one with you to ensure you have a lot of choices.
With 24 mm effective central length at its wide end and exactly 136 mm at its, Tele end the lens is a perfect sidekick for an assortment of shots from gatherings of individuals to individual portraits, scenes, plants, structures, general travel, and so forth.
The 15-85’s huge favorable position is the more extended focal length range – which augments both more extensive and fundamentally more. The more extended end position is extremely valuable for representations whereas the 85 works vastly improved for tight pictures.
The lens’ aperture reach is not something to be too happy for (not at all like say the EF-S 17-55mm F2.8 IS USM) however is sufficient for general purposes.
Don’t Buy this lens if:
– You need excellent flatness of field
– You cannot tolerate shading or vignetting
– You need precise macro capabilities.
The 15-85 is not a quick lens and has a variable most extreme aperture. 24 mm will be sufficiently wide for all with the exception of dramatic ultra wide-angle shots where you may require a specialty lens.
Also, with solid light sources in the edge, a veritable rainbow of shades is present over the picture, so it may not be the appropriate lens for shooting towards the sun.
With great, if not magnificent results for sharpness, distortion, corner shading, and chromatic aberration, Canon has discharged a brilliant general useful lens. In the event that you were searching for a move up to a unit lens and can’t choose the wide edge and telephoto, this could be an amazing decision.
The fabricated nature of the lens is great and certainly a change over past Canon buyer zoom lenses. Ordinary for Canon lenses including a ring sort USM the AF execution is extremely amazing. The IS (“Image Stabilizer”) works fine inside of its limits.
One More Thing.
The general purpose lens range is a swarmed one, however, the Canon EF-S 15-85mm F3.5-5.6 IS USM Lens emerges from that group by offering top-level picture quality at a for-what-you-get awesome cost. This is not actually a cheap lens, but rather I think it is an awesome quality for what you get.
