Canon as of now had a superset of the 17-55mm central length range secured with the Canon EF-S 17-85mm F4-5.6 IS USM Lens. The EF-S 17-85 IS has a higher form quality, picture quality and list of capabilities than the EF-S 18-55 – including Ring USM and 3 stop picture adjustment to the list of capabilities. What the 17-55 IS adds to the 17-85’s list of capabilities is an altered f/2.8 gap and L-Series grade UD (Ultra-Low Dispersion glass) lens components. Obviously, value, size, weight and a decreased central length reach are the drawbacks of the 17-55 contrasted with the 17-85.

Before saying whatever else, we need to concede that in the picture sharpness class, the Canon 17-55 mm ends up being phenomenal.
Inside of the entire center extent, for F4.0 – F5.6 stops, the tried values achieved a 40 lp mm level that is comparable with the some of the best prime lenses. The Canon completely open aperture test results are additionally worth specifying. With the scope of 17.30 mm, tests outcomes achieved a high estimation of 38 lp mm.
In a nutshell, the stop range and centering of the tried Canon gave sharp pictures in the focal point of the casing.
While as yet recalling Canon’s terrible mix-up with the 17-85 IS USM model, we were extremely inquisitive to see the test after effects of the new lens.
We need to genuinely concede we were somewhat frustrated. Indeed, even with a totally open aperture, the chromatic aberration is plainly obvious and achieves a 0.11% level paying little respect to the central length. Luckily, to tackle the issue in 17-30 mm concentrating you should do nothing more than stopping down the lens. This, be that as it may, does not work with a 55 mm where the chromatic aberration never falls underneath 0.1%.
Shading or ”Vignetting”:
Since Canon’s EF-S 17-55 mm is sizable and should project a photo on an APS-C class identifier which is littler than a 35 mm film cut, we were expecting great test results in the vignetting classification.
For this situation, we were extremely frustrated to find that for a 17 mm central length and totally open aperture the light fall off in corners was as high as 40% (- 1.5% the stop esteem). Halting down the lens helps a bit however it doesn’t tackle the issue. For F4.0 the vignetting is 24%, and just for F11 we come to the most part respected the unnoticeable level of 10%.
Since Canon’s 17-55 IS USM has a little central reach it deals with geometrical deformations. With a most extreme wide angle, we watched a recognizable however not too big barrel distortion with a level of – 2.47%.
The distortions lower to the point of 24 mm where they achieve least and nearly to the zero level. At that point, they begin expanding again and, at 30 mm, the distortion gets to be the pincushion and achieves an estimation of 1.06%. It keeps gradually expanding and for a 55 mm, the outcomes are 1.38%.
Buy this lens if:
With an altered fast F2.8 aperture (that means the most extensive gap opening is F2.8 through the whole central length range – F22 is the tightest setting), introduction settings don’t change when zooming on a subject. It is sufficiently quick to stop activity in numerous indoor venues (where higher ISO settings are ordinarily required – fast action indoor sports might require F2 or more extensive).
In case you’re genuinely into low light work or portraiture, the Canon EF-S 17-55mm will charm you. The more you see what it’s optics are able to do, the more you end up taking shots under conditions you’d beforehand leave.
Don’t Buy this lens if:
It’s certainly not for a novice picture taker, for travel, outside games or moving articles photography, who should be going to be discouraged by the high cost and the size. It’s additionally not for an advanced picture taker who would be discouraged by the lens’ imperfections and will purchase something less costly, sturdier, better and altogether tried, similar to the Canon 17-40 f/4L.
All Canon fans have as of now been utilizing the full casing Canons 1Ds Mark II or 5D. The EF-S 17-55 can’t contend with them, yet regardless of the fact that it did, clients would pick the less costly L-grade lens Canon 24-105 F4L IS USM or the main somewhat more costly Canon 24-70 mm F2.8L, for landscape, bright light and also portraits.
With the presentation of the 17-55 IS, Canon shows its dedication to the EF-S line of lenses. With the immense base of Canon EF-S Digital SLR clients, the 17-55 IS, with its elements, specs and picture quality, will locate a home in numerous expert picture takers’ pack.
One More Thing.
