Verdict

The Canon EF 24-105mm f/3.5-5.6 STM IS has a couple of the "right ingredients" for being a potentially good performer - it doesn't really have an ambitious zoom range, the max. aperture is very moderate and despite all this, it is a comparatively big lens resulting in only moderate optical constraints. So how's the end result ? Pretty good ... although not flawless. Technically the lens is surprisingly sharp. The image center is especially impressive at mainstream aperture settings. The borders/corners are also decent. However, the field curvature can spoil the corner results at the wide end of the range and near infinity focus. Distortions are visible at the extreme ends of the zoom range. Lateral CA are generally moderate except in the corners at 24mm. The 24mm setting is also a bit of a weak spot with respect to vignetting at max. aperture. The EF 24-105mm f/3.5-5.6 STM IS is obviously a slow lens and as such you shouldn't expect wonders regarding its bokeh potential but the technical quality is comparable to other standard zoom lenses.

The build quality is good and in line with Canon's recently released consumer grade lenses. If you are used to L-grade qualities, the amount of plastic will be obvious but everything is decently assembled really. However, zoom creeping may be a little annoying but this isn't unheard of among other full format standard zoom lenses. A transport lock can help during storage at least. Canon seems to be willing to push its fairly new STM AF technology into the full format market now. We'd say that this is a good thing actually. The AF speed is slightly reduced but noiseless (even more so than USM) and the stepping motor is superior for auto-focusing in Live View mode. Some users may have to get used to the "fly-by-wire" manual focusing but Canon's implementation is better than most here. It's quite interesting to note that the image stabilizer (IS) is slightly more efficient than on the higher priced Canon EF 24-105mm f/4 USM L IS.

So how's the Canon EF 24-105mm f/3.5-5.6 STM IS compared to the rest of the gang then ? The problem is that all of the 24-105mm lenses have issues here and there so the Canon lens is in "good" company. Price-wise it is ahead (well, cheaper) but then it's also slower. Thus right choice in the standard zoom lens class remains a difficult one unfortunately ...
