Top-notch wide-angle zoom lens
I bought this lens because I found I was often wishing I had a bit wider field of view than I could get with my workhorse 24-105 zoom. I'm sure a fixed-focus lens would have offered the absolutely best quality, but I'm so used to the flexibility of a zoom that I prefer the slight loss of quality a zoom is bound to bring.
The choice of F4.0 over the much heavier, more expensive F2.8 17-55 was particularly easy for this lens: at very wide angles I'm not looking for bokeh.
I'm entirely pleased with results so far. I see what many reviewers mean about the slight softness at the corners when the lens is wide open, but the overall quality is pretty superb. I used to imagine the differences between 'L' series lenses and the rest was pretty minimal till I bought my first 'L': now I'll never even consider a lower-quality lens.

Must-have attachments for Dremel and similar drills
I bought this set to tackle a very specific job: enlarging some holes in a piece of anodized aluminium. Most previous mini-drill attachments I have used either break or wear down very fast. The three items I used from this set were very effective. They did the job splendidly and show no signs of wear. I'm very impressed. And, of course, the price is a bargain!

Batteries don't hold their charge; won't charge to 100%
Third-party lithium-ion batteries are always a dodgy item to buy. I decided to try Neewer brand since I have previously been satisfied with their products. But these batteries are not dependable.
Positives: my Canon 5D Mk IV does recognize the batteries and registers them.
Negatives: the two batteries I bought clearly differ in their ability to hold charge. One reduces faster than the other. Even worse, according to the camera, neither battery now reaches 100% charge, even when left on the charger overnight.
