Evaluation of the performance of the Tamron 17-50mm f2.8vc lens

pu1. It's a little disappointing compared to the Canon EF-S 17-55mm F2.8 IS USM, which is called the Blessing Lens, but it's very good if it's the same wide angle and has the same f value. It can be as bright as a blessing lens

OK

pu2. Looking at the zoom lens, it's right that it's bright. There are about four bundled lenses. But in absolute terms, single lenses are 12, 14, and 18, so it's a shame compared to single lenses. The purpose of zoom lenses is to use zoom quickly and comfortably, so if you want bright lenses, single lenses are good
