The Canon RF 28-70mm f/2 L USM is a large and very heavy lens, considering the rather modest focal range that it covers, weighing in at a whopping 1430g and measuring 14cm in length, extending further to 16cm when the lens is set to 70mm. It's best to think of this lens as four high-quality prime lenses in one, rather than just as a standard 70mm at the long end isn't too long, so the rough rule of using 1/focal-length as a minimum shutter should give you lots of options for hand-held shots (e.g. being able to use down to around 1/80s). The 5D IV has very good ISO performance, so if you can definitely increase the ISO should you need faster shutter speeds in lower-light scenarios. 佳能EF 24-70mm f/2.8L II USM 镜头概况介绍：. 对于大多数初学者来说，标准变焦镜头是个很不错的选择，焦段涵盖了广角到中焦，风景人文通吃非常实用，能准确再现你眼中的事物。. 如果你经常在室内拍摄或者棚拍的话，这几乎是一只必备镜头。. 2002年佳能发布的EF Photokina 2002: Canon has introduced a new wider replacement for the popular EF 28 - 70 F2.8 L USM lens.
