I can say that the 28-75mm F/2.8 DI III VXD G2 (Model A063) is the best lens not only for pros and advanced amateurs but also families.
Every mom or dad with a camera has had the experience of missing out on capturing those decisive moments from the moment children learn to walk. The Model A063 has the performance to reliably live up to that desire to capture the moment that is right in front of you. The ultra high-speed AF and accuracy has been improved over its predecessor the Model A036, and the enhanced optical performance across the entire zoom range turns those moments into beautiful images.
In a large improvement over the Model A036, the lens also suppresses flare under backlit conditions, which is an essential element of emotional scenes and gives way to unrestricted shooting. At the 28mm wide end, the maximum magnification ratio is 1:2.7. This welcome spec lets you capture the tiny fingers and feet of children in a large size and reliably record moments that depict their growth.
The ability to concentrate is essential for a child’s development. A clear advantage over a fixed-focal length lens is the ability to crop the scene using the zoom, allowing you to capture a child concentrating on play and/or drawing without interrupting. Particularly at the 75mm telephoto end, that extra “5mm” satisfies that desire you have to get one step closer.
At 540g (19 oz), the Model A063 is even lighter than the Model A036, weighing around the same as a 500ml PET bottle. For families, this is perfect for balancing the desire to take photos with what we need to carry for our children. The light weight is also an advantage for photographers, as being able to add another lens for travel, mountain climbing, and other shooting situations gives more flexibility of expression in lens selection.
Performance has been enhanced significantly over the roughly three years since the Model A036 went on sale in 2018, and the 28-75mm F/2.8 DI III VXD G2 (Model A063) also has a more sophisticated look. I think it will usher in a new era of standard lenses for photographers and families alike.
