Canon announced the development of six interchangeable lenses for RF mounts at the launch of the full-size mirrorless “EOS RP” in February 2019, and announced that all will be released within 2019. If the "RF85mm F1.2 L USM DS" scheduled to be released at the end of December appears on schedule, all six lenses will be released within the year as predicted. From these six interchangeable lenses, I would like to check the ability of the standard large-diameter standard zoom lens “RF24-70mm F2.8 L IS USM” again.
Although it is 100g heavier than the EF mount version, the depiction performance is exceptional
The Canon RF mount used in the EOS R series is surprisingly available in three types of standard zoom lenses. “ RF24-105mm F4 L IS USM '' familiar as a kit lens, “ RF28-70mm F2 L USM '' boasting unprecedented open F2 optical performance, and “ RF24-70mm F2.8 L IS '' that appeared this time USM ”. In particular, the RF24-70mm F2.8 L is a spec that can be said to be a “standard” with 24-70mm and open F2.8 through, so there may have been many users waiting.
The lens design has changed, and the optical design has been renewed from the “EF24-70mm F2.8L II USM” for SLR cameras. I think that the lens will be lighter because it is mirrorless, but the RF24-70mm F2.8 L weighs about 900g, which is about 100g more than the EF mount version of about 805g. However, since the camera itself is light [this time using EOS R], it actually feels lighter than a full-size SLR camera and a lens with the same spec. The open F2 through RF28-70mm F2 L weighs about 1430g and the filter diameter is 95mm, which isn't easy to carry around, but I feel that this lens can be used regularly.
An improvement over the EF mount version is that it is finally equipped with an in-lens image stabilization mechanism. Compared to single-lens reflex cameras, where a large mirror is driven when the shutter is released, mirrorless features less impact and less blurring. Nonetheless, with the high-quality EOS R / RP, even slight blurring can lead to a reduction in resolution. The fact that it is fully equipped with an image stabilization mechanism can be greatly appreciated. The effect of camera shake correction is also complaining that the shutter speed is 5 steps. The shortest shooting distance, which was 38cm in the EF mount version, has also been shortened to about 21cm.
The essential performance of the image is incredible, and you can revolve even if you look through the viewfinder and look at the images you have taken. The in-focus area demonstrates high resolution from the full aperture. From there, I gently blurd back and forth, and I felt that the three-dimensional appearance and texture reproduction were appropriate for the latest lens. I tried the harsh conditions of backlighting, but the backlighting resistance is quite high.
For EOS R / RP users and those who are planning to purchase, it may be annoying which one should buy RF24-105mm F4 L. The answer varies depending on the shooting genre, the equipment on hand, the budget, etc., but considering that the aperture is one step brighter and the shortest shooting distance is short in terms of expression width [RF24-105mm F4 L is about 45cm, RF24-70mm [F2.8 L is about 21cm]
