So if you don't mind the adapter and have (or plan to get) a longer lens anyways, I think the 24-70 f2.8 mkii would be a good choice. Tmjc's gear list: Canon EOS R8 Canon EF 100mm f/2.8 Macro USM Canon EF 24-105mm f/4L IS USM Canon 70-300 F4-5.6 IS II Tamron 17-35mm F2.8-4 +2 more. L’autofocus. Le système AF du 24-105 s’en sort très bien, mais il a toujours un peu de pompage alors que le 24-70 n’hésite jamais. Si vous voulez un objectif plus haut de gamme, vous allez trouver votre compte avec le 24-70mm f2.8 : meilleur piqué, plus de contraste et moins de défauts optiques. En revanche, le RF 24-105 mm f4 est Slightly off topic, but I've found the RF 28-70 and RF 50 when both shot at f/2 near MFD have identical bokeh character. When choosing between the 24-70 vs 28-70, I also try to encourage people to consider 15-35 / 50 / 70-200 and forget the standard zoom altogether. Once you have the 15-35 and 70-200, you really only are missing 40-65. So if you are satisfied with the performance of that lens, you should be pleased with the new RF 24-105 F2.8L. Preorder the Canon RF 24-105mm f/2.8L IS USM Z. B&H Photo (US): Canon RF 24-105mm f/2.8L IS USM Z $2999; Adorama (US) : Canon RF 24-105mm f/2.8L IS USM Z $2999; Midwest Photo (US): Canon RF 24-105mm f/2.8L IS USM Z $2999 Canon makes an 18-135mm zoom which is a good "walk around" lens. It's not as good as the 24-105 and not nearly as good as the 24-70 because that lens has a "variable focal ratio" and doesn't collect as much light. The 24-70 and 24-105 are both "L" series lenses -- Canon's top-end glass. But one of the rules for qualifying as an "L" series lens 但给写简单的建议,如果是新手建议 24-105 ,先用用再说,更多的 变焦 ,缺失的光圈可以通过长焦弥补。. 24-70 变焦比不大,新手会觉得怎么拍不出彩,千万别迷信 大三元 ,24-70其实俗称干活头, 标变 很考构图和布光的,而24-105买套机或买拆机头,不合适再出 8DgJ4. I've been reading some of the previous suggestions, including re-reading my own, and I think we have gotten somewhat off-base. First, you state you are brand new to photography and want to do astrophotography, landscapes, portraits and close-up photography. You also plan to hike with your gear. Less DoF at F2.8 vs F4.0 but this is obvious. The lens will retail at over twice the price of the F4 lens. And I expect the optics to be far far better also. It will also be twice the size and weight too. You dont buy an F2.8 zoom just to take slightly better low light photos. 24-70/4 at B&H = $1,198. $1,198 x 2 = $2,396. 24-70/2.8 at B&H L’autofocus. Le système AF du 24-105 s’en sort très bien, mais il a toujours un peu de pompage alors que le 24-70 n’hésite jamais. Si vous voulez un objectif plus haut de gamme, vous allez trouver votre compte avec le 24-70mm f2.8 : meilleur piqué, plus de contraste et moins de défauts optiques. En revanche, le RF 24-105 mm f4 est I have the EF 17-40 (pretty decent, may even wanna just pick up a 16-35mm used at some point to get better sharpness) and 24-105 (not my favorite, and the lens creeps down when carrying). I may just give all these a try on the R5 for a few months and either bite the bullet on 24-70 or settle for the RF 24-105. 1. Thanks for your elaborate answer. These are the lenses I currently have: Canon EF-S 18-135mm f/4-5.6 IS II (kit lens) Canon EF-S 24mm f/2.8 STM Canon EF 50mm f/1.8 STM Canon EF 75-300mm f/4-5.6 IS II USM Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD I am using a Canon 750D (Rebel T6i), so I am looking forward to upgrading to fullframe.
