1、F2.8的 大光圈 ，即使是在室内拍摄使用，也不用担心光线的问题. 2、 24-70mm焦段 从广角到长焦，可以远近自如的取景构图拍摄。. 3、 超声波马达 ，拍照安静且对焦速度快，. 4、有5级的 光学防抖 ，手持拍摄更轻松. 不足： 24-70mm 的变焦镜头属于各个方面都很 The Comparison: Canon vs Tamron. Canon’s EF 24-70 f/2.8L II USM has been hailed as the sharpest lens of its type, but it has no image-stabilization, and it carries a hefty price tag at $2049. On the other hand, Tamron’s new 24-70 f/2.8 VC USD does have image stabilization, but the company’s optics only occasionally match the standards 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. The new RF 24-70 f/2.8L IS lens, as the last two let­ters of the mod­el name reveal, has a built-in opti­cal image sta­bi­liz­er, as does the RF 24-105 f/4L IS I test­ed here. On the oth­er hand, the EF ver­sion of the 24-70 f/2.8L II that I test­ed here does not fea­ture a built-in opti­cal image sta­bi­liz­er. You can still get better high ISO with the 24-105mm then the 24-70mm f2.8 if you use DXO PhotoLab 4 Deep Prime or DXO PureRaw Deep Prime. If you used the 24-70mm f2.8 ok then you would get better high ISO. But if you use DXO Deep Prime its like with the 24-105mm f4 you will get two extra stops of high ISO. Walk around 24-105 rf is way better than the one it replaces and demonstrably better. I also have the 35mm rf which is the new nifty fifty, light and efficient, macros or whatever. 50mm 1.2 rf, my 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. My first three lenses would be the 24-105mm f/4 for general purposes, RF 85 f/1.2 for studio and portraits and the RF 15-35 f/2.8 for landscape and urban work. 2 0 .
