[Expired]Canon Refurbished RF70-200mm F4 L IS USM

: Sooner or later means how soon? Just one stop more than 2.8. The RF 135mm f/1.8 is the real deal. 迟早是多早，2.8多一档而已，rf 135 f1.8才够用

: Seeing many veteran photographers switching back. f/2.8 will eventually upgrade to f/4. Neck can't handle the weight anymore, and don't even like using a tripod. Lighter is better—it's all about landscapes and lotus shots anyway, those extra stops don't matter 看到好多反过来的老法师，2.8早晚上4。颈椎不行啦，dp也不爱用，能减重就减重，反正也是风光荷花，不差那几档光圈

: Where can I buy it? Seriously looking to get one. 在哪能买到，诚心收

回复 @奚仲2 : He's saying he couldn't afford to pay even a little more, haha. 他是说多一分也买不起哈哈哈

: Are you the Wall Street Bull come to life or something?! $500 is what it's actually worth; you're not even paying for it! Even with f2.8, F0.8 you still can't produce a masterpiece! 你是华尔街铜牛成精了？！还500刀才值，咋不贴钱给你呢！ f2.8，F0.8你也拍不出大作！

: True, it's first come first served. Bought two, planning to resell one later. 确实手慢无、买了2个 准备2手出一个

回复 @看我的小马尾 : If you can tolerate the weight, you might as well consider there's zero difference. 你如果能忍受重量的话，可以认为完全没有区别

: >But 2.8 is really big. I just can't bring myself to accept it.</c17370075>If you buy the f4, you'll eventually want to move up to 2.8 sooner or later. ef2.8和rf2.8有什么区别吗
