佳能申请的3支中长定焦头 防抖专利,这是要把防抖进行到底的节奏啊!Patents with three popular telephoto lenses with the addition of image stabilization have shown up. It’s long been expected that we’d see IS added to Canons already highly regarded 135 f/2 and adding stabilization to the 85 and 100 would follow with Canons current practice of sticking IS on all their mid-range glass.
