The auto-focus is fast! Fantastic for sports photography. Can't go wrong this lens!

Using this adapter on my Canon M50m2. Auto focus and all settings work just as they should. For $40 this is a very fairly priced piece of kit and is used every day.

Works great. It would be good to put somewhere how to focus using it and the lens. It only auto focus' with certain camera and lens combinations and with some there is a trick to it, otherwise you have to manually focus. But it is a great addition to my lens collection.

Even if this doubler doesn't allow auto-focus, it's great for just about every lens when you find yourself needing more telephoto capability. The 2 f-stops lost are handled well with a monopod. Top rate glass by Canon. Worth every penny.

Something I wish I'd understood when I bought this -- the camera's lens can only focus to about two feet away -- so let's say you want to talk to someone from slightly further away? You're out of luck. Within two feet, it's a great webcam with decent auto-adjustment, though it's auto-exposure is sometimes kind of wack.

A absolutely ADORE this lens. I am an amateur photographer and this was my first purchase outside the kit lens that came with my Canon. I was impressed that I could get a lens of this quality at such a reasonable price and it was available on Prime so it arrived in two days.The lens is static, which does take some getting used to. The image quality from this lens is crisp and clear. I shoot with it on very low aperture and my images all have turned out extremely sharp. The auto-focus is a little more sensitive than a regular lens, which also takes some getting used to in the beginning. Because this lens is static, the manual focus is also right near where you put your hand to hold the lens steady, so be sure to watch out for that or you might accidentally override the auto focus by slightly turning the manual focus ring.This lens has quickly become my new favorite for portraiture photography, especially with newborns.This review was posted voluntarily without promotions, coupons or discounts.

This adapter seems to be well made. I haven’t tried the auto focus because I wanted it as an adapter for a manual focus lens. For that purpose it is very good.

This is a great auto focus lens mount adapter. It seems to work flawlessly the few times that I have used it. I would recommend this product.
