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.

A must have!
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.

Shallow Depth of Field
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.

This lens has quickly become my new favorite for p
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.

Awesome Mount
It is pretty helpful to mount any EF lens with my Canon M50 and there is no change in Auto focus and image stabilization which is too good...

Q
Can the lens aperture be controlled with this adapter? I am worried that I won't be able to change aperture values as there don't appear to be any electronics.
A
Hello,although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate while using this adapter. There is no electrical contacts in the adapter ring. Full manual operation, manual focus, manual iris adjustment can be achieved with body manual exposure, aperture priority exposure. 
Q
Is it autofocus or fixed focus ?
A
This is fixed focus. 
Q
The listing doesnt say it will work with a GH5. Will it?
A
I have the Nikon F mount version and it works with the GH5. It's all manual focus, of course. There is no lens data transmitted to the camera. 
Q
Will the 71404 work with a tripod mount?
A
Yes there is a mount . You need to pop out the celestron logo on the focus dial. This would reveal ghe threaded screw adptor 
Q
Does this adapter allow for canon fd lenses to focus to infinity on sony e-mount mirrorless cameras?
A
yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it.
