How can this item fail completely? No focus possible with any combination of 2 cameras and 3 lenses... Worked perfectly yesterday.

Using an extension tube changes the optics of the lens. One result is the range at which your lens will focus is reduced. When I use the EF 12 II with my 24-105 mm my autofocus still works. However I am closer to the subject than I could normally be (without the extension tube) & still focus this lens. So the extension tube does magnify but it also decreases the focus range.

i was always under the impression that putting the attachment on disables the auto-focus completely. My honest opinion, this is an attachment for tri-pod close up on subject camera use.

No !As I said in my comment about the camera, the lens stopped working ... then, after a couple of tries to turn it off and on again with a full loaded battery, it just stopped to work ... no more screen, nothing, dead !

Yes I received mine a week ago and the lens crashes into the filter; not just in macro but any time the camera struggles to focus. Reading online apparently the lens can protrude a little when focusing causing the crash. I think I got a lemon so the adapter ring is going back.Update: nevermind I'm just a dumbass. I had accidentally assembled it in the wrong order. All is good and focus works fine. Since it is possible to put together backwards it makes me wonder how many of the focus reports are just user error.

Sorry I just saw the incoming email. Let me understand first. Are you saying that there is no way to do an "autof" on your camera with the lens? Try half way press the shutter see if the focus can be achieved.

My Daughter has this Camera and now her auto focus isn't working on it, so she has to manually focus it. I'm wondering if it is the lens or is it the body of the camera. She only has one lens so she hasn't been able to trouble shoot the problem and since she's away at college I'm unable to do anything about it at the moment. Anyone have any ideas?Thanks

I've had mine for two years and it hasn't failed. Never heard anyone mention the AF failing. AF back focusing, or front focus, yes. But depending on what Canon body you're using most the time Micoadjustment enables you to tweak the lens to focus properly.

I truly don't know, that's a shame. Have you tried tricking it by turning it on WITH the lens cover still on, like it's saying, and then removing it to see if the message goes away? Then see if it functions normally after that. Other than that, I have no ideas or suggestions, sorry. I haven't had this problem. I'm sure a local camera shop could help you troubleshoot, possibly even for free if it doesn't require a repair. :)

Hi All, very interested in these postings but still can't get this lens to work with my D70 in M or AF. I too get fEE message displayed and shutter won'r fire, even after locking off at f22 etc. Starting to wonder if its a camera setting or am I missing something?

Send it back immediately- Amazon is great about returns. Mine is as solid as a brick and is the best built lens I own. You will see when you get another one back.!

Honestly, I have not ideas. I'd think there could some small particle may have got into zoom section of lens and prevent the cover shutter from closing. the camera reports the error because of it.I just slide in a piece of thin plastic paper around "trying" to clear things up ,and lightly tap the lens while extending & extracting the lens. somehow, that cleared the problem by luck. but I really don't know how long it will last though.

It just so happens that yesterday I tried the 2.0 on my 7D Mark II with the new 100-400 II lens and it lost its AF function. It works fine with the 1.4 extender, though.

I also had similar issue, solution to this was to replace the broken lens cover, but few days later when I was just checking the lens cover, its broken part came out and my camera started working again properly, only drawback is that I dont have any lens cover more, but still the functioning has not impacted for any reason.

Did not try any action shots. Did not even pass my first test for Auto Focus and what also to expect? I would recommend DSLR for good multiple action shots. Always dependable.

It just doesnt seem like any of my pictures are focused well and that includes ones taken on a tripod with IS turned off of course. I keep reading and trying everything to no avail. I may contact Olympus and see if something is wrong with the camera. I entered a question about my problems in a forum and the responses were so cruel that I wont ever go back to that forum. There is a review that says the E520 pics can be soft... does that mean out of focus too?

Joshua, I can tell you that I have tried several lenses without success - I would try the forums or take the unit to a camera store that specializes in lenses and fit it into the unit to test. I am also searching...
