There are reports of some AF confirm chips damaging the EOS AF; has anyone had any such issues?

I can't say that I have. The lens I use this adapter on does not have an Auto-Focus. Having said that the AF on my other lens has been acting a little strange lately.

I have used this product for almost a year. I have yet to experience any problems with it, but that doesn't rule out that there are. I use the adapter on my Canon T3i & Canon C100 to shoot stills and film commercials.

yes but after using it my autofocus stopped working after turning the camera on with regular ef lenses. so i stopped using and got a different one off ebay without the AF confirm chip

Had ours now for almost a year. No problems but share in your concern. It seems very easy to damage since that is the access for the SD card.

I haven't had any problems yet. I use the gps several times a week and haven't noticed a decrease in performance or accuracy. Not sure about about NFC interference

I haven't had any issues. I've had mine since the beginning if August and shot 3 full sets (100+ images each time) with no issues.

Thanks for the tip. Same happened to me one year and ten days in. The silicon trick worked!

One isn't beat up at all because I use a wrap case around it. My mother had a point and shoot with an af error. It just had some sand in it from going to the beach and I fixed it by banging it on the table until the sand came loose. Canon had a recall on the S100 about the af issue. Do a google search for "Canon S100 recall" and you should find out how to make a claim.

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.

Some manufacturer's put the NFC chip in the battery itself. I know Anker is one of the few aftermarket battery producers who does have the NFC chips in the battery as well, but apparently not this one.

Aloha, haven't had any issues with mine either. I can only think of basic things like, checking ID for all your units, try splitting different groups and see if one group works and one doesn't, if you have two flashes test to see if you can use one flash as master instead of the ST E3 and see if that combo works then swap them around to make the others masters that would isolate your ST E3. That's all I got. :-)

I got my d800e and the first thing I noticed when I took it out of the box was the rattle. I held the strap rings and shook the camera and found out it came from the flash. I posted about it in another forum and was told it was normal and indeed it is because it's from the metal support that holds the flash up. No need to worry. Only thing to worry about is the left AF issue and the 10-pin connector going limp on you :).

I've not seen this.... be sure and update your EOS-M to the newest firmware if you haven't.

Hi: I feel your pain from past experience. I've not had this issue, but the swab I'm using fits both my Canon & Leica full frame chips. I don't know how much solution you apply to the swab, but I apply 3 drops on each side of the swab and then swipe once left to right, flip the swab over and swipe right to left. Then I spray (carefully) the chip. Maybe you're not making the swab damp enough, which would leave fibers? The only thing I can suggest is to go to the Sensor Swab web site http://photosol.com and do some trolling on what they suggest for your camera. Email their tech support as well to get their thoughts. Good luck!

I ripped my chip out because my lenses do not need them and when the chip was on my canon t5i refused to work. Info is hard to get on the chips. After ripping the chip out my camera works fine. You only scratch the inside of camera when you forget to use chip. The adapter will not scratch camera body. Good luck

Not sure what "issues" exactly means. But the vendor does give a waranty on the chip. Just contact them.

Sorry to hear that, I don't know anything about that, maybe you have to go through the process once againPerhaps the chip is not sitting squarely in the mount...

I had the same issue and they tried to tell me that it was a result of impact too. Not true. They wanted to charge $100 to tix but finally agreed to fix. I am disappointed and frustrated with the experience. There is a problem that is causing lens error. Beware. Otherwise the camera takes great pix.
