i had the same issue everytime i wld turn it on it wld click so err 99 is broad i removed the lens and the component in the back by the mirror was getting caught i popped it back so now i take pictures no err 99 but half of my picture is black smh

Thank you very much Michael for your informative video. I followed your tips, removed and reinstalled the battery, card, and lens. With out the lens being installed, it worked fine with NO Error99 except once. But after installing the lens the Error99 appeared again.

For 2nd time I turned off the camera and removed the lens & battery then reinstalled them back. Now it works Ok without giving me the Error. What do you suggest if I get the Error99 again & what would be the Problem? APPRECIATE IT

[MichaelTheMentor]

@B4uknowme09 Try it with a different lens! Sounds like this is where the problem is.

good job bro....

Very good exlaination Andrew. However "error 99" when using lens is 95% lens aperture problem. and 5% lens main bd. if camera has lens contact falure , you will see "error 01". Cleaning lens contact won't help much.

[MichaelTheMentor]

@gervin911 Thanks! This lesson was actually the same steps Canon outlined for me when I had the issue, so...its more of a way for people to identify where the error is. And yes, contact issues can cause error 99 as well.

[DanyVargasGT]

Great, it works fine for me, Thanks!

[irulethe70s]

It is the sensor

A resistor failed(popped)

I have famus ERR99 from a week and today I find out it's happened only with EF-S 17-85mm and only between 17-29mm. From 30-85mm still works great so it's a obviously lens problem.

I heard that sending it to Canon costs almost the same as new one. I think I will try to fix it by myself.

There is one DIY site.

If it fail the new one byt not 17-85 this time will have too be bought.

Please cross your fingers. Thanks

i have the same problem with an external flase... what do i do ?

[Iamu4ea]

Thank you so much for this video!! It works great now! 

[Hadassah28]

I have dealt with that issue and a firmware upgrade corrected it absolutely FREE.

[Benjamin5050]

i find i only get it when using adaptors, i think the signal to the lens gets from the body weak and the camera cant read it.. i just pull the Batt and put it back in and it works again just fine, if not then i wipe the pin contacts clean as i find sometimes they oxidise but on the whole i never get a major issue. good to know this thou

[dakipro]

I had 99, and it was battery problem. Battery was "lying" the camera about its capacity and went empty while still showing the full state. Then camera had no idea what the issue was, and reported 99.

[Coccc22]

thanks

[rudiwells]

Same as insightskate, I had this when trying to use the flash on my 40D, it would just hang for a few seconds and give the error. then one day a couple of weeks later it just started working

[InsightSkate]

I just started getting the error 99 yesterday... and it only happens when I use the pop up flash... I really hope I don't have to send it to canon

[Poi159]

Thanks for the tip! Will keep that workflow in mind.

[InsightSkate]

holy crap you read my mind by posting this. got 99 literally yesterday

[cameramanu]

Yes I had it on my 40D so I sent it to Canon and they fixed it. My 7D had no problems.

[N6600]

please help. how can i take shot w/o the len? what mode? how? thanks.

[AETrainingDavid97]

@N6600 Manual mode.

It's a good mode for using adapters to other lenses like the Vivitar 650-1300mm.

[N6600]

@AETrainingDavid97 thank you sir.

[AETrainingDavid97]

@N6600 No problem :)
