<p>LensRentals.com has discovered issues with the sensors on the brand new Canon EOS Rebel T6s & EOS Rebel T6i. Out of 20 cameras they received the exhibited the following issue.</p>
<blockquote><p>Every once in a while we notice something, because of the large quantities of cameras and lenses we buy, that we think people should be aware of. This particular issue won’t affect our renters; we’ve sent the affected cameras back. It may not affect very many people at all, since this is from a relatively small sample size. But I still think it worth mentioning.</p>
<p>The bottom line is that 4 of the <a href="http://www.lensrentals.com/rent/canon/cameras/canon-eos-t6s">Canon T6s</a> and 2 of the <a href="http://www.lensrentals.com/rent/canon/cameras/canon-eos-t6i">T6i</a> cameras we received had to be sent back because of a defect in the sensor stack (the layers of filter glass over the sensor). This is out about 10 copies of each; the others were absolutely perfect.</p></blockquote>

Re: Possible Issue With T6s & T6i Sensors?

Yikes! I'm especially glad now that I decided to hold off on upgrading to an EOS M3 (same sensor?)- even if this only affects a small number of cameras I'd rather not take the chance of getting stuck with a grey-market camera that has a bad sensor.

Really? That is some pretty frightening QA (or lack there of) right there. I'd think some basic tests would be if the camera can take clean pictures. I know I'd be pretty disappointed if I ordered a camera and this was the case.

Yes, I especially want to hear from all those here who offered their analytics on Nikon's D600 oil splatter on the sensor issue and how they would compare this incident. ;)

Yes sir. This seems to be affecting only a few cameras.

Re: Possible Issue With T6s & T6i Sensors?

My wife's new T6s Mothers-Day-Gift arrived yesterday, just 10-days before we head-out on vacation. Then I read this...

My initial panic was not at pretty sight... Words were said that would make a longshoreman blush...

But after scrutinizing the sensor in every way possible, I don't believe that her new T6s is one of those afflicted with the pox. I'm certainly going to keep my eye on it for quite a while though, Roger's pictures of the bad sensor are pretty ugly & alarming...

30% is not "only a few".

I can't imagine Canon issuing a recall. It will probably be a small notice somewhere saying if you receive a defective one they will fix it if you send it in. Most of the consumers of this camera won't even notice it, the problem that is and more than likely any notice. It will quietly get fixed in the background.

Indeed - let's rather discuss q&a issues if they're from Sonikon or 3rd party manufacturers like Sigma :->

As the issue was found by Lensrentals, it might - just might - be that Canon has a special supply pipeline for companies like these, giving early access to volume numbers of new products, but bypassing some q&a steps that are in place for vanilla customers.

I guess I was wrong. This is the calamity of the century. We should all whine and curse and jump up and down waving our hands wildly.
We should discuss this every hour, post on every social media and photography forums till the entire population starts mistrusting Canon. After all Canon has never done anything right for us. We should be as negative as possible in our lives towards Canon.

I was under the impression that Canon has given millions of perfectly working cameras and if some malfunctioned, we should not make a big deal of it.

Re: Possible Issue With T6s & T6i Sensors?

There are many things this could be, dust at point of assembly, adhesive / bonding issues, fungus spores prior to assembly etc. but the key is how Canon respond and the LensRental guys stated Canon acted promptly and didnt question their findings.
ALL manufacturers have manufacturing issues from time to time if we didnt notice we dont live in a perfect world, its the responce and action taken that matters we should not live in glass houses.

+1, let's discuss the other maker's issues, not the Canon ones. After all, Canon has no issues, right ? This LensRentals guy must be a troll, working for Sonikon or DxO. Theses are not defective cameras, they are limited editions, that will sell for millions at Sotheby's in a few year.

All fun aside, Canon, like every brand can make mistakes, question is, how will they deal with it ? Problem with the Nikon D600 is not the dust issue, but the pathetic way Nikon dealt (or not) with it. I am sure Canon will solve the issue, hopefully they have learned from their own mistakes with the 1D3 AF communication disaster.

In case this is only some kind of early-series accident, they should be more careful before sending batches of cameras to companies like LensRentals, who are among the best suited people to find flaws, and who's word has more value than a vague internet rumour.

As for the "silent" recall, I do not find it very fair. Let's take the 7D2 for instance, if there is actually a flaw in some of the camera's AF system or mirror box or whatever that is, it would be more honest IMO to issue an official statement allowing all owners to have their camera checked for free. Some people, especially in the entry level market of the t6i/750D are likely to never remove the kit lens, and even if they would, never to realize their camera has a flaw that should be covered by the warranty. So only the people who read forums, or have enough technical knowledge to see something is wrong will have their camera fixed, while a bunch of other will be left over with a defective toy.

That, of course, applies to every company, when a manufacturing problem happens (in case someone would think I am employed by the evil company that's behind every other brand than Canon). ;)

It seems pretty clear that Canon is quite willing to issue service notices (recalls), from the flagship 1D X mirror box to the 5DIII light leak (which was pretty unlikely to actually affect anyone's images), to the entry level Rebel rubber grip discoloration.

Re: Possible Issue With T6s & T6i Sensor?

if it is a problem with the adhesive used to sandwich the glass in the sensor together then maybe the affected sensors are delaminating over time. i don't know how much time passes between production/inspection and shipping? i am not trying to look for excuses but its hard to believe that a obvious defect on the sensor such as this could pass any kind of qc inspection.
