Problem solved: Batteries in Canon 7D mark ii going dead over night
Nov 11, 2014 09:09:47 #
Well........... I think I found the problem, but now I have another one. When I received the Mark ii last week I had just purchased a Tamron 24-70 because I needed a 2.8 over that range. I loved the photos I was getting with the Tamron, so I left it on the new camera as the 'every day' lens.
In searching for a solution to the battery drain, I ran across a reference somewhere that mentioned the possibility of a lens shorting out and draining a camera battery. So I removed the Tamron and put on a Canon 70-200 instead. This morning there was NO measurable drop off in battery power.
Now I have another problem. Though the Tamron performs beautifully with regard to photo quality, will the use of it cause any damage to the camera?
I have an email in to Tamron to see about a possible repair but as yet I have no response.
UPDATE: I just found a discussion board where others have had a similar problem with this lens. Bummer.
I can't post the link because the thread will be moved. But if you google the terms 'Tamron 24-70 battery drain' it will take you to the site.

I have also read that leaving the GPS turned on will also drain the battery even with the camera turned off....

I had the GPS turned off. The only difference in whether the battery drained over night was the presence of the Tamron on the camera.

Thanks Bill. That's EXACTLY what's happening. I do like the lens and hope that Tamron can offer a fix, but if not I will probably keep it, but will only have it on camera when I'm doing something where that particular focal length is needed.

Depending on who you bought it from, they just might exchange it. If you only got it last week.

I find that most people cut costs in the worst way, for example buying a top-of-the line camera body and putting a 2nd-rate lens on it. Doing the opposite: 1st rate lens and lesser cost body to me makes much more sense.

Send him a good lens, I'm sure you'll make the top of his buddy list. I love how some people love to spend other peoples money.
I think they call it starting somewhere.
And it isn't a cheap lens, thats for sure. Just because it doesn't have a white barrel.

This thread has nothing to do with whether a lens is top of the line or middle of the pack. It's about a power drain problem that others may run into someday. Until this issue, I had no idea that the lens could cause a problem like this with the camera.
As for being a 2nd-rate lens, that depends on who you ask. It does everything I presently need it to do, and it has IS, while the Canon equivalent does not. It also costs about a thousand dollars less. It's the only non-Canon lens I own but I really like the quality of its images.

thank you gym as i am about to purchase this second rate lens and had not read about this problem , i dont worry about the name stamped on a lens just how it performs and all the reviews ii have read say that it out performs its more expensive rivals in a lot of areas and having IS when your getting old it seals it for me , i will still buy it but now will know to keep an eye out for this problem so thanks again
p.s in australia you can purchase age old australian brand names only to find they are made in china anyway sure the USA is the same, they just cost more

Gawler, I'm not saying you shouldn't get a Tammy, I'm sure they are decent and cost 1/2 as much as the Canon counterpart.
But rarely will anything function on a Canon as well as a Canon. Canon does spend tens of thousands on R&D to be sure that the system works together somewhat flawlessly. Do keep in mind that Canon makes a variety of the same lens as well as there are refurbs and used lenses. Also consider how much resale a Canon lens holds into the future. Just saying! ;-)

Thanks Gawler. I hope that you really enjoy your new lens. Obviously I'm a big fan of Canon lenses, but let's face it - L glass is incredibly expensive. If I had a choice - all things being equal - between the Tamron and a Canon, then I'd take the Canon. But the difference is minimal - even if you're a MAJOR pixel peeper, and for money, the Tamron is a great deal. IF you have a problem with battery drain, I see on line that Tamron will fix that for you.
All the best to you

That sounds pretty definite. I'd send it to Tamron, since it's under warranty. Let us know how this turns out.

Hi Gym
I have the same lens and same problem with the battery as well. It lasted me 700photos at the most where as the 7D I get 3300photos out of the battery. In saying that.... it did not matter what lens I used.... mostly my canon L 100_400 and still the same result.
My big problem with the tameron 24_70 was that after a few shots the camera came up with error and would not work.
Lucky the place I bought if from took it back and got a brand new one in for me which I pick up tomorrow. Let's hope no more hassles as I can not afford to buy the same canon lens. And
D I use my Tameron as a professional pg
Hotographer all the time.

And yet another reason why not stay with Canon and it's own products? That's why I don't purchase 3rd party manufacturer's products QC is not very good some of the time or more time than not?
