Technical Support / Re: 7D mark II battery drain
« on: Today at 12:18:21 PM »
Hi VinniWongo.
Nice bit of detective work!
I think since the introduction of the transmissive LCD screen in the viewfinder there has always been some power to the camera when off, proof, look through the viewfinder with the power off then drop the battery out and watch the screen dim! Certainly is like this on my 7D.
I don't know why they keep it powered, does it take too long to start from cold, wouldn't be able to quote start time less than 0.2 seconds (or whatever it actually is).
To me, and others looking at GPS, off really should mean OFF.

Cheers, Graham.

Hi all, thanks for the replies so far. I should have stated from the beginning that gps is off, canon original battery, no grips.

I have trawled quite a few forums on battery drain when off and various models seem to appear and looks like it's a possible firmware, hardware combo issue. I stumbled across one guy that videoed his display flickering with a Tamron tele-converter on and also stated that it drained his battery when off. Logic dictates that when a camera is off it should mean no power to anywhere in it's body. However, I currently have a Tamron 24-70mm f/2.8 on the 7D mark II. This lens normally resides on my 5D mark II without any battery drain issues. Last night I put it back on the 5D and stuck a canon 100mm macro on the 7D. Checked the battery % and 11 hours later it is still the same %.

Obviously this takes some time to do these checks and I would want a more conclusive time period for each test, but I will go through all my lenses attached to the 7D to see if it is one model or make that is causing this. None of these lenses cause a battery drain issue on the 5D.

Lenses are Tamron 24-70 f/2.8 VC, Tamron 150-600 f/5-6.3 VC, Canon EF100mm Macro, Canon 70-300 f/4.5-5.6L IS

As I find more results on this I will update, but it will take time.

Most of the models maintain some power during off.  When you open the card door and/or replace cards the camera does a recheck when the door is closed.  This is on all of the models not just 7d2.  If you want GPS on but don't require instant updating, you can set the polling time for very long...like 30 minutes or 1 hour.  That will also reduce the battery drain.  Most of my cameras I've used will also do a read or reset when a lens is changed when powered off.  So off does not mean off unless you remove the battery.

Canon General / Re: Does Canon really deserve this?

To me it doesn't really matter that others are innovating faster than Canon in some areas.  So far I have been largely disappointed with Nikon and Sony as a system.  The envelope is pushed so far that their equipment is not very reliable and certainly not very durable.

The reason I chose Canon was I needed a system that would stand up to challenges, including environmental, and work when I needed it to.  Both Nikon and Sony have fallen short on that with me.  Regardless of Canon's "lack of innovation" in some areas...and I say some areas because there are plenty of areas for which they are ahead in innovation, AF technology being one of them...Canon has continued to delivery exceptional quality for what I need it for.

At this point and anywhere in the foreseeable future, I do not see myself switching systems even if I had the $$$ to just start over.

Just got back from a road trip.....shot 404 pictures over 11 days (mostly in the rain) and the change on the battery is down to about a quarter... Gps is off. Not quite the battery life of the 60D, but certainly much better than the OP.

There was a lot of playing with the menus and a lot of looking at pictures on the screen, so that probably explains some of the loss of battery power.....

Yes I'm finding there is a lot of new camera syndrome where the user is chimping more than shooting.  Though no doubt the 7DII is a power hog.  I knew that going in so I ordered with a grip and spare battery.

EOS Bodies / Re: Focus problems with the Canon 7DII?
« on: November 22, 2014, 04:31:42 PM »
So I had my first real run today with my Canon 7D mark ii and sadly, I have a lemon.

80%+ of my images are showing a focus point on Canon's ZoomBrowser, that were nowhere near where the camera confirmed during the shot being taken.

I'll be asking for a straight swap out, can't keep this body :(

Here's the best of an unsharp bunch

Focuspoints in zoom browser or DPP are not accurate.  They only give you a general idea of which point was active and where.  I wouldnt consider the camera a lemon because of a software issue.  More likely you need to micro focus adjust your camera to your lens.

Can I add lenses my camera doesn't recognize?

Not sure I understand your question.  Are you asking about AFMA on a 3rd party lens?

So far been really pleased with the body till I found out that it drains the battery flat in about 4 days while turned off.

You double-checked gps is off? Otherwise "off" mean (nearly) no battery drain with such an expensive product, and I only expect cheaper companies like Yongnuo to kill your batteries if you don't remove them physically.

I need to rig up a test on how much these cameras drain batteries with different features turned on and off.  SHould be "fairly" easy to measure the current draw from the battery in different situations including power off.

In the OPs case I think there is something wrong with his rig.  Even with GPS on my battery is still 90%+ after 3 days.

... I fabricated a flat target from 5mm thick yellow craft foam and narrow black masking tape so I had a high contrast target.

Apparently I built a focus target that cameras can't focus on. Will contact USAF to see if they want to use it in their stealth technology.

Rod, would you be willing to post a picture of your DIY 'stealth target'?  Thanks!

I actually used the target in the basement this evening. I used regular electrical tape to add thicker angled lines. No apparent problems focusing from about 24 feet. I didn't take any pictures. I just set it up to try the dot tune method for adjusting my lenses. The tamron ended up at -3 on the wide end and +2 on the long end (At least at 24 feet). My 70-300L came in at +2 on both ends. If weather permits I will test things out tomorrow. Also try to remember to take a picture of the target.

Rod

When you are checking the accuracy of dot tune (which for me is not 100%) take some shots of a sheet of newspaper on a wall and see how the sharpness is on fine print.  You can really only trust what you can see when a shot is taken, not what the electronics are reporting.

EOS Bodies / Re: 7D Mark II Amazing Custom Settings
« on: November 22, 2014, 09:24:50 AM »
Every day I am discovering something new with the 7D2..well at least new to me so thought I would start a thread on custom settings that you swear by and why you like them.

The first I would like to share is the re-assignment of one of the back buttons (I used the AE lock button) to assign a recall of a custom setting.  Here you can register any number of settings to instantly load at the push of a button.  So if that's not enough, you can also assign an AF mode.  For this button I unchecked all of the options except for AF area selection mode.  I assign this to spot focus.

Now when I am in zone AF or 65 point or any other mode tracking a bird in the open and need to suddenly stick pick my shot I can just press the AE (*) button and I get an instant spot to focus on.

I am also playing around with the reverse.  It gets tricky when you need to manually move the spot :)  However I am finding this new feature pretty useful.

Please share what you have found.

Could you please tell me how to set this as I am scratching my head trying to understand the manual!

I want to make one of the buttons instantly go to spot-AF (for when I spot a bird behind branches and you need the small spot-AF). The manual goes on about registering an AF spot and pressing various buttons together but I can't make it work, so I would appreciate an idiots-guide to making this work

Thanks,

Ashley

There is a custom setting for those buttons now that looks like a camera with arrows coming in and out.  From there you check or uncheck which function or combination of functions you want to assign to the button.  Check just the AF mode setting then press info to select the AF mode to assign.

This is a new capability for the 7D series.  We dont have this on the 5DIII and wish we did.

So far been really pleased with the body till I found out that it drains the battery flat in about 4 days while turned off. This is with the new battery that has been charged twice. I have just put in a known good battery from my 5D mark II to see if it is doing it with that. Should know by the end of today if it is. All my previous canon bodies (30D, 7D, 1Dmkiv) have never done this.

Has anyone else had any similar issues?

Yes, a friend has the same reported.
Full battery discharged (20% in only 1 Day) although the camera was off (GPS was off too).
I replaced the battery in my MKII well over a week ago and have 92% charge right now.  Unless the gps is "disabled" in the menu it continuously draws current and can drain a fully charged battery is less than a week.  Today I will be shooting pictures at my great-granddaughter's birthday and since I might shoot some pictures between here and there (four hour drive) I will activate the gps.  I'll let everyone know how much the battery drains today (average couple hundred pictures at these parties). 

Mine does not have this problem.  With GPS off, off is off and battery was still full after 3 days.  It is power hungry when on and so I also bought a battery grip and extra battery for it so i can get through the day of shooting.

Decided I'm keeping the 7D2 so I unwrapped the new LP-E6n battery. At first my Watson Duo charger refused to recognize it but after charging for a bit on the LC-E6? I was able to get it going on the Watson. Anyway, man that thing is slow taking a charge. My canon LP-E6 has gone from 45-95% in the same amount of time as the LP-E6n has gone from 45-65%. Hope that improves with recharges.

Let us know how that goes.  I think it may also be the same issue as when the batt drains.  The charger needs to learn the charge rate after several cycles.  The new batts are higher capacity but not that much higher.

Hi,
another flash problem I have, may the third party problem too.
I use the YongNuo YN-622C ETTL radio triggers on my 7D before and after getting the 7D II they didn't work :(
Nearly all exposures where full flash exposures.
If I set the flash control to manual it worked, but ETTL, even with a Canon 430EX II flash on the YN-622C device didn't work.
I would say Canon changed the wireless flash control interface a little bit, so third party flashes could have a problem.
In my test the pre flash for ETTL was too bright, so the camera will send a full flash needed command too the flashes and the picture is overexposed. With the use of the internal flash as wireless master the pre flash isn't that bright.
It's not a Canon problem, but I think it's good to know.

In my thread http://www.dpreview.com/forums/thread/3747630#forum-post-54671707 a user say that the Pixel King ETTL flash devices have the problem too, but this devices have a update function so they may be work later.

Bye

Markus

Curious if these 3rd party flashes work ok when they are attached directly to the camera or is it only when the are used as slaves?

Also if the lens works fine with other bodies then it's not likely the lens. 
...
It wouldnt be intermittent one one body and not on another.  Therefore I suspect it may be contct related or something with that camera body.
7DII is a new body. Dirty contacts? In that case the problem would be with all lenses attached to that body...

The camera exchange suggestion is good if possible but I suspect it will work the same...

The issue may not be with the camera contacts but with the lens contacts.  The camera contacts align slightly differently between bodies and any dust or grime on the contact can cause a problem for one but not the other...particularly since this is an older lens.

May not be the problem but it's an easy fix if it is.

I bought the 7d mark ii two weeks ago and its a great camera.  However I have a 70-200mm mk1 2.8 lens there's times I'm trying to shoot and it won't shoot/focus and what not.  However on my regular 7d with that lens I don't have that issue.  I realized the when the af jumps for my 70-200mm lens on the 7d mark ii it stops focusing then maybe after a minute or 2 its working fine then it could happen again.  I tested my 7d mark ii with a tamron lens (24-70mm with VC its no issue with that) So I'm ruling out as a body issue but the lens works perfectly fine on a regular 7d it jumps here and there but still remains to focus.  Just wondering if anyone is experiencing this issue.  Also I realize the flicker warning  is going off with both lens but the test is just with regular lamp lighting.

I only have the 70-200 mk ii but have not experienced anything like that with my other lenses.  You said that it's working with other bodies...it's still possible that the lens electronic contacts are dirty.  That would be something to check and clean.  Dirty contacts can cause so many sporadic issues that its the first thing I usually suspect. 

Also if the lens works fine with other bodies then it's not likely the lens.  It wouldnt be intermittent one one body and not on another.  Therefore I suspect it may be contct related or something with that camera body.

If the contact cleaning doesnt work, you should consider going back to the dealer with your lens to try another body and see if it's yours or something related to the 7D in general.  Are you able to still excahnge the camera if needed?  If it's within your exchange window you should just do it and not wait too long.  Otherwise the only recourse willl be to send both lens and camera to Canon and have them iron our the problem.

Thanks for the follow-up and the update. Much appreciated. As you predicted, follow up testing demonstrated iTR had so effect on issue #4 for me. GPS working fine for my uses. Battery drain still a concern with GPS but seems to have leveled off for some reason. I'll probably only activate it consistently for travel work.

I think the leveling off issue is completely normal.  I see that in mobile phones and laptops.  The devices have to learn the drain rate in order to predict % battery usage.  GPS will drain a battery as its on all of the time when enabled even if power is off.  This is why you can minimize the drain by having it update on the longest time schedule.  If you disable it, you run the risk of it taking longer to sync up when you need it...as well as drift in the clock.  I guess we will figure out in time how much the GPS drains the battery.

A couple of updates on 1 and 4.  The noticed lag seems to occur only when the camera comes out of sleep mode and only with the 300mm f2.8l is II.  All other lenses I own snap right to business.  It also seems more jittery.  Canon suggests tweaking the tracking sensitivity down a bit for this lens and see if it calms down a bit.  Still a work in progress.

#4 required more tests side by side with my 5diii and a call to canon.  The zone AF issue appears to be a result of having more AF points on the 7d2 than on the 5d3.  The zone is also larger on the 7d2.  Careful tests between the two show similar issues of not locking on forground subject.  However on the 5d3 this is masked by the zone having fewer points and therefore less info to lock onto something else.  7d2 behaves more like 5d3 when the foreground subject is about the same % of AF field as on the 5d3.

It's not a bug but just the camera trying to do what it's supposed to do.  Canon will report it for investigation to see if tweaking the algorithm is needed.

#6 I'm having good GPS response.  Need others to report on their experiences.  I suggest when it's first enabled to let it update every second, then once you get a GPS lock and leave it enabled, set it to update once every 15 minutes or more often when you go on site.  In the bag set it to the maximum setting to save your battery.

All of the others, please share your experience with these configurations so we can determine if these are systemic issues or one offs.  Canon does pay attention to reports but we have to contact customer service to get it in the queue.

Thanks.


OK Here is a summary of issues we are tracking for the 7D Mark II:

1) Fraction of a second AF lag(lock) on half press (w/300mm F2.8L IS II)
        Still looking for confirmation and a repeatable process

2) Shutter not firing 2nd volley when rear AF-ON set to AF-OFF and pressed first
        This is confirmed and likely fixable with a firmware update

3) Manual AF point selection is retained seperately for each AF mode (can default be set back to center?)
        THis is confirmed.  Still looking for a workaround

4) Zone AF not always locking on closest subject
        This is confirmed by several users.  Inconsistent forground lock.  Needs fixing.

5) 3rd party flashes not exposing properly when used as a wireless slave.
        Looking for more tests.  Does not seem to be an issue for Canon flashes.

6) GPS does not seem to work reliably
        Long delay to get GPS to work when new out of the box.  Could be normal as GPS's often need more time initially to find themselves on the globe.  More reports needed on how GPS is operating for them.

Some of these looked like iTR'ish like symptoms but with iTR off problems persist.

IF you have anything to report on any of these or have any new issues to report, please share.

THanks
OP
