And it is a mini 1DX. It doesn't have the IQ or frame rate as the 1DX either, but people aren't saying that is an issue.

Neither does it have the same number of dual cross AF points as the 1DX or 5D3.

It's fair to say the AF SOFTWARE is similar to the IDX but to say the total AF system is the same is not truthful.

It's like putting Photoshop onto a PC with 512mb RAM, core 2 duo processor and no graphics card and saying it will perform almost the same as the same version of Photoshop on the latest and greatest Mac

The more bodies you go through the less likely it is that it is a camera issue. Think of it like this, if 2% of bodies had an issue out of the box, then to get three bad ones in a row is 0.0008%, or 1 in 125,000. Not saying it couldn't happen, and the 'failure rate' is a complete guess, but is in line with average failure rates of 5% in the first 12 months for consumer electronics.

Statistically you're 100% correct and I do wish that when I got my second body, it worked 100%.

Canon Africa's senior technician ran diagnostics on the first two bodies and advised both were problematic.

The diagnostics have been sent to Canon Europe for further analysis. I asked if I could get a written report but that was essentially declined.

I was expecting to have a hit rate of maybe 70% for birds in flight but my current ratio is maybe 30%.

I'm not saying there isn't anything wrong with the 7d2 (I don't own one), but I'm interested anyway ... did you make sure you experimented enough with the tracking settings? This makes a very large difference on how much keepers you get...

... for example with optimal settings I can crank up my 6d up to a 10% keeper rate with the outer points :->

Very fair question.

I have invested many hours researching the sliders and fully appreciate that I am yet to nail perfection as far as that goes.
Tracking sensitivity and AF point switch I find less complicated than the acel/decel slider.
Acel/decel is, as far as I understand, critical for subjects that don't move in a straight line. So a bird that banks, dips or dives. Perhaps sudden change in speed.

So I am work +1 now for acel/decel but what I don't know how to measure, is if there is a measure of TOLERANCE if I select +1 but 0 may be marginally better.

That being said, it's not very satisfying to have a series of shots where my focus point is on the bird throughout the burst, yet 1 of 11 shots are sharp. Next attempt, same bird, same settings and then I get 4 of 10.

Are you working with ITR on or off?

I leave it on, even if it only works when all 65 points are active

There's other videos of Canon pros who intimate that although not identical, the 7Dii's performance is very near to that of the 1DX.


Thus the issue for most of us, we were expecting these "Canon Pro's" not to lie to us.

The 7D II's performance is not 1D caliber.

But it is however the best AF system in a crop body. It is better than the old 7D. It is the best AF system in a body under $2,000.

Really what should we have expected for $1,799?

I would have expected a camera with a better than 10% keeper rate in servo AF mode.  This camera is fine for Harry homeowner taking shots of his kids playing in the yard.  It is NOT a body I would trust on an expensive trip or assignment.  Not in its current state.

The system for all practical purposes is useless if you can't get better than 5 or 10% keeper rate.  My daughters t2i does better than that.

Less than 10% keeper rate would be unacceptable surely. Maybe there is some problem with the camera.

I can't say for others but my 7D2 seems to be focusing fine so far - I would place it at par with the 5D3 based on the 100+ shots I took in the evening today.

The story of 10% keeper rate is fairly common, I have to verify that rate.

Here's something I find totally mad. I've been told it's a batch issue, yet! Not every 7Dii that is not performing, exhibits the exact same problems. Some have sharpness issues. Others have AF issues. Others have both. Then there's the issue of focus locking on objects that occupy less than 10% of the frame. Example would be a kingfisher vs heron. Heron is perfect, kingfisher not at all.

Rahul, may I ask what you were shooting?

Hi Sabaki,

I was shooting 3-6 year old kids playing outdoors. The AF tracking worked quite well in AI-Servo. This was my first day with the 7D2 though. I hope this isn't a Jekyll/Hyde camera as some have experienced.

Birding will start tomorrow, weather permitting - it was a very cloudy day today.

Focusing on very small subjects was a problem I faced consistently using the 100-400 V1 on both my 5D3 as well as the 6D. What lenses are you using on the 7D2 which are causing this problem?

Rahul, I really hope yours is 100%  :)

I don't know if you can sense my anger and massive disappointment about my experiences with the 7Dii, it's stolen my desire and enjoy of photography.

Best of luck mate, holding thumbs yours is perfect

I firmly believe the engineering on the 7Dii, whether software or hardware, is flawed.

I've had three copies of this camera now and can tell you with great confidence, this camera does not perform to the standards Canon's promotional material suggested.


Did you get all this three cameras from the same source/shop?

My first camera was from a retailer and the next two directly from Canon.

I've been asked this question before and unless the retailer drops the box or hurts the camera in such a way, we get handed sealed boxes.

Hi Orangutan

I consider your opinion reasonable and logical. I do however have enough evidence to support the performance issues of the 7Dii.

I take you back to Scott Kelby's hour long video where he highlights the superb performance of the 7Dii at two American football matches. Shots looked amazing, for both sharpness DNS noise performance.
There's other videos of Canon pros who intimate that although not identical, the 7Dii's performance is very near to that of the 1DX.

So we've all probably seen those and more videos.

Thing is, when I sit with owners of the 1DX, both professionals (international event sport photography) and serious birders, who cannot get decent performance from the 7Dii, I worry.

I am talking about seriously good photographers here.

Aside from AF and shsrpness issues, there's also this extremely weird 'work one day, next day not' phenomenon. Set your camera up, take good shots. Go to the exact same place with similar conditions and then the camera behaved very differently.

I can't grip that.

We also talk about the vast number of people who are not complaining and I can tell you something there too...most of the regular buyers do not know how to benchmark whether an image is sharp or not.

I'm a photographer/birder, meaning I strive for photographic excellence in my shots. There's also birder photographers, who are more keen on proof shots. It seems they're less worried about perfect photographs.

I'm hoping and praying that Canon fix this or I may end up selling my 7Dii.

Absolutely nothing worse than having a camera one does not trust implicitly.

Hello Sabaki

I have a 7D2 since December, and I took it out, mainly for bird and wildlife photography, for in total about 15 days. I used it on the Tamron 150-600, the Canon 300mm f4 L IS, the Canon 100mm f2.8 L IS Macro and the the Tamron 70-200 f2.8. In one-shot mode it performed very well with all these lenses, no sharpness issues at all. In AI Servo I had some problems with the Tamron 150-600, many shots were out of focus although I used only the centerpoint extended by 4 sourrounding points and the focuspoint was firmly locked onto a birds head. With the 300mm f4, the 70-200 f2.8 and the same AI Servo settings, the results were much better. And since I also used a 5DIII on the 150-600 and expericened the same amount of unsharp results, I guess the cause is most likely my technique or (hopefully not) the lens.
I will soon try the 7D2 on a Canon 100-400mm II which I can borrow for some days.

Hi geonix

The issues with the third body is in AI Servo mode.

Now, knowing that all those Cases work ONLY in AI Servo mode, my feeling is that the issue is either the physical SF points, software or perhaps a combination of the two.

I was expecting to have a hit rate of maybe 70% for birds in flight but my current ratio is maybe 30%.

There's nothing handicapping the 7DII in the tests, Marsu42.  My 60D is sharper than what is shown, and you can see that for yourself if you choose the 60D as the body in several comparisons.

The 7DII is not being cropped in any strange way.  It is a straight test of sharpness, of how the lens is resolving a test chart, and the 7DII with the ef 100-400mm II, a theoretical "dream team," is having some kind of trouble in this instance.

Arthur Morris deals with some pretty experienced enthusiasts, yet he dismisses their claims as user error.  Are you saying that Brian at the-digital-picture set up his tests incorrectly?

The whole crop vs ff issue doesn't come into play here.

The first question I ask in these cases is whether there are people out there who are getting the expected results from this camera.  If the answer is yes, then we know (fairly conclusively) that it's not a design/engineering problem.  At that point there are two main possibilities: quality control (i.e. manufacturing variability) and user error.

Go hit the web again; this time, look for satisfied pros/advanced enthusiasts who don't have a business relationship with Canon.  If they're happy, you need to look beyond design flaws.

There's problems locking onto subjects, there's problems with softness, there's problems with AF performance...and before anybody takes my head for saying that, those were the words used by Canon SA when explaining issues with my first two bodies.

Softness was a BIG issue with the second body and according to Canon, they could not reconcile the issue and instead gave me a third body. Which is also not perfect.

Let's hope that when new firmware is released, it will solve of these issues.

If I sell my 24 T-SE II and MPE-65... :'(

No man! don't do it  :-[
I'm thinking about selling some of my under-used gear to fund this one.  My 24L II has seen little action since I stopped shooting events and bought the 24-70 f/2.8 II, so I think it can go.  I'm actually considering selling my 16-35 f/4 IS as well.  It's a spectacular lens, but I don't know if I'll use it a whole lot with the 11-24 f/4 and 24-70 f/2.8 II combination.  The TS-E 17 f/4 is another candidate because I have the TS-E 24 f/3.5 II as well, but T/S lenses are so unique, it's hard to think of giving up that lens.  First world problems, right?

You guys have some spectacular kit for sure.

I have abour $3000 free a year to buy the things I want, so it is taking me a while to get everything I want :)

This year will be a toss up between a 5Div or a 11-24 for me. I can only do one

Feel free to courier that 17mm TS-E to me. I'll hold onto her until you decide what to so with it  ;D

My first question would be, is this a dedicated macro lens that only does macro?

For the engineers and technicians amongst you: Is it at all physically possible to gain greater depth of field by changing the lens design or perhaps the distance to/from the sensor or is this relationship set in stone?

If I could dream...internal lighting that will illuminate your subject with 100% beautifully diffused light!

EOS Bodies - For Stills / Re: POLL: 5Ds/5DsR first impressions
« on: February 07, 2015, 07:11:17 AM »
I'm not impressed.

I just wanted two things: better DR and better base ISO performance.

Canon are touting this as a landscape lens and from their point, it goes up against the D750, D800 & D810.
For me, it's not being able to take similar pictures those those aforementioned cameras.

Now before anybody hits me with a 'smug-plug', all I'm going to say is why should Canon expect me to buy this camera?

I can go buy a 12-24 & D800/D810 for similar money.

11-24mm on full frame

16-38mm on crop (not really, but close enough)

VERY interested to see the specs on this. It would be a massive spend for me but I would much rather spend $3000 on a lens than a body
