I prefer this tracking system for travel use.

thanks, seems like a good value.

Holds a lot of weight too.  I can get my 600 F4L with my gripped 5D3 on it but need extra counter balance.  But it works.  With my 300mm F2.8L it's a perfect balance with only one counterweight.  You would likely need the wedge and a couple of other things so if that seems like a good value, make sure you get everything you need.

I have both the 7D and the 7dii. I had the 7D for nearly a year and the 7Dii was supposed to be  an upgrade for me.
Both cameras were set to the same exact settings (or as close as possible given that the shutter speeds have slight variations, etc.).  I was shooting horse races using both the 70-200mm f/2.8 L IS II and the 3oomm f/2.8 L IS prime lens.  On day one I used the 7D and 7Dii with the 70-200 lens alternating cameras one race after the other.  On day two I alternated cameras race by race using the 300mm.  RESULTS:  Both the 7D and 7Dii shot identical quality shots using the 70-200mm.  Using the 300mm prime lens, only the 7D shot in-focus shots one after the other.  Nearly every shot taken by the 7dii was blurry.  I spent a solid week testing and retesting.  Same results.

There is something inherently wrong with here.  Compatibility issues? Maybe?  I sent the 7Dii back to B+H which honored their 30-day return policy.

Now my search for an upgrade to the 7D continues.  I thought the 7Dii would be that upgrade but it turned out to be a huge disappointment!

If it's any consolation, my 7d2 is back at canon being checked for AF issues.  In my particular body even afma was not being honored properly.  I could get fairly consistent in focus shots using one shot AF but in servo AF it required a different afma...and would not be consistent from one day to the next. 

Though they are full frame, the 5d3 or 1dx are the next options.  For crop sensor the option would be the 70d.

Hi.

I really love the results from my 600mm mk2 together with my 5D mk3 BUT I find it very hard to focus with. Like yesterday for an example. The main target was about 30m away. I had the setting on "16m and further away" because there would be no objects closer than that. But when I try to focus on the trees in the background that was about 200m further away it had big issues to find focus even though I think that the background had some contrast. I needed to use manual focus first and then it did focus properly on that distance. When I then wanted to set the focus again on the subject 30m away from me I again needed to use manual focus first. I tried several solutions by using more or less autofocuspoints and change the settings in the camera but I feel that the lens or the camera is struggling more than I expected. I have no friends with a lens like mine so I have no one to ask or compare to. Maybe the camera and lens is no better than so and that is what to expect but I find that hard to believe. Trying to catch flying birds is also really hard because I often need to focus manually first to somewhere close to the distance of the bird and then I can use autofocus. Can someone with own experience write about how it works for you? The examples are many when I have had a hard time getting the object in focus.

Thanks.

There is a setting in the 5DIII firmware to only use cross type AF points.  That helped considerably.

EOS Bodies / Re: Canon 7D Mark II Metering / Extreme Overexposure Issue
« on: February 23, 2015, 07:34:42 PM »
Hi, I have a brand new 7D Mark II and I'm experiencing intermittent metering issues. For example, I will be shooting just fine in aperture priority in a normal outdoors environment, say at F4.0 at 1/250 sec at 400 ISO, and then all of a sudden, the camera will show that it needs a 30 second exposure (on the LCD screen on the top of the camera). However, if I switch to live view, the screen on the back of the camera will show a normal 1/250 sec exposure. When I switch off the live view, the top LCD screen will go back to showing some ridiculously long exposure time.

Changing shooting modes (TV/Manual, etc.), metering modes, AF modes, etc. seem to have no effect on on correcting the crazy long exposure time. However, after a minute or so, things will go back to normal.

Has anyone else experienced this phenomenon? Thanks for advance for your input.

That is not normal and while I sent my 7d2 back to canon for other reasons, I never experienced this issue.  Check the electrical contacts on the camera and lens for any dirt or lint.  If that's ok, can you try another lens and see if the problem still happens?

If you don't have another lens, try to find a series of steps to reproduce the problem and send the lens and camera back to canon for replacement or repair while it's still under warranty.

Photography Technique / Re: What is your keeper rate?
« on: February 22, 2015, 01:00:00 PM »
Keeper rate

1dx = 95%
5d3 = 85%
7d2 = 10% sadly

7d2 is back at canon for an evaluation.  Also note these percentages are shots where the camera performed properly...doesn't account for my bad timing.

A very interesting conversation for me because I have been pretty disappointed with the 7D Mark II.
I have very good eyesight and the view through the viewfinder and a 100-400 L II is really very good.
The camera looks as if it's locking on focus extremely well.
The photos however I am finding are disappointing.
I would say quality wise no better than my old 500D.
I had though APS-C sensors had come along way since the 500D but it doesn't seem so with my copy of the 7D Mark II.
It's a lack of resolved detail I'm finding most disappointing.
Maybe I'm spoiled by the 5D Mark III but I find the pixels seem to smudge into each other alot earlier than I am expecting. No better than a 500D sensor.
I understand it's a cropped sensor but I thought at 20+ MP it would resolve detail better.
Photos do look a bit soft compared to how they seemed through the viewfinder.

Could these issues be caused by an AA filter or something similar that was intended to smooth out noise at higher ISO's?  Or maybe something in the in-camera processing of the image?  I can't imagine the actual sensor tech has taken a step back...

(I know this question in various forms has already been asked in this thread, but I was hoping some our more engineering enlightened members might chime in.  ;) )

Almost certainly the AA filter softens the image which requires post sharpening either in or out of camera.  However the AA filter will not affect AF, at least with phase detect AF it wont.  Most of the issues are with AF problems.

AA filters were introduced to reduce moire patterns, particularly in video.  If you shoot mostly wildlife and natural landscapes moire is not an issue...though you can get it on feathers of birds in some situations.  The AA filter seems particularly strong on the 7D2 and could be due to the smaller pixel pitch and their anti-moire requirements.

Thanks takesome1, as you've already probably gathered I tend to fuss and fume tooo much.  I'll have the 1D IV in a few days and it'll have to do and I'm pretty confident it will do.  :-[

You will enjoy the 1DIV and never look back.  Once you see what it can do, all of this discussion on the 7DII will appear as silliness.  :)

I do use other lenses. Here is a great tit taken on the 7DII + 300/2.8 II + 2xTC. A guy next to me had the same lens combo on the 7D, and it would not focus. Mine was fast and good.

Yes but this is a static shot where one shot AF would be sufficient.  Try some bird in flight shots and see how many in focus shots you get in the sequence.

I have no axe to grind about FF vs crop or the 7DII vs 5DIII or the 100-400mm II vs big primes because I use combinations of all of them according to circumstances.

First, the AF on both my 5DIII and 7DII is fast and consistent in A1 servo, and my keeper rate is very high. The same was not true for my 7D, which could not even cope with some lens combination.

Second, I use the 5DIII + 300/2.8 II + 2xTC III for bird photography, accompanied by wife who uses the 7DII + 100-400mm II, both camera systems having about the same field of view. The quality of the images from the 7DII are excellent, though not quite as good from the 5DIII, despite the 100-400mm II not being in the same price league as the prime. My experience is that the 7DII + 100-400mm II at f/5.6 is as sharp at the centre as the Tamron-150-600mm on the 5DIII at f/8 and sharper at the edges.

I simply do not understand why some users are getting only 5% keepers and have AF problems. Some used to say the same about AF with Tamron 150-500 on the 5DIII, but I never had any problems. Perhaps I have been very lucky with my 7DII and 100-400mm II etc. But, whatever, some copies of the 7DII do really deliver the goods.

Perhaps you are of are one of the lucky ones that got a good copy.  There are very numerous and consistent faults with the AF system and I would recommend anyone considering a purchase to hold off a bit for canon to figure out what is going on.

So which would be a better choice for a 6D owner, if one is looking for the best all-around camera, the 7D II or the 5D III?

Absolutely right now I would get the 5d3.  Too many issues with the 7d2 right now.  People are only getting about 5% keepers in servo AF.  It's slightly better in one shot mode.  However the AF system has some big issues that are not getting resolved by canon.

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.

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.

I concur with all of your statements.  I believe there are multiple issues that are not related.  After a lot of testing I'm also finding that AFMA does not seem very consistent.  That meaning one day afma 0 is good but several days later with the same lens afma 6 is better.  Same lens on my 5d3 is perfect.  One would then suggest that there is a physical issue with the AF sensor moving...possibly...but could also be a firmware issue where afma is not always honored.  No one but canon can make that determination.

1Dx & 400f/2.8 II @ f/2.8

I guess it won't be long now & this thread will be somewhat defunct, everyone will be posting to the 1Dx II & 5Ds/R threads.

Still, until then, the 1Dx has been without a doubt the most satisfying piece of Camera gear I've ever used.

It wont be dead as long as you keep posting these wonderful cheetah pics.
