Another from my weekend walk with the 7DII, 600 f4L IS II and 1.4xIII extender. For the first time (at least as far as I can remember) I had too much reach shooting birds. This blackbird (only cropped slightly on the left side) jumped from that branch and a little bit closer and then I could not fit the whole bird in the frame. Never thought I´d have that problem :)

One thing about the 7DII though, being used to the 1DX. The view finder is not in the same league.

1/640s, f6.3, ISO5000

The 7DII is chewing 20,2MP at 10fps and its buffer handles an infinite number of jpegs and about 30 RAW. Which translates to 4 fps and 12-13 RAWs in 50MP terms. But that is if a new camera is a copy of the 7DII for every thing else but resolution. Is that very likely? The 50MP camera comes a year later, will cost more and can justify more computing power, can use faster memory cards etc. etc.

The thing is, what's limiting Canon most at this point seems to be their USB bus speed:  Their SD card readers cap out right at the USB 2.0 maximum typical speed.  Canon needs to upgrade their SoC to a modern core and shift image processing functionality into dedicated GPUs.  If they did that, they'd be able to have two uncrippled UHS-II SD card slots writing at up to 512 MB/second—four times the maximum speed of CF, and fast enough to do 20 frames per second if you alternate between cards.  Of course, cards with such speeds don't exist yet—right now, you'd only be able to do about 10 fps continuous when alternating—but IMO it is critical that Canon stop shipping these dog-slow SD and CF card slots and move to proper UHS-II slots so that their reader will stop being the main bottleneck.
Exactly!

50MP, improved AF, improved DR, improved noise, (near) equal high ISO performance and 10 fps (will require modes to support reduced image sizes in some cases though). That would be a dream camera and I will promise to be a good boy for a loooooong time :)

It seems to me that your samples indicate that the new 100-400 even outperforms the 500. If I see more examples like that, the temptation will be just too much to handle  :P

I have not posted much here lately. Might have something to do with the lack of new bird images ...

I have had the 7DII for a couple of weeks, but have not used until this weekend. Took it for a walk in the woods, with the 600 f4L IS II, with the 1.4xIII extender, giving me the full frame equivalent of 1344mm, which is quite impressive. The main reason for buying this body was to see what I could get in the long end. The AF system is very good and a tremendous improvement over the MkI. I was concerned with ISO performance, so I wanted to test that also.

So this is a slightly cropped images of a tit (feels odd every time to say that) at 1/1000s, f6.3, ISO5000. I have applied some noise reduction and boosted saturation a bit, but only a 3 minute job. If I had shot this with the 1DX ... It would at least have been cropped quite a bit. All in all, I am fairly happy.

Lenses / Re: buying advice: canon 85mm f1.2 II or f1.8?
« on: December 18, 2014, 04:49:59 AM »
Now if you're good with that lens you can get some of those shots but shooting wide open your going to have a low keeper rate compared to lenses like the 70-200 2.8 IS 2
At least lower. But if you shoot the 85/1.2L II at f2.8 or higher, which would be a more fair comparison, your keeper rate goes up. It will not reach the 70-200 f2.8L IS II, but it will be a lot better than at f1.2.

By the way, the AF speed bashing has not been bad in this thread. I have a feeling more of the enthusiasts have posted here. But you´ll find numerous other threads, where (in my view) too many are throwing unfounded/incompetent/... (you choose) venom and bile at its AF system. The one thing I don´t like about it though is its focus by wire electronic manual focus. I never got the hang of that.

Might a 1DX/7D2 provide powerful enough focus for the 85/1.2II to be fast enough? Anybody have any experience in this?

They might help a little. But not really much. It's just how the lenses were designed.
AF is faster on the 1DX, compared to the 5DIII, but it is still no race car. But my experience is that for regular use, where your focus only need to change a minor distance, it is fast enough. The challenge, when things start to move, is not focus speed, but to determine where you want that millimetre thin DOF. If this is a lens you pick up every now and then, it will probably not give you much. But if you practice and use it extensively, it delivers images you can´t get from any other AF lens (The Otus is in a league of its own, but requires even more practicing and dedication due to its manual focus).

A lot of people bash the AF speed of this lens (and I suspect many of them have never truly used the lens). But I think we should appreciate the challenge of making an AF system accurate enough for this lens at f1.2. As a comparison, the focus ring on the Zeiss Otus 85/1.4 travels about 220-230 degrees. How slow would that have been as an AF lens?

Highly doubt you'll see much more than 4 FPS from any cameras wielding the next gen of high MP sensors in the near future. 
The 7DII is chewing 20,2MP at 10fps and its buffer handles an infinite number of jpegs and about 30 RAW. Which translates to 4 fps and 12-13 RAWs in 50MP terms. But that is if a new camera is a copy of the 7DII for every thing else but resolution. Is that very likely? The 50MP camera comes a year later, will cost more and can justify more computing power, can use faster memory cards etc. etc.

If this camera includes a sensor that is a D810 basher, with even better DR, noise and ISO performance, then 4fps may be enough. But if it is merely a 50MP "7DII" sensor, it needs to include some other jaw dropping functionality, of which buffer size and fps are two.

Canon EF Zoom Lenses / Re: Canon 100-400mm f/4.5-5.6L Mark II

This looks very good! I´m looking forward to see more of your images and hearing more of your experiences with it.

I don´t need this lens, but it is very tempting as a light travel companion. My threshold for carrying the 200-400 is there, when weight and volume is an issue. But this lens mounted on the 7DII will be quite potent for some of the things I do. I never liked the MkI, but this one looks better and it is clearly very sharp in the centre.

7D MK II Sample Images / Re: Anything Shot with a 7D MII
« on: December 17, 2014, 10:50:33 AM »
I have had mine for a couple of weeks, but I have not had the time to play around with it much. But last weekend I took it for a walk in the woods and managed to shoot some tits (sounds odd to say that :)).

This one was with the 600mm f4L IS II, with the 1.4xIII extender, which makes it a FF equivalent of 1.344mm(!). Awesome reach! I have not done any AFMA, but it seems to be pretty good out of the box. The AF system is very good, no matter what you put it next to.

My biggest concern has been the ISO performance. I have seen Scott Kelby show off ISO16000, but I do not believe that is a realistic level for anything. I would be happy though if I could use 3200, so this is a 3200 example. Considering my expectations, this is good enough for me. I´m sure that someone with better post processing skills than me, easily could push it 2 stops further.

1/640s, f6.3, ISO3200

The 5DIII will be 3 years old in March next year. A move to 50MP will pretty much follow Moor´s law. That same law should indicate just over a doubling of its computing power and given the speed of new memory cards, we should a least expect a camera that could chew 50MP at a slightly higher speed than the 5DIII and thus see at least 6, probably 8 fps.

As for AF system, there is no reason not to expect something beyond what the 7DII have. And I don´t see why we should´t expect more intelligence and speed in the processing part of it. More AF points, better tracking, better coverage of the image area etc.

The big questions for me though are what we will see in terms of DR, noise and ISO performance. A 5DIII just ramped up to 50MP and the rest same same ... Not tempting enough.

Eldar,
I have to think about this.

MF is something I always feel out of my comfort zone. Although I haven't try on 1DX with Ec-S, however, I did on A7 series with Canon and Zeiss A-mount lenses(focus peaking mode). The results were not on par. I'm sure is not the gear problem.
Don´t be put off by having tried to manually focus AF lenses. A Zeiss is a totally different beast and a lot easier to focus.
Alternatively you only have one current option, the 35L. It is being bashed by the chart porn readers, but it is still producing beautiful images ... The Sigma Art could have been an alternative, if the AF was fixed.

Very tempting as a low weight and compact companion for travel and hiking ...

14
On average I would estimate about 1 smartphone image pr. 5.000-10.000 DSLR images. I only use it to photograph whiteboards at work and that does not happen very often.

I'm in need for 35mm fast prime. I guess I can cross the ART off my list for now.
Dylan; Before you make your decision, try out the Zeiss 35mm f1.4, with an Ec-S focusing screen in your 1DX. Play with it for a while and I´m sure you will discover that manual focus is less of a problem than you would think!
