EOS Bodies / Re: Ron Martinsen Blasts the 7DII in his review
« on: Today at 02:30:06 AM »
Here´s a short video, where he is demonstrating the fantastic (in his view) autofocus with facial recognition on the D4S:
https://www.youtube.com/watch?v=nInuePLiO1k
Even for a totally still, well (over)lit face, it still hunts ...

In his D4S review, which he claim has the best AF system in the world, he is using his kid on a swing, as "the ultimate AF challenge" ::)

I have played with the 7DII for some time now and to bash its AF system can only imply that they guy either had a poor copy or he does not know what he is doing. I used it this weekend to shoot small birds, jumping around in trees, with the 600 f4L IS II and the 1.4xIII extender. At 1/640s, f5.6-6.3 and ISO 3200-5000, my keeper rate is high, so how he managed to have problems with large slow moving subjects (people), in high contrast outfits is beyond me.

I have not tried the D4S, but I don´t remember having seen any review claiming that it has a better AF system than the 1DX, which I know very well. And I have seen for myself that the 7DII stands up very well to what the 1DX delivers, at a fraction of the price.

As for ISO performance, I, like many others, would have liked to see a greater improvement, but it is an improvement. And as for body ergonomics, I have absolutely nothing to complain about. Well, I´ll correct that; I would have liked the AF mode switch to work both ways, so I didn´t have to run through all modes every time (I can live with that ;)

I do believe I have read my last Ron Martinsen review ...

Third Party Manufacturers / Re: Have you repaired your 50 Art?
« on: December 19, 2014, 02:56:18 PM »
Hi,

I'm new here so kindly forgive my ignorance.

I sold my old system (5D Mark II + kit lens + nifty fifty) a while back in order to pursue a different art for a while. Am getting back to photography and have been researching the kit I want and am on the fence about the Sigmas - both the 35A & 50A. My camera will be a 5D Mark III and I've decided on buying only prime lenses. I foresee using the camera for general travel shots, landscapes & seascapes with an occasional astro when opportunity presents itself.

I'd like to know if these lenses exhibit the random front/back focusing problems only when using auto focus or its the same with manual too? I can't afford a Zeiss (non Otus as well) and if these lenses provide me with the IQ comparable to Otus at a fourth of the cost, I'm more than willing to ignore the auto focus and use manual full time. Since, I'll be using manual focus most often, should I invest in the sigma dock just to be able to do AFMA and try my luck with the AF as well?

Thank you for reading and hopefully helping me make the buying decision.
Manually focusing the Sigma lenses is a lot more difficult than focusing the Zeiss lenses! Unless you are willing to trust the AF system on the Sigma lenses, don´t buy them!

That's an expensive habit you've got there.  Is there a twelve step plan available? :D
Well, you may spend all your money on lottery tickets, or try to become the CEO of a fast growing and profitable IT company or you can go all in for a career as a rock star :)

PS! I don´t buy lottery tickets and I hardly sing in the shower ;)

Animal Kingdom / Re: Show your Bird Portraits

Verdin.  These little birds are a common southwestern US species, easy to find, hard to photograph.  They like to forage within the foliage of small trees and large shrubs and one seldom gets an unobstructed view of them.  I got lucky.

Canon 5Diii, 400 DO, ISO 400, aperture preferred setting, f6.3 @ 1/1600.
Three things about your image.
One; you managed to point your camera, compose and get the focus right, before it was off. You say lucky, I believe there is something more.
Two; All the obstacles between you and the bird is gone (greatly appreciated by those who have tried before you ;))
Three; It shows that the 400 DO vI actually was´t all rubbish, like some seem to believe!

Canon never do giant leaps. They do things in a proper order. The sensible thing to do is to release a high resolution camera for studio and landscape work, where the number of changed components can be controlled. A 5DIV, with no AF gamble, no memory card gamble, no new computing platform, no new internal bus architecture etc. makes perfect sense. Personally I would prefer a 1DsIV or 1DX-II (you choose), but I suspect I will have to wait. But with my newborn addiction to manual focus Zeiss lenses, that may be what I should be waiting for ...

Here is one more from my weekend´s walk. At this time the light started to fade, so I had the 1.4xIII removed and shot at 1/500s, f4.0 and ISO4000 (still 7DII and 600 f4L IS II)

If you have not photographed small birds before, I suggest you give it a go. They are SMALL as in TINY. And they don´t sit still. First you have to spot them, then you have to find them in the view finder, with the lens totally off focus, then you have to focus and compose and push the shutter release and you have about 2 seconds to do all that before the bird is on the next branch. This is not recreation, this is stress  :-X

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 :)

Lenses / Re: Informal comparison of old and new 100-400 + 500 V.1
« on: December 18, 2014, 01:26:25 PM »
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.
