You should name him Churchill. He reminds me of Sir Winston.

The issue of poor focus due to heat haze was supposed to have been addressed in this camera, according to Canon in their launch promotion material. I'm hoping that is the case, as its one of the reasons I jumped in to purchase. Whilst we don't suffer from a lot of heat in this part of the world, we do suffer a lot from heat haze from road surfaces, particularly around mid-day period, which has long been a fly in the ointment for many Canon users who shoot motorsports. The camera's AF would rarely lock on to the subject and trying to get a sharp shot from distance was often a nightmare.
The only solution, which seems to work, is to shoot down from a stepladder to get above the visual disturbance between you and the subject. So apart from a bag full of big lenses, spare bodies, laptop and other accessories add a stepladder to the mix and a days motorsport shooting suddenly becomes an expedition requiring sherpas. Add in hiking though fields, over hedges and ditches and you soon discover how fit you really aren't.

Just get 'ya a pair of Spock's rocket boots. Problems solved.

Funny testing....

I agree

Very nice. Are you absolutely sure the aperture was at f/1.4? It looks a bit stopped down to me.

Uploaded from my cell, but first underwater session where I used the 1DxIII for stills and not just video. Performed exceptionally!

I know you posted these some time back but......
I did not realise what super images the 50mm 1.2 could produce.

I've steered clear of the lens so far as its reputation was not great.
I owned one years ago but that was on an entry level camera.

Those who criticize the EF 50mm f/1.2 L the loudest are the same ones who think the end-all be-all for a lens is how well it shoots the edges of flat test charts when optimally focussed on the center and never get out and actually take pictures of a three dimensional world.

DXO scored MKIII below MKII. Why? Because it’s 2020. Nothing makes sense anymore!

Something is definitely screwy with their testing. Either that or Canon has increased the shadow recoverability by basically forcing the camera to shoot one stop to the right when using the same metering as with previous models.

Look at the ISO sensitivity measurements. The 1D X Mark III has higher sensitivity at one full stop lower settings than other cameras do at the next stop up!

Almost all manufacturers typically make sensitivity slightly lower than nominal to protect the highlights. DxO measures the 1D X Mark III at almost one stop brighter than nominal and a full one stop brighter than the measured sensitivity of the 1D X Mark II and 5D Mark IV.

Thanks and definitely f/1.4.

I've been able to shoot my 1DXIII more often lately / finally. Still not a TON, but a good bit.
Overall have been really enjoying it, over my 7DII I used to use. Sometimes i miss the pixel density though / still would have liked maybe 28MP on this, but its ok.

The main things I still have issues with though, are with autofocus in some situations.

Optical:
I was testing full auto in optical, on birds flying on a clear sky. But sometimes it can AF fairly slow it seems like. Or not as fast as my 7DII in those cases.
Maybe i need to use the Instantly focus on stuff AF Case, or something else. Although generally it's OK.... but full auto also can grab bird wings more often, so i still generally stick to 1 pt or smaller group. Unless the birds really going crazy in the frame, then full auto probably is better.


Live View:

This one annoys me the most, with AI Servo. For static stuff, its awesome. Overall super fast/accurate/etc.
But again, I was trying to focus on a great blue heron, right over my head, clear sky, and it WOULD NOT FOCUS. It kept ALMOST locking focus, then slowly go past/come back/etc and just hunt and hunt and i lost it/never got any shots. I was using the AUTO case I think. Again, maybe I need to use Case 1 or a faster one to force it to move quicker, if possible. I do wish the single point in Live View was like 1/2 the size as well.


Has anyone else had slower/not as good of luck with the Live View AI Servo? Might be my lens too, as I use the older 500 F/4 L IS.

Your first question--it's Case 3 that's "Instantly Focus on objects in the frame"....BUT I've never been clear if that means it is faster to ACQUIRE FOCUS initially than the other preset Cases, or if that only means it "instantly focuses" on new objects that enter the frame during tracking (like a wing or another bird), after initial focus has been achieved (maybe initial focus is the same for all cases, I don't really know!).

Try putting the camera to fastest release vs focus. I know that sounds backwards but you will like it. Also try using the Zone AF, that is the large center square, to me that is the best for BIF and then full auto where I select the AF starting point. I do not even use single point for BIF anymore. I set mine to instant focus when something enters the focus points, try to keep that large square on the birds head if close, if really distance it does not matter unless you are f2.8 of something like that. A couple things for you to try. It may be the lens too, I thought I read somewhere about older lenses but I do not remember now.

Instantly focus in the frame is just that, when something enters into the AF array then that should be the object that the AF picks up on and focuses on. It will not change how fast you acquire focus. The speed of the acquiring focus is more to due with the lens speed which can vary a bit. Why I like case 3 is if I am not focused on the bird in the sky but can at least see the shadow of the bird then it will go right to it in the sky. If you have a very busy background then it could easily jump to the background, then it would be best to set it to stay locked on.

Taken this morning @ 1200mm
