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.

David I did find improvement in the haze regard, prior AF would hunt and not lock on, now it seems to lock on much better. The haze is still there but you get usable shots. Here is one which had a bit of heat haze. You can see the haze in the top part of the picture. This is with a 2x also which usually makes that worse.

Excellent, thanks Rob. That worked perfectly. Having seen how your 2x extender works I'm looking to add one to the kit now as it does appear to work much better with the mkiii body than previous versions. Be interesting to see how it performs when combined with the 200-400 f4.
I'm finally getting released to do some bird/wildlife pics this afternoon. Hopefully see how this mkiii behaves, if the wildlife co-operate that is.
Sadly still no motorsports at the minute, although if things continue to progress, there might be the opportunity to do some private test days which is always good fun and gives a bit more scope in terms of getting some much needed practice in.

I seem to have more trouble controlling highlights than I used to with the mk2, Particularly in sunny conditions.
Anyone else finding this?

I am surprised as the literature suggests the new sensor has a higher dynamic range than the predecessor.

Well, I started getting the Error 70 again using the Sony Card. I'm working with the local camera shop where I purchased camera and card. They've gotten Canon and Sony involved. Hopefully we can get a resolution. Is anyone else here having this issue besides Kickflipkid687?

I received my 1DX3 yesterday along with two 128 GB Sony CFExpress cards. Under what conditions do you see the Error 70? I'll try to reproduce it.

Don't 1-series Canons have a setting to bias exposure under the hood, beyond what EC does? Maybe that would need to be tweaked to work like the previous camera. Are your metering settings the same? Is it a picture style difference that you forgot about?

I shoot in RAW and process my images using the Canon DPP software.
I use third party software for image modification, should that be required, but it's not something I customarily perform.

I'm fairly set in my ways so the changes are most likely with the camera as opposed to my workflow.

I find myself musing the effects of the new low pass filter now.

I don't know what "theory" says. In my own experience (66 years old with a bit of shaky hands), camera shake effect is the same whether near or far. Rob mentioned earlier that atmosphere can have an adverse effect. I've seen that many, many times. Here's an example taken with a 1DX2 + 100-400 II (the blurriness is all due to atmosphere). The photo distance is similar to your 400 yards away.

Thank you so much.
That completely replicates the issue I was having. Atmospherics, really? In all my years I never knew.

I too am old and shake a lot.

First outing this afternoon to test the AF of the mkiii since the lockdown was implemented. Unfortunately half the country and their kids headed to the same location so the chance of some decent wildlife was extremely limited. Managed to get access to one of the viewing hides for some relative peace from the hoards and put the partial tracking on, based on the large square in the centre of the frame, and followed a few random birds flying across the lough across my path. Lighting was bright and quite harsh, but I think the AF system held very well considering the contrasty background and choppy waters which would have previously been an issue for the mkii. All handheld shots, with image stabilisation off.
Be interesting to see how well it manages in my normal genre of motorcycle racing and soccer, but thats for another day. Just nice to blow the dust off today even if the subject matter wasn't that exciting.

Glad to see you putting it to some use
