-Official- 1D MK III AF Thread. Firmware? Hardware Fix Is IN!!!

jr_senator wrote in post #4056483
I'm not a computer expert, but, could the firmware be downloaded from the camera and put up where others can upload it too?

I am afraid not, once it ´s in the camera ... no option on it to do it as far as I know ...

Anyone noticed here the camera focuses better with fill flash and IS lens

It hasn't been mentioned, but I'll bet a bunch of people are running to try it.

actually sort of. I shot a bridal shower 2 weekends ago and had the darndest time with AF...I thought it was me and the low light obstacles...but there was definite softness in the faces that frustrated me to no end...it was an important shoot too (my daughters) and the photos were garbage...(my flash wasn't working at the time). Then last weekend I shot a trash the dress shoot, with fill flash and both IS and non IS lenses...the camera never missed a beat on the shoot. Not once. Now after both those shoots, I deduced from my shots that I had camera shake on some of the lowlight shots and on some it just chose the most contrasty thing to focus on whether it was the intended AF point or not. The second part was what frustrated me (the first part is user error) but then I remembered that even my 5D did that in ultra low light...it's just a camera and does it's best to do what I tell it to but it's not artificial intelligence...SO...my ultimate conclusion: I just chalked it up to a poor setting and unfortunate circumstances (flash not working)...but there was a definite difference in handling under the circumstances I listed.

Too me at least this is normal for most cameras - if your image isn't shaking/moving as much focusing got to be easier ( presuming your handheld ) and if your using fill flash the red grid focusing aid has got to help if your in low light.

Obviously flash pictures in general tend to look sharper, content and colour, but does ponder the question as to why the focus works better, I know the 580ex11 gives a preflash so maybe this info helps the AF in acquiring fist lock on, with out flash the A1 might lock on but not where intended, just a thought

What do you mean by "focuses better" I thought yours worked fine?

Mine does focus fine, you have seen it does, www.cyclingimages.co.u​k just pondering the question "has anyone noticed IT DOES"

I see, the implication was otherwise. Have you shot birds in flight?

I guess the question still remains though. What do you mean by focuses better? Faster? Correctly? More often correctly?

No, probably if i did then I would be moaning about the A1 , as mentioned previous, never use all focus points, didn't work that well on my 1dmk11 so no confidence using it on the mk111, but I would appreciate that it is difficult to track a bird with one active point, maybe a quick burst at 10fps might catch it ??

I have heard it said somewhere that the actual keepers of in focus shoots seems to increase if flash is used, now don't no if its true or not just wondered if any here had experienced this scenario, or if this applies in any cam using flash light as a main or fill in source

Martin

PS did take one [not mk3 mk2]oh dear this is going to disappear

Just curious if you'd tried birds with yours. I'm pretty firmly believing that the type of photography is a factor in how well the AF works (i.e. the size of the targets etc.) . I'm also pretty firmly believing there is a wide range of how prominant the problem is which to me indicates some type of hardware tolerance or assembly tolerance issue that the design did not take into account.

Tell you what KAC if I have time this weekend I will have a go at it, there Kites near where i live if the weather is summat like I will give it a good test as I would be interested to see,
But someone pointed out previously that he was taking shots of horse with not much success, now that seems really bad, a horse, oh dear

Cool. I'm relatively convinced mine pretty badly broken, but Canon has not been able to fix it so far. I still have hope.

Maybe the AF assist lamp on the flash is improving the ability of the camera to see the contrast in what it's trying to focus on? Dunno...just a thought...

Hi All,

Without having to scan through all these pages, does anybody know if 1.1.1 is available? I have had my Mk iii for about a month and put it into action this week shooting badminton. Half way through the first day, i've started getting err 99 messages, and of course the locked mirror.....frustrating​!!!

Love the camera, perfect for indoor fast sports.....just need it to work properly...

Thanks

Mark
