Just read the manual of the 5D III, 1/250 as fastest time for auto iso is bloody stupid. Still usless for sport and action. Might be of use for weddings but that its. Why are they doing this to us?
Stop arguing whether you need it or don't, no one cares, there are a lot of people who find it useful, if you don't you don't have to use it.
Fact is there are fast moving situations you want to shoot that might change from sunlight to shadow. And if you change ISO values you loose important moments. Sure you can just shoot everything with 6400 or higher to be on the save side. But its just damn convenient to have the camera user lower ISOs and faster times wich results in better quality if the light allows it.
And why not be angry about this feature? For me this would have been the main reason to upgrade from II to III. Because i shoot under those conditions a lot. And i thought they finally did it, then i read the manual and found that ridiculous limit for the shutter speed. As they said the II has Auto ISO i thought i can use it, and now 2 camera generations (7D was in between) later they still haven't figured it out
Using TV doesn't help either because you cant shoot everything with 2.8
And M, makes no sense at all Sure you could set your limit time, but in AV you could get faster if the light allows it. And in M, the camera has to use higher ISOs because 1/800 F4 just doesn't work in bright sunlight with ISO 200, and its not allowed to use faster times in M. So no gain in picture quality there.
Fact the camera is rubbish and useless in my opinion as a MII owner. And yes other people might like, want different features. Thats called freedom of thought.
If you also think this is rubbish, fill out a Canon online contact form and tell them, maybe they will do something about, they activated the F8 autofocus for the 1DX didnt they? Maybe there is still hope.
