Hi, I would like to make a suggestion to Canon on the 5D3 camera, with regard to the minimum shutter speed for auto ISO. Currently I find that most of the selectable shutter speeds are on the low side (mostly below 1/125), and this may not be useful for handheld photography, or for fast moving subjects. I would like to suggest the following:
- More minimum shutter speed settings faster than 1/125 including in-between speeds e.g. 1/160 (between 1/125 and 1/250)
- Automatic shutter speed based on a multiple of lens focal length e.g. 2x lens focal length (for both prime and zoom lenses)
I hope that Canon can come up with an updated firmware that does this. Thanks.
Good idea, you can add it to the thread "Firmware Update Wishlist", and "Canon dSLR Wish List?" because a proper, configurable, flexible auto ISO is much needed and would beneficiate all cameras, not only 5D3.
I am not sure what Magic Lantern can give you on that issue, but you can take a look at their page.
Now, as a short term solution, on 1D4 I have put the cfns for 'shutter speed range' and 'iso speed range' in MyMenu, and when I need I change the max ISO (usually 1600) and a min shutter seepd (depends on lens and subject) on the fly. Not very practical (many button push needed), but it works.
I hope that helps
