Well, it's both :-) The CoC size change is a side effect of the applied program shift. I'm not sure if Canon allowed this intentionally in their lesser (non pro) bodies, although it is a useful thing. > > It would be cool if they had a DEP mode CoC selection as a custom function. > It would be easy to make the change in firmware but I doubt many > photographers would make use of this option.

Yes, this is another workaround for the "problem". For my kind of pictures, DEP mode is not required anyway. Well, to be honest, I don't know if DEP mode is *required* for any type of shooting. Generations of photographers could do without it :-) What kind of annoys me is, that it just doesn't work to it's full potential the way it is implemented in the pro bodies. Personally, I use either hyperfocal focusing or even focus on infinity and stop down a little more for most of my pictures. And for most of the rest, some action type photos (occasional racing shots), there's certainly not enough time to use DEP mode anyway. ;-) And for the small rest of my shooting, if I use DEP mode, the workarounds like choosing the AF points as to expand the zone of focus or simply changing modes first and then do whatever I want with the aperture value is sufficient. It would be easier if it (DEP) was implemented like e.g. on my EOS 5 and 100, though. Hehe, if Canon had implemented DEP mode on all models like on the 1N, maybe noone would ever had complained about it. But to *show* they can do better and then not to do so intentionally(?) means asking for trouble and critique. ;-) Thomas Bantel * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
