Hi all. I must stop reading about this camera!!
A couple of questions as I struggle on by with my old mark iii......
For those upgrading from the mark iii, has anyone noticed the larger files having a significant effect on computer performance, processing speed?
AV mode, bounced speedlite, auto ISO; the mark iii defaulted to 400, will the mark 4 select between 400 to 1600?
I really enjoyed struggling with my old 5D3 I thought I would but I was surprised there was not a huge noticeable difference. The crop power you gain is well worth it.
I have shot a lot of flash with all my bodies but never used Auto ISO and especially for flash but that is just me. It is not a function of the body but the flash system itself. For the pre-flash to work correctly the system needs to know 3 settings - aperture, shutter speed and ISO so this is why it defaults to 400. Not sure if they made any changes to the 5D4 but I can't see it and I think this was talked about somewhere else.
I have a theory as to why 400. When I took lighting courses the standard bases settings were 1/160, f8 and ISO 400. I think Canon just adopted that. I think the same may apply to why when you turn or raise the flash head the zoom defaults to 50mm. Back in the day when you purchased an SLR the standard lens was 50mm. So just an old base value. I could be wrong but I have not found any other reason for it.
