The actual saying is:
Amateurs talk about gear,Professionals talk about money and masters talk about light" - but your point is well taken
Paul Guba: You know I have been taking pictures for 25 years and have yet to feel the need for 6 digit ISO. Perhaps when I get paid to photo a coal mine. Call me a minority but I would actually like lower ISO, like 32 or 16 I would find it quite useful in studio and with landscapes. That said I shoot nikon and canon and both are fine tools and I don't really give one the edge over the other. I don't have much need for video but it seems that is the biggest thing Canon is offering. Much of the changes are to increase video performance so they must see that as important.
Its not about the camera. Go take pictures.
I totally agree - a genuine lower Iso is of far more use than six digit ISO - unless you are operating a speed camera or for surveillance where iq is not required.This is what canon say it is for!!
