Actually I do agree that the camera is not important.. It truly is the person behind it.
I just came back from Brighton today after a month, shot some with just an Iphone & they didnt look too bad at all. The camera is just a tool for recording images really, any camera can do that but it is still the person who pushes the shutter at the right moment.
really? try doing a concert or a safari shot with that? if the images is just for a record, perhaps any camera will do. if certain features or aesthetic vision are expected out of these images, suitable camera gear/accessories and suitable (human/equipment) approaches will have to be adapted accordingly. a human being without gear afterall has certain limitations as much as the gear itself has - u can either add a suitable flash for the desired effect, or wait with the model till the sun goes to the right place for your model and background.
and it is not all about the eventual effects or the image. some ppl wants to have certain accessories to aid in the process and to make it easier. if someone's eyesight is not as good, should he try to get a camera with a brighter and larger viewfinder, or should he try to improve his eyesight (and how?). certain things about human beings are bottlenecks, which u may not have faced, but other ppl does, and saying only the photographer matters would not help him, trying to look into what is the bottleneck and what solutions are there on method, approach, gear, and choice of subjects are such a big spectrum. so it wouldn't be just a single thing that is impt.
