I agree. However, while we do not have control over what manufacturers do, we do have control over what we do.
Ask yourself how much better your photographs will be if you get the latest camera model, whatever that might be, when compared to what your current camera gives you.
Alain,
I stopped using 1D series cameras because of the cycle of upgrades. Nikon and Canon lenses are superb and great classic and worthy investments. A lens bought 6 years ago will be good for as long as the lens mount doesn't change. However, the camera body is way different. They're delivered with regular techno-creep, hyped with razzmatazz, as imaging Nirvana! In reality they extort a never-ending levy on photographers' wallets. Photographer's websites freely promote this crap! We're guilty too!
My own belief is that
most photographers could do very well for most everything with the Canon Rebel, or a Nikon/Pentax/ Sony equivalent, any of them, and a 50 1.8 or 1.4, period. With a an f 2.8 telephoto lens, that can cover sports and with the 17-40 zoom, landscape and interiors.
I happen to shoot wide detail-rich scenes and groups of 120 people or more. So I decided several years ago to just use the mid-level full-frame 5D DSLR. The 5D, in practice did a fair job but the 5DII does work better with the extra detail-defining pixels and low light capability. Would I like even more DR, detail and focus accuracy? Of course. However, the limitations on my photography are now few and can almost always be circumvented.
So what if I miss the focus? I'll get it next time by focusing on an edge at the same lens to subject distance. The $4000 needed to make sure
every shot works, simply does not matter for most competent photographers. After all, we can see the result on the LCD. Unless it's a "game changing" never to be repeated moment, in Pro sports or the like, there are so many subsequent new exciting peaks to capture.
As you say, Alain, we should be more resourceful! So let's concentrate on audience, needs, ideas, approach, mind-set, imagination, design, perspective, point of view and composition and protect ourselves from this constant taxation based on seductive tecno-creep!
