I wonder about the future of rangefinder and SLR cameras.
The accuracy of rangefinder focus is adequate for normal and wide angle lenses, but longer focal lengths with large apertures give even well adjusted rangefinders a problem. I say “well adjusted” because the tolerances of lens cams and rangefinder mechanisms is such that level of focusing accuracy can vary with different lens and body combinations. For a lot of us, Norm Goldberg used to zero the tolerances to the degree measurable. I’m told when Norm was passing some of his skills on to his son Don some of my cameras became part of the lesson plan. In any case, having a technician like Don Goldberg check and correct the focusing accuracy of rangefinder lens/body combinations is a wise move, but the rangefinder will always have its limits.
Ditto the SLR because, like the rangefinder, it is not measuring focus at the film or sensor plane. Actually, using live view on a DSLR you are using the sensor to focus. But that is such a stepped and slow method that it isn’t suitable for a lot of photography and few folks use it.
Enter the mirrorless digital. The majority of current mirrorless cameras provide very accurate autofocus of the image on the sensor’s surface or accurate magnified manual focus. And they eliminate the rangefinder and mirror mechanisms, two expensive components that camera manufacturers are probably happy to dispense with.
So, once again, how long will rangefinders and reflexes be around? Face it, the family camera for a lot of folks is their phone. I think I see fewer simple, low priced digital “family” cameras and more versatile, high image quality (and expensive) cameras - cameras that let a company stay profitable even if they sell fewer cameras. And the great, great majority of those cameras are mirrorless.
What do you thing the future is for cameras - but, more important, what cameras do you think you will be using in the future - and why?
