    People using DSLRs with crop sensors are already shitting their pants due to focal length multiplication. Seeing how small the iPhone sensor is, what will it turn a 35mm lens into? A tele?!

    I wasn't aware there was any autofocusing going on inside cell phone cameras? I thought they simply used their incredibly small aperture and corresponding large f ratio to get a really deep field. Consequently the optical system is very slow, leading to their abysmal low light performance.

    Eliminating the mirror, replacing it with an electronic viewfinder has been common in non-removable lens "bridge" cameras for almost a decade. Its all done in the name of cost cutting as its expensive to construct and align a mirror/pentaprism system; a similar move has occurred with compact cameras, where the optical viewfinder has almost completely vanished and users bob about like Meerkats with their little snappers at arms length, trying to compose a picture in bright sunlight. Opttical viewfinders that compensate for focal length are not compatible with cheap digicameras!

    One of the good things with a pure optical path and manual focus is that you can compose images through the viewfinder without having to switch the camera on. If you have a more considered approach to your photography, then this extends battery life. Another is that looking at a scene through a pure digital system isolates your preception of tonal values and true luminance as what you see is already being processed by the intervening electronics. With analogue optics, what you see is what you get!

    As far as this HD-video fad goes, its ok when you're using a bridge camera with a crappy 2.7" sensor, but if you're using a high-end full frame sensor Canon like the 7D or 1D Mk IV, then whats wrong with mirror lock-up? Shooting with such a system, you're either going to be tethered or using the rear screen whilst the camera is mounted on a tripod. It'd be unusual if you were using the viewfinder!

Money is the root of all evil, and man needs roots.
