Anyone buying APS-C is taking a punt now.

as I have been predicting for five years, FF costs have now fallen into the APS-C area. So if you build up and extensive range of APS-C lenses because you cannot currently afford FF, you are buying into dying system.

For those who are not cash strapped your options are:

Shoot mostly static objects, size and weight and issue - MFT.

Shoot mostly moving objects, size and weight an issue - APS-C, for now, but you have a problem sunshine.

Size and weight not an issue - FF.
