For that I use this example:

It's a f3.5 at 103mm low light picture, taken with a APS-C camera, the K5.

When I use now my K1 for that, my lens could still capture the same picture, now @ 154.5mm,

On K1, you can still keep fl at 103 mm, aperture at 3.5 and crop. That will be the similar

because it's a 80-200mm and FF lens. For to reach the same DOF like in the picture above (and it's DOF is already very thin) I had to close the aperture about one stop more, when I would use the K1.

Look at this the other way. If you take a photo with K1 @ f3.5, you will need an aperture of maybe f2.4 on apsc and such a lens would be very expensive!

So a FF will give u what you want in crop mode, but not the other way.
