As we all know, Pentax Q does not support any EVF (Electronic View-Finder) nor there is any I/O (Input/Output) port/interface for mounting such a possible accessory in the future - which is simply not possible for the Q design actually.
So, what's the workaround then? In fact, NEX users have been facing the same problem since Sony never provided/produced an EVF ever even though they do already have a dedicated I/O port on all of their NEX bodies. But clever users have always been able to find out some ways to tackle the problem, see this:-

Brilliant? :-D
Nevertheless, speaking of the Q Vs the NEX, one thing the Q shines over the NEX is that it is equipped with a built-in interval timer, which the NEX doesn't have. Just in the worst case of the NEX-3 and C3, there is even not an Infrared port for controlling the camera so that things have to be carried out purely mechanically. Look at this robotic control, which IMO is just clumsy and funny:-

Nevertheless, it is still a technically feasible workaround. And when one has no choice, it is just better than none! :-o
