You have it backwards, unfortunently. With the Nikon D1 it is like you
have a teleconverter, as it's smaller sensor is only half the area of a
35mm frame. So a 50mm lens on the D1 gives the same feild of view as a
100mm lens on a standard 35mm camera. This is one of the huge
disadvantages to the D1, basically no wide angles. A 28mm lens on the D1
is the same as a 55mm normal lens on a 35mm camera. That's why Nikon has
recently released some hidiously expensive superwides recently (my theory).
Throwing a 2x converter in the mix would give you a 200mm field of view
from a 50mm lens fo 35mm, plus image quality would not be too great as most
of the lens's resolving power would be wasted.
An interesting solution would be a totally new SLR system, based around the
smaller sensor. It would be like the Pentax 110 SLRs, by doing this you
save on costs with smaller, easier to make lenses, plus you'd have wide
angle lenses as you wouldn't be adapting lenses made for a larger format to
the smaller sensor. But I'm glad Pentax stuck with the K-mount and a
24x36mm sensor.
