Yes, less.  Vignetting issues get easier to avoid.

Think about the cone of light and how the smaller sensor could be affected .

or

Think about an 11x14 camera and lens, then switch the same lens to a Minox
camera body.... 

On an M8, using the front end UV/IR filters, there are issues....but that is
not what you are trying to accomplish.

OTOH, focus plane location is more critical on any Digi-Camera..... but that
gets worse with longer lenses rather than worse with wider lenses.

As Dr. Ted says..... &*%$&^ the techie stuff, go take pictures.....

I'm thinking about getting a 35mm Summilux or Summicron R but also 
thinking about using it on my Sigma, 1.7x crop and/or four thirds, 2.0x 
crop.  My question is, are there added/different problems on smaller 
than FF sensors using wider angle lenses than mounting something like a 
50mm or 90mm lens?
