    A couple of questions:
    
    Assuming a digital camera, does it have a full size (24MM x 36mm) array,
    or a smaller chip that would effectively reduce the field of view and
    cause the lens to approximate a 280mm lens in 35mm format?
    
    What are you using for a filter?
    
    Thanks
    
    Bill B.
