<< Gary, you know long time ago my opinion about your tests, but you know too
 my way of thinking concerning the differents focal lehghts on your tests on
 a zoom lens. If we have the Zuiko fixed lenses focal lenghts as
 fundamentals, I think a zoom must be tested at these focal lenghts and at
 the beginnin and end. This thing allow to compare and choose.

Let me step in and defend Gary here.  And as you've mentioned, we all thank 
Gary for his fine efforts. I've done some of my own informal testing and it's 
a lot of time, work and expense. You really don't need to compare a zoom to 
fixed focal length Zuikos because you first want to know how the entire zoom 
performs from maximum wide to maximum zoom. As to any specific focal lengths 
in between the zoom range, you can extrapolate. As such you can compare 150mm 
to 135mm or 250mm to 200 or 300mm because the resolution and contrast aren't 
going to change that much. The focal length doesn't matter because, I think, 
Gary has compensated so that the image size on the slide is the same for 
every test.
