Re: [Digital BW] Re: Lenses reviews

2003-10-04 by Truman Prevatt

There are many ways to review a lens. The best way is to use a 
calibrated test fixture that will measure the performance of the lens 
vs. the theatrical performance.  No real lens will perform to 
theoretical and even the best zoom lenses are a compromise from a fixed 
focal length.

I personally take all "subjective" evaluations with a grain of salt 
since you will find that some people find some types of performance 
degradation "pleasing to the eye."

As far as I am concerned on a lens give me the specs so I can see how 
close the design is to theoretical and give me the test numbers that 
determines how well the lens achieves the spec and I am happy. If you 
start with a lens that gives the most faithful reproduction on the back 
side as what is on the front side, then that is the best lens. Things 
that are pleasing to one eye are not pleasing to the next eye.
