I find two lenses 28-80 listed in Photodo Pentax lens test as below:
SMC-A 28-80/3.5-4.5 rating 2.1
SMC-F 28-80/3.5-4.5 rating 3.3
Does it mean that SMC-F 28-80 is far better than SMC-A 28-80 as above?
These 2 lenses should be optically identical. 'A' lenses were usually better built than 'F' lenses so the 'A' should score higher. It could be just another mistake they made (like SMC-A 70-200/4 which doesn't exist)? I don't know.
