There are three.
Oldest one is f3.8
Then there's the f3.5-4.5
Then, and I assume lowest rated of the three, the newer f4-5.6 (but I don't want to assume my assumption is correct without checking!)
Which is the best of the three in image quality?
A decision re the weight and the speed is obviously my call but I'd like to know the essential quality of the glass re distortions and sharpness.
Thanks.
