The myth of the small sidewheel is one of my big pet hates in the world of FT at the present time.
Over the last couple of years it has become increasingly popular to extol the advantages of this piece of apparatus, claiming it offers more accurate range finding and a "snappier" focus.
These claims are 100% untrue, a smaller sidewheel is just that; smaller.
It's neither better nor worse, just a different dimension.
So let's put this untruth to sleep, along with a multitude of other bull talked in FT.
Please feel free to argue the case for advantages, but you're wrong.
