|comment:||I picked this lens up for $80 with a Sony DT 16-50mm f2,8. Sharpness is fairly good at f/4, improves a lot at f/6.3.|
The weight isn't as bad as some reviews suggest, it is lighter than the Sigma 50-500mm f4-6.3 and around the same weight as the Sony 16-50mm f2.8. The weight distribution is skewed towards the front however especially at 210mm which is more noticeable than the overall weight of the lens.
AF is a little slow especially in low light, I mostly prefer to use manual focus with this lens. If you are fortunate enough to have a body with focus peaking this makes MF less painful and also allows you to see the DOF easily.
My copy is a little soft around the edges at 210mm f/4 but this improves greatly at f/6.3. It does suffer badly from chromatic aberration in high contrast conditions compared to modern lenses with better coatings. You can remove this to some extent in post but it's difficult to get it all. This doesn't really improve significantly on my copy until around f/9
