I am not a fan of these super zooms.
Why?
Not because the glass is bad, but because the sensor size is too small.
Due to a very problematic thing called physics, if you have a very long range zoom on a large sensor(even APS-C), your lens size goes for a toss.
So with a big sensor a 20x zoom will rival a agni missile in size.
As you reduce sensor size, you can have smaller lenses.
for example till about 6MP Fuji had this big sensor which was amazing. But this meant they could not offer 15x zooms etc.,
With their newer sensor which is 8MP or 10MP, they offer big zooms, but the image quality has gone for a toss.
