sanjaykool: wrong .....know basics dear reviewer Light gathering by a lens does not depend on diameter of objective lens but inscident angle I.e. Cone from subject being photographed area being photographed reflected light enters lens.

My objection is to say it is 600 mm f 8 equivalent lens actually it gathers light from area what 600 f4 of FF system lens would gather and while doing so it can set widest opening aperture to f4
