Earlier I used two lens for my Nikon D3100, one which is the kit lens of 18-55 mm and another Nikon 55-200 mm. I sold my 55-200 mm lens and bought one Sigma 18-200. What I found next that my photos on my new lens has lost resolution of nearly 25% of what I would earlier used to have on my earlier two lenses. I suspect it is the obvious result of compromises I should be prepared to accept on a super zoom lens.Is there any way I can solve this ?
