My wife enjoys digital photography but neither of us have too much of a clue about what kit to get. She started off with the Nikon D5100 and standard 8-55mm VR Lens kit and has since accumulated:
Macro: Sigma 105mm f/2.8 EX DG OS HSM
Long range: Nikon AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR Lens
Wide angle: Sigma 10-20mm f3.5 EX DC HSM
Her main uses are family/portrait shots and landscapes. Recently she's been complaining that the standard kit lens images aren't as sharp. Although we're not sure if this is 'as sharp as they used to be' or 'as sharp as the newer lenses'.
So we're looking at getting either a new mid range lens to go on the existing camera or a new body and lens. Any thoughts / suggestion much appreciated.
