None to speak of

optical stabilisation made in japan the weight helps to keep image steady

none worth a mention

Quick focusing. Sturdy build

Rather heavy

Good value, good photos.Will give some more expensive lenses a run for their money.

Gets heavy after a while when shooting handheld. use a tripod or monopod .

heavy but get used to it Not very good in dark weather have to put the ISO up

Very well engineered-fits camera body easily. Weight well balanced by the tripod plate. Focus readout dial very useful. Optical stabilisation selection good.
