If you computer has a card-reader, use that. If it doesn't, buy a USB card reader (ridiculously cheap from wherever you bought your SD cards).

Sorry, but I HAVE to ask this - there's an SD card in your camera, isn't there? Many DSLRs can shoot without one, but they have no internal storage, thus; no card = no photos.

I'm glad to hear things like this…

I buy cameras for one simple thing… To record moments.

'Autofocus', 'Wi-Fi', GPS even 'touchscreen' technology… I don't need it in a camera… Cameras are for taking pictures… Leave the fancy gimmicky stuff out… If it's too much trouble for you to take the SD card out of your camera and slide it into your computer… God help us…

I reckon all these technological advances are killing photography… In 40 years of using cameras i've never had a camera die on me… And the camera that is 'claimed' to be the best APS C sensor option out there died after only 3 months in my experienced hands… That is absolutely shocking… And yes it was a Nikon.
