91 My sp are battery doesn’t last as long
Rechargeable lithium-ion batteries are expensive, so it’s tempting to buy a third-party copy to save cash. Some are perfectly good, but cost almost as much as the real Nikon item. Others are cheaper, but the makers have cut corners with the components so they just don’t have the same capacity.
92 My SD card won’t click in any more
Check for damage to the fine plastic mouldings around the contact strips at the end. Some of these can snap off, and this can stop the card clicking into place – you can insert it fully but it springs out again. There’s nothing you can do to fix it. It may still work in another camera as some are more sensitive to this than others.
93 Mymemory card has extra folders
This happens when you use the same card in different cameras. Each camera creates its own folder and can’t see the other ones. Then you view the card on your PC, see all the folders and realise that’s where all the space went! Don’t just delete all the photos on the camera, format the card between uses.
94 The aperture changes when I zoom
That’s because most zooms have maximum apertures that vary throughout the zoom range. Let’s say you set an aperture of f/3.5 on your kit lens at its widest zoom setting. When you zoom in this will change to f/5.6 because that’s the maximum aperture at full zoom. When you zoom out it will revert to f/3.5.
95 My filters rotate when I focus
This is annoying when you’re using graduated or polarising filters, which need to be rotated to a precise position. It happens because cheaper lenses (including the Nikon 18-55mm kit lens) use a focus mechanism which rotates the front lens element, which is what the filter mount screws into. You need a different lens!
