Nikon D40 What You Need to Know for Best Performance

Nikon D40 Battery Type & Replacements
The Nikon D40 uses a Nikon EN-EL9 Lithium-Ion & charger included.
The battery can not be charged via USB. This means a battery charger will be necessary. There are third party battery chargers available.
Memory Card Compatibility & Recommendation
The Nikon D40 is compatible with SD/SDHC memory cards.
That means compatible D40 SD cards can have a maximum storage capacity of up to 32GB.
My recommendation is to get a 32GB SD card with UHS-I. These cards will have the fastest transfer speeds, which improves compatibility with newer cameras and other devices.
Nikon F Mount Lens Compatibility
The D40 is compatible with Nikon F mount lenses. This opens up a wide range of lens possibilities. A full range of lenses exists including circular fisheye, ultra wide angle, perspective control, macro, telephoto, mirror, bellows, and all kinds of zooms.
There is a list of the best Nikon D40 lenses that covers lenses for all different types of photography.
The camera has an APS-C “crop” sensor that has been designed to use DX lenses. These lenses are smaller and less expensive than FX lenses, which are designed to be used on full frame cameras.
The D40 can also use full frame, ‘FX’, lenses. However, the downside to these lenses is that they tend to be larger, heavier, and more expensive than DX lenses.
