|Nikon adopted the SD platform a while ago, including the SDHC memory card, to serve as storage medium for entry-level digital SLR cameras. As for the Nikon D300 and higher, Nikon prefers to use CompactFlash for now. Moreover, the Nikon D90 is the world's first DSLR officially supporting the SanDisk enhanced maximum SDHC speed, the 30MB/sec. SDHC is currently available with 32GB storage which suffices for a DSLR as the D90 to shoot a large amount of pictures.|
|Nikon D90 a fast DSLR camera
The Nikon D90 responses extremely swift, activating and deactivating is so quick that it is hard to capture the precise time it takes, we stick to around 0.35 second before you can take the first picture after activating the camera. This is a speed completely satisfying for the target group of this camera. Also switching from capture to play is fast, a feature that lets you work effortlessly in practice. The Nikon D90 also shows a neat performance when it comes to focusing and is certainly equipped to tackle the speedy work. The specified frame speed of 4.5 frames per second is reached without a problem. The buffer is large enough to store some twenty high resolution/quality JPEG pictures before it has to be emptied.
CompactFlash & SDHC memory card support
All in all, the Nikon D90 responses extremely quickly to all actions. One exception is Live View mode, which has a different way of focusing, which unfortunately comes with a clear delay in focusing. The resolution of 12 Megapixels, the presence of Nikon's NEF format (RAW) and the possibility of shooting in a combination of NEF/JPEG make the files grow to a maximum of 23MB per picture. This is huge and it is therefore wise to go for a storage capacity of at least 4GB, and preferably higher.
Considering 4BG of storage capacity:
4288x2848 pixels - NEF (RAW) - 10.8MB - 133 pictures - 9 pictures buffer
4288x2848 - NEF+JPEG (Fine) - L - 16.9MB - 89 pics - 7 pics buffer
4288x2848 - NEF+JPEG (Fine) - M - 14.4MB - 104 pics - 7 pics buffer
4288x2848 - NEF+JPEG (Fine) - S - 12.4MB - 118 pics - 7 pics buffer
3216x2136 - NEF+JPEG (Fine) - L - 13.9MB - 107 pics - 7 pics buffer
3216x2136 - NEF+JPEG (Fine) - M - 12.6MB - 116 pics - 7 pics buffer
3216x2136 - NEF+JPEG (Fine) - S - 11.6MB - 124 pics - 7 pics buffer
2144x1424 - NEF+JPEG (Fine) - L - 12.3MB - 118 pics - 7 pics buffer
2144x1424 - NEF+JPEG (Fine) - M - 11.7MB - 123 pics - 7 pics buffer
2144x1424 - NEF+JPEG (Fine) - S - 11.2MB - 128 pics - 7 pics buffer
4288x2848 - JPEG (Fine) - L - 6.0MB - 271 pics - 25 pics buffer
4288x2848 - JPEG (Fine) - L - 3.4MB - 480 pics - 100 pics buffer
4288x2848 - JPEG (Fine) - L - 1.6MB - 1000 pics - 100 pics buffer
3216x2136 - JPEG (Fine) - L - 3.0MB - 539 pics - 100 pics buffer
3216x2136 - JPEG (Fine) - L - 1.7MB - 931 pics - 100 pics buffer
3216x2136 - JPEG (Fine) - L - 0.8MB - 2000 pics - 100 pics buffer
2144x1424 - JPEG (Fine) - L - 1.5MB - 1000 pics - 100 pics buffer
2144x1424 - JPEG (Fine) - L - 0.9MB - 1800 pics - 100 pics buffer
2144x1424 - JPEG (Fine) - L - 0.4MB - 3800 pics - 100 pics buffer
Nikon D90 includes a USB 2.0 Hi-Speed port
The Nikon D90 digital SLR features a fast USB 2.0 Hi-Speed port at which high resolution files and in this case, also captured videos (maximum of 2GB in size) can be transferred to a notebook or desktop computer. Although the Nikon D90 is able to transfer these files with high speed through the interface, personally I prefer a fast (FireWire) card reader. I find it the ideal accessory that lets you keep on working with the camera and spares you the fiddling with a separate cable that has to be connected from the camera to an external device.
Nikon EN-EL3e Lithium Ion battery
The EN-EL3e Lithium-Ion battery is the energy source for the Nikon D90. The standard included battery charger takes approximately two hours and fifteen minutes to fully charge this battery. According to standardized CIPA measurements, a fully loaded battery will deliver around 850 pictures, however, in practice you will not reach this number while none of us shoot under controlled laboratory conditions. Unfortunately, there was no indication of the energy use with continuous Live View. From experience however, we know that the amount of pictures might drop considerably.
