Difference Between Nikon D7000 and D90

Nikon D7000 vs D90

D7000 and D90 are two great DSLRs from Nikon. Nikon is a giant camera making company and its every new launch surely creates ripples in the market. When it recently launched its new DSLR named D7000, many were quick to say that it resembled the already popular D90. Indeed there are many similarities in D90 and D7000 but there are quite a few differences that this article intends to point out.

D90 is indeed a great DSLR, but people were patiently awaiting an up gradation, and with the launch of D7000, their wait is over. It is only natural that D7000 retains all the good features of D90 but adds some new exciting features that make all the difference. Here is a quick comparison of these two great DSLR cameras.

传感器

The most important aspect of any camera is its sensor, and this is where D7000 scores over D90. As compared to D90’s 12.3 MP sensor, D7000 has a higher resolution at 16.2 MP. This is an enhancement that is of particular use to professional photographers when they are cropping images. More mega pixels also means the ability to produce larger prints.

ISO

There is a great difference in ISO settings of the two cameras. Whereas D90 allowed an ISO range of 200-3200, it has been improved to 100-6400 in D7000. Even in extended mode, D7000 has a higher setting at 25600 whereas D90 can go up to only ISO 6400. Higher ISO settings are always important for that all important shot, especially in low lighting conditions, and when you dearly wish to reduce noises to a minimum.

支持SDXC

SDXC are next generation memory cards that have higher capacities and allow faster read and write speeds. They also help in faster transfer of images from the camera on to your computer. While D90 does not recognize SDXC, and can go only as far as SDHC memory cards, D7000 allows the user to make use of SDXC cards. Thus when you talk of storage, D7000 is future safe.

Two slots for memory cards

This is another difference that has significance for enthusiasts and professionals. While D7000 allows for dual memory card slots, D90 has only one slot. This not only means more storage and backup, it also means you can keep RAW files separately from JPEG files. This is of considerable importance if you are shooting HD videos as it means that you can have longer videos without any interruptions which a photographer may experience when he is using D90.

1080p的高清视频

While D90 could record HD videos only in 720p, D7000 allows photographers to make both 720p and 1080p HD videos. If you are shooting videos, this may be of considerable advantage to you and worth an upgrade from D90 to D7000. Again, while D90 allowed for only 5 minutes of shooting HD videos, D7000 allows video capture up to 20 minutes.

Higher burst rates

这是一项对体育摄影师具有重要意义的功能。尽管D90的突发速率为4.5，而D7000的突发率为6fps。这意味着快速移动对象的质量质量更好。
