Tips to select a Digital Camera
相机的分辨率
再保险solution of the camera is one of the main features a user must look into when buying a camera. This is also known as the megapixel value. The D5100 features a 16.2 megapixel sensor built into it. This camera also has 14 bit A/D conversion. On the other hand, the D3100 has a 14.2 megapixel sensor with 12 bit A/D conversion. The resolution and the performance of the D5100 sensor are better than the D3100.
ISO Performance
ISO value range is also an important feature. The ISO value of the sensor means, how much sensitive the sensor is to a given quantum of light. This feature is very important in night shots and sports and action photography. But increasing the ISO value causes a noise in the photograph. The Nikon D3100 has an ISO sensitivity range of 100 to 3200 ISO with extended settings of 6400 ISO and 12800 ISO. The D5100 goes a step further to create an ISO range of 100 to 6400 ISO with extended settings up to 25600 ISO.
每秒帧
Frames per second rate or more commonly known as the FPS rate is also an important aspect when it comes to sports, wildlife and action photography. FPS rate means the mean number of photos the camera can shoot per second on a certain setting. The D5100 has an impressive frame rate for an entry level DSLR camera. It can go up to 4 frames per second. The D3100, on the other hand, can go up to 3 frames per second. In the sense of speed, D5100 excels D3100.
快门滞后和恢复时间
一旦按下快门释放,DSLR将不会立即拍摄照片。在大多数情况下,按下按钮后,将进行自动聚焦和自动白色平衡。因此,新闻界和实际照片之间存在时间差距。这就是相机的快门滞后。在自动对焦速度和准确性的情况下,D3100和D5100都完全相同,因为它们是使用相同技术构建的。
自动对焦点的数量
Autofocus points or AF points are the points, which are built into the memory of the camera. If priority is given to AF point, camera will use its autofocus ability to focus the lens to the object in the given AF point. Both of these cameras have 11 autofocus points each. But D5100 uses a slightly advanced cross type system, which gives it a bit of a lead over D3100.
High Definition Movie Recording
High definition movies or HD movies correspond to movies having resolution higher than standard definition movies. HD movie modes are 720p and 1080p. 720p has dimensions of 1280×720 pixels, while the 1080p has dimensions of 1920×1080 pixels. Both of these cameras can record movies up to 1080p in a 24 fps speed.
Weight and Dimensions
The Nikon D3100 measures 124 x 96 x 75 mm in dimensions and weighs 505 grams with battery, on the other hand, D5100 measures 128 x 97 x 79 mm, which is slightly larger than the D3100 and it weighs about 560 grams with battery.
Storage Medium and Capacity
在数码单反相机中,内置的内存几乎可以忽略不计。需要外部存储设备来保存图像。这两个相机都能够处理SDXC或更低的单个存储卡。
展示的实时视图和灵活性
实时视图是将LCD用作取景器的能力。这可能很方便,因为LCD清晰地预览了图片的颜色良好。D5100具有3英寸不同的角度LCD,带有实时视图。尼康D3100具有相同的显示屏,但不变角度。
Conclusion
The Nikon D5100 is an improved version of Nikon D3100. The D5100 has better resolution, better AF system, better ISO sensitivity, higher speed and vary angle of the LCD than the D3100. Considering the price, both of these cameras, are worth the money spent on them.
