Detailed Analysis of the Nikon D7100 DSLR Camera
The Nikon D7100 is a popular choice among photographers, offering several improvements over its predecessor, the D7000. This DSLR boasts a higher resolution sensor (24.1MP vs 16.2MP on the D7000), better image processing capabilities, and faster autofocus, especially in low-light conditions and when using a teleconverter.
One of the standout features of the D7100 is its 1080p video capability, which can be recorded at up to 60fps in MPEG-4 and H.264 format. It also comes equipped with dual SD card slots, uncompressed HDMI video output, and a 3.2-inch LCD screen.
In terms of underwater photography, the D7100 requires turning off the AF-assist illumination to avoid slow focusing, a crucial aspect for capturing fast-moving underwater subjects. Although the D7000 is still capable underwater, it may lack some autofocus speed and resolution advantages of the D7100.
The D7100's improved sensor resolution and image quality make it a preferred choice for underwater photography, where budget allows. For wide-angle photography, underwater photographers might also consider the Canon 5D Mark III or the Nikon D600 for improved dynamic range.
For portrait photography, an inexpensive 50mm F1.8 lens is a must. For landscape photography, the Nikon 10-24mm or Sigma 10-20mm are recommended for the D7100, depending on budget. For general purpose travel, the 18-135mm kit lens can be used, but the extended reach of the 18-200mm VR is preferred.
The D7100 has a 1.3 crop factor for stills & video, which can be useful for reducing angle of view or increasing reach. For wildlife photography, the 80-400mm VR is a staple, and the 200-400 F4 VR lens is excellent for wildlife with a great bokeh.
For indoor events or street photography, fast F4 or F2.8 zoom lenses in the 16-35, 17-55, or 24-70 range are recommended. The D7100 also features SPOT white balance in live view mode, which can be useful for underwater video.
The D7100 focuses well in night photography with the 18-200mm lens and a sola 800 red light focusing on the subject. It has 51 auto-focus points, an improvement from the 39 on the D7000.
The Nikon D7100 is known for its ultralong battery life, CIPA rated to 950 shots. It shares a fast 1/320s flash sync speed with the D7000, which is beneficial for action shots and underwater strobes.
In summary, the Nikon D7100 offers better image resolution and slightly improved autofocus performance, but careful AF-assist illuminator settings are needed for fast focusing underwater. The D7000 remains a solid, less expensive option with reliable performance but lower resolution and slightly older AF technology.
