The Nikon D3100, VR DX 55-200mm, and Orion 130mm reflectors are all 18-55mm in diameter. It is best to shoot under the sun at 1/2000 ISO with a f/16 lens. Even so, you will have to manually adjust the exposure because all that night sky will fool your cameras light meter.
Nikon D3100 Video Mode: The Bottom Line. Overall, we felt that the Nikon D3100's video mode was a good step in the right direction, as most consumers will want their cameras to be able to focus
Sporting a 24-megapixel sensor, 3.2-inch swiveling touchscreen and compatibility with a huge range of lenses, the Nikon D5600 is the best camera for most people looking for a Nikon DSLR.
This thing is like lightening compared to the D40! I use my cameras for 2 very different purposes, 1. still shots of detailed work for professional use, and 2. action shots of my children playing soccer, baseball, basketball and football for personal use. The D3100 provides a wonderful outcome for both uses.
This lightweight camera is only 1.8 oz, and everything fits in the camera bag easily. It’s the best choice camera to bring along on any journey. Taking photos is easier too because of the ergonomic grip. The Nikon D3100 was designed to enhance your photography experience while being easy to take on the go. The ISO setting on the Nikon D3100 adjusts the camera’s sensitivity to light. At a higher ISO, you can use a faster shutter speed or a smaller aperture (higher f-stop number) because less light is needed to expose the image. The biggest similarity of the two cameras is the outstanding quality of the images that the cameras capture. In normal lighting, using a good lens, the images produced by both the D3100 and D3200, are equal to the Nikon, D4, which is Nikon’s top of the line professional camera. .
