Nikon has just announced the launch of the D610 full-frame FX-format DSLR camera. The launch comes one year after Nikon released the D600 and with only minor changes, it looks to be a replacement for last years model. Updates include a new shutter mechanism allowing for faster and quieter continuous shooting and improved white balance settings. The camera still packs 24.3 megapixels, a full frame CMOS sensor, and variable FPS video shooting capabilities. Retailing at $1,999 USD for the body only, the D610 provides some good competition in the very competitive HD-SLR market.
