Nikon continues to hold strong in the DSLR camera market with 39.1% market share (compared to Canon's 54.7% share). Nikon has benefited greatly by using well-regarded Sony sensors in its cameras.
Sony sensor technology is so great that company like Nikon who capture 39.1% of the DSLR market depends upon Sony sensors. I am not sure if Nikon heading towards bankruptcy but looking at the current decline in sales and loss of profits every year and limiting budget for R & D let's see how long they may sustain. I suggested Sony because if Nikon is depending on Sony sensor technology then why not just buy the Sony.
Nikon benefits from Sony's R&D by implementing their sensors in Nikon cameras. However, Nikon has done very little in terms of inventing new features on the cameras themselves. They have been slow to implement connectivity features as well as making any effort to reduce the size and weight of their gear. Sony is dumping billions of dollars into research and development of image sensors, which seems to be paying dividends. That also translates into camera sales, because they often prevent other companies from using their imaging sensors until Sony has used the sensor for 6 months in their own cameras. Your choice of camera is obviously a personal decision. But I hope that this background information can help you to make a more informed decision with your dollars.
