A few weeks ago Nikon had globally announced the Z6 and the Z7 mirrorless cameras. Today the company launched the two cameras in India. For Nikon, the Z6 and the Z7 is the beginning of a new chapter as it enters the mirrorless camera market in earnest. Both the Z6 and the Z7 are full-frame mirrorless cameras, hoping to challenge Sony that dominates this market with A series cameras. As such these are also high-end cameras with the Z6 sporting a price tag of Rs 169,950 and the Z7 coming in at Rs 269,950.These prices are for only the body. With kit lens, the cameras are more expensive. The new Nikon cameras also come with a new Z mount, which means Nikon has also launched the Z Mount to F mount adapter, which costs extra. The prices for various Z6 and the Z7 configuration are:– Nikon Z7 body only: Rs 269,950– Nikon Z7 + NIKKOR Z 24-70mm F/4 S + Mount Adapter FTZ Kit: Rs 326,950– Nikon Z7 + NIKKOR Z 24-70mm F/4 S Kit: Rs 314,950– Nikon Z7 + Mount Adapter FTZ Kit: Rs 281,950– Nikon Z6 (body only): Rs 169,950– Nikon Z6 + NIKKOR Z 24-70mm F/4 S + Mount Adapter FTZ Kit: Rs 226,950– Nikon Z6 + NIKKOR Z 24-70mm F/4 S: Rs 214,950– Nikon Z6 + Z6 Mount Adapter FTZ Kit: Rs 181,950In addition to new cameras, Nikon has also launched in India three new S lens, which will natively support Z mount. These lenses are:– NIKKOR Z 24-70mm F/4 S: Rs 78,450advertisement– NIKKOR Z 35mm f/1.8 S: Rs 66,950– Mount Adapter FTZ: Rs 19,950– NIKKOR Z 50mm f/1.8 S: Rs 50,950Nikon is hoping that with its new lenses and the new mount, which is extremely wide, it will be able to compete better with Sony, which is in the full-frame mirrorless market for several years now and has won dedicated fans with the recent A7 Mark 3 and A9 Mark 1. With the new Z cameras and and new lenses, the company also hopes to compete with Canon EOS R, which is also a full-frame mirrorless camera and that will launch in India on September 21.The Nikon Z7 will be available in India from September 27 while the Z6 will come only in November. The Z7 is a high-resolution camera with a 45-megapixel image sensor. The Z6, however, is more regular mainstream camera with a 24-megapixel image sensor.Like other mirrorless cameras in the market, the Z6 and the Z7 are smaller compared to full-frame DSLR cameras. Also, like other mirrorless cameras, come support better video recording features as well as come with components like electronic viewfinder and focus points that spread edge-to-edge on a picture frame.However, compared to the Nikon DSLR cameras like the D850 and the D750 that are tried and tested and are widely acknowledged as some of the best cameras ever made, the Z6 and the Z7 are relatively unknown at the moment. Yet, they debut at a price point that is slightly higher relative to the price of Nikon DSLR cameras. For example, the D750 — which has one of the best auto-focus systems, one of the best image sensors and one of the best ISO performances ever seen in a camera — sells for around Rs 1.1 lakh in the Indian market. That may pose challenge for Nikon.
