Marco Carmassi (Facebook | 500px) shares his experience and photographs from his trip to Rajasthan:
Two days before I was to begin a trip to Rajasthan I decided to replace my Nikon D800 with the new D810.
With my D800 I had some doubts about the speed of autofocus, because it is one thing to use it in static situations such as a studio or a landscape and another to use it in dynamic conditions such as street photography where the AF accuracy is very important.
