Suggest good camera moible for Rs. 15000-20000 budget

I am planning to upgrade my phone, now I need a phone which comes with a very good camera. So my main priority is to have a very good camera, rest of the features are secondary. But good battery life is must , because do not want to have a phone without battery when I am traveling, so camera and all will go useless and what is its use then.

Should be good enough to open my office documents and specially PDF files. Other than that I think, not very large screen phone.

and as said, my budget is Rs. 15000 - 20000 only , not more than that and also I want to keep it for next 2 years atleast.

You can try samsung grand 2, a good phone and now its well under Rs. 20000 . Other I can think is of Nokia Lumis 730 with its wide angle lens. Other than that, there are many from Sony, LG but none have camera which is really good.

You can go for Windows Phone in this range for good camera and phone too.
