Extend your budget by 2.3k and grab the Lumia 720. With f/1.9, it has the second largest aperture among all the smartphones next to Lenovo K900 which has f/1.8 and costs 29k. Even the Lumia 920 has a f/2.0. Im a photographer myself so I can tell :)
Btw do you know you can even charge the 720...

If you'r looking to buy LG Optimus L9 online it is cheaper on Amazon India than on Flipkart. Be sure to considerNokia Lumia 620 too.
Go for Nokia Lumia 820 - Flipkart.com. Its 1GB ram wont disappoint you. Plus, Nokia has really worked on camera quality of Lumia series and this one comes with Carl Zeiss lens. Personally I really love the bold design of this phone.
You should go for Samsung NP550P5C @ ₹52,500 - Its got the best of all worlds.
A great display of 1600x900 pixels, SUPERB graphics from Nvidia (650M 2gb - best in class), supercharged 1600Mhz 8 GB Ram, a terabyte of storage and yes WOOFERS !!
Buy HDD from local shops, they are cheaper locally. You can grab a 500gb from Seagate for around ₹2800.
To cut costs you can go for AMD A4-5300 for ₹3200 and MSI FM2 for ₹3500. This saves you ₹2000.
Also you can opt for a cheaper GPU like ZOTAC NVIDIA GT 630 for ₹4250 or Sapphire...
