Sony has quite a few cheap but great lenses like the 50mm f1.8, 35mm f1.8, 85mm f2.8 and 16-50mm f2.8.
However aside from the 50mm f1.8 the others aren't available. Also 3rd party lenses are also not available. Unless someone knows what he is getting into its not a good option at all.
The advantage is that you get some really good deals in India. Someone is selling a Tamron 200-500mm lens for 25k, a 30mm f1.4 for 10k and a Tamron 10-24mm for 15k posted just yesterday and no one has even expressed interest ! I am having a very hard time to pass up the Tamron 200-500mm (since optically its better than the Sigma 150-500mm and will have IS thanks to the Sony body stabilization) but I seriously doubt I will find time to do justice to that lens while staying in a concrete jungle like Mumbai.
