Third party lens for Sony Nex3

I'm looking for a Lens for my nex 3 since a while,

basically i'm student and a photohobbiest.

i had bought this camera because of its speed and picture quality and ease to use (Can't understand those High tech DSLRs)

i just love the way it work,
but now i want to upgrade my lens from standard 18-55mm to 55-200 or else… (Basically high zoom range)

and a Prime Lens ( Future plans {approax 6-7 months later} )

problem is i can't afford the sony E mount lenses which is like 799$ (i'm just a Regular teenager with limited Money Source)
i want to buy third party lens (Whatever Nikon, canon, sigma or tamron )

i know i have to buy a specific adapter for a particular lens brand.

Please Suggest me a Good Combination of Adapter and lense that would

1) Support my Camera with no compromising of its working (Speed, Auto Focus, picture quality and all those techincal things from which i'm not familiar with)
2) Cheap but no compromising with quality (i.e. Durable)
3) support my future upgradation as well
4) and that Won't Waste my one year's Saving, :)
5) Should be available in INDIA or Atleast Suggest the name

i had searched alot, Read Lots of Reviews,
completely worthless.
i would really appreciate and thankful if you suggest me with your personal experience (Can't take Chance With Experiments or can't change the lens atleast for two years, if Something goes wrong)

Nikon and Canon aren't third-party.

That's the problem when following a path not well trodden. You'll have to come by with whatever is thrown at you. Not much to select from. You should have thought very well about that when you bought into the NEX system.

When using adapters, expect zero compatibility except for the tight fit. Even that may not be perfect. The word adapter is compromising by itself. Don't expect the best quality. Adapters and third-party brands do not have full compatibility with the host system so forget about future upgrades. You are doing this because you don't have enough money to stick to your camera's brand. Deal with and suffer in silence or sell and move to another brand/system.

Zeiss, Cosina, Sigma and Tamron all have the E mount lenses in development.

There are adapters available to adapt just about any lens ever made to your Sony NEX-3 but you can forget about having auto focus or much else in the way of automation. You'd be wise to wait until the third party manufacturers release their E mount lenses.
