Not having autofocus in the camera body means you are limited to the more expensive autofocus lenses unless you are prepared to use manual focus.

That depends where you are in the world

That depends where you are in the world - Amazon are a good choice.

1. You will not be able to auto focus OLD LENSES. 5-10 years old lenses. I don't think you would ever be using old lenses.

2.In Delhi some shop keeper sell it around 27K. Other wise big show room price is between 30-32K.

3. Go and seach. No one will come to chennai to search a shop for you.
