Lens suggestion for D3100

[visurao4all]

Hi guys,

I am very new to his hobby of photography
Started with a Nikon D3100

I am looking out for 2 different lenses
1. for out door photography (basically to take pics of some distant objects)
2. for taking extreme close-ups (taking pics of flowers, insects, etc...)

Can you pls suggest, if these are gud options?

For 1.

Nikon High Powerzoom AF Zoom 70 300mm F/4 5.6G | Buy camera | Indiaplaza
Is this compatible with Nikon cameras?

Nikkor 55-200 VR Lense - Hyderabad: Camera Accessories in Hyderabad at Quikr Hyderabad

sigma 70-300mm f4 5.6DGOS
filter size 62
Is this compatible with Nikon cameras? I heard its a lens with VR as well

Which of those 3 mentioned above is good for outdoor photography?

For 2.
Nikkor 50mm 1.8D AF Lens - Hyderabad: Camera Accessories in Hyderabad at Quikr Hyderabad

If they are nt gud, pls suggest a better lens

Thanks a lot in advance!

Regards,
