sony NEX 5

[kevincsng]

Hi guys,
Just wondering if you can help me with a decision on a lens for my Sony Nex 5.

Im tossing up between this one

Voigtlander Nokton 40mm F/1.4 SC Black 40 f1.4 Leica M
or

Voigtlander Nokton Classic 35mm F/1.4 SC f1.4 Leica M

There is about $200.00 difference between each lens so I am really not sure which one to get. I currrently just have the NEX 5 Twin Lens kit.
I want a lens which is good for street photograph.

Can anyone shed any light which one they would go for and would I notice a significant difference in quality of photos compared to the standard nex lens?

Thanks for your advice

I'm looking at the same things as well..... any suggestions from others? Or samples?
