Anyone have any opinions on the Sigma 19mm and 30mm primes?

I was after a prime of between 35 and 40mm for the street.

The three lenses I looked at was the Olympus 17mm, Sigma 19mm and Pany 20mm. The Pany 25 and sigma 30mm were a little long for me.

I went for the Sigma 19mm and can`t fault it, its boot up is a little slow but its cheap and nice and sharp.

The lens also comes with a hood and zip up bag.
