SEL50f18 and Nex-5N
Today Sony USA store delivered my SEL35 in one day! I also have the SEL50, but not the Sigma 30, so for me it was much needed especially for video with OSS. Expensive, Yes! but it will be my primary on camera lens for sure. I have been using a Nikon 28mm f2.8 occasionally, but mostly the monster SEL18200 on my NEX 5N. If you love your SEL50, then the SEL30 is a must.
