Is it planned to have the Sigma 19mm f/2.8 and/or Sigma 30mm f/2.8 tested on NEX cameras?

I did a simple test of the 30mm myself by photographing the city skyline at the horizon from corner to corner. The pictures are on my flickr account:

I'm curious - why did you get it ?

I'm curious - why did you get it ? [/quote] I like primes and I want to build a system with the 16, 19, 30 and 50mm. I should get the 19mm on monday. [quote name='Klaus' timestamp='1332535969' post='16956'] Seems to be slightly softer to the left, isn't it ? [/quote] It is very slightly softer on the last 1/4 of the frame, as the published MTF indicates. Would you be interested to measure it?

It is very slightly softer on the last 1/4 of the frame, as the published MTF indicates. [/quote] I meant that the left side looks slightly softer than the right side at max. aperture. It's a bit hard to tell though. [quote name='jerome' timestamp='1332571888' post='16968'] Would you be interested to measure it? [/quote] Sure! But it would be nice if we could do it in late April (If this fits from your side). My queue is very full at the moment.

It seems quite good as well, but I can't take the same pictures of the horizon because of the weather...
