Hi,
Just thought I would share this news with you. Sony haven't made a big deal about it, but I happened to see it on their website.

What are your thoughts on this lens?

While they have announced it earlier, I'm guessing they don't want to make too much noise about it until you can actually buy it.

If I had a NEX, I think I'd be very much interested in this lens.

Yea, I agree. They say it will be available in shops in September, so not long after the NEX-C3. No word on pricing though.

I think it should come in around the same or less than the alpha 30mm f/2.8 macro in the long term.

I think there are some major flaws with this lens.
Firstly, it's f3.5 - that is far too slow for a macro lens of this caliber.
Second, 30mm is too wide for macro, as you would have to be really close to your subject; especially as the NEX cameras use APS-C sized sensors.
It should be about 60mm at least for a decent macro lens.

Overall, they are not flaws. They are design choices.

f/3.5 is not an issue for macro photography. Normally you would have to stop down to get usable depth of field. A big reason most SLR macro lenses are f/2.8 is to allow the phase AF to keep working at full magnification. Contrast AF of NEX doesn't have the same limit and can work at higher effective apertures. If f/3.5 makes the lens smaller or cheaper, I think that is a positive.

As for the angle, it may not be to everyone's tastes, nor suit every situation, but it still is a macro. I want a wide angle macro myself for the different perspective it offers compared to longer focal length macro lenses. It doesn't replace them wholesale, but supplements them. A shorter focal length at this time means the lens can be smaller. I'd guess longer ones will appear in time.
