Sony NEX-7 with Sigma 30mm F2.8 EX DN Lens
A friend in Hong Kong “Spike” has posted a review of the Sony NEX-7 with Sigma 30mm F2.8 EX DN Lens. Link; Here’s an excerpt:
To my eyes, F5.6 is pretty sharp there, F8 is okay-ish, and then it starts to drop off till it’s seriously fuzzy at F22.
But all in all, for a lens that costs around US$200, I’d say the overall results are quite impressive.
I’d say for $200.00 its a pretty darn good deal. But I personally wonder if you gain that much with this lens as opposed to just getting the Sony 18-55mm F3.5-5.6 Sure at 30mm you loose a half stop but you have OSS (optical steady shot) to take up that difference. Also this lens doesn’t seem to do anything particularly well? I may be wrong but do you buy this lens for the Bokeh at F2.8 is the color great, does it have zero distortion? Beyond just having prime lenses I am curious what this lens is good for. Then I’ll decide if I’ll part with my $200.00 USD.

Thanks for the link!
In my head, I wasn’t comparing it to the Sony 18-55mm lens. Check this link:

”The Sony E 18-55mm f/3.5-5.6 OSS may perform decently on lower resolution NEX cameras (the 3 and 5 series). However, its capabilities are clearly overstrained on Sony’s 24 megapixel sensor. … it is obvious that this fairly new lens is already outdated – it is just not good enough anymore at 24 megapixels.”
I was thinking of it in relation to Sony’s own 30mm f3.5 lens – so slightly wider aperture at a cheaper price. Also I don’t think that image stabilization is needed on wider angle lenses.
I don’t have that lens but perhaps in a few days if I have the time I’ll do a comparison against the 18-55mm at 30mm, should be interesting, no?
spike, I think that would be a great comparison, and I would love to see it!
It took me time to learn all the comments, but I honestly loved the blog. It proved to be very advantageous to me and I’m positive to all of the followers here!
thanks so much for the comments of support. keep coming back, lots of new stuff being posted!
Good job
The Sigma 30 is sharper all over the frame, has less CA and less distortion than the kit zoom. In fact, in terms of resolution, the Sigma 30 is incredible. See here: http://www.lensrentals.com/blog/2012/04/nex-7-lens-imatest-resolution-comparison
“Sure at 30mm you loose a half stop”
Not true…you loose more than 1 full stop (f/4.5)
you ate right, with the zoom factor!! I’m sorry for the confusion. I stand corrected. Thanks for catching that!
