Question: I'm considering getting the Sigma 30mm f/2.8 DN. Is it worth paying $200 more for this lens instead, for lower f-stop and OSS?
Document: If this was priced at around $150-200 then it would be a 5 star, but at $450, I do not think is worth the money. Save your cash and continue to use the kit lens or try the SIGMA 30mm, I have not yet tried the Sigma, but it has good reviews.
This lens is on my NEX-7 most of the time now.Only problems are some longitudinal chromatic aberration when shooting wide open in bright light -- this is not fixed by the internal CA compensation, but can be reduced or eliminated in post-processing by DxO Optics or PhotoNinja quite readily. Really, this is minor overall -- usually outdoors you can afford to stop down a little and it goes away. Also the narrow depth of field at f/1.8 takes some getting used to.
I'll admit that I don't have much experience with buying or using photo equipment as this is a new thing I'm starting to get into, but spending the $450 for this bad boy was well worth it for the kind images I'm getting with it on my NEX-6. Yeah, it might be a bit more expensive than a lens of this quality on a regular D-SLR body, but that's not what I'm using so I'm willing to spend the extra.
Being a small lens, the E 35/1.8 is an excellent walk around lens on any E-mount body (especially with 20mm f/2.8 pancake in the pocket for wider scenes).
EDIT #2: I have gotten ahold of and thoroughly tested the new Zeiss Touit 32mm f/1.8, with a review both here on Amazon and my website. Though the below review still stands, the Zeiss is overall an optically better lens.
It's simple. In nearly every shooting situation that calls for the 50mm field-of-view, this 35mm f/1.8 delivers. Low-light? OSS. Subject separation? f/1.8 Sharp landscapes? Shoot at f/5.6. Traveling? It's a compact kit!Ignore the naysayers griping about how it's not compatible with the NEX5r/6's PDAF yet, or that it's "just as good" as the kit lens at 35mm.
This is a nice lens, for a long time I was thinking about getting a fixed aperture lens like this. It has a nice depth of field on my APS-C Cropped sensor. I'm generally happy with it. It does give a little bit of chromatic aberration which is fixable in Photoshop. This might not be a high-end professional lens in comparison with other thousand dollar fast lenses, but it does a good job for someone who is doing photography for fun rather than profession.
Pros:Image resolution and contrast are very high from f/2.2 and closer. Exactly how a prime lens should be. Wide open quality is solid and very usable.Bokeh is nice, but not superb. The rounded shaped aperture blades is an advantage when using apertures in f/2-f4 range.The autofocus is fast with the new phase detection AF mode of the NEX6 and 5R. Almost as fast as in DSLR, except in low light.
The lens appears to be quite sharp corner to corner, and very good wide open. The lens feels great without feeling heavy. Excellent job Sony. IMO, the lens is well worth the price that I paid for it, $398 w/free shipping.The A-mount 35/1.8 is of course cheaper (I had paid $165 for it), but the E-mount version handily beats it in build quality, and appears to be slightly better optically as well.
And sometimes a wider angle requires a swapping with the zoom. These factors reduce its usefulness to me.I've had problems with the aperture blades not working. The aperture simply stays full open (1.8) resulting in a number of totally overexposed shots. IOW, the lens views and focuses while fully open as it should but does not close down to the proper higher f-setting.
Answer: Yes. Yes. Yes. And yes.  The lens is fantastic and has relegated all my others to a dusty shelf. The pictures are crisp and the bokeh is amazing. Seriously, don't hesitate. You won't be sorry.
