Having purchased a NEX 5R a couple of months ago, I immediately began researching lenses to complement it. I didn't have the money to get the Carl Zeiss 24mm lens, but I have picked up Sony's excellent 50mm lens and wanted to pick up lenses on the wider end. I've read many good reviews for Sigma's lenses, the 19mm and 30mm, and ended up picking up both lenses for around $100 each (sad to see that both appear to have been discontinued according to Sigma's web site, but I hope that does not discourage them from designing and offering more E-mount lenses for the NEX line). Both lenses have been excellent additions to my camera system. Unlike many of Sony's own lens offerings, the Sigma lenses do not have optical stabilization, so please be aware of that. Knowing that, I try to use a tripod for indoor photos, but find that they both work great hand-held in outdoor daylight. As mentioned in many other reviews, these lenses offer great sharpness with little to no distortion or chromatic aberration. Admittedly, I use the 30mm lens more often, finding that it perfectly complements my 50mm Sony lens for portraits. I'll use the Sony lens for medium shots and close-ups and use the Sigma for group photos. I still would like to be able to pick up Sony's 35mm lens ($450) because of its built-in optical stabilization, but the Sigma is a great alternative that I was able to pick up for $350 less. It may not be aluminum like most of Sony's offerings, but the plastic is sturdy and has enough heft that I do not worry about it. And the glass is typical of Sigma's great product line. Although it lists for between $140-150, it can be purchased new for as low as $100-110. So, depending on your needs, do yourself a favor and pick up either of these great Sigma lenses while they're still available at such great prices.

There is huge dust particle that looks more like damaged glass inside of the lens (sensor side). Exactly the same damage on two lenses I ordered. Both lenses had dust particles inside of the lens on the other side too. First one was ordered through Ado*ama. Terrible service. Took them eight days to respond to my email. So, I had to pay return label. Amazon sends labels automatically while they initiate shipping of the replacement right away. Hopefully, 3rd lens will work. Otherwise I'll have to sell my Nex 5N (Sony 16mm fast lens, as the option, is not going to cut it) UPDATE: ------- Got 3rd one. Still there is dust inside of the lens. Also, I got it with dust and dirt all over the lens.

I'm using this on a Sony NEX 7. This lens isn't perfect: it has some visible distortion, and it vignettes an awful lot at wider apertures. It's also awful plasticky-feeling, and I strongly suspect that it could have been a stop brighter, or more compact, or maybe even both. That said, it actually takes really nice pictures. I bought this so that I would finally have an autofocus lens for the NEX, since everything else I use are old manual lenses, and I wanted something for grab shots. I was really surprised at how well it performs. The colour isn't as good as some of my more expensive manual lenses, but it's great for an AF lens, and ditto for the sharpness. CA and other lens problems are fairly minimal. For the low price, I has absolutely shocked how great the pictures look. Maybe that's because they used nicer glass instead of going the wide aperture route, I don't know. I do know that if you're looking for a relatively compact, sharp walking around-type lens, this is a fantastic choice for the money. If it cost twice as much as it did, it would still be a decent, but not phenomenal, value. At it's current price, it's just amazing.

I bought this lens after David Taylor-Hughes and Roger Cicala independently described it as the lens deal of the year. If you want a dissenting view, see Kurt Munger's review: he suggests this lens is too similar to the 18-55mm kit zoom lens that most NEX owners already have (the Sigma allows larger aperture, the zoom has SteadyShot). Like others here, I have found this lens sharp, smallish, lightweight, inexpensive, and a useful focal length. However, for my style of photography, I think Kurt has a valid point. Background: I purchased a NEX with the kit zoom. I next purchased the Sony SEL 50mm f1.8 and it was a revelation. The wide aperture and longer focal length are excellent for portraits (aperture allows great bokeh, focal length provides pleasing perspective). The fast aperture is also great for dim (indoor) lighting. While this is a review of the Sigma lens, I do think most people should get either the 50f18 (better for portraits) or 35f18 (better for indoors) before considering other alternatives. My style of photos is to use a wide angle lens with small aperture for landscapes and architecture photos and to use the 50mm with a wide aperture for pictures of people. Performance (see my gallery for images): On my 16mp NEX 5N the differences between the Sigma and my 18-55mm kit zoom are subtle (and are most noticeable at the corners of the image). Perhaps the 24mp NEX 7 is better able to detect the defects of the kit zoom. However, I also think the type of photography does plays a role. I tested all my lenses on a bright day shooting distant buildings at ISO 100 and f5.6-8. The kit zoom performs very poorly at 50mm with a distant focus (see photoheadonline for examples) and the 50f18 was clearly superior. However, in this situation my zoom performed very well at 30mm. The Sigma was only marginally sharper, particularly in the corners (though it exhibits a little more chromatic aberration). I next shot indoors at about 10 feet, where a higher ISO (400) and wider aperture (f4) was appropriate. Here the Sigma does outperform the kit zoom by a wider margin, though unless I pixel-peeped I would not have noticed a difference. All images were taken raw and I used the provided LightRoom lens profile corrections. However, for all these comparisons I used a tripod, so the zoom's benefit of vibration control was eliminated. When used hand-held indoors, I did notice a higher portion of my Sigma photos show vibration artifacts, so you need to watch your shutter speed and your shutter technique. Design/Size: This lens appears to be derived from the one in the Sigma dp2 Merrill, with one less element (I assume the dp2's huge rear element allows the more compact design) and one less aperture blade (so stopped-down bokeh will not be quite as round). This lens is about 2/3 the size of the kit zoom but much larger than pancake lenses. I feel it is a nice size: good balance and nice sized focus ring. Reflections on the kit zoom: some love this lens, some loathe it. I think this reflects different usage. My own findings match the photoheadonline and lenstip reviews: it is good with f5.6-f8 and in the middle of the focal range. Good photographers bat to the strength of each lens: see the lovely landscapes David Taylor-Hughes has taken with this zoom. In sum, this is a fine lens and a good value. But ask yourself this: do you need it? For me, I will always travel with 50f18 along with either the Sigma (more compact, sharper) or the zoom (more versatile). Carrying both the Sigma and the zoom seems superfluous. I bought a mirrorless camera because it is compact, and it is strangely gratifying to discover that two lenses are sufficient to cover my style of photography.

The sigma 30mm f2.8 is a compact lens designed for a future compact mirrorless by sigma, but has been ported to m4/3rds and the nex mount. The 30mm translates to 45mm in 35mm terms, which gives us an almost normal focal length. Along with the 19mm, Sigma has created the first third party autofocus primes for mirrorless systems. Neat! The lens is compact in size (about the size of my 50mm 1.7 Minolta AF lens), and the front element is VERY small. The back element is large, allowing for a small design with minimal distortion and good coverage across the frame. The most important features of this lens are the focal length, and size. 50mm is often the most desired focal length in a system, which is 35mm in APS-C terms. Since the NEX system has large amounts of adaptable glass, this would seemingly be non-issue. But 35mm lenses are large for film cameras, due to retrofocus designs. Often the adapter and 35mm lens combination would leave you with a very long lens, and fast aperture (as in f2) 35mm lenses are even bigger. The only convenient options in terms of size available until this lens were the 35mm f1.7 CCTV lens (which has unbearable corner performance and vignetting, though a good lens if used stopped down marginally and centralized composition), the Contax G 35mm f2 (hard to come by, and the adapters are expensive, and lastly the Voigtlander 35mm 1.4 (very good lens, small with great construction, but expensive). So this lens represents something pretty significant, especially considering the autofocus capabilities. Sharpness: The sharpness of this lens is unreal. Bar none. On MTF curves for the Nex 7, it beats out Leica lenses (scored in the 1000's wide open in center, and high 900's stopped down in corners). This is the sharpest lens you will put on your NEX, bar none. And that's from wide open. The lens has maximum sharpness at 5.6, but hardly improves over being used wide open. That means you pretty much only stop down to gain DOF. For this reason alone, I highly recommend this lens. Being a normal focal length and having this sharpness, you get a compact walk-around kit capable of anything from portraiture to landscapes. Focus speed: The focus speed of this lens is pretty quick. Though it uses CDAF, I had no problems with speed on my Nex 5, performance should be better on a 5n or 7. The focusing speed was not as quick as my 16mm, but probably rivals the 18-55 kit lens. This will not be as fast as Phase Detection, but it is quick enough for what I need. No complaints here, not something I would use for sports or candid moments, but that isn't what I shoot anyways. The only fault for focusing is while using facial recognition, sometimes the focus will not be correct. I have only encountered misfocusing while using facial detection. So either turn that off, or make use of the excellent DMF built in, which will zoom in on the face with a turn of the ring, and allow precision focusing. Build Quality: The build quality is good. It uses a metal mount, but unlike the Sony lenses it is made of hard plastic as opposed to aluminum. That's not to complain, because it's durable plastic. The focus ring is well dampened, and I have had no problems with the focus-by-wire design. It also supports DMF (direct manual focusing) as do all native Nex lenses, which is great. This isn't a lens I would worry about taking anywhere. Pricing: Can be had new for $200, used for a little less. If you want a normal equivalent prime for every day, and not dying for fast aperture, buy this immediately. If you want a fast aperture lens, buy this and then spend $40 on a 35mm CCTV fujian lens, as that will cover everything this doesn't at this focal length. Some side notes: Fringing is extremely well controlled. Wide open it is practically non-existent, and of course goes away as you stop down. Flaring is also not an issue due to the small front element. If the sun is in the shot, it will not do much to the image at all. It does provide a green flare, as opposed to a red style ala Canon. I would try and avoid purposeful flare, because it isn't attractive looking at any aperture because of the color signature of the flare. The color signature of this lens is great, and is of other Sony/Minolta lenses. You will have more blue/purple as opposed to hard reds and greens from Canon. Minimum focus distance is nice, not replacing a macro but much closer than the 16mm. You can get some nice close ups with this lens. Bokeh is decent, not very smooth but not at all distracting. The aperture blades are rounded as well, a nice touch especially for price range. Vignetting is minimal. Optically I cannot fault this lens. Some might complain that the aperture isn't very fast, but you should buy this lens not trying to get a narrow DoF. This is a multi-purpose lens, and 30mm is not a focal length which will have shallow DoF regardless of aperture. If you are dying for shallow DoF use a longer, faster adapted lens. Wide open performance of this lens is perfect, vignetting is very minimal, and you can achieve narrow DoF depending on distance from subject, just don't go expecting to make a bopie with this lens (as in you can always get background bokeh, but don't expect foreground bokeh. If you are DYING for a fast aperture 50mm equiv, buy the Mitakon 35mm f0.95 [...] and receive few of the things that make this lens special. The only faults I would attribute to this lens are the 46mm filter ring (the standard for MFT, but NEX uses 49mm. Just buy a step up ring and new cap, should set you back $5 at most), and the lens slows the operation of the camera. For whatever reason, start up time and switching from image review to shooting are slower with this lens attached. I have tested this against adapted lenses and my 16mm, and the operation of those features are much longer with this lens. Why? I have no idea, but it is worth noting. This means you can lose the moment from doing image review. I suggest turning auto review off (because you can pretty much see what the picture will look like anyways due to EVF), and not reviewing images often. It is a VERY glaring error, but one that can be overlooked in favor of the pros of the lens, which are abundant. It also doesn't have any sort of stabilization so it's not ideal for video, but that would add to price and size so it's not the end of the world. Though shaky video is pretty easy to correct, detail will be lost that way. If shooting video try and use a tripod, or wait for the 16-50mm G zoom by Sony in a couple months. Oh did I mention this lens is $200, and the sharpest lens for E mount? Sold. Pros: -sharpest lens for the E mount -$200. So cheap, and yet an EXCELLENT performer -small front element prevents flare or accidental damage -compact size brings nex to near pocketable status, it's not the 16mm but close. -overall performance is incredible, and will beat practically any 35mm lens you can put on the camera -plastic construction appears to be durable -it's $200, and beats leica lenses in sheer sharpness. Cons: -46mm filter size -slows some of cameras operations. Kind of cons?: -2.8 aperture -No stabilization Overall the only real con of the lens is the slower operation. While a 49mm would be nice, maybe an f2, and stabilization, they would add to the size and expense of this lens, compromising some of the best things about it. If you learn to use this lens, you will love it, and that's it. You won't think about wishing it was faster, because at f2.8 it's sharper than any other lens at f2.8, and your camera will be small and portable. The only thing that will irk you is operation time, depending on what you shoot. Chances are there will be times you miss a moment due to this. But the images you do capture, will be some of the best rendered photographs you could make with this system. Update: I purchased a step up ring for this camera, 46mm to 49mm. the cap still fits the 49mm without falling off, sweet!

Great lens if you are willing to sacrifice flexibility for (almost) pro image quality, while keeping the price low. Sharp wide open, it further improves at f3.5/4, focuses fast on my a5100. Makes it a good combo to shove in a bag. Good focal length for food & street photography in my opinion. Takes good portraits, just avoid closeups. The max aperture provides some separation and decent bokeh, but do not expect thin in focus area at this focal length. Lightroom recognizes it and corrects it just fine.

I bought this lens after reading a lot of good things about it. It is the first Sigma lens I have owned. The lens seems well constructed.. mostly plastic parts but tight and a nice finish. I am using it on an original NEX 5. The images are sharp, nice color, and contrast. I have paid a lot more for a lot less in lenses. I would recommend it as it is small, light, a "near normal" lens (45mm equiv) on the NEX and is fast to focus. I have used it with the flash and it gives excellent results. So, for the price it is a good choice for those who want a prime in this focal range. I like it.
