Sigma 30mm f/1.4 DC DN SLR Standard lens Black

If you want a camera lens that is consistent and good for value this is the one. You’ll learn so much from this lens and you really learn the basics of photography. The best starter lens for sure. Image quality is impressive, and that low F/1.4 it’s so easy to get brilliant photos.

I've attached a couple of unretouched, straight-from-the-camera examples that hopefully show the sharpness and bokeh of this lens, in low and bright light. What's great about the Sigma 30mm f/1.4? Firstly it's sharp and bright! I was able to get pin-sharp results handheld at night with just a table lamp in the room. Secondly, it feels like quality; with nice weight in the hand and is reassuringly solid to the touch. The focus ring turns like butter: perfect. Value for money, this is a no-brainer: the Sigma lens is easily as good or better than more expensive alternatives. My only possible question about this lens is the bokeh, which I'm still trying to make up my mind about. Purely subjective of course but is it a bit busy in bright light? Overall, this is a definite "buy" if you are looking for a very good quality lens with a bright aperture and don't want to spend a mint.

This is the first sigma lens I have owned and love it. Fantastic quality easy to use. Quick focus Speed image quality as unbelievable, nice and light and compact

Bought this lens for my Sony A6300 a few months ago. Using it for both photo and video but primarily video. It's nicely built as we've come to expect from Sigma's Art and Contemporary series. The picture quality is amazing, really sharp and the contrast & colors are very pleasing and natural to look at. Not quite on the Sigma Art level but certainly close which is amazing given the price. Like mentioned by many others, it's great in lowlight with a minimum aperture of 1.4 or if you simply want that shallow depth of field look. Sharp all the way through pretty much, I mainly shoot between 2.0 and f 11.The only flack I can give it is the autofocus which I'm surprised many Youtubers reviewing it, haven't talked about more often. It is pretty jumpy and hunts quite a bit when filming lower lit scenes or fast camera movements. It's not terrible but the main problem is that it is hunting a lot, so going back and forth when looking for the point to focus on. This means it can mess up some shots completely in certain situations as it is pretty jarring. I've tried to update the firmware and change/adjust my focus settings but it didn't improve by much.Concluding I would say this is a great portrait lens and amazing to film experimental or very controlled scenes (like low budget music videos, interviews or short films) with. Any run and gun stuff where autocus can be really important, I would use it sparingly. Picture quality & look are fantastic, build quality is top notch. Overall, a really nice product!

I have recently switched to Micro Four Thirds from Four Thirds, and this lens has been the best thing about the move. Lives pretty much full-time on my Olympus OM-D EM10 Mk II (a great camera of itself). When I bought that I also got the Olympus 25mm f1.8.....an excellent lens in its own right, if there's a difference between that and the Sigma it's in the latter's colour rendering (I like full, rich colour and the Sigma deivers that in spades, maybe a little saturated for some tastes). And images are pin-sharp 9.5 times out of ten.The Sigma is a much bulkier lens than the Oly, but on the EM10 it adds substance to the overall look and feel of the camera in use. On the EM-5II it looks pretty standard, and is equally a joy to use.The advisory......reading about this lens online brings up references to a tendency to focus-hunt, even stopped down and in good light.....have to say I have seen this on the EM10 and it can be distracting. I will check it out on the EM5 as well. What appears to eliminate it is to set the camera to S-AF/MF, though I will monitor this aspect of performance. I can see that for some it would be a deal-breaker - it isn't for me as the all round optical performance is that good, and I'm finding 30mm a better focal length to work with than 25mm for everyday, carry-around use (though in a bag rather than a pocket given the size of the lens). On Olympus cameras the lens firmware is updated with the lens in-situ, and I'm using the most recent version. It's not a consistent issue, but it is a noticeable one, and hopefully there is a fix somewhere down the pipeline. I'm looking forward to the 16mm f1.4 version of this lens, and it would be a shame if that were similarly afflicted.But if you have an m43 camera, this is a lens you really must have. The focus issue is the only slight downside....in every other respect this is a lens you are likely to become seriously attached to. Go and enjoy.

After lots of reviews and YouTube videos looking at a lens to upgrade from the 18-50mm kit lens, I decided to go for the 30mm 1.4 sigma prime and all I can say is WOW. This is the fastest apature lens I've ever owned and I can say the difference from the kit lens 3.5 apature to 1.4 is incredible. I chose the 30mm as its the cheapest of a the 3 sigma primes and is the best all round for me. It works perfect with my Sony A6400 and I have had no issues with auto focus like in some reviews. This really does take your photos to a different level. The fast apature makes low light photos much easier and in good light allows you to bump your shutter speed to collect sharp images. The only thing I have noticed is its noiser than the kit lens when auto focusing but for me that's being picky and as I don't do a ton of videos it's no issue. I'd highly recommend this lens as an upgrade from the kit lens.
