Sigma 30mm f/1.4 DC DN

It's sigma so it feels great, looks great and shoots great. Paired with a Sony ZVE-10 is a perfect small form factor power house. 30mm is a really nice happy medium for everyday shooting both lifestyle and portrait stuff. Auto focus is immediate. It really is hard to take bad photos with this lens. Small, light and well priced highly recommended for the a6k series or Zv series

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.

It’s my first time with that thin aperture dimension, and it’s crazy! The sharpness and the DOF are another level. Works perfectly with my Sony a6400. I am still have some flags regarding the manual focus but I haven't explored it so much yet. But overall highly recommend it

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.

As I spent my learnign months using only the sony a6000 kit lens (zoom lens) I needed a new lens. After research on quality and price check this seemed to be a good lens that matched my expectations. And it is what I expected from it. Using only zoom lens for a year, it was a challenge to try this one. But being a prime lens with a large aperture of 1.4 it helped me better integrate in my instincts how the aperture and distance from the subject in focus affect the look of the bokeh. The warm tones, the clarity and overall performace at high and low aperture make this is must have for any beginner or even for other pro photographers as well. To me Sigma is now a company I can trust and I am thrilled for my new purchase when I will afford to upgrade my gear.

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

For the price, this lens's performance is amazing. It takes brilliantly sharp images and amazing bokeh depth of field with the wide aperture this lens provides. Low light performance is also amazing. I would absolutely recommend this lens to someone who is looking for a good performance lens at a cheap price (In the photography world). I should note, that as of the time of this review, the details provided in the advertising of this product on this amazon page states that it has a 7x optical zoom. This is not the case, since it's a prime lens.

Image Stabilization: 5/5 because this is handled mainly by the Camera Auto-Focus: 5/5 because it is incredibly quick, again, partly due to the Camera Low Light: 4/5 Although it is F1.4 you will struggle if you don't have a tripod in Low-Light Overall Review (My Case) The colours produced by the lens definitely have a darkened tint to them, some would even say flat, but I wouldn't go that far. Obviously this can all be edited in post through Colour Correction. But this is also a known problem with Sony Cameras as a whole I believe, so it might not be the fault of the product, but of the sensors on the Cameras. Either way, It is still a fantastic lens for the price, and also the widest Aperture (F1.4!). I would recommend this to everyone with an e-mount camera especially if this is the first lense you buy, which it is in my case, with the (still fantastic) Sony Alpha A600. Also I did manage to get mine for £20 cheaper through purchasing an Amazon Gift Card for myself. So it might be worth trying to get that deal next time it appears!
