Rokinon 12mm f/2.0 NCS CS Wide Angle Lens for Sony E – Fast Aperture, Nano Coated Optics, Manual Focus, APS-C Mirrorless, Ideal for Landscape, Architecture, Low-Light Shots (Silver)

Pro's: + It does have a solid construction + It is easy to adjust + You will not knock this out of focus or F stop by holding the lens to capture a shot + The sun cover does help + It has a great depth of field + Great for video at 4k when the camera crops (M50) + Sharp details + The construction and mechanics never got loose after almost 1 year of use + Great for real estate photography Cons: It can suffer from chromatic aberration if left wide open and you are taking shots of a tree with a strong source of light breaking through (Fix is to bump the F stop to 4 - 8 depending on the situation, and bring the ISO to 200-400 if you truly need to) - It is slightly larger than the Canon options - It does not have autofocus Tips: Make sure to use edge detect and other focus tools are enabled to make sure you are in focus + Get Filters to help with tricky shots + Keep focus in infinite and bring slowly into focus to walk it back towards your subject if shooting between 3-11 feet

Build Quality: The lens is well constructed and relatively small. The lens mount is metal and the front of the barrel and the focus ring is plastic. It has a 67mm filter thread; my UV filter fits nicely and looks good. The aperture ring is a little small, but provides nice clicks with half stop adjustments. The aperture and focus rings are well-dampened, needing both fingers to turn. Close focus is a little less than .66m and it focuses a little past infinity, but there is a mark for infinity. The lens hood is a little cheap and also has a little play when mounted. Overall, the build quality is good and it would handle rough usage. Performance: The lens performed very well for my uses. I'm only going to shoot landscapes and nightscapes with this lens. The center is sharp at F/2.0, peaking at about F/5.6. The corners are a bit soft wide open, but sharpen up dramatically at F/4.0. When focused to infinity at the stars, the corners were surprisingly good wide open. The coma was well controlled too. It can do up to a 25 second exposure without getting star trails. There is little distortion, and there shouldn't be a problem fixing it in post. It has strong vignetting at F/2.0, but improves at F/2.8. Overall, it has excellent performance for a $400 lens. Other Thoughts: I set the C2 button on my A6000 to magnify so that it's easy to focus. It feels well balanced and is only a little heavier than the Sony E 50mm F/1.8. This lens is very aesthetic and looks even better on a black camera. Update March 2016: I use it primarily to photograph seascapes and for night timelapses. It's been splashed by ocean waves many times and it's still going strong. Compared to other wide angle lenses, this one is very small and light. It's perfect to take hiking if you want to bring the minimal amount of gear. I use a Tiffen 3-stop ND filter for shooting waterfalls and the ocean.

This lens really stands out as a high quality and inexpensive lens in comparison to the competition in this focal length. Your other options are the Zeiss lens with slightly better optical quality for a lot more money or the Sony zoom that is lower optical quality and still expensive. This one is the obvious answer is you can deal with manual focus and manual aperture. If you shoot landscape or astro, you're likely focused at infinity all the time, so manual focus is not a big issue. However, it seems that Rokinon has poor quality control resulting in some lenses in the market that are not meeting the expectation of high optical quality. If you get a good copy, I highly recommend this lens. The first one I purchased felt like the infinity stop on the focus ring was not quite at the right location, resulting in shots that were passable but not quite sharp enough. I got it replaced for free through Amazon in two days. The replacement was sharp edge to edge but noticeably about one stop darker in only one corner, which is not acceptable to me. Pros: - A steal in comparison to other ultrawide lenses in the market - Good build quality will likely survive a few drops - Relatively small and lightweight - F/2.0 for this price, great for astrophotagraphy but not important for other disciplines like landscape - Focus ring feels great, not squishy or hard to get very precise focus - Can use screw on filters unlike some other Rokinon wide angle lens In the middle: - Manual focus, you're probably parked at infinity anyway, but with focus peaking I can nail the focus fast - Manual aperture, I was shooting in A or M anyway, I actually prefer an aperture ring - No image stabilization, with such a wide and fast lens, image stabilization is not really needed, so why bother designing in an expensive feature? Cons: - No exif data because it's fully manual. It would be nice to have, but not absolutely necessary - Poor quality control!!! Make sure you get a good copy If you're interested, here is cheap lens case that fits well (size small) https://www.amazon.com/gp/product/B075LRNW8Q/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

Excelente calidad de materiales de construcción,casi todo metal, bayoneta metálica, pequeño y ligero, unos 250 g, enfoque manual (hay que activar la función de disparo sin objetivo en el menú de la cámara C.Fn: Otros). Y en el menú 4 activar el ajuste valor máximo MF para tener ayuda de enfoque. Control de apertura manual, lindo bokeh f2 y permite acercar a 10 cm del sujeto. Altamente recomendable.

The speed and sharpness is good, focus ring and aperture ring is of good quality and has a feel to it. Does not like the distortion and fringing.

Le ROKINON 12 mm F2.0 NCS CS pour Sony E-Mount est un objectif ultra grand-angle exceptionnel, particulièrement pour l'astrophotographie. Grâce à son ouverture maximale de f/2.0, il capte une quantité impressionnante de lumière, idéale pour immortaliser des ciels étoilés dans toute leur splendeur. La qualité optique est remarquable, offrant des images nettes avec un minimum de distorsion et d'aberrations chromatiques, même à pleine ouverture. Sa compacité et sa légèreté en font un compagnon de choix pour les photographes en déplacement. Pour capturer la beauté de la voie lactée ou des paysages nocturnes, cet objectif est tout simplement incontournable !

Easy to use manual lens. Takes great photos for the price.
