Excerpt: I use this lens with my samsung nx 1000 so frequently that I haven't carried the 20-50 kit lens around since. in terms of sharpness it is pretty comparable to the kit lens and gives a good level of sharpness above f3.5 with some soft corners wide open which is generally to be expected. What makes this lens particularly good compared to the kit lens even though it is optically very comparable is the ergonomics and focusing speed.
Summary: I have no idea if this is the fault of the camera (NX300), or the lens. However, I found that when I used it in any of the AF modes, it would not hit focus at the intended point. Without the ability to fine tune these lenses, I found this one to be out of spec IMO. That and the fact that it is only an F2.8 lens make it a 3 - 3.5 star lens to me.
Perfect to keep the DSLR camera in the girl purse.

Summary: Sooooooooooo much convenience to keep the camera in my purse and be with me any moment I need a great camera to get the picture. Plus the lense itself gives you the wide length to your picture. You will like it so much once you use it. I promise you!
Summary: As a beginner photographer I found that this lens works great for indoor low light portrait situations. In many instances it obviates the need for the use of flash. In addition it slims down the camera to the point that it is quite easy and convenient to bring along to indoor family events or where portrait photography is common. Extremely satisfied with quality, easy of use, and value for the money. I recommend it.
Summary: A nice, good quality, fast focus acquisition, solid, good field of view lens. The Fn button on the lens is redundant, but nice. If purchased, the 30mm should be a bit flatter as it does not have the Fn button. This lens take a 43mm filter, the OEM 20-50mm lens takes a 40.5mm filter. This can be confusing as my previous experience with several SLR/D-SLR cameras filters have generally been of the same size, except for speciality lenses.
Summary: This lens has been the perfect companion for my Samsung NX100 camera. Perfect focal length for take-anywhere photography. The image quality is very respectable. The focus is a bit on the slow side but not a deal breaker. Overall, great value for the money and makes photography fun.
