Excerpt: I just got this for my NX100, which came with the also very good 20-50mm lens. However, the 20-50mm does not have IS built in, so I've had some issues with sharp results at lower shutter speeds. This new 18-55mm with IS has helped me a few times already, and I don't see any loss in image quality between it and the original 20-50mm. The 18-55mm also comes with a reversible lens hood, which the 20-50mm does not have.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
Excerpt: This lens is pretty much a must have for the samsung nx camera line. The optical image stabilization is a great feature, and it is an internal focus lens wich makes it a quieter, and much stronger lens than the stock 20-50 lens that came with my nx1000. All around one of my favorite overall lenses to use.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Rugged, Strong Construction
Excerpt: I use this lens for everthing that do not need a big zoom. This lens is capable doing everything, from macro to portrait pass by landscape. The images are clean and beautiful. Seriously, i love this lens.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Excerpt: Objectif de kit efficace car bien stabilisé, avec un piqué très correct. Son bouton iFN permet notamment de doubler artificiellement la longueur de focale (iZoom) sans perte de qualité mais en diminuant le nombre de Mpx. Son ouverture faible, mais normale pour ce type de kit, lui font perdre une étoile car il manque de luminosité pour les photos de soirée et oblige parfois à sortir le flash.
