Any opinion on the Samsung NX 50-200mm f/4.0-5.6 OIS Zoom Camera Lens for use with NX1?

@VisualFX:

Right. That's why "real" photographers usually shoot with crappy equipment because they can save money and noone will notice, lol! Contrary to what you say you can usually see the difference even without comparisons, especially when the light becomes challenging (that's a biggie, easy to spot for most with a bit of experience), when your AF needs to be fast and precise for action shots (another biggie and easy to notice for everyone), when you shoot in rain, fog, sea spray, wind and dust, when you shoot extensively in freezing conditions, when you need high resolution, superb sharpness and contrast across the frame for landscape and studio shots, or when you need a very thin depth of field and dreamy bokeh to get good subject isolation and 3D pop. Different lenses have different characters, and a good photographer knows how to employ the character of a lens, which is much easier when s/he starts out with a very good and well defined lens and doesn't have to battle stiff zoom rings, massive flare, flatness and washed out colours, softness and smear, lousy bokeh, dust or moisture in the lens and a half-competent AF. Tools for the task, as they say, and tools always matter as they allow you to define your style and the result in very distinct ways. Which does not mean that good tools turn you by default into a good photographer, and that a good photographer can't take a good picture with a smartphone (which is what you meant). But you'll always see the difference, and for those who shoot a lot, have a good eye and sell their stuff, the difference in IQ matters a lot. For the shots you take and your eye none of this may be of relevance.

Have a good one.
