  1. I like the theory that nx1 does this thing with variable aperture lenses(50-150 is fine) but why is this happening with sigma 18-35 also?
  2. Thanks Tugela. So this happens with other cameras and lenses also? Manual focus and slower zooming doesn't remove the problem.
  3. So the feature works with third party lenses also? That's disappointing. Maybe the new gx80 would be better suited for my upcoming feature "Whip zoom to a coffee cup".
  4. Thanks guys. Looks like I've picked the wrong week to stop drinking. Anyone want to buy a nx1+16-50? Yes, it's a zoom lens but I like to think of it more as a series of primes for video.
  5. Thanks Don, so maybe this a feature with this combo? Are there any nx1 users who could confirm this? And maybe someone with a different zoom could test if they are able to get a "clean" zoom?
  6. Thanks for the replies. Forgot to mention that it was shot f3.5, 1/50, iso was 800 or 1600. And I'm not sure if the aperture actually changes after it's settled. I think it stays the same. This doesn't happen while panning from bright to dark(the old exposure drift problem). Only while zooming.
  7. Hi, Is the exposure change while zooming using 16-50 2-2.8 lens in the above video normal behaviour for a variable aperture lens? Or do I have a faulty unit? I've tried every auto/dynamic/framing/metering etc. setting and nothing seems to get rid of it. Both camera and the lens are equipped with the latest firmware. Other people have wrote about it also in the b&h reviews(http://www.bhphotovideo.com/c/product/1022903-REG/samsung_16_50mm_f_2_2_8_s_ed.html).
