My two min-kits are Pentax for WR, NX300 for the rest :smile: and both companies are bringing forth a strong contender in this focal range. We think! Pentax' 16-85mm has just arrived, weather sealed but f/3.5-5.6 means slow at the long end. Seven aperture blades, 1:4ish close focus, 72mm filters, 488g so pretty bulky. First images are good -- of course they are, why would a new owner post lousy ones? No rigorous tests/reviews are yet online but those should appear in the next few months. Samsung is planning one for this year - or so They say - rumoured NX 16-80mm is a straight f/4 with OIS. Not an S-series so probably no seals, but likely more compact - and f/4 at 80mm is definitely preferable! Clearly no tests in the real world for a while Some comparisons can be dared without Samsung details. They've made nothing for NX with less than seven aperture blades that I know of so that should be a draw. Other than the 50-200s by each, the Samsung zoom lenses generally come in smaller and lighter even with OIS. Even if they needed 67mm aperture that would save cash on filters, and maybe they could manage 62mm? Even with no true facts the Samsung is pretty appealing - but price and general IQ will definitely help to solve this riddle in the future. Hopefully soon! Other folks have Canon Nikon or Sony equivalent lenses to compare, about which I know nothing.. er slightly less than the Samsung. I expect one of these to be in one of my bags late this year - let the contests begin!
