Have a look at samples of what the lens can do. @Rondec has produced many outstanding images with this lens.

Well that's straight from the horse's mouth - and from someone who has seen quite a few of them.
Originally posted by Flapentax Yesterday I was able to test the lens at a shopkeeper. It was used, the lens was very well kept but I was disappointed when I went home to see the photos ....... I didn't like the sharpness at the edges at all lengths and it wasn't that sharp even in the center , I didn't like chromatic aberration and the autofocus was really slow. I am already talking about it in the past because I have already decided. I would never buy it! I'm starting to save to get the 2021 model.
It was good that you were able to test the particular lens. Much frustration and inconvenience avoided.
The new version of the DA*16-50 sounds like a fine lens. But it is very expensive. And heavy - about 250g more than the old version. Which raises the question: is there a cheaper and lighter-weight lens that would meet your needs?
If you need f2.8 and WR, maybe look for a better copy of the old 16-50.
If you really need f2.8 but not WR, you might also consider the Sigma or Tamron 17-50 f2.8.
If you don't really need the extra width or length, consider the DA 20-40 f2.8-4 Limited. It's a beautiful lens, light weight, fine image quality, WR. You could pair it with a DA 15 Limited for wide-end coverage and a nifty 50 for the longer end (and faster aperture).
If you don't really need f2.8 (e.g. if you are mainly shooting landscapes at f8), consider the DA 16-85 that @K2 to K50; mentioned. It has very good image quality, good sharpness across the frame, and it's more versatile, lighter and cheaper than the new 16-50.
If you want a cheaper, less bulky and more versatile option than the 16-85, consider the DA 18-135. Sharpness across the frame isn't as good as the 16-85 and it doesn't have the HD coatings, but it's still a good option. Centre sharpness is excellent and edge-corner sharpness is acceptable when stopped down. Colour and contrast are very good. You could afford a prime as well with the money saved.
