Frankly not many keepers compared to the humble DA35/2.4. Right now, it seems the 16-50 is much like the 18-135 with a larger aperture. But I will use it more often to give it a fair assessment. The DA15/4 and DA35/2.4 have more wow effect straight out of the box.

Woah! This is just full of flare indeed, and I think you may:

1. have a very bad copy
2. have a lens that has dirt on it
3. have a combination of both above.

In your particular case, if this is not caused by dirt, I would recommend that you send it for a diagnosis at a repair shop.

Weird indeed that some of us don't have this problem while some other do.
But I wouldn't say that this is the worst Pentax lens ever produced.

Best of luck.

Just another shot (this one at 16 mm and f5.6) shot directly into the sun. Once again, a little bit of flare, but still pretty good overall contrast.
There is a butt load of veiling flare visible in that shot.

as others said, any filter will potentially introduce more flare when shooting into a light source or strong oblique light. as far as i know, you cannot use a filter to reduce flaring.

You clearly either had a dirty filter on the front, or a dirty front element.

I just have never seen anything resembling that, but maybe copies differ...
No filter and no dirt (dirt do not create aperture shaped flare). It is just stopped down to F:16. At wider aperture the flare will be less in focus and visible as a reduction in contrast. I have a great copy of the lens; high resolution and correctly aligned...

Test: Point the lens at the sun. Stop down to F:22 and see whats happens...

This reminds me of when I used a cheapo Green.L filter on my DA15ltd. It had the same results. I may have missed it but what filter are you using with it right now?

As I said; I never used a filter on this lens.

Whatever he used a filter or not, the point is:

The DA* 16-50 is NOT the worst lens ever produced by Pentax and, to get back to the meat of this thread ... I would NOT use a filter to try and cut out the flare for any lens.

There is no filter that can cut flares, flares are internal reflections which are always there if the coating(of the lens) is not good enough. But there are filters that can add flares - the cheap filters which are not coated good can add flares of themselves. For example if you have 3 street lamps(lights) in the frame with bad filter they will become 6(lights) 3 real and 3 reflected if they are strong, but if you have flare issues caused by the lens there are going to be 3 lights and 3x(number of lens elements inside the lens) reflections. For the sun situation it is the same, if there are flare issues you will have reflections in the frame and the contrast will be awful.

I have never said it is the worst lens produced by Pentax. The lens is excellent (exept for corner sharpnes at wide aperture and some fringing). However, it is probably the most flare prone lens Pentax have made. At least it the most flare prone lens I've ever seen; it flares more than the fish-eye zoom!
Point it at the sun; stop it down to F:22 and engange DOF preview. See what happens in the finder....

Again, the lens is clean.

The lens is apparently due for replacement and I suspect its bad flare performance could be one reason....


I will replace mine in due course with the Limited zoom + the 15 Limited....

After much anticipation the 16 50 was a big disappointment.

everyone should grow up and be a little more considerate. I finally went back to see what pic was being discussed.

Those anomalies look just like tiny water droplets on the front element. obviously you arent at the beach but is it possible this is condensation?? I get the exact same thing (no matter the lens) when ocean spray blows on my lens. I doubt this has anything to do with the design of this specific lens nor would i think it is defective.
