50-135 Normal Lens Flare?

I notice whenever I shoot my 50-135 at night I tend to get particular flare like the little dots that look like UFO's if there are bright lights.

Is that normal?

Nope, not for me anyways.

Is there a filter on your lens?

What settings did you use? It looks like you used a higher f-stop and a longer exposure than Goremanx, could that have any effect on the reflections?

ugh, come on dude, now you just made me lug my big-ass tripod outside in the freezing cold I hate it when people strip out their EXIF data:

note: I made NO effort to make this look good, it was just for testing purposes. No permission to criticize the crazy angle.

edit: wow, 18-point starbursts are pretty...

Hmm strange, however you did shoot at ISO 200 for that second shot, so maybe it has to do with higher ISO's combined with longer exposure to get reflection? Lol I hope you have a jacket on. Maybe you could try mimicking Tsorotes settings and see.

Without actually going out there and doing it, on my first try, I also used ISO 2500 and got the same results (but with lots more grain).

Must be something specific to his conditions or a defect with his lens. For the record, I purposely used no hood either.

His shot does have significantly more light than yours, so it could be. I wouldn't think Pentax would use an inferior coating on his 50-135 than yours.

Hmmm...well those lights are in the distance on mine are fairly bright, it only seems to happen when I aim it on particular cityscapes at night.

I should also note that I am pretty much horizontal to those lights in the distance that may be why. I took a sequence of photos during the evening (time lapse) and notice that when one light in the distance would go on and off the light light flare would do the same.

One difference between CW's and Franks pictures are, CW is shooting over the city and the lights are distant, Frank is shooting from ground level at lights that are nearby.

I suspect the 'lights' are caused by some kind of refraction caused by atmospheric conditions in that kind of situation.

I moved OUT of Montreal because I was sick of the big lights (and for other reasons too)
