28mm, 1.8 - weird glow

[tommygunn]

Like many, I am jumping on the dlsr bandwagon. I am not totally green when it comes to shooting stills, but by no means am I a pro either.

Anyway, I am experiencing an odd glow around images that are bright or overexposed with my new 28mm f1.8. This anomaly happens on the video feature, too. I have never experienced anything like this, and it doesn't happen on my 70-200 lens.

Any advice is appreciated.

Thanks,
T

Do you have a filter on it? Cheap UV filters will do that.

 

[tommygunn]

Yes, a Tiffen UV filter. It happens with it off, too.

Are you shooting at your widest aperture, a 1.8?

Some lenses are a little soft at full open aperture. Most of my older Canon FD lenses do the same thing. Try stopping down for a clearer, less soft image.

Your lens might have a defect. Soft focus is "a lens flaw, in which the lens forms images that are blurred due to spherical aberration."

That's totally possible. I guess a call in to Canon is on the list for tomorrow. Unless someone call out my amateur shooting skills. :happy:

Your image shouldn't have a soft focus effect like that if you're shooting at f/8.0 with a fast shutter speed of 1/160th, as you've indicated. No amateur shooting skills in the world would produce that kind of defect.

Thanks. I've been scratching my head about this for two days. We'll see what Canon says tomorrow.

Stupid question, but is the lens clean? (front and back elements?)

It looks like a white pro mist filter was applied, but the same thing could happen with a smudge on the glass.

Brand spankin' new lens and camera.
