Hazy pictures with telephoto lens

I have a Canon Digital Rebel and was using my Canon EF75-300mm F4-5.6 IS lens to take some pictures at the park yesterday. I was using a tripod with the image stabilizer turned off. It was a sunny day, and I was taking pictures in open shade and in open sun (side-lit and front-lit subjects). I was shooting in aperture priority mode and was experimenting with all apertures. All of my pictures came out hazy and not sharp. They are in focus - they just look like I shot every picture through light fog or drizzle. What would cause this? I've never really gotten crisp pictures with this lens (I've only had it a couple of months) and I'm not sure why. Does this sound familiar to anyone? Am I doing something wrong?

Kevin Burns   Yes it sounds the same as the problem I have had.
1, Wide angle and telephoto lenses, do distort the picture a bit.
2, I found, that as long as I only, “optical zoom” in only enough to get rid of the black round casing that is seen threw the view finder, and then focus. the pictures are clear. You might be zooming in to close or to close to the subject.
A tele will render fine results if the subject matter is farther away “a little farther than normal”.
If I take a close up with a 2x’s tele lens, while I am close to the subject the picture is not so great. If I shoot about 2 to 4 blocks away the subject is clearer. A tele is for far away shots.
With a wide angle lens I use the macro setting.
This I noticed with a FUJI S3100 digital.

Michael H. Cothran   Wendy,
Your Canon 75-300 zoom, while not being a "great" lens by any stretch of the imagination, should still provide you with useable and acceptable images.

Being out of focus or blurry is one thing, but the "haziness" you describe sounds like there is a lens element out of place inside your lens.
Hopefully you have a warranty with the lens. Contact Canon, or the dealer from which you purchased the lens, and follow their instructions for sending the lens to a qualified repair center. If something is wrong with the lens, or one of the lens elements, they should replace the lens.

  Thanks Kevin and Michael. I was no where near two blocks distance with my pictures, but I was a pretty good distance - shooting across a grassy knoll area and a creek to photograph tulips on the other side. I played around with it some more on Sunday and got some clear pictures, so I'm not really sure what I did wrong at the park on Saturday. I'll play around with it a bit more and if I continue to have problems, I will have someone check out the lens.

Thanks for your advice!

This idea just came to mind...

Could the sun (or a strong reflection of it) been hitting the side, but just to the front of your lens?

For example:


Hopefully, that will come out.

But the idea I am getting is the sun flare in the lens coming from the side creating the 'haze' effect. Strong enough to create the effect, but not enough to get the haloing effect that is a dead giveaway?

Hope this helps!
