Weird Lines

Hi, I'm new to DSLRs and just finding my way around the camera. I'm also practising taking photos with my new telephoto lens (canon: EF 75-30mm) I get a lot of Chromatic aberration and have the correction for it enabled in camera. I'm thinking it's mostly me taking crappy pictures, lol, plus I have an old sd card from an old canon point and shoot (which I'm replacing today). In any case, I'm hoping for help on identifying what these odd brown lines in this photo are (I outlined in yelow) and why they occurred? brown_lines.jpgIt almost looks like a type of shadow from the tree branches? How can I correct for this? Thank you so much for any help you can provide.

Hairs on the sensor.  Clean the sensor.

Re: Weird Lines

Really? This is the only pic that the lines are in?

Here is a picture of the front of my dishwasher. Other than the glare spots, are you seeing anything that looks like hair or other debris on the sensor?dishwasher.jpg

It was just a guess and the most easy to correct. Smiley Frustrated

That's just bizarre. Viewed at 100% these marks are surprisingly well focused and semi-transparent to varying degrees and never completely opaque. They extend even further into the frame beyond where they're marked in the sample photo. Does your Rebel SL2 have a touch screen LCD?

Re: Weird Lines

Do you have a UV or polarizing filter on your lens? Could these be reflections bouncing back into the lens from additional glass attached to the lens? Just a guess?

Re: Weird Lines

Both photos look to have been cropped or resized. Can you upload the originals?  

 

Exif data says the "brown lines" photo was taken at f/7.1 which wouldn't tend to show dust or hair on the sensor.

 

Exif data says the "dishwasher" photo was taken at f/22 but shows no dust, hairs or other debris on the sensor. 

 

I suspect the brown lines are just out of focus branches from the foreground trees. There really is no other explanation.
