Lens is clean and I wasn't using any filter. It gives nice images otherwise but its so susceptible to sensor reflection that it ruins otherwise good pictures. I don't use my DSLR much but I don't get it anything nearly as bad with the 18-55.

Weird, I own a 50mm 1.8 too but it rarely shows flares. Maybe something isn´t right with yours? Some misalignment inside or something. Ever dropped it?

I have the exact same thing with mine. I recon such lens flares are very common with cheaper fast lenses, since I've seen similar flare patterns with other brands as well.

Try shooting at a smaller aperture of clone the flares out in post.

Interesting discussion:

I didn't really think about it but it makes sense after I read it. DSLR sensor is glossy like computer screen while film is more flat like copy paper. So light goes through the lens reflects off the sensor which reflects off the back part of the lens and back to the sensor which is captured as flare.

There are multiple possible causes.
Always keep your lense optics spotless. A UV filter in front vented lens also acts as a dust filter, helping to protect it's internal optics from dust and moisture.
Always use a hood, even at night.

Diffraction artifacts:
One form of flare is specific to digital cameras. With the sun shining on an unprotected lens, a group of small rainbows appears. This artifact is formed by internal diffraction on the image sensor, which acts like a diffraction grating.

Ask the experts. See if Canon 2nd tier support with look at the image to dX it. They will do it for free on pro models, and may support non-pro issues as well.

I don't think I really understood what you were referring to when you mentioned it in avchat, but now that I look at the pictures I get it. I was shooting some stuff at night with my Canon 50mm 1.8 and had that issue as well. I'll be curious to try a smaller aperture and see if that makes any difference. I don't have this issue with any of my other lenses.

Few lens shoot well wide open. The 70-200 f/2.8 IS one exception; it's tack sharp wide open and just fantastic.
To spite it's bad reviews, I had the 50L and shot it wide open a lot with good results. Still it was much better stopped down if you had the light and didn't need the narrower focal field. Wide open this lense had superb flare resistance and night shooting was a blast with it. Something the reviews shamelessly tend to overlook.

Stopping the 50 f/1.8 down to f/2.8 - 4.0 will improve the image quality substantially at the cost of light gathering ability. Shooting wide open is one of the reasons to own fast lens and many times they require more expertise to milk the most out of them. For a Franklin you can't bitch too much about this prime, a lot of bang for the buck.

One thing the L lenses have is more aperture blades which renders them more flare resistant and better bokeh. Too many forget about that dreamy background blur and pop out image a fast, expensive lense can capture even when the subject is heavily back lite. It's not just for low light, and faster AF locking that you buy a high dollar lense.
