Blobs around the sun

Hi All. This picture was taken with a Rokinon 8 mm fish eye. Whenever I take a picture with the sun in the frame with this lens, the region around the sun has these multicolored blobs around the sun. The lens front was not so dirty. Is there anything I can do to reduce this? (btw pls excuse the blur, i think its because i forgot to change the focal length to 8mm and sr was on). The M 28mm does not produce such blobs.
(I put a link to the image, but it is not visible, sorry don't know what I am doing wrong, so putting the url here : https://picasaweb.google.com/arunava82/Rokinon8mm#5945953961537762786)

Maybe something dirty inside the lens?

When trying to get flare, you will get this if ANY of the elements are dirty or dusty. The front of the lens may be clean, but any dust inside the lens will cause these reflections, especially sand.

The red and green dots? Looks like it could be a reflection of the sensor.

Thanks guys for the replies. I will check for dust. But this is just a few months old lens.

Are you using a filter on the lens?

Can't use a front-mounted filter with the Rokinon 8mm fisheye.

I have the Rokinon 8mm and junk like that is not typical. Are those fibers I see at lower left? Dust on rear element?
