Hi guys,
I'm new to the aviation photography scene but have started shooting with a Canon DSLR and 18-300mm lens. I've noticed many people are using lens hoods, but whenever I use mine, I get a vignette effect on all my images. I only shoot during nice weather (clear skies) and would like to understand how to use my DSLR to it's full potential and get rid of this darkness around the edges as it's spoiling some of my images.
Regards, Leo |

Hi Leo,
Vignette effect ! Are you using a ND filter ?!
Kind regards |

I´ll take a guess that you are getting the effect at the lower end of the zoom range. If so, then this is causing it. Take the lens hood of and see what happens. |

Hi guys,
I'm not using any type of filter, I had a UV one on my old IS 18-55mm lens but it's too small to fit on my 18-300mm lens SIGMA. I have taken the lens hood off and it's still got the vignette effect...
Thanks. |

That's perhaps a stupid question but what kind/model of Canon do you have ? I prefer to ask since this Sigma lens is specific for APS-C formats ... |

Hi Leo.
I guess the vignette has nothing to do with your lens hood.
You shoult try and shoot A-mode and F8, although the vignette can be corrected in Photoshop.

Could your lens be a Sigma 18-300 mm?? Maybe the problem is there, not in the hood or the filter. Those kind of lenses (superzooms and "cheap") are not the best if you want very hight image quality. Of course you can get great pictures, but you will have to work harder in postprocessing. Take a look at this link where you can see the amount of vignetting that you get with a 18-300 even at f8: http://www.lenstip.com/427.8-Lens_review-Sigma_C_18-300_mm_f_3.5-6.3_DC_MACRO_OS_HSM_Vignetting.html |
