Sigma 19mm 'Ghosting' excessive?
May 3, 2012

Noticed that all shots with Sigma 19mm on Nex 5N in bright light exhibits ghosting especially on white, with or without the lens shade fitted. In comparison very little of the ghosting when using the Sigma 30mm or the Sony 55-210.

Can anyone else tell if they have similar effects when using the Sigma 19mm in bright light? Just want to know if there may be a coating issue with my 19mm. Thanks
