Hi all,
Hoping you can help with some advice...
I recently bought a hama grau vario ND2-400 filter, 52mm. http://www.amazon.co.uk/Hama-Variable-Neutral-Density-Filter/dp/B004ZLVKRC
Been having problems when attempting long exposures. The bottom left and top right corners are often much darker and this effect meets in the middle. Ruining the picture effectively. I've tried it at different focal lengths. Just been out trying it at 42mm (as attached). No difference. I've tried screwing it in after putting a hood on but that's very tricky and didnt seem to make a difference.
Example. http://imageshack.us/photo/my-images/846/p1040152k.jpg/
Also tried putting a UV filter in first, no idea why really but it also didn't make a difference.
Fella in the shop reckoned it might just be glare and I should wrap my hand around the lens!
Any ideas? HELP!!!
PS, if it's just a pile of shit, cut to the chase and tell me :-D
