Frage von milchlubi:
Hello, 
 I've now been to a party SonyHC5 camcorder and I've now bought a wide-angle converter. Now, I wanted me some synonymous filter care. Only I do not know whether it makes a serious difference whether I change the filter now before the wide-angle conversion lens (46mm) or behind (37mm), ie before the normal lens attached. Advantage of the 37mm filters would then of course that I have with and without wide-angle converter could use ... and that the synonymous cheaper. Would be glad if I can help as a wide würd. 
 LG

Generally, wide-angle converter lens on, filter on the converter:

 Antwort von  Peter06:

what filter? 
 pol-filter should be in front of the converter. 
 when nd-filter will be no preference. 
 UV filters are only for the protection anyway because I would at ww vignetting due to reflections and do not use 
 at ir-filter, there will be no preference to be synonymous
 Antwort von  milchlubi:

it is about pol, and grauverlauffilter nd. where I stop when grauverlauffilter am not sure how it would look like if I do not weitwinkel the converter would make it. because the image is slightly distorted and of course would not be distorted. 
 and thank you for the link, just something I did not find very helpful.
