hello guys i need your help . I m using a canon 500 f4 IS I and i m looking for filter to shoot under light pollution. I readed we can find some filters to fit in the drop filter of big white, like the IDAS LPS-V4 . it s hard to find information about it. Can you confirm ant tell me what size to buy, 52mm i guess. Any idea where i can buy this? a picture of the filter in the drop filter would be great. I barely undertand how to install it, according to the pictures of the filter i see on the web
I don't know about that filter specifically, but yes, you can put some small filters in there. I think people recommend slim 52mm ones. I have an Astronomik filter that's meant to go inside an APS-C Canon body, between the mirror and the lens, but it fits into the drop-in filter perfectly - I just place it against the glass and tape it down.
