[Astroman (Andrew Wall)]

Hi all,

Just doing some resaearch into clip in Filters for DSLR cameras. I used to have a Hutech IDAS-P1 filter that screwed onto a 2" adapter. I no longer use this adapter and no longer have the filter so I thought, what about the clip in ones...

What I am wanting to know is there any difference using a clip in filter against one of these screw in ones? I am also looking at the Astronomic CLS Clip in filter from Bintel. How do these filters compare (Astronomic v's Hutech) etc...

It would be used on an unmodified 400D.
