Hi all,
I have finally had it with my Lee snap on filter system (the one employing a rubber band to attach the filter holder to the lens) and I will replace it with a Cokin P system (I'm using this for backpacking, so I opted out of the Lee foundation kit due to bulk/weight).
One of my lenses is the 100mm wide field ektar. A search on this site yielded a comment that the lens has a 40mm thread size, while Kerry Thalmann's site mentions an odd size (approx. 39.5). Does anyone know which of these is correct? If the thread is not a common one, do I have any options for a slip-on adapter other than having S.K. Grimes custom make one? Finally, have any of you experienced vignetting issues with this lens/filter system combination (i.e., should I find a wide angle step-up ring, saw off a second filter slot, etc.).
Any and all comments are appreciated. Thanks!
