- I have one - from memory (it's at home) the big annoyance with it is that
- the filter mount/front element rotates and retracts. Retraction is a big
- problem if your filter has a diameter greater than 52mm. For example, my
- Cokin P filter holder, even though I have a 52mm mounting ring, is much
- larger in size than this. Because of the retraction, it is unusable (without
- modification) between about 35mm and 50-something mm in the zoom range.
- If you stick to one end or the other, you're OK, but this defeats the purpose
- of a zoom. While you can always put a couple of empty filters (punch out the
- glass or something) on before your Cokin, this will usually result in
- noticable vignetting at the wide angle end of the range.
