This how the front hood (with CP filter) looks like:






-> What I like about this set-up, is the whole hood/filter assembly easily slip in or out with no need for rotating the filter off (or screwing it back down), much quicker this way - Once off the bulbous front already has a tulip shaped permanent hood (albeit very small) right below the removeable one...

The hood looks different to the one in the picture I looked up on Amazon.co.uk

That's the lens own permanently fixed tulip shaped hood:
" - Once off the bulbous front already has a tulip shaped permanent hood (albeit very small) right below the removeable one..."

-> The external hood (in my picture) where the filter goes on just slip over the internal smaller hood :idea:

Thanks, I am just confused about how the lens cap is applied for protection with this hood?

Normally the lens cap latches on to the threads where the filter is (on the removeable hood) - I use a "slim" line B+W filter so there's is no front thread for the lens cap to latch on top (plus my camera is a 1.3x crop) to minimize the vignetting, but if you were to use a regular filter with "stackable" front thread then that's where the lens cap would latch on...

-> It's also kind of silly to put another layer of protection (i.e. the lens cap) on top of the protective filter anyway

You can't use the removable hood with the FF bodies unless you like extreme vignetting. Actually it's kind of an interesting effect.

Actually your comrade from the UK "doctored" this removeable hood to fit a Cokin... :idea:

The Sigma Arrieved today, it comes with a small thin squarepiece of metal that has one small hole in the cornerknown as a guide plate, that does not connect to the lens.
What could this be?:?
