Canon 100-400 - which Lee adaptor ring - normal or WA?

[Buck]

Hi

I've just got the Mk 1 Canon 100-400 and want to put a Lee filter ring on it.

On my 70-200 I didn't need the wide angle one and I'm presuming that as this is 100 at its shortest a standard will do here as well?

If I use the standard 77mm one will it vignette at all?

I think I'll be OK with the standard one but would be grateful for any feedback.

Thanks

I reckon you'll probably be fine with the standard one - 100 isn't exactly a wide angle lens, even on FF! FWIW, Amazon do the Lee system and have a good returns policy - or visit a bricks'n'mortar shop and buy it there.
