ktos uzywa innej oslony z serii EW-83* jako zamiennik do tej zalecanej EW-83E?

cytat ze strony:
"To recap: the EW-83E hood that is standard for the EF 17-40mm lens (and the EF 16-35mm and EF-S 10-22mm) is very wide, and will not easily fit in lens pouches/etc. If you're using this lens on a 1.6x-crop-factor camera (i.e. D30/D60/10D/20D/30D/300D/350D/400D so far) the EW-83E does not provide adequate protection against flare. You can use different models of EW-83* hoods (designed for different lenses) to achieve a much better result. Of course, when you use the 17-40 or 16-35mm lenses on 1Ds or 5D bodies you'll need to fall back to the original EW-83E."
