I have a 45/4n lens for pentax 67II. I read on the manual that the dedicated pentax hood and the polarizer filters cannot be used together (may be vignetting occurs?). I wonder whether hood can be used together with normal screw-filters(yellow, red, etc.) without vignetting. Is there anyone who can comment on this question? Thank in advance to everybody. Giovanni

I have the earlier Pentax 6x7 and regularly use the 45 mm f4 lens with a screw on yellow B&W filter and the Pentax lens shade with no vignetting. In fact, that lens shade offers quite a bit of room according to my tests.

Erik, thank you for the kind answer. If I have well understood , the pentax hood is a bayonet which fits into the inner threaded part of a commercial, non pentax, screw filter. Is this the case? Thanks again Giovanni

Giovanni,

Yes, you are correct. The bayonet hood has buttons you push in, stick it on the filter, and let go, and it stays. Note that this lens hood really only provides the most minimal of protection from flare because the lens is so wide. It is a terrific lens though -- I use it a lot and it is superb at all apertures.

I sure wish I lived in Italy. What a fabulous country you live in. The pasta. The architecture, the gelato, the tomatoes. Oh, if only I could find a way . . . !
