Hi, the Contax hood is very good and very well made. On its own it is 63mm deep, but you will also need a 67/86 step-up ring, which adds another 10mm or so to the depth. It's specifically designed for the CZ 300mm lens, and this is precisely what I use it for. The Contax hoods all have an 86mm diameter or larger, and all have to be used with a step-up ring, which can make them very intimidated on short lenses, but on long lenses it doesn't really make a difference.
You might also consider B+W and Heliopan metal hoods, which are also excellent, although the tele hoods may be a little short for you. --- Bob mailto:[EMAIL PROTECTED] Monday, April 22, 2002, 2:06:44 AM, you wrote: > How deep is the MH-RA67 metal screw-in lens hood? > I'm looking around for a screw-in metal hood for my Rikenon 300/4.5 lens > (67mm filter).
