Humphrey,

The proper, original hood for the Summitar was a so-called 'barndoor' collapsible hood, Leitz code SOOFM. Very ingenious design, this hood can be collapsed flat when not in use - hence the name 'barndoor' hood. The hood clamps onto the Summitar and has a cut-out in its upper portion so that it blocks as little of the finder view as possible.

Not particularly diificult to find on eBay or in stores specializing in old Leica gear. If you're lucky, can be found for about US$30 - US$50.

The problem with the Summitar is, that it uses a special, conical filter mounting thread. That is why aftermarket screw-in hoods will not fit. Leitz used to make an adapter (code SNHOO), which would allow regular E-39 (39mm) accessories be mounted on the Summitar. This would include filters, as well as clamp-on hoods. Unfortunately, this adapter is scarce as hen's feet and would be even more difficult to find than the SOOFM hood.

Some of the later Summitar lenses had a groove in their outer filter mount, which would accept regular vented or non-vented E-39 hoods (IROOA or 12585). Those hoods use a clamping mechanism and often, if careful, can be used on the Summitars which do not have the groove.

I hope this makes sense - Leitz accessories and adapters are an immense subject. Leitz used to make adapters to adapt just about anything to anything........

Best,

Jan
