I will now be looking out for a filter holder for the Summitar from ePrey. Do you know if the collapsible Summitar II (the hex diaphragm model), uses the same tapered thread filter? I am guessing it does. I am surprised that the Summitar collapses, I thought only the final version Elmar 50 and the current Elmar 90 could do that safely but it is great news if it does. I agree about the "barn door" hood it is horrible. My father used to have a very nice little hood, which fitted on the outside of the lens. It was held on by a small knurled knob, which squeezed a crescent shaped pad on the inside of the hood but that disappeared when his IIIC got stolen in a car break in.

Hi Wilson,
I can't find any info anywhere that says the Summitar filter changed from the tapered 36mm thread. Fortunately the glass in the filter with the slotted retainer is the same diameter as the glass in the 39mm Heliopan UV/IR. I find the clearance between the collapsed Summar, Summitar and Summicron is at least 1/4 inch to the M8 sensor filter. But I still keep these lenses extended when mounted. I just feel better about it.
