My Sigma 170-500 in Nikon mount is a bitch to get on a tripod. Its the battery compartment on the D1, D1H and D2H that get in the way, using the lens collar.
I found a work around, but i use the lens so infrquently, i forget what i did,:-) Dave -- Documenting Life in Rural Ontario. www.caughtinmotion.com http://brooksinthecountry.blogspot.com/ York Region, Ontario, Canada -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
