Went to the Saskatoon Civic Conservatory yesterday and tried out an old Sears 135mm macro lens. Mine seems to be an odd version of the lens as it has a macro zone but does not have the feared Ricoh pins, despite being labelled with PK. From what I read, Sears sold several variants of the lens so it could either be an odd lens or modified at some point. Either way it was fun and interesting to shoot with.
For those of you who live in Saskatoon and hate our cold, dry, and monotone winters, the Conservatory is a great (and free) place to find some warmth, color, and humidity. For years I have found a cup of coffee or tea on one of their park benches every week made January and February blahs go by a lot quicker.
