Vivitar 135/2.5 PK: 5 feet Zenit 135/1.8 MC Fodis-1K 5.2 feet" My Tamron 135/2.5 PKA Close Focus "officially" focuses at approx. 4 feet or 1.2m, but I just got it down to about 1.0 m. Geez, I'd love that Vivitar though, focuses down to 1.7 feet! Tanya. - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
