"Has anyone tried to put a close up filter on the 300/.45?" This amusing typo (the lens would be over 2' in diameter!) got me to thinking... I've read that the maximum lens speed possible in air is f/0.7. However, I've never seen an explanation of this limitation. Does anyone know the reason? < This message was delivered via the Olympus Mailing List > < For questions, mailto:owner-olympus@xxxxxxxxxxxxxxx > < Web Page: http://Zuiko.sls.bc.ca/swright/olympuslist.html > |
