Hi all, yes the last time I had DAG add the third cam on lens for me it cost $100 USD. Dave I had the 'third cam' added to a 50mm Summi by Gerry Smith at Kindermann (Toronto). Can't seem to locate my invoice, but as I recall, it was about CAD$150 including shipping & taxes. An independent, like DAG, should be a bit less, and of course the cost will be lower in US$. The 21mm/f4 is a great lens, and will work perfectly with all your reflex cameras once 'tweaked'! Enjoy! ---------- David Young, | égalité, liberté, Victoria, CANADA | fraternité et Beaujolais.
