Hi, a lot of members are older here, I am old too (73) but El Hank still has a big lead at 92. I have been working more than 40 years as an anaesthesiologist. I started with "medium format" Agfa Click, later I used a Rollei SLX 6008 System now again back at MF with a Phase One XF. My main camera as always been a Canon starting with a F1 in 1971, now with a 1 Dx III System. Not to forget a Sinar System with a Durst Laborator in the 90. So Now I am doing still life and nature photography and printing to my Canon IPG 1000 and 4100.
