Zeiss Relic Vibe, Ikonta 521-16

Tested a bl;ast from the past this AM  on Honlulu in good ol'Montrose, CA.  Ikonta 521/16 is  medium format camera (6 x 6 negatives)  and its 100% manual, no lite meter, no auto focus, only focus help is dsitance scale on the lens barrel.  Shoot with Arista 100 which I like very much.  Here a some of the photos, camera works, used zone focusing and a tape measure, need to p[erfect my skills with zone focusing.  Camera is joy to use and negs are good size.  What do you think??
