The latest acquisitions to my Olympus Camera collection: An OM-3 black body, Pen FT, two OM-4s and a couple more Zero Halliburton cases to house them

In my third Zero Halliburtion case I have placed, right to left, front to back, my OM-3 black body, OM 50mm f1.4, Pen FT w/38mm f1.8, OM 75-150mm f3.5, set of 72mm filters, OM 28mm f1.8, Vivitar 55mm Macro, and in back a spiratone 400mm f8 I got with one of my OM-4s.

   In my fourth Zero Halliburton case I placed, left to right, front to back, my first OM-4 black body, OM 55mm f1.2, second OM-4 black body, Tokina 26-85mm f3.5-4.5, two sets of 49mm to 72mm step rings (they allow installation of any one of the 72mm filters to any lens I have for all OM bodies), a complete set of 55mm filters for the 55mm f1.2, 55mm metal lens hood for 55mm f 1.2, a OM Winder 2, and a OM T-20 Flash.  Sitting loosely in the back of the case is a set of 28mm filters for my Pen FT.  They include 3 ND filters, an Olympus close-up, and a circular polarizer. 
   I am planning to aquire yet another Zero Halliburton for more lens and accessories.  Extra lenses thus far include a Vivitar 17-28mm Zoom lens, a Sakkar 35-200mm f3.5 Zoom.  Also I have acquired an OM T-32 Flash, a Vivitar 283 Flash system, a Hanimex Pro 550 bounce flash/grip system.  I also managed to aquire an Olympus Varimagni right angle finders for both the OMs and one for the Pen FT.
  And finally, I managed to acquire a OM to Pen lens adapter that will allow my to use all of my OM lenses on the Pen FT which will eliminate the need for buying any more lenses for it.
