I finally loaded a Fuji Velvia 50 in the Rolleiflex SL66; the film insert is
easy to load, however you need to pay attention to the film paper back
position, the black internal side must look to your face when it is on the
pressure plate, in the other hand, the paper external side looks to your face
for the TLR. The SL66 film insert also has two rollers for the automatic film
feeler mechanism, but the film does not pass between them, it passes over the
upper roller. After you placed the film insert into the magazine, you use the
magazine button to advance the film to the number 1, you press this button
afterward and camera crank takes the film advance control; the sl 66 requires
to have the shutter cocked before to do any operation.Rollei developed the
first 6x6 SLR prototype in 1955, Reinhold Heidecke ordered the designers a
camera ergonomics familiar for the TLR users, this prototype did not advance
due to the Viktor Hasselblad/Reinhold Heidecke agreement, however when Rollei
developed the SL66 in the '60s the Heidecke idea was respected, this way the
SL66 has a focusing knob on the left side, a film advance crank on the right
side , a film feeler mechanism and a postion for the shutter release button
regarding the crank like the TLR and yes, you feel the SL66 very familiar to
use for us, Rolleiflex TLR users, except for the camera weight..
I will use the Sonnar 4/150 as standard lens for this film roll.Carlos
