I have the Lieca iiif red dial with an Elmar 3.5 and a Fison hood. I love it, but must say It's a little tricky to use.
-To set the shutter speed the camera must be wound on.
-Set the shutter speed dial, after being wound on, by lifting it and turning.
-There are two shutter speed dials. 1 for speeds from 1/25 to 1/1000 the other from 1/25 to 1.
-If you touch the top shutter speed dial when tripping the shutter you may affect the speed.
-To advance the film, while cocking the shutter, you wind the large knob.
-To rewind the film flip a tiny switch, located on the top plate and rewind using a tiny knob.
-Loading film requires either trimming the leader or fiddling usually with the shutter open, lens off etc. or some magic using a credit card.
-manually reset the film counter.
-You focus using the left finder widow and compose using the right.
-flash sync requires some intelligent manipulation of the ring surrounding the shutter speed dial. ( never done it )
-flash sync is 1/25 sec!!
-Remote shutter release requires an adapter.
-since I have the Elmar 3.5 and the Fison hood, I must remove the hood to adjust the f stops. Not removing the hood may get your finger on the lens glass.
In short, the camera is a real swine to use, if you compare it to say a Nikon FE.
But, it is a lovely little camera and if you don't mind a some archaic ergonomics you can actually do some nice work with it.
