Question on using tele and wide in the Retina IIIc
Asking for operation help from Retina IIIc experts here.
I got locally a nice IIIc with the Longar 4/80 and Curtar 35/5.6, plus a Xenon 2/50.
When reading the manual I got confused about how to focus with the wide and tele lenses.
The manual says that, when using the wide or tele, you must first focus with the RF as you would do with the 50mm, and then transfer the distance to the scale in the wide or tele lenses. No problem with that.
But what happens with the focus ring after measurement? Should I keep the base focus ring at the distance measured, or should I set it back to infinity (besides, of course, setting the distance in the scale in the auxiliary tele or wide lens)?
For instance: Imagine that I measure a distance of 8 ft. I go to the scale in the Longar lens, and set it to 8 ft. But should I also move the focus tab of the camera back to the infinity position, or should I let it stay at 8 ft?
Second question. My Retina IIIc has two alternative distance scales at the bottom of the lens panel, one marked with a black triangle and reading in black numbers over chrome, and the other marked with a T and reading in chrome numbers over black. I gather that these are the scales to use with the wide and tele lenses, respectively. When using these, should I keep the scale distance in the lenses at infinity?
Thanks for any comment! I'd like to get over these doubts before wasting a test roll.
