what about focusing with the C-Biogon 21 f/4.5

[italy74]

Hello everyone

unless you have a Bessa R4* which is the only one framing for 21mm lenses, how do you feel focusing with such wide angles (on film) on a Zeiss Ikon?

Is estimate focusing - relying only on lens marks - accurate enough ? Of course external viewfinders can encompass the angle of view of the lens but not tell you where you're focusing.

Thanks.

The lens is rangefinder coupled:
The idea is to frame with the external finder and focus with the cameras internal rangefinder.
However as the depth of field is large, and frequently the focus distance is set to fall within the depth of field marks encompassing your subjects closest and furthest distance, you may not use the internal rangefinder very often.
