15Mm Heliar on the Bessa R

[cosmonaut]

I have a Heliar 15mm that I am wanting to use on my Bessa R and also my Leica IIIa. But the lens isn't focusing. It doesn't appear to be pushing the focusing roller down. Almost like there is a part of the lens missing. Is the 15MM for the Bessa L only and can I get an adaptor to fit it to an M series camers. Thanks.

The 15mm isn't rangefinder-coupled, so you have to guess-focus it. But its depth-of-field is so great that you just set it on the hyperfocal distance and shoot away.

There's no rangefinder coupling with this lens. I practice you don't need it - just guestimate the distance and the huge DoF will cover any errors.

Sorry, missed that bit - yes, any LTM to M adapter will do (but it still won't be coupled to the rangefinder)

Thanks again. Since the IIIa is hard to focus I guess the 15mm has found a permenant home.....

It is a good idea to get also suitable VF for the Heliar 15 mm

Amazing lenses these wides ... the Heliar even at f4.5 has an enormous depth of field.

Bokeh is very hard to achieve!
