Is this the Heliar 75 you have?

It looks like it doesn't really stick into the body at all. Perhaps the adapter does a bit, but not beyond the mount flanges I guess?
The problem with lenses which stick deep into the body is that they can interfere with the lightflow to the sensor. Normal and tele lenses don't usually have problems like this.
