Does anyone know of a workaround to correct parallax issues when shooting tightly cropped portraits focused with the rangefinder as opposed to the ground glass. Im currently using a side mounted kalart rangefinder that admittedly needs recalibration to be accurate across all distances, but currently focuses perfectly at 6 ft, along with a Kodak 6 3/8" (162mm) lens. As I mentioned, everything is fine if I stick with a distance around 6 ft, but the portraits are not as tight as I would like. If I recalibrate for closer distances, the image is not centered in the frame due to parallax issues caused by the fact that the rangefinder is side mounted. I am hoping there is a workaround for this.

The speed graphic is relatively new to me so these might be stupid questions, but would simply using a longer lens like a 210mm or 240mm and calibrating the rangefinder accordingly solve the problem, or am I just going to have to settle for focusing on the ground glass when I want a tight portrait?
