Most modern digital SLR cameras use matte focus screens with their autofocus systems instead of the split circle manual focus screens found in non-digital SLR cameras. Although not factory endorsed, there are replacement manual focus screens which can be very expensive. Reader [Jan-Erik Skata] decided to save some money by salvaging the focus screen from a Miranda dx-3 film camera. Removing the screen proved extremely difficult and the Miranda would have been a total loss if it had been functional. Once out, the screen was sanded down, cleaned and then placed in a Canon EOS 300D. It’s hard to take a picture of the screen through the view finder to prove that it works, but I’m sure Jan-Erik is taking some great photographs having completed this upgrade.
