>>2889345I had a prism but the moment I got a WLF I never put it on again. Do you have a split focus screen in the camera? I find that more than adequate to hit critical focus when using the WLF. Is this your first experience shooting with a WLF? After awhile you'll get the hang of it and will become surprisingly quick to focus (assuming you have a split focus screen).
>>2889345This is a nice shot by the way,and I completely agree with your sentiment. For 100 speed black and white there's no substituent for Acros.
