>>3350850Never used the 1.4 but from what I understand the upgrade isn't that necessary, the 1.2 is sharper at F2 and softer wide open than the 1.4. got it from a family member who moved to digital and it's a considerably nicer lens than the F1.8 I used prior.
Pic related is an example of a shot wide open with the F1.2. My grail OM lens is the 21mm F2 or 18mm F3.5
