Hello, I currently have an Om2 with which I mainly use the 28mm 2.8 zuiko (I also have the 50mm 1.4). I’m considering changing the focus screen because the 1-3 that I have for now doesn’t necessarily suit me, you have to find a vertical line... it takes time.
After searching, I found the 1-1 and the 1-4 at affordable prices, but I can’t make up my mind because I can’t find any dedicated videos. The 1-4 seems very clear but I’m afraid the focus is not precise. The 1-1 is closer to the 1-3 by being simpler, but I read that it was less practical for the wide angle...
I’m a bit lost, hope you can help me :)
