Hi everyone,
I have looked for infos on the forum (and I'm pretty sure I has been discussed here before but couldn't find it. Sorry if I double-thread)
I keep having the same focusing issue while shooting portraits at large aperture(f 5,6, 8 and 11) on a 4x5 field camera (toyo field) and a 135mm lens.
The focusing point seems to be often a foot in front of the place where I did focus on the ground glass. ( I focus normally at f5.6 on the ground glass and then stop down to the right F stop).
My ground glass is in right position and not reversed, I lock my focusing knobs correctly and everything, and I do take my time to focus correctly, using a loupe. And I have doubts it happens also with some sharp pictures I have, I just can't really notice it because of the smaller aperture (f32 and f64) and greater the depht of field.
I talked to some serious LF landscape photographers who had the same problem doing portraits at larger aperture like me, and didn't know also why and how it happened.
As a newcomer in LF photography, I seek for your help!
Thanks!
