Try recalibrating your micro focus adjustment...

I have a 50mm 1.4 for more than a year, but some focus issues have been happening more and more recently.

I have read a lot about focus issues on this lens in particular, but I wonder if this is something about the lens or about what I'm doing.

Any tips? I feel do frustrated when this sort of thing happens and it has been quite frequent lately.

Thank you!

I took some shots with my 50 1.4 today and noticed how badly front-focused my shots were (very similar to what you've gotten).

I had previously set the camera to us a MFA value of -2, tested under a number of situations where I had consistently good results.

Today, I had to use a MFA of +8 on the lens to get shots in focus. My lens was never dropped or subjected to any abuse and I have no idea why the lens all of a sudden changed its calibration so much. Perhaps it's the temperature change? Humidity?
