BORG 107FL F3.9 for 55mm Diagonal Sensor

This is to re-write my previous blog. I wanted to review how BORG 107FL F3.9 performs with 55mm sensor camera since I’ve never owned such a big sensor camera (too expensive to me!). But I recalled I got some shots before. This was one of them.

The above was taken with Simon Tang’s Fuji GFX camera 3 years ago.

We can see some meridional coma at each corner. But this is what expected. As my personal opinion, I’d like to express this still works very well particularly “at this speed=F3.9”. In general, it might go better if we re-tune the distance longer within 0.2-0.3mm range.

This image also shows the proof for the full frame sensor.
