Metabones EF to M43rds Speed booster ultra

I had made an attempt to test the Metabones speed booster in the past. But that was with my Stock EM1.

 

This time I used the Pentax UAT 85mm f4.5 lens, set at f5.6 to test if there was an effect on the UV transmission with the Speed booster.

 

UAT only using 390bp25 filter:

F5.6, Iso 200, 2 seconds for good exposure.

 

UAT plus speed booster lens set at F5.6, ISO 200 the same exposure was 1.3 seconds. So slight improvement.

 

UAT only using 370bp15 filter:

F5.6, ISO 200, 4 seconds.

 

UAT plus speed booster lens set at f5.6, the same exposure was at 4 seconds. So no gain in light, but there was a gain in field of view, and loss in depth of field.

 

UAT only using 340bp10 filter:

F5.6, ISO 800, 20 seconds for good exposure.

 

UAT plus speed booster lens set at f5.6. The image was black, No UV through. So this is the limit.
