Yeah! The Old Frog has found its way to PZ! One more manufacturer to spice things up a little.

The effect on the T vs f aperture isn't really described in the manual - it only says that you should use either aperture ring but not both in conjunction. The T aperture is stepless though thus this is the choice for movie lovers. 

 

I suppose in the very theory the T-ring controls the APD effect but at the end of the day it is also an aperture. I'm not sure why you really want to reduce the effect because that is the sole point of the lens. 

... Beside it being a high quality fast short tele lens? And the first one to stick it to the 5DSR sensor?

 

Also, my inner editor guy (after all, I have been working as an editor for almost 6 years!) has spotted a few typos.

Page 2, the Boken section:

"why Fujifilm didn't bothered"

Page 3, the verdict:

"but this one is a significant forward" (4th paragraph)

and

"Loawa" (5th paragraph)
