My Nikon to Fuji X-mount Speedbooster on my XP1
The adapter is well built and made of good material. All the latches have a good feel. It also has a tripod mount on the bottom. If u do not use something like the Fuji Grip adapter, the tripod mount does not allow the camera to sit flush with the surface. It is designed to work w/ the new Nikon G lenses that do not have an aperture ring. In order to use older lenses such as the AIS, you will need to set the f-stop on those lenses to max f-stop (f16 to f32 depending on the lens). There is a number detent ring on the adapter with numbers representing relative f-stop values (both full and half stops).
It works as expected. My 35f1.4 is a 35 and 50f1.4 is a 50 again. You do gain that extra stop as advertised as well. A 1.4 lens becomes a f1.0 and a f1.2 becomes a f0.95. 0.95 is the max though.
Here are a some quick and dirty shots to show the effect of the speedbooster. Forgive the crappy scene, just something to show the effects of speedbooster. I forgot to reset the Fuji m mount lens adapter info between the 50 and the 35 mm lens so please ignore that photo info about the lens in the embedded jpg photo info. All shots were taken at approximately the same location.
Nikon 35f1.4 AIS w/o speedbooster 750@f5.6
Nikon 35f1.4 AIS w/ speedbooster 850 at approximately one stop higher aperture
Nikon 50f1.4 AIS w/o speedbooster 850@f5.6
Nikon 50f1.4AIS w/ speedbooster 750@ approximately one stop higher aperture
I was using the latest fw update. It turns out that in bright enough light the focus peaking was very usable compared to my testing late last night in my study.
Will try to get some shooting in with this setup during the next couple of weeks and try to post some pictures..
