When you stop down the lenses the performance improves but You dont use a F 1.2 lens to shot at F11, you put it on your camera to have that special dreamy, bokeh and narrow depth of field.
But what can be a motivation to prefer the one lens over the other. As always...it depends...
The handling of the lenses is quite different. The Fujinon with the autofocus, vs the CANON and TOMIOKA with manual focus.
This is mainly a review of the TOMIOKA but this is the chapter where my personnel joy of use with the TOMIOKA is at home.
The built quality of the lens is excellent and the manual focus feeling is on par with my best manual lenses.
Sorry FUJINON XF but in the chapter manual focus feeling the focus by wire of the XF56 is absolute crap.
The classic lens design at its best in combination with the focus peaking abilities of modern DSLM like the FUJI X cameras are for me the best of two worlds. I have nearly every FUJINON XF lens thats available in my bag but that "manual focus thing" is currently my cup of tea.
Not every shot is a hit, but the silent and smooth handling gives is a good qualification to play with the subject and the focus and find some compositions out of the normal focus point areas.
I tried the very expensive LEICA M, but sorry this is only the best of one world. The old manual world. The rangefinder is not able to give you that flexibility of a modern EVF. The M10 tries to compensate this with its new CMOS sensor and the back screen and the focus peaking there. But I like the approach of SONY, Panasonic, Olympus or my FUJI System more, to have a high resolution EVF and a classic approach of holding the camera to your eye and not with your arms 50cm in front of you, like the IPHONE Way.
But lets see some more bokeh captures wide open.
The series show the bokeh form minimum focus distance to near infinity.
