Fuji X-BW 35mm f0.95 16mp super IQ
May 12, 2012
I was thinking about the new Leica monochrome camera, which I can't afford, so I did a little number crunching and came up with this hypothetical monochrome fuji X camera I'd love to buy. I think it could be made and kept relatively affordable. Would you buy one at $500-$600 with high quality lens? I would love to hear your opinions
1/1.5 BSI EXR BW Sensor
35mm equivalent fixed lens
no anti-aliasing filter
14+ev dynamic range (with EXR)
Before you say the sensor stats are completely unrealistic there is method to the madness. I'll use the Olympus OMD E-M5 as a base for comparison as I think a BW 1/1.5 sensor would have a similar sized photosite sensor density and therefor similar performance potential.
As you can see from the math below (unless I made a blunder) the BW 1/1.5 sensor has a marginally better photosite density ratio then the colour Bayer m43 sensor. Therefor ISO performance could have similar potential to E-M5, Fuji EXR technology should offer awesome DR to the already impressive native e-m5 capabilities and no anti-aliasing filter will improve resolution with a good lens.
I'm sure I've had a few oversights, but that's my 2 cents worth.
1/1.5 sensor = 58.1mm^2
m43 sensor = 225mm^2
Colour Bayer sensor = R+G+G+B = 4 photosites per pixel
BW sensor = W = 1 photosite per Pixel
where photosite density = (photosite per pixel * 16mp) / sensor Area
Olympus OMD E-M5 sensor photosite density = (4*16mp)
= 284k photosites per mm^2
Fujifilm X-BW 1/1.5 sensor photosite density = (1*16mp)
= 275k photosites per mm^2
rounded to 3 absolute digits.
