The Sigma fp L expected to be announced soon, but with a weird (not Foveon) sensor
The Sigma fp L was thought to have been getting announced at CP+ last month, but it turned out to not be the case. Instead, we just saw the new 28-70mm f/2.8 DG DN Contemporary lens for Leica L and Sony FE mounts. Now, though, a Tweet from Nokishita suggests that an fp L announcement is imminent. They say that an article with the title “SIGMA fp L First Impressions” has been added to a site that has previously reviewed the 28-70mm mentioned above.
L-Rumors, though, has heard another rumour from a couple of sources suggesting that the Sigma fp L will see a very weird looking sensor. It’s not a Foveon X3 sensor, as it still shows individual photosites for each of the red, green and blue pixels instead of stacking them on top of each other for every pixel. But it looks very much like the old Fuji Super CCD HR sensor from their DSLR days.
The new sensor is said to be a new Sony sensor, named IMX513BQR with an “effective 60.75 megapixels” resolution that has a 30-megapixel mode which is allegedly the same quality you’d expect from a Foveon X3 sensor. Except, with presumably the benefits of a more traditional CMOS sensor – like decent ISO performance and speeds capable of more than a couple of frames per second.
About the rumoured sensor, the L-Rumors source says…
The newly CMOS sensor of sigma fp L has a CFA like the fujifilm’s Super CCD. Sigma get a customized full frame 61 megapixels no-LPF BSI sensor with zig-zag manner pixels and 45° rotated bayer color filter array, which pixel design based on sony-semi’s most popular 3.76um Exmor R series.
This special pixel array was name as “Q67” or “ClearVid” in sony’s speech, was used in F65RS cine camera.
This 61 megapixels zig-zag pixel sensor can output 30 megapixels green channel image without any interpolation and color the picture like the Foveon X3 Quattro. So it can be the flat version of Foveon X3, but save the high ISO.
In additionally, this customized sensor use the same color filter as the PhaseONE IQ3 100MP Trichromatic. It has the best color reproduction even better than the old Foveon X3.
Nokishita has also said that a number of accessories – presumably for the fp L – have been added to Sigma’s accessories list.
- EVF-11 – Electronic Viewfinder
- EC-31 – Eyecup
- EC41 – Large Eyecup
- VC-07a – Semi-Hard Case
When I found out that Sigma was set to release another non-Foveon body, I was prepared to be somewhat disappointed. But if the rumour of this sensor turns out to be true, then it’s pretty intriguing. So, it will be interesting to see if the fp L does contain such a sensor and I’d really like to see it for myself at some point, particularly its video capabilities.
