Leica is in a unique position in the digital photography world as it is the only camera company which uses both an ASIC chip (Maestro) and an FPGA chip (Xilinx) in its architecture. The principal advantage of an FPGA chip is its versatility - it allows programmers the ability to modify and upgrade entire program modules, something that cannot be done with an ASIC chip. If the (Sony or TowerJazz) sensor used in the Leica SL2 does support PDAF (and hopefully it does), Leica could presumably reprogram AF related modules in the Xilinx FPGA chip to include phase detection. I realize this is a long shot, but hopefully we should know more within the next 12 months. Let's keep our fingers crossed ... Link to post Share on other sites More sharing options...

caissa Posted February 11, 2020 Share #3 Posted February 11, 2020 (edited) Exactly, there needs to be physical support for that. So that cannot be added by software alone. But Panasonic is also working on a new much better version of AF (ToF AF). Maybe it comes with the next generation of cameras (or the one after that). Some smartphones already use this ToF sensor based technology. Edited February 11, 2020 by caissa Link to post Share on other sites More sharing options...
sillbeers15 Posted February 11, 2020 Share #4 Posted February 11, 2020 PDAF uses hardware (Dedicated sensors on the same plane as pixel sensors) to translate Into AF algorithm for the lens micro motor to move optically in focus. It is already what it is. As for CDAF, it is algorithm based using image reflected by pixel sensors, it has come a Long way and improvement on speed and there is still improvements ahead. I would expect overtime for CDAF to supersede PDAF in speed. As for precision, CDAF is already more superior. Therefore most mirrorless cameras use a hybrid of PDAF+CDAF on their AF system. Only Panasonic uses CDAF. Link to post Share on other sites More sharing options...
caissa Posted February 11, 2020 Share #5 Posted February 11, 2020 (edited) Some rumors about ToF AF, https://www.43rumors.com/ft5-panasonic-is-developing-a-new-tof-micro-four-thirds-sensor-for-a-new-perfect-autofocus-system/ The holy grail of autofocus. 🤓🧐🤔😂😎🐣👍 Edited February 11, 2020 by caissa Link to post Share on other sites More sharing options...
