It appears that the Fujifilm X-H1 AF system isn’t any faster than the Fujifilm X-T2 or X-Pro2 according to Fujifilm.
“We’ve mentioned previously that the AF speed will not be any faster. The key now is to expand the area that the phase detection AF can cover. This is true also for X-H1.
Has the AF gotten faster further more?
Many X-Photographers who have tested the X-H1 commented that “the AF is faster”. But the fastest AF speed has not changed. What’s been changed is the area that Phase detection AF can cover. The new algorithm helped the photographers to accurately capture the scene that they wanted to capture”
Many photographers felt that they Fujifilm X-T2 AF system was faster than the X-Pro2 when it was released, but Fujifilm cleared up the miss understanding quickly. It seems that Photographers confuse complex focus acquisition with focus speed and this is why the Fujifilm X-H1 ultimately feels faster when focusing than the Fujifilm X-T2 and X-Pro2.
“The X-H1 has maximum of 325 AF points (13×25). If speed is your priority, it is best to use the phase-detection area of 169 points (13 x 13) at the center….The focus point is detected by using the phase detection pixels found within the AF frame. At the default AF frame size, there are 20,000 phase detection pixels within the frame. The key is how to extract the useful information to improve focusing. This is where the new algorithm is implemented.”
Since nothing about the new algorithm is physical it could easily be included in a firmware update for the Fujifilm X-T2 and X-Pro2, but Fujifilm might treat this new algorithm like they treated the advanced tracking settings with the Fujifilm X-T2 vs X-Pro2. Fujifilm even gets into how their new algorithm works a little bit in their new X-H1 Development Story #6 -Autofocus post, but the numbers aren’t overly informative. Read More
