Really interesting regarding DAS and EOTS capabilities:

The EOTS’s functionality consists of a TFLIR image, laser range finder/designator, laser spot tracker, and IRST,
as shown in Fig. 11. The EOTS uses low-profile gimbals with an optical system that maintains boresight accuracy
between the forward-looking infrared (FLIR) and laser functions. Precise stabilization of the EOTS’s line of sight is
achieved by gyro-controlled AZ and EL gimbals, and fine stabilization is achieved through a fast-steering mirror.
Equipped with a staring 1024-by-1024-element MWIR focal plane array, the EOTS is a dual-FOV system. The narrow
FOV is optimized for targeting functions, and the wide FOV is developed to maximize search performance.
So it seems like EOTS is technologically pretty much on par with latest operational podded targeting systems (save for SWIR and/or EO channels in some very latest pods) and clearly superior to any fielded fighter IRST system. Pretty impressive for built-in and fully integrated system.
Interesting things about DAS:
The program required a 360-degree spherical coverage missile warning system. The EO DAS consists of six identical
MWIR sensors distributed on the aircraft, each with a corresponding airframe window panel. The sensors are installed
such that their respective FOVs (95-degree AZ and EL) overlap to provide total spherical coverage. This EO DAS
subsystem provides the pilot with both an MWIR tracking capability and FLIR visual scene, but its FLIR is more
comprehensive. In legacy FLIR systems the pilot’s visual scene was limited to the forward sector. With the F-35’s EO
DAS, the pilot has a 360-degree spherical view of the environment. This allows for a true synthetic vision system, with
the image displayed on the pilot’s helmet-mounted display (HMD).
So this seems to confirm some earlier statements about 95-degree coverage by each sensor. Nothing about resolution though.
