    The AX100 can encode a 4k stream in high-end h.264 (AVC S) to an SDXC card so there is no problem with the SDXC card or h.264. Encoding in h.265 is significantly more compute-intensive than encoding...

    Best personal product of the year is the Sigma 50mm f1.4 Art lens. The image quality coming out of that lens is unbelievable, and the price can't be beat.

    B looked better all around. A has significantly less resolution, you can see it in the trees even though the scene itself is not particularly challenging for detail or dynamic range.

    The minimum exposure for the camera is three time slices. Imagine you're taking a picture when a flash goes off very briefly, just enough for the first time slice. Then all the pixels sampled in the...

    Aliasing is a more general phenomenon. Moire is a type of aliasing that has a spatial characteristic.

    Well, for one, if the sensor could really measure all three color values over the full shutter speed then it would capture significantly more light (eg. 3x) which means much better low light...
