It can also take pictures with lower resolution like 4240 x 2832, 6000 x 3376, 4000, x 4000, 4240 x 2832, 4240 x 2384, 2832 x 2832, 3008 x 2000, 3008 x 1688, 2000 x 2000 with 1:1, 3:2, 16:9 aspect ratios. Pentax K-5 IIs is equipped with PRIME II processor and can take pictures up to 4928 x 3264 resolution. It can also take pictures with lower resolution like 3936 x 2624, 3072 x 2048, 1728 x 1152 with 3:2 aspect ratios.

Lens Mount

Fujifilm X-E3 has Fujifilm X lens mount and Pentax K-5 IIs has Pentax K_AF2 lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.

No Low-Pass Filter

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on either of the cameras. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Pentax K-5 IIs

Pentax K-5 IIs has a built-in Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.
