I did not use much my Pentax gear since this 2018 trip to Peru.
That was the last time K3+DA 18+135 has been my main camera when traveling abroad:
I now rather use my M43 gear when traveling: 3 bodies (GX8, G7 and GM5), 3 f3.5-5.6 zooms (12-32, 12-60 and 14-140), the tiny 35-100 f4-5.6 and 3 f1.7 primes (20, 25 and 42.5).
My K3 gets still some use when photography is the main purpose, but when traveling with my new girlfriend, my Pentax gear is just too big and heavy. I have also enjoyed the odd angles framing that mirrorless allows, be it from low or ground level or above my head when in a crowd, or in museums.
Yet, after now 2 years using mainly M43, I admit that the Pentax overall rendering, contrast and dynamic range is better, and the DA 18-135 checks these points: I can use my Pentax out of camera JPEGs with minimum post processing, whereas my M43 photography needs more post-processing, more often discarding the OOC JPEG and developing the RAW file to get the kind of 3D pop I get directly from OOC Pentax JPEG.
I hope Pentax will add a mirrorless light camera body to its offering, next year or in 2021.
