"The StarAF feature is awesome. Using the K3iii is a nightmare to focus because it has no flippy screen so to focus you have to get on the ground pretty much or have your tripod so high it can introduce flexure. StarAF means now I can trust the camera to focus perfectly, I have recently bought it for the K1 and will also get it for my two K1ii's. If you're reading this review and are maybe on the shelf, just do it, it is truly brilliant. Thank you Pentax/Ricoh, and please let us know when the new camera is due, just a vague next year will do. And DO NOT lose all the awesome functionality of the K1ii, and DO NOT make it MF (as rumours suggest) or I'm forced to leave the camp :( I need AF for my work, we need the AF from the K3iii (or better) put into the new FF camera. Don't let me down."

"I already have this for my K3iii and it is amazing, I now have bought this for my K1ii and can't wait for a new moon. The ability to focus without touching the camera on the tripod makes for such a steady setup, it is a brilliant feature, I am still a novice with the editing but Pentax has opened up an area of photography that I thought was out of my reach by allowing me to use my existing camera gear and some software, so clever. Thank you Pentax"

"It's too early, ( I write later at DPR under KPM2) because i use it only twice up to now. But one thing I can say at once: the Star AF is a great help and do work even if i myself nearly cant see that much of a star that i could manual focus on. Well done !"
