The dynamic range of the Pentax K70 is just another example of the excellence of this APS-C sensor camera. Using the Pentax DA 18-135mm WR lens, I took the K70 into a little small town alley near my home just before dusk. You can watch my Youtube video below, or view the images in the gallery as well.
Shooting only handheld, I was able to get some very unique, colorful night photos with 3200 and 6400 ISO, and typically shooting at 1/60 or even as low as 1/40, with the lens wide open on the aperture (f/3.5 or f/4).
While there is noticeable noise in the sky portion of the images, which can be avoided using a tripod and low 100 ISO, I find that for social media, and other non-print or non-professional needs, this works fine. I enjoy the exploring and moving around more than standing still with a tripod. Though I've used a tripod extensively over the years with great results, I tend to prefer to be on the move lately. But you have to have a camera that can handle that, like the Pentax K70.
