I'm sure at the highest setting it's really grainy and not that useful.
What's the highest ISO on the K-70, that still takes good looking photos?
Is B&Hʻs listing that the K70 has a max ISO of 204800, an error?
As others have posted, highest ISO "that still takes good looking photos" is subjective. Too many variables with RAW, jpeg settings, subject matter, and intended use. I understand your meaning, as yesteryearʻs ISO 1600 looks like todayʻs ISO 12,800.
Yes, with a max 102,400 ISO itʻs REALLY grainy and not that useful.....unless your flash is not an option and to get the best aperture and shutter speed trump pixel madness and noise.
As a shopper comparing DSLRs, I also look at the highest max ISO as an indication of that sensorʻs low light capability. In other words, I trust a K-70 that reaches ISO 102,400 will match the Nikon D7200 (max ISO 102,400) and definitely have a big edge over the Canon T6i (max ISO 25,600).
