Originally posted by ebouwens What I'm wondering is , do either of you have experience using the Pentax K series in low light, and how well does it latch on in difficult conditions? I'm considering renting one for a weekend and giving it a try, perhaps with a 31 mm FA 1.8.
The K-5 ii and K-3 have the best low-light sensitivity on the market. That means that they can operate their AF in conditions where other cameras won't be able to. So this is clearly a perk for your intented purpose. What's more, even though AF is not as quick in low light (obviously) it's still more than ok. I believe the K-3 would serve you well for your intended purpose.
