Quote: after having been reading a bit in older threads I have found the existance of the tungsten light AF with fast lensen for many years. (also in other brands) Why should we expect Pentax to solve the issue all of a sudden with a firmware update ?
That was my point in my earlier reply. This isn't a Pentax only issue, it's an AF issue that has been around for quite some time. I would say there has been improvement, but it's certainly not perfect.
Quote: I think I might feel more comfortable with my CANON S95 indoors in respect of focus accuracy than with my expensive Dsrl right ?
Well, since the sensor size of the S95 is a fraction of the K-5, the DOF is going to quite a bit larger for a given aperture/FL combo. So regardless of how the AF systems compare in terms of accuracy (and the S95 might be more accurate, I'm not sure), the shots are going to appear to be in better focus with the S95 because the DOF is so much larger.
Quote: I think the industry will tell us to buy 2 camera`s . 1 set for daylight and 1 set for artificial light. Not a funny joke because this is the situation that we are all in at the moment if we would like to shoot troublefree in respect of AF. The whole hype around being able to shoot in dim conditions without using flash with the latest dslrs is down the drain if you cannot shoot wide open. It is better to shoot with max ISO 400 and 2.8 than with ISO 1600 and being forced to use minimal 5.6.
No disrespect intended, but that sounds a bit dramatic. First of all, you are free to change your AF adjustment for daylight/artificial light if you wish, no need for a second body. Personally I don't think that's a very good solution as I would tend to forget what it's set for and get myself into trouble. People in the past have suggested you could tie two different sets of adjustments to the WB selection. Again, not perfect, but potentially a step in the right direction.
An, for the record, the notion that shooting wide open is not "down the drain" or that you have to shoot f/5.6 to get in focus shots is simply not true.
