The K-01 doesn't have TAv in the mode dial, but it still has this shooting mode! Just go to M, set the aperture and shutter normally, but unlike the K-r, you can choose auto ISO (the K-r allows that in Av and Tv, but not in M). Even the text on the screen changes from M to TAv. So this is pretty great, I think a lot of people don't know about TAv on this camera because they don't read all the specs and it doesn't appear on the mode wheel in photos. So, just letting you all know, because a lot of you love TAv
Does anyone know, though, whether it is possible to set exposure bias, or will the camera in this mode always go for "0"? Is it possible to (on purpose) take an overexposed photo in this mode, or will the camera always automatically lower the ISO?
