It was back in 2002. Our older daughter (at the time the only child) was just about 1 year old. Simple point and shoot camera won't do it. So my wife and I embarked on "which SLR camera to buy" journey. I don't remember why, but Canon was out of the question. Perhaps due to price issues. The ultimate choice was between Nikon F80 and Pentax MZ-5. I remember that we downloaded the brochures from the web (oh yes, it was already possible at that time
). And although the actual number of controls was the same, it seemed as if Nikon has twice as many. So we chose Pentax. At the last moment I found about MZ-6 and went for it. I remember the process was properly long and mentally excruciating. My wife did not shoot too much with any of the cameras that went through our household since then.
So, in principle, we (I?) chose Pentax totally at random.
