I have a Pentax K1000 for over 10 years and have been very happy about it. Last year, I bought a Pentax LX, based on peoples comments that it is the best SLR in the world. However, I have had headache since I received it. It had various problems and I sent it out for repair twice. Now the repair cost exceedes the camera value and I have mixed feeling about it. I keep thinking about my trusted K1000 and wondering why this camera, costing a fraction of the LX, behaves much better. I did a little search online and here is my summary. K1000 and LX are about the same size (143x94x50mm vs 145x91x50mm), but K1000 is heavier than LX (606g vs 565g). How could LX put that much more feature into a much lighter body? There are only two solutions: use more plastic parts or make the metal parts thinner. Either way, reliability is compromised. I know there are many lucky guys here who will tell me that their LX bodies have never given them any trouble and I am just an unlucky person, but have you done statistics? Does anyone know the defect rate of the LX?
