Ah now it makes sense. To me a 500 lens is 500mm and a 1500 lens is 1500mm I agree that there is not enough difference to pay an extra 1000 /$ or whatever the currency is. There is also some confusion in general as the definition of noise and what is actually posterization, which if I remember correctly was discussed in a thread 3 or 4 weeks ago. These two things are different. Noise is usually red green or blue artefacts in a jpeg whereas posterization is blockyness in an image see link
