How much resolution is enough? (When should I stop caring if they add more resolution to new models?
Unless you think that you wouldn’t like a zero-weight, zero-size method of incrasing the range of your zoom lens, you should always be pleased to have more resolution. (See What resolution camera do I need if I want to produce prints of a certain size? above.) There are some practical issues to consider. While prices for storage are dropping very rapidly, you can saddle yourself with some expensive storage requirements if you buy a very high resolution camera, so be sure to budget for storage when shopping. In some cases, manufacturers will offer higher resolution models that don’t offer significant improvements over lower resolution models. This will occur when manufacturers push to get a higher resolution model out before they have mastered controlling the noise produced by the smaller pixels required for the higher resolution model. Be sure to read reviews carefully to make sure that the extra resolution you are buying isn’t coming at the expense of much greater image noise.
