I understand what your saying here about the AA filter that's great info to know but saying it will ruin a photo without the filter is a little over board here, im sure there's more to a photo than just a filter pass, it's good to have it if one can but it's not that serious. so many great images out there without this filter in camera's but I get your point here on the advantages of having one in the camera. Thanks.So I guess my question would be why would there be two versions what are the advantages of each I confuse easily Thank youIf the objects in focus in the image NOT have straight lines, and has NO repetitive geometric shapes, the AA filter is not required.
A camera with no AA filter, using a high sharp lens produces images that can be printed in very large sizes while maintaining sharpness. But objects like fabrics, screens, grids, and other highly subject to moiré can ruin a photo without AA filter.
