SLR camera lens with a magnifying glass before going to shoot macro, so there is no problem photography, right?
Ordinary magnifying glass are spherical lenses, and is a single lens does not eliminate the dispersion design, so distortion ah, aberration ah, scattered ah are more serious. Magnifying glass surface generally do not have any coating, reflective more, light transmission is not high ... ...

In front of the lens plus a magnifying glass shooting macro course is possible. In fact, this principle is a piece of lens mounted in front of the lens lens, but close to the mirror than the ordinary magnifying glass to work to some of the work.
Although this can be, but the ordinary magnifying glass will seriously reduce the image quality, and the higher the impact of the more serious; so it may choose to use optical experiments with high-quality lens or buy close-up camera is more suitable for taking pictures
