I'm a photographer! No money to buy a macro lens! The lens I bought recently is not effective! I heard that close-range circulation is good! Have you ever used a soldier? Ask for advice?

1. I feel that the close-up shot used by LZ is very poor. LZ can look at the close-up of the treasure of photography, and the effect is very good.

In addition, the telephoto end plus close-up lens will be better.

2. If there are electronic contacts, it means that you can focus automatically and adjust the aperture. But like close-ups, there will be a focus limit after adding it. You can't focus beyond a certain distance, and you can't focus when the aperture is large.

Of course, if there is no electronic contact, it is manual focusing. In fact, macro manual focusing is very convenient, even if there is AF, macro also recommends MF.

Actually, focusing is not a problem. The problem is that Canon's current lenses are basically electronic apertures, that is, a connecting ring without electronic contacts is added, and the lens has been working at the maximum aperture. In this way, the practicality of macro shooting is greatly reduced because the depth of field is too shallow.

3. Same as above, it can work normally, just set it to lensless mode, but the aperture is not adjustable.

Give LZ two suggestions.

A. It is recommended to use a good close-up, such as the treasure of photography, which can be disassembled by itself and automatically focused.

If the connecting ring is added, there will be focal length limitation, which is troublesome to disassemble and inconvenient to use. In addition, if the machining accuracy of ordinary connecting rings is not high enough, the focal planes will not be parallel.

B. Give up the coupling and buy the macro head directly. Many cheap macro heads with aperture rings are 1: 1, and the effect is definitely better than adding extra mirrors/coupling rings to 18- 135.
