Macro photography of presbyopia

1. Relatively adjustable aperture ratio is better than non-adjustable. Look at your introduction, is it the kind of close-up ring between the bayonet and the lens you bought? If you can't adjust the aperture, it is difficult to balance the exposure and depth of field. Whether locking the maximum aperture or the minimum aperture will give you a headache.

2. There is no difference between true and false close-up circles. As long as the flange distance is increased, there will be a macro effect. Besides, this is not a precision instrument, so don't worry too much. But neither the contact ring nor the non-contact ring can focus automatically, and the function of the focusing ring is also very small. To a large extent, it is necessary to move the body back and forth to focus.

3. Don't worry. But I want to say that your situation is not suitable for the close-up ring. Because first of all, your lens has no aperture ring, and the invisible one can hardly be used; Networking is often not cheap. The enlargement of the second close-up ring is a bit exaggerated. If you shoot something as big as hg or rg, you may be able to shoot the whole body. If it's the size of mg, I'm afraid I can only take close-ups. Third, manual focusing is really troublesome. In fact, in this case, the close-up filter is most suitable for you, that is, the filter screw hole installed in front of the lens. The advantage is that you can use the camera as usual, and you can automatically focus on metering. The price of close-range filters is also rich and frugal, and the better the picture quality, the more expensive it is, ranging from a dozen to two or three hundred. Actually, more than a dozen will do. Compared with the troublesome operation of the close-up circle, the close-up filter is really convenient. I also have a close-up circle now, but I have a manual lens with an aperture circle from the last century, which I think is suitable and bold enough to buy, but I also think it is really troublesome to change the depth of field by exposure. If you use the close-up circle from 18 to 135, people will collapse even more ... so it is strongly recommended to use the close-up filter. Why not look it up on Taobao?

4. Whether it's the close-range ring, the close-range filter, or the anti-ring I didn't mention, the double-lens double-Yang docking equal-beat macro method, these are just alternative means when there is no macro lens. In other words, the macro head has the best picture quality and is the most convenient to use, which can't be compared with other methods. You will regret using the inverted ring upstairs, because the focusing distance is very close, the focal length is long and the viewing angle is narrow. In this way, you can only take a close-up of a chest image with the size of HG, and because the depth of field is too shallow, you may even be able to aim at the V-shaped antenna in the head, and your neck will be blurred, which is basically equivalent to a waste film taken by a model. If you can spend more than 2000 yuan to buy Longteng 90 Micro, you won't regret it. Of course, if you save some money to buy a close-fitting filter screen, the money saved will be enough to buy 2 or 3 sets of mg, depending on your choice.
