What are the ways to use a small spittoon?

1, the aperture cannot be opened to the maximum, that is, 1.8. The larger the aperture, the higher the probability of virtual focus. I think this has something to do with the workmanship of our head. I usually use 2.8 at most.

2, if it can be put on the shelves, it is better to zoom in and focus with the real scene. It's practical to shoot products and still life in this way, but it's difficult to do this because there are fewer people outside.

3. Use the shutter as soon as possible. It is to ensure proper exposure, as large as possible aperture and high sensitivity to improve the shutter and reduce jitter. For high sensitivity, it should be noted that you can use it at will below 800, and use it with caution after it is higher than 800. If you don't care too much about dryness, it doesn't matter.

This head is a little different from other heads in focusing composition. Many photographers may also have the habit of focusing first and then composing, that is, swinging their bodies after focusing to complete composition. This spittoon should be used with caution, and it is best to make a composition before focusing. That is to say, it will be safer to choose the nearest point on the focus screen after the composition is completed.

This can be said to be the key point. The focus must be decisive and fast. First move the focus to a greater distance, then aim at the point that needs to be focused, focus at one time, and press the shutter quickly. This is also aimed at the characteristics of the spittoon, because the spittoon is not USM (ultrasonic motor), so the fixed point is slightly rough and not delicate and accurate enough. If you focus on the same point many times, you will find that it is sometimes accurate and sometimes empty. The practice is often to find the background focus, and then return to the fixed-point focus of the character at one time, that is, press the shutter. This film rate is still quite high.
