What lens is used for Taobao photography?

Personally, I think there are several reasons why your photos are not clear enough:

First of all, you should take a full-body photo of the model on location with a 24-70 F2.8 lens, not a 70 lens. The imaging clarity of the lens on this focal section is weak. Whether it's a few hundred pieces of 18-55 or a 24-70 with a price of nearly 10,000 yuan, the imaging quality of the zoom lens in the middle focal section is basically higher than that at both ends, and the imaging clarity of the focal section of the 24-70 lens between 35 and 50 will be the best, with little deformation. The best aperture is between F5.6-F8 and F8.

Second, if you shoot 70 models, you will be far away from people. Under the same aperture and shutter, the longer the focal length, the lower the definition and the shallower the depth of field. This is the basic law. But it is not recommended that you take a full-length photo of 24 ends. This kind of focusing lens will not have the best definition and poor edge imaging.

Third, you need to pay attention to the camera shutter speed when taking pictures with Av files. It is best to stay outdoors for more than1100 seconds. If it is not enough, the sensitivity can be improved appropriately (5D2 has excellent imaging below ISO 800). When I use a 60D camera, I often set the aperture shutter manually with M gear, and the sensitivity is set to automatic. Just pay attention to the exposure instructions when taking pictures.

Fourth, the camera can try to take pictures in RAW format and set the appropriate sharpness later. When taking pictures outdoors, use an aperture around F8, so you don't have to pay too much attention to the focus. Basically, you just need to focus on that person. Try not to use the focus point next to 5D2, which is inaccurate. When I saw the photos taken by others, my eyelashes were all rooted, and many of them were taken at 50 or 85 fixed focus. The 24-70 lens is an old lens, and its sharpness is not good. Compared with fixed focus, there is indeed a gap. If you still can't reach the ideal clarity after paying attention to the above points, you can borrow 50 or 85 heads to try.
