Canon 85f 1.8 and 100.f2.8 are more suitable for taking wedding photos, but the effect of portrait {full body} is vague. Please compare them in detail.

First of all, the positioning of the two lenses is different. If you want to blur a portrait or wedding dress, you should choose 85/1.8. In contrast, 100/2.8 will be sharper but less fuzzy. Actually, the portrait doesn't need to be too sharp. The key is to make the depth of field too natural and feminine. In addition, to blur the effect, the nearest focal length should be used first, and then the aperture should be used, because the maximum aperture imaging is generally worse, especially the corner position of Quan Huafu.
