When it comes to getting a great close-up of a bee, you’ll want to have macro capability on your camera. This could either be the lens you use with an interchangeable macro lens, or a camera with a macro function on it.
I use FUJINON lenses with my FUJIFILM X-T3, and currently have two macro lenses that I use: a 60mm macro, and an 80mm macro. The 60mm macro is only a 2:1 macro lens, whereas the 80mm is a 1:1 (true) macro lens. This basically means that the 80mm lens can focus a lot closer than the 60mm lens can. If you are serious about macro photography, I suggest investing in a true 1:1 macro lens to get the best quality images out of your gear.
However, with that said, because FUJIFILM cameras are crop-frame cameras, using the 60mm still gives me incredible close-up images. The frame itself is already cropped in due to the nature of the type of camera it is, so having a 2:1 crop ratio does not severely impact my photos. If you use a full-frame camera, however, you will see a greater difference in focusing distance than you would with a crop-frame camera, so the capability of the macro lens will be more apparent.
