I've read some articles but I'm still not sure if this can work.
Your above mentioned lens 16-35mm from Nikon (AF-S NIKKOR 16-35 mm 1:4G ED VR ) has a magnification power of 1:4. This means that a bee of 2cm would have a size of 5mm on the sensor at the minimum focus of 29cm.
To reduce the minimum focus you can use such extension tubes which allows you to come closer to the subject and get a higher magnification. But to get 1:1 magnification (2cm bee = 2cm on your sensor) you would really need a long extension tube and have to come so close to the subject, that I'm not sure if you can handle this anymore. I've also read an article that an extension tube length above the focal length won't work. But I'm not sure about that.
So at the end I don't think, that you can really use your 35mm lens as a real macro lens. And even if it would work you would reduce the DOF in such a wa, that the background becomes much more blurry than before which means that you'll lost your desired effect.
But again... I'm not really sure if everything is correct what I've written and I've understood everything correctly.
