>>3179636>>3179623Here's what my extension tubes can do while the lens is reversed. This is the kit lens that came with my D3400,

This is as zoomed in as the lens will go. I'm still waiting for the reverse ring manual aperture kit in the mail, so I was holding the reversed lens up to the extension tubes and holding the aperture wide open with a finger. I did some contrast, color, and tone changes in post. So these pics look as close to real life as I can get. I had to reduce the resolution in order to post though. Each is normally 6k x 4k pixels.
>>3179639The Nikon D3400 I have has a DX sensor (24mm x 16mm). I noticed in the descriptions of some FX lens they state the 50mm is 75mm equivalent on the DX cameras. How much would that effect things for macro?
