>>3336283>To get past 1:1, with a normal macro lens, you need to make your own ridiculously long extension tubesActually, if it's a proper macro lens, any length of extension tube immediately puts you past 1:1 because it was already capable of 1:1 [in a few instances more than that] before the extension tube.
But generally you're right, getting to 10:1 on a ~90-105mm ish typical macro lens with an extension is certainly going to take a silly long extension tube.
And I'll add that the result will not only be too narrow in DoF for almost any use, but also look extremely shit [sorry, no lens has that kind of resolving power] plus providing enough light so it's not dark will get very tricky.
The thing to actually do is just take a very sharp macro lens & a current large pixel / "low light" 24MP FF camera [or a 40-50MP one, but generally large pixels are better due to diffraction issues when you pick a narrower aperture to get some DoF], extend to at most 2:1 or something and then digitally crop until you got "only" 4MP or some such left in your photo. It'll probably still look good enough, but it's now zoomed in a lot.
Maybe even do the same with a digital MF camera, but I guess you'd have to be a very serious hobbyist or a professional or pretty wealthy to justify that expense - [it's well beyond a typical middle class impulse buy price range].
