I've found that a lens with less weight is great, but also a lens that can be short so that there can be more room between the lens and subject. So if there's a better option, let me know what that might be.

One thing that might help you in your decision process: Important for the available room between the lens and subject is not the length of the lens, but the working distance (measured between front of the lens and the subject). The TTartisan 40mm at 1:1 has a working distance of 3 cm, which is not so much; adding tubes or close up lenses to achieve 2:1 would shorten this working distance even more, making especially the lighting of the subject more difficult.

As a rule of thumb you get more working distance with longer focal lengths at the same magnification. If you're going for a good working distance at 2:1, maybe have a look at the Laowa 100mm 2.8 macro which provides you with a "built-in" 2:1 magnification, and still has a working distance of about 7 cm at that. Of course it's much more expensive than the TTartisan - but it would be a very comfortable solution. There is also a slightly cheaper, smaller and lighter 60mm 2x macro from Laowa out there that has a working distance of about 5 cm at 2:1.

Hope this helps!
