Elpro Close Up filter/lens

Looking for help in trying to identify which Elpro close up filter (if any ) will give me a magnification factor of +10  ?

I know l can get a Marumi +10, but would prefer to go down the Elpro route if possible.

Thanks in advance.

"+10" is not a magnification factor. So what do you actually want?

I have the Elpro 3 and the Elpro 4  :  the Elpro 3 appears to give greater magnification than the 4.  I am looking to improve upon the magnification of the Elpro 3, but need guidance as to which Elpro l should be looking for.

You could stack the 3 + 4

Elpro 4 is +0.74 dpt  (f = 136 cm)
Elpro 3 is +1.64 dpt  (f = 61 cm)
Elpro 1 is +2.44 dpt  (f = 41 cm)
Elpro 2 is +4.76 dpt  (f = 21 cm)
Elpro 52 is +7 dpt  (f = 14 cm)

The magnification factors depend on the the combinations of Elpro plus master lens. For the same magnification, a shorter-focal-length master lens needs a stronger close-up lens (i. e. higher diopter number). To get higher magnification with a given close-up lens, use it on a longer-focal-length master lens. When stacking close-up lenses then their diopter numbers will add. Do not stack more than two. Screw the weaker close-up lens on the master lens first, then the stronger close-up lens on top of that.

Many thanks 01af.
