•The effective focal length of the dioptere are:
• +1 = 1000mm
• +2 = 500mm
• +3 = 333mm
• +4 = 250mm
• +5 = 200mm

Didn't really use that much before I bought a close-up lens. No comparison between the two really. The filters get you closer, but a whole lot. Best if you don't want to tote another lens.
