I had a 2.5-10x56 Klassik but mine was the Illuminated #4 (L3) and was very good in low light. The illumination is a nice feature especiallyif your hunting in low light situations. I ended up selling it and shouldn't have. I have now since bought a 4-16x56 Polar with same reticle after several chats with Bobby Tomek on the site. Its the best slow light scope that I've ever owned or looked through. But it is much more expensive than the Klassik.
