Nagler 4.8 vs 5mm ? differences

What is the difference between these two EPs. Big price difference!

thanks howard

Howard, I used to own a 4.8 (Type 1). My complaints were that it was a little soft sharpness-wise, and the eye relief was a contradiction in terms. Never compared it with a 5mm Type 6, tho (don't even know anyone that owns one!). But I think I've heard that the 5mm Type 6 is better WRT both shortcomings.

I've since replaced it with a 5mm Radian and never regretted it.
