thanks for the replies guys,
I have yet to look through them and compare them, I am a beginner and contemplating upgrading my bintel standard plossls, but then i came across these and thought I should find out what they are before I spend anymore money.
When I get chance I will compare them to what I have, what is "field stop"? is that clarity at the edge of the field of view?
Many thanks again to all who have replied..
Cheers
Steve
