I have the Meopta and they are brighter and clearer than my 2003 el’s. Never looked at the Maven, but can’t imagine them being better. I even find them better than a friends SLC’S.
I have the Maven 18x and they are outstanding on a tripod. My hand held pair is new version Swarovski SLC10x. I haven't noticed any depth of field short comings, and what actually sold me on the 18x was how large the depth of field was. I have not looked through anything Meopta.
