Ethos 110º
Yesterday finally managed to look through an Ethos ep and it was a double experience since could test 2 Ethos.
One was a 17mm but this one cann't be used in a spotting since is a 2". However the result was great http://www.birdforum.net/showthread.php?p=2439117#post2439117
In my Optolyth100 I could test the 3.7mm after testing the 17mm. In this ep the AFOV is 110º and after the good surprise of the AFOV I could use with glasses on the 17mm (about 90º!), I was completely disappointed since only could see <50º AFOV on this ep with glasses...:-C
My interest is the 4.7mm (the 3.7mm result on too much power with the 630mm of the Optolyth 100), but don't know if has better useful eye-relief than the 3.7 version. My expectations decreased a lot!
