I got the CL 10x25's and I find the eyecups come up a little short. My eyelash blacks out and I find myself holding the top of the eyepeice against my eyesocket while the bottom is out and exposed to stray light.
I already did my practice run for how to mod the eyecups a little longer with no damage to the binocular. I'm modding them for sure. I had that perfect circle with black around it and my whole eye in the cup comfortably. I 'm getting sick of holding glass a half inch from my face and wish these very expensive manufacturers would get their acts together, this happens constantly to my bins except the FL10x42 and 8x32. Wouldn't surprise me if Zeiss made their new conquest line a bit too short.
All Zeiss Victory FL's have 16mm eye relief if I'm not mistaken, and if they are like my 7x42 they also have very large and wide eye cup rims and I think that also makes a difference in helping out in eye placement.
The eye cup rims on the 8/10x25 CL Ps are really quite small and I think that is why I find the 8x30 CL easier for me to use than the the 8x25 CL P which has 2mm longer ER than the CL does. They are also larger than the eye cup rims on the discontinued 8x30SLC although the ER is the same and here I also find the 8x30 CL easier to use.
