I know I am going to tick alot of people off when I say this but I was just sitting on my back patio this afternoon looking at some of the Hummers at the feeders. I had the Ultima DX out along with a Swaro SLC. Now don't go thinking I am going to say they are similar in image quality. Overall they aren't as the Swaro has an almost perfectly flat, distortion free image in comparison to the Ultima DX. However, apparent centerfield sharpness on the DX appeared to be at least as good as that of the SLC and the DX had a more neutral overall image in terms of color representation.I would be cautious of published ER figures. They are not always accurate for a variety of reasons. I was just reading a thread in the Zeiss forum recently where Zeiss listed all of their FL binoculars as having 16 mm of eye relief despite the fact that consumers have found varying amounts with the different configurations. Having said that I did just pull out both my 6x and 8x Yosemites. The 6x does offer slightly more eye relief. I know this simply because when I press my face firmly against the eyecups of the 6x model I begin to see the image start to blacken out around the edges. I do not get this with the 8x model when I attempt the same procedure.FWIW, I get the same result (no edge blackout) with the 8x32 Celestron. Without actually measuring both I would say that the eye relief on the Celestron and the 8x Yosemite is very similar. I prefer binoculars with significant eye relief not because of wearing glasses (I do not) but rather because of the shape/size of my nose and inset of my eyes. Certain bins with short eye relief and wide eyecups (Nikon E2 for example) are unusable for me because of this. I do not have this problem with either the Celestron or either of the Yosemites. This may or may not be helpful in your situation but I thought it something worth mentioning.</blockquote>
