Was excited but sad to say that I was left a bit disappointed. For context, I am using a Nikon 10x25 HGL Compact and cheapo Olympus 8x25 WP II. My wife has a Pentax 8x32 DCF ED, so I was able to compared them all back to back.I think the Nikon has me spoiled as the image is sharp edge to edge and the CA is very well controlled. The build quality of the HGL are top notch and the focuser is buttery smooth.The Zeiss 8x25 Terra has more CA and from center to the edges, there are irregularities in both the CA and sharpness across the field that leave me wanting. The edges are not as sharp as the Nikon HGL also. The focuser is rough and requires two finger adjust.Anyway, just wanted to share my thoughts. I was swayed into buying these by a review on another forum that waxed poetic on the Terra ED 8x25 and representing them as equals to the Swarovski 8x25 Pocket CL. Unfortunately, no free lunch here.Surprisingly, I preferred the Olympus 8x25 WP II Tracker to the more expensive Zeiss 8x25 Terra ED. I love Zeiss optics, but these are not where its at.</blockquote>
