I recently posted about my new 8.5x42 Swarosvski binocular purchase. Being blown away with them, I have now upgraded my scope to a Swarosvski ATS80 HD scope. Really superb scope in all respects, particularly blown away with the colour they pull in!
I purchased them with a 20-60 zoom eyepiece after several hours testing against the 25-50. My choice was down to a perception the 20-60 was sharper and easier to focus to the 'sweet spot'. Also I was worried at losing that last 10x of zoom for difficult to id birds at long range. However, a month later and I wondered if I had made the right choice, remembering the lovely FOV of the 25-50.
So I purchased the 25-50 after reading many good reviews on here, but after weeks of comparison my original thought was confirmed - the 25-50 seems to be more difficult to focus to that 'sweet spot'. Heat distortion also seems more apparent to me, leading to a satisfactory focus with the 20-60 but 'focus hunting' in the same conditions with the 25-50 zoom.
I wear glasses so could this be a factor in the apparent harder to focus succesfully with the 25-50? is there a technical reason why I am perceiving this focus difference?
I will sell one of the lenses, but am finding the decision difficult. The wide FOV of the 25-50 has lead to really great views of small birds close in because of the ease in spotting them. however, at further distances, like water birds at far side of a lake, the 20-60 zoom gives a perceived sharper image
