Message: <blockquote data-quote="Rathaus" data-source="post: 3279868" data-attributes="member: 132018">Though the conditions are still hazy, I set the zeiss on a tripod and had a look.One of the first things that stands out, at this power and size is - how can these bins have such generous eye relief, a huge fov, and a totally relaxed and forgiving view all at the same time?...these are nearly as easy as looking through Fuji 7x50s. I was under the impression that you couldn't have all of these attributes at the same time unless your bino was a metre long? I went looking for CA (a daft thing to do) down the side of a fourteen story brick building 250-300m away I and found a touch, with eyes off axis...on axis it was superb. Then, I realised I hadn't even pulled this building fully into full focus. That focuser is like some kind of surgeons tool...I had those brick edges so sharp I could see ants crawling about on them ...in the lousiest of viewing conditions. Im getting some interesting heat haze effects as this bino ruthlessly pulls radio masts five km away into focus (it's been a long time since I used a 15x binocular of any kind). Like I said its frustratingly hazy (fires about) and the conditions are warm with bright but flat lighting. It did however have me wondering if these are a leaded glass? What are the attributes of lead glass?Cheers,Rathaus</blockquote>
