A few days with the Pentax ZD 8x43 ED
I am very pleased to see I am not alone to really appreciate long eye relief! Because it's obvious that wide FOV by the most people, and by manufacturers is considered as more important than ER. Especially I wonder about the common difference between 8x25 and 8x30/32. There are several examples... -

A few days with the Pentax ZD 8x43 ED
Thanks! According to that specification 8x43 has 50,3deg AFOV and 10x50 has 49,7deg. It should be exactly the same because it should be the very same ocular design, so it's probably just a rounding deviation due to unprecise FOV of 87 vs 110m. Or that the magnifications are not exactly 8 vs 10x... -

A few days with the Pentax ZD 8x43 ED
By the way: at Cloudy Nights forum I read that the 10x50 of ZD ED only has 47deg AFOV. If that is correct, it should mean 8x43 has it as well, because they share the same eyepiece model, right? Then the TFOV is only ~5,9deg. Edit: I found information. Allbino measured TFOV as almost exactly... -

Ok...maybe PRETTY identical is a better word. 😉 The outer design is almost identical, as well as the FOV is. But I expect better sharpness, contrast and brightness. Maybe edge sharpness as well, I don't remember how well DCF SP performed in this respect. -

A few days with the Pentax ZD 8x43 ED
By the way: I forgot to tell that I already have experience of this binocular. More specific I had a 8x43 DCF SP 15 years ago or more. But I bought a Swarovski SLC 7x42 neu, and sold the Pentax. DCF 8x43 SP was good but SLC 7x42 a step up in image quality and with a larger FOV. ZD ED seems to be... -

A few days with the Pentax ZD 8x43 ED
I understand Pentax ZD models have not been taken seriously by birders and binocular nerdys because of the only 50deg AFOV. But I think it's good they don't sacrifice eye relief in order to get wider FOV. One example of that is Vortex Viper HD 8x42 and 10x50. The former series had around 50deg...
