Nikon EDG 2 CA? (1 Viewer)

NDhunter said:

I have experience with the EDG models in 2 sizes, the 10x42 handles CA well in the center,
but you can force it near the edges when testing on high contrast subjects. This is similar
to other top HD binoculars. The Swarovision is similar, I have directly compared them.
You will not find any issues in normal use.

I also have the 10x42 SE, and it is very nice, but the EDG is better in many ways, better edges,
and brighter. The EDG model also has a wider 6.5 deg. FOV, and every bit of it is enjoyable.
The SE's FOV is 6 deg.

The Allbinos review of the 10x42 binoculars is a good resource on both of these mentioned along
with many others.

Can anyone comment on the amount of CA in these binoculars>? Is it so little that you won't notice when spotting a bird against a blue sky. I want to get a pair of refurbished. My previous Premier SE 10x42 were spectacular but the CA made them unusable for me.,Thanx

Tumbling, Tumbleweed,

You must be extra susceptible to CA, because I found the 10x42 SE to have low CA, and I'm susceptible, too. The Nikon 10x42 LX/HG had too much, the LXL even more. But like the 10x42 SE, the image was otherwise spectacular.

I tried Jerry's EDG I, which AFAIK, has the same optics as the EDG II. Nikon redesigned the body to keep from getting sued by Swaro, and there was also a defect in the focuser, causing the knob to come loose.

I compared the 10x42 EDG I to a 10x42 SE (not the latest version, which I later bought from Jerry). The overall view between the two bins, SE and EDG, was similar except for the 3-D effect, but the color saturation and contrast was better in the EDG due to the newer coatings and ED glass. And as Jerry mentioned, the EDG's FOV is noticeably wider.

To my eyes, the EDG I controlled CA even better than the SE in high contrast situations (birds perched on a power line against a gray sky background), however, there was still some CA on-axis. The best CA control in that EDG sample appeared not far off axis (toward the top) rather than on-axis.

The 10x42 SLC-HD did a better job of controlling CA than either the SE or EDG. I looked at birds on power lines, tree branches, etc. and I couldn't induce any CA on-axis or off axis until I got toward the edge. The only 10x bin that performed as well in this regard was the Celestron/Eagle Optics 10x42 Voyager ED I owned, and that was a porro, with no internal focusing lenses to add CA.

If you are really susceptible to CA, you might want to try the 10x42 SLC-HD. Ideally, compare it side by side with the EDG and see which one works better for you. The SLC has a "warm" (red) bias, so if you like the Nikon view, you probably will like the SLC-HD, too. Not quite as wide FOV (6.3*), but more "open" than the SE.

Regarding buying Nikons refurbished. Refurbs only come with a 90-day warranty. After that, repairs are out of your pocket.

Decided to order the EDG II's after all. If they work out the price can't be beaten. With a refurbished bino you have 1 tech doing them from start to finish, should be just fine.
