Are we talking about the older Prostaff 7, or the new Prostaff 5, which apparently lacks phase coatings?
Considering that the Nikon Prostaff 5 Field / Spotting Scopes have phase coated prisms it would be odd if the binos didn't ... however the new Prostaff 5 10x42 binos are cheaper than the old Prostaff 7 10x42 ...
Go figure ??
peatmoss,
I think the Pro-Staff 5 does have phase coatings. On the new Nikon website they often are not mentioned when they discuss the coatings on the lenses and prisms. You will find a comment about multi coatings on the prisms along with the comments of multi coatings on the lenses. See the comments on the coatings on the lenses of the Pro-Staff 5 below:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7571/PROSTAFF-5-10x42.html
Even the comments on the coatings on the EDGs do not mention phase coatings on their prisms. On the old Pro Staff 7 phase coatings are mentioned.
On the Monarch 5 they don't mention phase coating either, in fact, they show a picture of their prisms without mentioning it! See below: Scroll down to look at the prisms.
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7581/MONARCH-5-8x56.html
On the Monarch 7 ATB phase coatings are mentioned but on the new Monarch 7 8 x 30 they aren't mentioned.

Go figure.

I can buy a Pentax 8x36 NV for $150, and it's competitive optically with the P7 except with smaller objectives.

. ......... I can only imagine that Nikon is counting on the ignorance of people about the necessity of phase coatings on S-P prisms, which is a shame.
Where Nikon should offer 10x50s and 12x50s is in the EDG series, so they can compete with Swarovski, but instead it looks like Nikon wants to win the race to the bottom. Count me out.

In case anyone finds this thread looking for information about the new Prostaff 5, I just heard back directly from Nikon that they do have phase-correcting prism coatings.
Brock, did you mean the P7? To be honest I didn't pay the NV a lot of attention but my impression was the P7 was sharper, had better, contrast, colour rendition and CA control and also sells for $150 your side of the pond. If you are OK with the size and weight it looks like a better buy to me.

You may be on to something here!:smoke: Or you may not be on to something which is why I am responding in depth.
It is because Nikon does not mention having Phase Coatings on the Nikon EDG series prisms either! Their website doesn't have them listed as a "Key Feature" in their prisms, just like with the new Prostaff 5 which is the subject of your complaint.
That doesn't make sense does it?
See Nikon's statement about the multi coatings on the lenses and prisms of the Prostaff 5. Phase coatings are not mentioned.
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7571/PROSTAFF-5-10x42.html
There is NO mention of phase coatings on the prisms of the 10 x 42 EDG:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7567/EDG-10x42.html
I was about to conclude that Phase Coatings were no longer important then I found out that somehow Nikon decided to put them on the Monarch 7 ATB prisms.
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7548/MONARCH-7-8x42-ATB.html
Phase coatings are mentioned way down at the bottom of the binocular features on the new Monarch 7 8 x 30s like an afterthought:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7579/MONARCH-7-8x30.html
And I notice that they are mentioned as a "Key Feature" on the old Nikon 10x42 Premiers:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7536/Premier-10X42.html
But they aren't mentioned on the Monarch 3 Realtree binoculars even though the prisms are pictured therein:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7574/MONARCH-3-8x42-Realtree-APG.html
Nor are they mentioned as being on the Monarch 5 See photo of prisms therein:
http://www.nikonsportoptics.com/en/Nikon-Products/Binoculars/7577/MONARCH-5-10x42.html
There seems to be a problem of consistency on the Nikon website, as usual.
IMO unless we hear from Nikon otherwise I think we can be confident that all of the above binoculars have phase coated roof prisms.
It's time for Mike from Nikon to make a comment here before this accusation of "lack of phase coatings" on modern Nikon roof prism binoculars becomes an "internet legend!":eek!:

David,
My point was about the new P5, which doesn't appear to be phase coated. What I was saying is that I could by a Pentax 8x36 NV, which is phase coated, for $150, so why would I want to buy a Nikon 8x42 P5, which isn't, for the same price?
