I have had a few roof prisms with no phase coating. Most of them were pretty poor.They were better than having no binoculars.
My first good ones were Nikon Sporter 10x36. I still can't find any major problem with them, other than dimness. The center part, hard to say how much, is quite sharp. They don't make me disgusted with the view.
I had some phase coated 10x28 Excursions for a few days. I could indeed focus and there was a narrow depth of field in focus. I end up readjusting the diopter a lot in some models, and that was true here. I sent them back, price was $140. FOV was good, 315.
My local sports store has some non phase coated Bushnell 10x28 Explorer. Style is slightly different than what the googled picture looks like. No 8x version sold. They have a FOV of 260, and they are a bit dim. But the focusing does not drive me nuts. The clarity is not quite as good as my old Sporter, but close. Cost 45 bucks. Eye cups screw out but look a little cheaply made. I may get these for a "glove compartment" pair for the car. I keep a pair under the drivers seat.
The similar Vortex Spitfire 10x30 for over $100 I rejected also, very similar to the 10x28 Excursion.
Maybe the phase coating, even if advertised, isn't done right? Or maybe the wide field in the 10x28 excursions messes up the view?
I am in no hurry. I think I can get by with 9x25 proStaffs for now. I use a Monarch 10x42 for my routine birding bin in winter. |

It's all about quality. Kia and Volvo are both cars. |

Hey now, I drive a Sportage.
Tero,
I would agree. I purchased a set of the EO Denalis. They are phase coated but that help at all with the poor quality image that they displayed. I don't think I am going out on a limb when I say that there are some non-phasecoated roof prism glasses out there that are better optically than some phase coated models. |

You are not. Here are possible combinations: bad glass x bad coatings good glass x good coatings bad glass x good coatings good glass x bad coatings and there are many levels of good or bad, so, try before you buy and don't fall for lingo such as "XTR" "HD" "ED" C3" PXR" "ASPH" and all that. |

Right as rain!
Phase correction is just ONE item in the overall recipe of optical performance. It can't overcome poor quality in other areas. A $500 paint job on a Yugo doesn't turn it into a Bimmer. |

I have one pair of non phase coated 8x25 roof prisms, Minolta, that I like. All the others have been junk. I would have bought two or three after I heard Minolta is out of the binoculars business.Can't find the model, it was some 50 bucks or less.
I did like a Brunton Echo 10x32 and 8x32. They seemed quite good for non phase coated (which it is?), but the price in that store was too much. I can get 10x36 Monarchs for that. |

One of the places you can search for Minolta (Konica Minolta) binoculars is amazon.com
You also could try doing a google search for same. |

Yes I did that right after deciding they were good. Could not find them. They were at Scheels Sports.

I find it interesting then that some companies started charging so much more for their phase coated models with no actual other upgrades. If phase coating was so much more expensive to apply then how is it they can apply it to roof prism bins and still keep the cost under $200? I wonder what the cost of the bin would then be if there wasn't phasecoating applied. |

Anybody else have a favorite roof prism in the non-phase coated category?

Frank,
As we all know, there are companies on the planet that will try to take advantage of consumers whenever the opportunity presents itself. Isn't that why we spend hours on the Optics Talk Forum? Helping each other, & education ourselves to be able to make intelligent choices. Remember? Let the buyer beware! Caveat Emptor! Barska, for example, makes their top-of-the-line Huntmaster roof prism binocular with Phase Coating, FMC/Fully Multi-Coated optics, 100% waterproof, BAK-4, great eye relief, great exit pupil, excellent FOV & all for $120.oo. Unfortunately, their quality & reputation is not going to draw very many buyers, UNTIL their products "prove" to be worth the investment. |

I really liked those Sporter I/Buckmaster models Tero. We share that common interest. I have no experience with the early Leica/Leitz models but would love to see what a high end non-phase coated roof looked like.
Birdwatcher,
You are right ofcourse. |

The Sporter only has some buld and weight issues. I still have the 10X Sporter. When I go somewhere with my family, I give them some of my other ones, and I use the old Sporter.
I could not keep from testing the 10x28 Bushnell Explorer. Not phase coated, but I was able to see two eagles across a wide river. I saw more detail than with a pocket 8x25. Not the quality of the Sporter, but worth pretty much exactly the 40 bucks they cost. They sit at my desk at work. May put them in the car, as I have no other 10x in there.
The 8x28 Bushnell Excursion I don't need now. I have an 8x32 RedHead, one year warranty, which is supposed to phase coated. They probably are. Will have to do for my 8x32, they have almost no resale value, would get 20-30 bucks for them. |

I think he was knocking the Volvo, . . .atleast I hope he was. They generally do not show well in quality surveys. On the other hand, the Korean makers like Kia are near the top. |

Hey now. Well at least I will have a nice pair of binoculars to carry with me while I am walking for a towtruck. |
