Hello,  I was considering purchasing an IOR 2.5-10X42 hunting scope but have learned, although not easily, that the hunting line use the T3 lens coating system and the Tactical version uses the MC-7 wide band coating system.

 

First question, what is the difference between the two and which is better???

 

Secondly, how do these two scopes compare to Leupold, Zeiss, Khales, or any of the upper end scopes.  I have read many things and I am interested in the best quality scope I can get optically and mechanically for the buck.  

 

It will be going on a Sako 75 Finnlight. 

 

Thanks for any help

Eric

I would lean towards the T-3 glass... That should be the new arsenic free glass that is used by Contax, Hassleblad, and Rollei for camera lens.

Koshkin:

The IOR's are using the T3 coatings???

I thought they were just the "T" coatings.

 

Welcome to The OT.

 

I don't mean to high jack your thread, but I wanted to ask our resident IOR guru a question.

Leupold, Zeiss and Kahles all make a better "hunting" scope than IOR, IMHO.

Cheaptrick thank you much for the info and not wanting to offend but I really would like to know technical specifics as why Leupold is better instead of opinion.  I would assume the euro versions of Zeiss and Kahles would be better but what about there american versions.

 

I really want to know more about the MC-7 coating as well as the T3 coating

 

Thanks much again all!

 

Eric

This may be a step out for me, but here goes. Koshkin, correct me if I'm wrong. They put coatings on the different glass due to the composition of the glass. Therefore, Different glass composition would require different coatings. also the glasses location would determine the coating. Zeiss, Kahles, Leupolds or any scope manufacturer, all try to get the maxium light transmission and chromatic transmission without distortion or color loss. Thus the different coatings.

I apologize, I got the 2 coatings turned around.

 

The T3 are indeed an IOR coating, and the T* is the Zeiss coating I was thinking of.

 

I zigged, when I should have zagged....

 

I'm just not what you might call a "BIG IOR fan". I had some issues with 2.5-10 Tactical model. Long story.

And yes, I have owned a hunting model IOR that didn't impress me much either.

 

I think that the better Leupold, Kahles, and Zeiss models will make a better hunting scope.

I'll take the Zeiss Conquest over the IOR any day.

 

I'm sure when koshkin shows up here, he'll tell you that he prefers the IOR. At least over the Loopie.

 

Here's my bitch list for IOR:

Short eye relief

I don't care for the "yellow" tint of the coatings/glass

Warranty/CS dept WAS suspect at times. Maybe better now.

Objective lens housing can be backed off if not careful.

(Ask me how I know.)   

 

You may buy a IOR and think it's great.

I guess one thing that would help me clarify what I am looking for is the difference between the T3 coating the T* coating and the MC-7 coating and which of the two on the IOR's is better the T3 or the MC-7 and why??

 

Thanks

 

Eric

Ok, i guess I have another question.  Which scope would be best overall for hunting conditions...The IOR 2.5-10X42 or the Conquest 3-10X42 ?

 

 

Thanks again

 

Eric

LOL ok let me try that again.  I am looking at the IOR 2.5-10X42 Illuminated compared to the 3.5-10X50 Conquest (non-illuminated)

 

Thanks um...........again!

To the best of my knowledgel, current production Hunting and Tactical scopes (possibly except for the 4x32 which is an older design) have the same, presumably MC-7, coatings.   IOR used T3 coatings until 2001 or so.  In 2001 they changed the optical design a bit, which included some glass type changes and updated coatings (MC-7). 

Coatings are matched to a particular glass and to a particular wavelgnth.  Although these are referred to as broadband coatings, they have maximum transmission at a particular wavelength (or color if that is a more convenient designation). 

As for the yellow tint that cheaptrick mentions, that is pretty much a thing of the past.  Current production IORs do not have it any more.  Pre-2001 optics have a yellowish tint which actually helps resolution, but sacrifices some color fidelity.

Nortac, if you do not mind me asking, where did you find out that hunting scopes still use T3 coatings? That's contrary to what I understood.

As for Conquest vs IOR, if you want a 1" scope (likely lighter) go with a Conquest.  If you want a ranging/holdover eticle, go with the IOR (MP8 reticle).  Both are good scopes.

I stand corrected. My IOR's were older models, I admit.

 

Yeah, that MP8 is a good ranging reticle. Not real busy either.

 

I'd forget about the illuminated reticle, unless you want to go all the way and get a S&B.

Anything else just ain't worth it too me.

(One of my 2 IOR's had a lit reticle.)

Thanks much for the information.  Koshkin, this is the link where I read about the T3 coatings.   Orginally, I called them and planed on ordering one of the scopes but I felt I was being misled.  I was told the Hunting scopes used T3 coating and the Tactical used the MC-7 coating and I was told the MC-7 was better.  Based on what you have said it looks like the hunting scope that was being pushed may have in fact been a pre 2001 version, although I cannot be sure of that but I was told there was a difference between the coatings on the hunting vs the tactical.

 

forgot the link -  http://www.usaoptics.net/iva2prhusc30.html

 

Anyway, I am still trying to figure out what to do. Now I am looking at the Kahles 3-9x42 cl multizero.  Not sure if I care for the AO and wodering just how it compares to others.

 

 

 

 

Thanks for the input all!

 

Eric

No AO's for a big game rifle. Few exceptions to this rule.

 

The Kahles is a nice scope though.

If you look at their website, they also mark a lot of tactical models as having T3 coatings.  To be more exact, I think that they mark every scope that was in production since before 2001 as having T3 coatings.

To the best of my knowledge, they are wrong.  You can try to call IOR to really confirm.

As a general rule, there are lot of retailers out there who either do not know what they are talking about or will say anything to sell their product (or both).  I would suggest you talk to better retailers like SWFA.  If they do not know, they'll tell you as much and/or try to find out.

Unfortunately, there isn't a ton of info on the Kahles CL.  Go to the top of this page & use the "SEARCH" function.  That will help you out a ton.

 

I know that IOR makes a great product but, as an owner of a CL, this new series from Kahles is fantastic.  I can't imagine any reason why you wouldn't like the glass & features of a CL...
