Okay, this is pretty big. Or could be, at least. ES is coming out with a new eyepiece line: 82° AFOV and long eye relief. Only three focal lengths so far, 4.5mm, 6.5mm and 8.5mm, but potential for more. A 14-15mm in this design would be pretty killer. The eye lenses are quite big. The ER doesn't seem, on paper, to be all that much better than the current ES82 line, but it does appear from photos that the eyepieces could potentially be much, much superior in terms of usable eye relief and ergonomics. See and judge by yourself:

They look great! ES is sure growing the their line, good for them! I may have to sell my ES 8.8mm and replace it with this new 8.5mm.

Am I not seeing it, or is there no mention of the actual eye relief anywhere on the page? It says "long eye relief" multiple times, but doesn't say exactly how long.

I cannot find this new line of eyepieces on the ES website. Is this coming to the US market?

It seems really odd ES would make a new line of almost identical FL with the same FOV, but just better comfort? Wouldnt that render their other pieces completelty obsolete?

I don't see these on the U.S. website --- just the old 4.7, 6.7, 8.8, etc.

Not if these cost more.  I have an ES82 5.5mm and never noticed any problem with eye relief.  Just ordered the 30mm.

They probably will cost a little more than the 82's if they do make it to the US.

 

Yes, I don't see it stating actual eye relief anywhere either, although it says they

are fit for eyeglass wearers.

They are calling it "Interpupilar distance min."

Don't know if the values are good enough for eye-glass users like me but seems not...

There's a good chance that the stated values are not true and that the actual ones might be better. I suspect that the stated values are those of the old 82° series or at least incorrect. The eye lens on the new models is much bigger than on the older ones, so it would be extremely strange, if the eye relief wasn't much better as well, instead of just one or two millimeters better.

I'd love to see a direct comparison between the 6.5 and the Morpheus of the same FL.

They do appear different. My guess is Bresser jumped the gun on these and it was supposed to be a NEAF product launch. If they have close to 18-20mm of eye relief on the 8.5 that would be awesome. I might just forget buying a Morpheus 9 and get this instead

This is getting interesting folks. Wonder which series would be on the chopping block? Big ES 82 sales this year?

I don't know but to me "Interpupilar distance min" sounds like they would work with

binoviewers, not eyeglasses. Maybe the problem is the description is coming from

a non-English speaking person. Something isn't as clear as it should be.

I'm having that issue as well. About to buy a 9mm Morpheus but now news of a new ES line makes me curious.

On the german version of the page, they use the word "augenabstand", which directly translates to "eye distance", IE eye relief, so the sentence "interpupillary distance" is just a translating error.

 

They probably just used Google translate on the whole page. grin.gif

Maybe they will just replace the shorter fl's in the 82 deg line with these for the same pricing? Heck, Televue did that with Naglers on the different types and some are crazy different designs, so maybe ES will do that and simply phase out what they have. It makes sense to replace the shorter focal lengths to give them more eye relief. Hopefully they will extend up to the 14mm, but I doubt it. The 92's and the 100's as well as the 120's only include a small number of FL's

 

It would be easier to just replace/phase out existing ones for better designs

Long eyerelief is more useful with long focal length eyepieces to allow astigmat to use their glasses when needed.

On short eyepieces, I don’t see the point of increasing eyerelief, the current offering is good enough as it is.

If the new ES 82 hits the marker after NEAF then I am going after the 8.8 82 degree when the sales hit the market. And perhaps a 24 mm, and perhaps  . . .

Interesting.

There would seem no reason to replace the entire line of 82s, since the longer focal lengths already have adequate eye relief,

so perhaps the release of just the 3 shortest focal lengths may be a tipoff of what is to come.

The eye reliefs quoted won't qualify as long eye relief, but need I remind you about all the fuss on the ES 62° and 52° which were all supposed to be long eye reliefs,

In the 62s, only the 26mm, 32mm, and 40mm qualified as long eye relief, and in the 52s, only the 30mm and 40mm.

So "Long eye relief" probably just means "longer eye relief than some eyepieces with the same focal length and apparent field",

but not, necessarily, "suitable for glasses wearers".

We'll see when they make it to the US.

Not if you are comparing the current 4.7mm ES 82 to the newer 4.5mm ES 82. cool.gif  Some still want the longer ER.

 

The 4.7mm ES 82 has very short ER.

 

However, not holding my breath on this one.....just not yet.

I can wear glasses and see the full field of the 6.5mm ES52 with no contact between my glasses and the top of the eyepiece.

It would be very difficult to beat out a 9mm Morpheus - but I have stated that the 9mm Morpheus is my all time favorite eyepiece of any FL.  I will probably give the 8.5mm a try just to see.
