Exactly and how inset the front objective lens is. The more the better. There can be other causes as Henry explains here why the Habicht 8x30 W has veiling glare in the link.I find the reasons why some binoculars control veiling glare and flare better than others baffling.:h?::smoke:

Why No More High End Porros?
Coz all the cool kids have roofs.
Me mid 70's Habicht 10X40 is a champ at controlling CA. It's only when you ease close to the sun that glare becomes an issue. Looking Sw this morning at a Red tailed hawk perched in a back yard tree under overcast winter sky the auld Swaro showed no CA.
It is interesting that the 7x42 Habicht is good at controlling glare and the 8x30 W is not. I tried the 7x42 Habicht once and it didn't work well for me eye relief wise. The two Nikon porro's. The SE and EII are very good with glare so why couldn't Swarovski correct the problem on the 8x30 W Habicht. It has been said by another member the Canon 10x42 IS-L is your alpha porro. It is one of the only porro's with ED glass and optically I find it one of the best binoculars made and then it has IS on top of that.AND the manufacturers have been exrtolling the virtues of roofs since the 1960s.
Only at the time roofs weren't anywhere close to well-made porros. Now they are closer, and yet I feel a well-made porro would be better than ANY roof, at least optically.
I've got two Habicht porros, a 7x42 and a 10x40. No CA, and the 7x42 is one of the best binoculars I know when it comes to controlling reflections and veiling glare. The only roof that is on the same level is the Noctivid. The Habicht 10x40 is also very good, better than most roofs.
A shame Swarovski never made the changes to the Habicht 8x30 to get rid of its glare problems. Would have made an excellent binocular for long hikes and so on.

That "baffles" me why you would nominate that? It went right over my head the first time.I nominate this for 2017 Pun of the Year Award. :t:

You have a SUBURB called "Goatstown"? That is funny. We have a town in the state of Arkansas called "Wiener". Now top that one.3Dennis...this is a pub called the Goat Grill, in a suburb called Goatstown, not far from where I live.8-P
"I'm beginning to think that overall optical quality might be readily judged by the ability to handle CA."It seemed to me that the lighter roofs did not handle CA well. Perhaps I haven't sampled enough bins. Howevah, the 10X40 Habicht, lacking armour, even as a porro is extremely light.
I'm beginning to think that overall optical quality might be readily judged by the ability to handle CA.
"I'm beginning to think that overall optical quality might be readily judged by the ability to handle CA."
I think you are on to something here. In telescopes CA is everything. I think binoculars are very similar in that respect.

You can't remove one aberration without making others worse. UNLESS you want to add elements which will add cost that some folks would refuse to pay and weight. And as you know some people would like an 8x40 that weighs as much as 6 postage stamps. Then there is the lessening of throughput and scatter because of those extra elements. Our logic (with nothing at stake) does not match the manufacturer's logic (with EVERYTHING at stake). :cat:
If someone on this forum will show the manufactures how they can make such improvements without losing their corporate shirts, I'm confident they would follow suit.
