As the SLC 10x56 HD is incredibly bright already, the SLC 8x56 HD - that shares the same Abbe-Knig prisms - should be even better in this respect. And the SLC 10x56 HD is visibly brighter than the Ultravid 10x50 HD+. Therefore I would bet that the Noctivid 8x42 is clearly less bright than the SLC 8x56 HD. But in fact I have not compared them side by side so it remains just my assumption.

Hello,

the Noctivid is something as bright as the Zeiss SF 8x42 or the Swarovski 8,5x42, under these three binoculars I could not notice noticeable brightness differences!
The Noctivid I do not have anymore, but the Zeiss and the Swarovski and here is the difference to the SLC 8x56 more than clear.
The SLC is in terms of brightness, a real powerhouse, so much brighter than the Noctivid!
It is important, however, that one can really use the exit pupil, which uses the glass when the pupil "only" about 5mm. opens?

Thanks! Im trying to decide between the 8x42 Noctivids and the SLC 8x56. I really like the idea of brighter SLC for early morning and late evening.

Hello,

Interesting!

Where would you see exactly the advantages of the SLC over the Conquest, sharpness, brightness, chromatic aberration, edge sharpness and so on?

Thank you,
Andreas

Most would not compare those models since they are different platforms, 42mm and 56mm AND different brands. Also there is a size/weight difference as you well know.

I have the Noctivid 8X42 and a SLC 10X56. The Noctivid weighs 30.5oz and the SLC 42.6oz.

There won't be much that you could ask of an 8X42 binocular that the Noctivid WON'T do. It is a very bright binocular as is typical of most at that price point. The SLC will be ever so slightly brighter due to a larger objective and the use of AK prisms. Will you notice that and will it be useful to you is the question. IMO it is certainly not 12 ounces better. I'd pick the Noctivid for 99.9999999% of my uses.

When I ordered the four Nachtglser at the reputable German dealer optik-pro.de, their advisor recommended to ignore the Zeiss 10x54 HT and the Leica 8x50 and to concentrate on the two 10x56 from Swarovski and Zeiss. I was sceptic but have to admit that he was right.
To your very question:
The Conquest is less expensive and it feels cheaper. The coating and the armor are IMHO not superior to Asian medium-class products. The diopter adjustment on the right ocular is rather primitive and moves the outer lens. The eye cups however are comfortable and suit my face very well, even better than the SLC's.
The field of view is also larger but at a price: I am sensitive to cromatic aberration and the Conquest shows visible green/purple halos on contrasty edges in daylight. CA artefacts in the SLC are minimal. Moreover the edge sharpness of the Conquest is ok but not really good. The colours are fine, slightly warmer than the SLC's. Brightness is excellent but the SLC is still a tad brighter. All in all the Conquest is a very good bino but the SLC is in my opinion a bit better optically and distinctly more convincing in terms of construction and build. The SLC feels like an alpha to me and the Conquest not. And because I wanted simply the best the choice was easy. Nevertheless the Conquest is a very fine bino that should satisfy most even demanding customers. If the SLC 10x56 wouldn't exist, I'm sure that I would be happy with the Conquest 10x56, especially since I mainly use it in low-light surroundings. On walks in bright light I prefer my more compact Leica Trinovid 8x42 BA that I bought back in 1993.

Thanks a lot!

I know the Conquest series, myself have the 10x32 and had the 8x32 so I know that you have mechanically lost something, I was mainly interested in the visual differences and how large they judge.

Hello Chuck,

Do not forget the almost 2mm. larger exit pupil, which is already important here, always provided you can use it.

Thank you for this response. You have helped me make up my mind! Im going with the Noctivid 8x42.

8x42 Noctivids arrived today. Found a great deal on brand new in the box pair from the Netherlands for less than $1900. Tried them out a little this morning. The best part is how they work with my eyeglasses. On the second setting of the adjustable eye cups they are perfect as far as the FOV. Much much better than my 10x50 BAs Ive had for 25 years. They are brilliant and magic as far as sharpness. I cant wait to try them out in low light tonight and compare them to the BAs for light transmission. They are heavy but much smaller than the BAs which I take on a hike almost every evening. That will be nice not having to lug the 10x50s around. Carried those on my shoulder instead of around my neck.

Congratulations on the Noctivids. I also found them to be a great fit with eyeglasses. Compared to the 10x50 BA's you'll be getting more than half a pound reduction in weight, as well a full degree wider field of view.
Please report your observations about brightness at dusk and early morning between these 2 bins. If your pupil is adjusted for low light, I expect the 10x50's will prevail, but am curious as to how and when you'll perceive the difference.

Also, you might try a Rick Young Harness for the Noctivids. It distributes the weight very well on both shoulders.

Enjoy.

-Bill

Thank you Bill. I was not able to stay out as late as I wanted to tonight but just after the sun went down I was able to compare the Noctivids to the 10x50 BAs. There was clearly a difference with the Noctivids being brighter than the BAs. Ill try again tomorrow to compare a little later in the evening. I was surprised that the BAs werent brighter but that is probably a result in the difference between 8 x and 10 x powers. I will definitely look into the Rick Young Harness. Thanks for the tip!!!

The 8x42 Noctivids are slightly brighter in late evening hours than the 10x50 Leica BAs. Not a huge difference but I was surprised it is noticeable. The best thing about the Noctivid is the full frame of view when looking through my eyeglasses. I dont quite get that advantage with the Leica BA even with the lens cups all the way down. Interesting how they accomplished that. I have the Noctivids eyecups screwed up to the first setting. Really like the much more compact size!
