To complement the recent comparison - see above posts #153 and #154 - of the Monarch HG 8x30 with similarly priced 8x30‘s, I did a very brief side-by-side today with the more expensive „premium“ binos Zeiss Victory FL 8x32, the Leica Ultravid 8x32 HD+ and the Swarovski EL SV 8x32, focusing only on:
- image quality at the center and
- at the edge of the field of view
- daytime straylight characteristics.
Fields of view are 145m for the Monarch HG, 141m for the EL SV, 140m for the FL and 135m for the Ultravid.
First observing outdoors.
For my eyes, the Monarch HG and the Zeiss FL give the impression of a very similar image: bright, relatively „neutral“ with good color fidelity, very good central sharpness, none to very little CA. The difference is in the peripheral sharpness, whre the Nikon is clearly better.
The Leica is different. The brownish / yellowish colors of the meadows and fields, omnipresent here after an amazing dry spell and heat period, are more intense in color; good overall contrast, the overall tone of the image is warmer. Central sharpness might be just a tad below the Monarch HG, edge sharpness, however, is much worse in the Leica, it is also worse than in the Zeiss. For my eyes, there is a bit more CA than in the Nikon or the Zeiss
What a contrast to the EL SV, with it‘s much cooler image, almost slightly tinted towards the blue or green tones, but giving a very brilliant image, and the perceived sharpness is even better than in the Monarch. And that is also particularly true at the periphery of the image; I guess no other bino beats the EL SV in this respect. The image of the Swaro is the flattest of the four, but not everybody may like the effects that go with this (globe etc.).
Indoors comparing the binos on the USAF 1951
I am aware this is not a strictly „scientific“ method to assess central sharpness, since I am still using my subjective eyes to observe, and it's only about black/white and does not give a reliable answer as to image contrast under normal viewing conditions, so it‘s just an additional piece of information how the binos perform at the center of the image.
Without booster, the differences between the 4 quality binos in question are way too small to perceive, so I used a 2.5x booster from Kite Optics and the 4x and 6x boosters from Zeiss.
Caveat: talking hereafter about results, we are really talking about nuances only, not significant differences.
On the USAF, the Zeiss and the Swaro share first rank, and the Leica and the Nikon second.
After the comparison outdoors, I had expected a slightly better result of the Monarch HG. Out in the fields, the Nikon performed so well that I had expected to see no difference in central sharpness compared to the Zeiss or the Swaro. But the results of the Nikon on the USAF were just slightly below those two, and about the same as the Leica (I had expected the Leica to be slightly behind the Zeiss FL and the Swaro EL SV).
All of the above to be taken with a grain of salt. This is the result achieved with MY eyes, others may come to different results.
Straylight performance
In 2015, I had done a review of a number of 8x30‘s with regard to straylight performance; the results are summarized in the attached table.
Testing again today, I came to the same results for the Swaro EL SV, the Leica Ultravid and the Zeiss FL.
The FL today again exhibited this pronounced veiling glare over the entire image when the objective lenses were exposed to direct sunlight at a low angle. Otherwise, it did well.
The tendency of the EL SV to exhibit all sorts reflections under special circumstances has been widely discussed (if I remember correctly, also in this forum).
The Monarch HG performed quite well today, with now significant immediate „flaw“ becoming apparent for my eyes (Altavista recently pointed out his different experience, see above post # 152).
fwiw
