William Optics 7x50 ED binocular minireview

William Optics 7x50 ED binocular minireview

I’ve have a William Optics 7x50 ED for testing and I’ve had it out just a little so far. So I can report some early findings.
............
This is a very nice binocular. Some users are content with low power views. It would not be my binocular of choice for astronomy, but it could be for any number of people who cherish those low powers wide swaths of sky. This particular binocular could provide you those views. It seems pretty comfortable to hand hold and produces no false color or internal reflections to speak of. If you have the large eye pupils to take advantage of this 7.2mm exit pupil, you would have a very bright image. This large exit pupil will also make it easy for you to hold onto the view in daylight, although your effective aperture would be much smaller. Still, the image seems crisp and daylight color rendition seems pretty natural.

I was impressed that the WO ED did not show any edge CA when looking at tree branches against sky background. So I wanted to check on the same branches while still under bright skylight how several others performed.
Oberwerk 8x56 shows purple band one side, green on the other.
Captain's Storm King Mark II 7x50 (older version Swift origin) shows a thin yellow/green band at edge.
Fujinon FMT-SX 10x70 shows yellow green band at edge.
If this binocular were made available in 10x50, and met the same criteria I see in this sample, I would think it would vie for position as one of the best 10x50s on the market.
Looks like William Optics is reading the Forums. Same price too! $299.

I hope WILLIAM IS reading. I'd like mine a 25X80 ED with 3 deg FOV and I AM willing to pay the price. The 80mm and larger premium bino segment is completely ignored by Fuji, Nikon, and Takahashi. Maybe we should encourage the Koreans to enter the market. They are doing so well in autos and electronics. I consider some of their LCD TVs superior to the Japanese.
Very few can afford the $4,500+ Kowa 82 mm FL but I think a top quality 80mm ED for $1,499 is very reasonable. Many don't seem to have a problem paying that much for a 10X42....

The WO 10x50 seems very identical to the Oberwerk and General 10x50. The stated ER is just 16mm, and the image at WO website shows that the ocular lenses are deeply recessed. That isn't good.

For me the problem is that 10x is just a bit too much magnification to hand hold without image stabilization .. as is the 3.5 lb mass.
But if I'm going to set up my P-mount, I'd rather go larger in aperture and high in power (e.g., my 15x70).

well Phil there's always the 7x50 if 10x is too much for you. And 15x70's from the same series are available as the new Oberwerk Ultra.
For me the main reason for not getting the 10x50 would be the IF. I can consider it for larger binoculars (say the 22x85) which are really astronomy-only, but for something that's likely to be used during the daytime as well, I'm not ready to consider IF yet.

Mark ,
I'm intrigued by your inclusion of the word YET !
Are you expecting something to happen to you in the future which may suddenly make you change your mind about this ?

dementia? 
More seriously Kenny, as you know well, it could be my perspectives change when for example I'd need to wear glasses.

I hope this doesn't mean they are changing their minds about the price: $299. is very reasonable.

The Price is still $299. For some WO products you have to click the "add to cart" symbol to see the price.
http://www.william-optics.com/wo_shop/catalog/product_info.php?cPath=27&products_id=86
I noted the 8X25 Seimi APO pocket bino price has jumped from $69 to $99. This bino looks identical to the Burgess Vireo I purchased last year for much less. (Burgess listed theirs as water resistent not waterproof, no mention of 1/2 APO wither)

I agree. I would consider IF on a pair high power MOUNTED bino for astronomy or LONG range terrestrial observation, not for a pair of hand held bino. If I am going to mount a pair of bino I would want at least 15X.
Not sure what I would use a pair of 10X50ED Waterproof, IF binos for. My skies are not dark enough to take advantage lower power 10X50 for astronomy and I don't think I need bigger objectives than 10X42 for daytime viewing. Have not found CA to be a factor in 10X50 binos yet....

I agree the ED feature is probably overkill, but a 10x50 binoular in in my area is worthwhile for hand held astronomical observing. I'd like a good quality 10x50 model for this purpose but I haven't been able to force myself save for a Fujinon, up to now. The William Optics version might be nearly as good and at a particularly decent price, as well.

For me the main interest in these "series 8" models from United Optics, is finding out to what degree the claims made on the website hold true: "exotic eye-piece design", "equally sharp from center to edge", etc.

When I tested the WO 7x50 ED, I found uneveness to the sharpness of field, it was off-center. But far outweighing that was the fact that this WO 7x50 binocular was able to resolve a 39" double at 90% out or 70% out (reflecting that uneveness). That fact that a 7x could resolve a 39 arcsecond double that far out from center results in an apparent separation of 273 arcseconds and puts the sharpness of field of this binocular on a level with the Nikon 12x50 SE (264" apparent at 80%). It surpasses the Fujinon 16x70, which has 300 arcseconds at 70% out and 350 arcseconds at 80% out. Few other binoculars even come close. 350 arcseconds of apparent separation at 80% out from center is excellent. I can count on one hand the number of binoculars in which I have seen that. I hope the 10x50 produces the same results.
