10X50 Swarovision (1 Viewer)

Here's a quick reminder of the increase in ligh gathering for standard binoculars, the numbers can be added up.

From 20 to 25mm : +56%
From 25 to 32mm : +64%
From 32 to 42mm : +72%
From 42 to 50mm : +42%
From 50 to 56mm : +25%

As a quick note, it is interesting to note that even though the difference between a 50 and a 56mm is "only" 25%, if one takes into consideration that top 56mm use abbe koenig prisms which add another 3 or 4%, we get near 30%, this is the sort of advantage that a Swaro 10x56 HD will have over a 10x50 Swarovision...


Speaking of brightness and binoculars ...

I think that Docter 10x50 Nobilem is a little underrated.
I had the opportunity recently to compare it with Zeiss Conquest 10x56 HD - Abbe Koenig prisms. Also available was the new Leica HD plus 10x50.
Docter not so sharp at the edges of the image as opposed to other competitors - although it has a slightly larger field of view - while the other parameters did not leave them a chance.
Brightness, sharpness in the center, the 3D effect. - Sharpness in the center of the Leica was comparable to Docter.
Outside the building in bright light, the difference in brightness between the binoculars was small.
In a dark room under artificial light, Docter showed what he can do. He was clearly brighter than the Leica and Zeiss.
Comparing all three of binoculars on a busy street in Warsaw, the image of the Leica and Zeiss seemed quite flat in comparison with Docter, although in this fight Leica fared worst.
Taking on the street to hand Docter I thought - this is it!
Docter is also well balanced and shape of binoculars allows comfortable and stable hold in their hands.
It is of course a lot cheaper than the other players, but even if it was expensive, it was worth that money.
At the end of a small note on the guarantee.
Leica 10 years
Zeiss 10 years
Docter 30 years
 
There have been some questions on this thread about direct comparisons between the EL 10X50 and the 10x42.

It's not really fair though to compare a 50mm aperture binocular to a 42mm one. All else equal, a 50mm will always be brighter and have a bigger exit pupil (for more comfortable viewing) than a 42mm.

Just wait until Zeiss launches the 10x50 Victory SF: it will blow the Swarovski 10x50 SV EL away like autumn leaves in a hurricane! ;)

sorry to say, but zeiss already have the 10x54 HT,

I don't think there will be at 8x32 SF either actually.

right now zeiss bino line up feels a bit
messy actually,
old and new models, cheap and alpha,
FL:s, terras, conquests, SF, HT
naahh…I'll take the green pill…instead of the blue I think...
:-O

And I think that is quite wise by zeiss,

Well, I was half joking, but I disagree with you that Zeiss is not likely to offer an 8x32 SF. It's the logical next step if they want to compete with Swarovski (namely the 8x32 EL SV).

Zeiss doesn't need an 8x32 copy of the SF to compete with the 8x32 EL SV. All they need is one with a flat field. That should be easy to do. It will probably be lighter and smaller than the Swarovski.

Swarovski didn't change the body of the EL to any great extent when they made the SV.

see my updated previous post,

don't think the market is big enough,
now when then conquest HD:s exists,
most birders tend to prefer 42mm
but a 7x35 SF would be fun,
but i'm probably wrong as usual,
:cat:

but a well balanced and light 10x50 SF
would be a dream..

but now back to the swaros…
:)
 
FL's are on their way out, and SF's are their logical replacements (why make a 8x32 FL, but no 8x32 SF?). Anyway, as you said: back to the Swaros! ;)
 
Nobody. But it would be weird for Zeiss to be the only alpha maker without a top-shelf 8x32 in their lineup.

Who said it isn't going to be a top shelf 8x32?

It might be a flat field binocular with a completely redesigned exterior. Who knows? Remember, the old FLs all looked the similar but the 42mms and up had AK prisms and the 32mm used SP prisms.

They could come out looking like the HTs.

Yes, it's all speculation at this point, but there is some anecdotal evidence to suggest that Zeiss will indeed introduce an 8x32 SF. Namely, another poster (was it Lee maybe?) reported that Zeiss representatives at some exhibition or other gave a good grin when asked if there would be an 8x32 SF in the future... ;)

Thanks for the kind response. You are right in the fact that I did the math backwards.
Who cares...the sticky focus wheel slows down the photons so it all comes out in the wash.

BTW...I started this thread so let's get back on topic. Swarovision 10X50, the alpha's alpha.

Well, there you go! What more proof do we need?

Did our "man inside" see anything in that grin to suggest when we might see the launch of the world's longest (and probably most expensive) 32mm binoculars?

Hi.

There have been some questions on this thread about direct comparisons between the EL 10X50 and the 10x42. Last week I spent 90 minutes at Lakeside Opics just south of Bristol UK mainly comparing the Zeiss Victory SF 10X42 against the EL 10X50 and 10X42. I had anticipated buying the Victory SF.

2 days later I spent another hour at Lakeside Optics mainly comparing the EL 10X50 against the SF 10X42 but also trying the EL 10X42. I left having purchased the EL10X50. Let me stress that I am not a technical expert on binoculars but I have huge experience of using over 15 pairs over the last 50 years. Also I am lucky enough to have very steady hands so the 10X is not a problem. Finally my requirement was for a general purpose binocular; general views, horse racing, birding (about 50% of the use). No astronomy.

The main difference between the EL 10X50 and the 10X42 is the brightness. At LO I was able to compare the binos looking across Chew Valley Lake at distant scenery and into a nearby wood looking down paths and under low hanging branches. In all cases the 10X50 was noticeably brighter. This was during the daytime in late morning on both occasions. They were both dull and cloudy days. I also looked at gulls and other birds. One major difference between the EL10X50 and the other 2 sets, which I had not expected, was that looking up into the sky at the undersides of birds, how much brighter they are through the EL10X50 and how much clearer the colours are. The 10X50 had a wow factor that I did not think that the 10X42 had. Incidentally the Zeiss SF is notably brighter than the EL 10X42 but less so than the EL 10X50. It did not blow my breath away, which was caused not only by the brightness but also the sheer richness and 3Dness of the view through the EL 19X50. I am probably expressing myself badly here.

Last night I spent quite sometime with a friend's EL 10X42 as the night descended comparing them against my 10X50. TBH initially the difference was not as great as I had remembered at LO but, as the evening descended, the 10X50's just pulled further and further ahead.

Much has been made of the extra weight of the 10X50 versus 10X42, 998 gms versus 840, an increase of 158 gms (5.5 oz) or just under 19%. TBH, they are not the bino for less strong people or those with weaker wrists. I do not find this a problem. However I do use a Swarovski harness and this makes a HUGE difference. The weight is taken off the back of the neck and spread equally onto the shoulders. As you raise the binos to the eye, they are pulled (comfortably) into ones eye sockets. My advice is to spend time trying various adjustments. I find that I wear the harness considerably tighter than I first expected to gain the maximum benefits.

These are my views for what they are worth. I am delighted with the EL10X50 but I am in the honeymoon period after purchase. Lakeside Optics gives a 16 day return period but I just cannot see myself returning them. They are not much more expensive than the 10x42 in percentage terms but IMHO offer so much more.

The attached photograph shows, from left to right, EL 10X50, SF 10X42, EL 10X42 and EL 10X32,

My strong advice is to spend a lot of time comparing any binocular that you are thinking of buying against its competitors. Only buy if you are certain!!

Thanks for your review on what you see with these fine binoculars.

What strikes me is the photo showing the size comparison, of the Swaros.
and the Zeiss SF. I have not had a chance to see the new Zeiss, and it looks very long, similar to the 10x50, and much longer than the 42mm EL.

I agree, it is good to try all of these, and find out what works best for you.

I Know we had lot of Praises for this model and I also wanted to buy this 10*50 only. I don't think I will be able to manage its weight. Regarding brightness, I think during the day time it should not be different than 42. Yes there have been lot of praises for its WOW factor. I wish it would have been lighter by 100-150 gms. I would have taken the plunge.

If you take the plunge in the Ganges, and use the 10x50s to watch shore birds, the buoyancy of the water will make them fell lighter. ;)

The EL 50mm and the SF 42mm is the same length (174 mm vs 173 mm),
the EL 42 is about a 1/2 inch shorter (160 mm)
so the difference in length are not huge,

pretty impressive compactness in the EL 50mm,
 
Well, there you go! What more proof do we need?

It might even be the worlds widest PORRO..
;)

definitely missing a porro in the zeiss line up,
:t:

I would say that is not really correct. All else equal, at daytime if eye pupils constrict to 2,5mm both 10x42 and 10x50 will act like a 10x25, and consequently be equal bright.
Still the larger exit pupil of 10x50 will contribute to a better comfort because the eye positioning is less critical.
