Hi to everybody. Today I received from Swarovski Optik Italy an exemplar of 10x50 Swarovision to write a review for my website. In the next days i've the opportunity to compare it with my copy of Swarovision 8.5x42. I must say that Swarovski has done an excellent job: light weight, flat field, excellent field (6.6) and FOV. The focus knob is more fluid than my 8.5! The contrast is excellent, as well as the color rendering and the containment of chromatic aberration.

I liked the weight. Today I used it for two hours to the lake. I've observed cormorants and gulls. It's well balanced and weighs like my old Kowa Genesis 8.5x44. The panning is great! I still have to control, carefully, if Swarovski has reintroduced a bit 'of pincushion distortion, but the ball rolling effect seems less than what I see in 8.5x 42 version.
Tonight I shall use it for astronomical observations
I'll take two weeks before writing a review. If you want you can follow the updates on my blog blog.binomania.it and on my website www.binomania.it
Best Regards from Italy

Looking forward to reading your observations, will you be giving the 12x a test drive also?...

Ciao! Piergiovanni,

Glad to hear the focuser knob is smoother, didn't care much for the focuser on the old (slow focus) EL I tried, which turned harder in one direction than the other. Definitely not what I expected at that price point.

Two weeks? What are you going to do a stretched out early Messier Marathon?

When the 8.5x and 10x42 SV ELs first came out, some 10x owners also reported seeing less "rolling ball" in their 10x after comparing them to the 8.5x. Could be the larger the FOV, the more obvious the "rolling ball". Holger and Henry both mentioned this about bins with narrower FOV showing less "rolling ball" even when they have a low amount of pincushion (though 6.6* is by no means narrow for a 10x50).

Since you see "rolling ball" in the 8.5x model, I'm wondering if the "rolling ball" eventually disappeared (some people adopt to it over time), or did you just not find it annoying?

Looking forward to your review of the 10x50 SV EL.

Btw, I enjoy reading binomania (the best I can, with Google's broken English translation). I particularly liked the review of the 8x42 SLC-HD and all the nice photos you took of it.

Ciao! again,

Brock

Piergiovanni,

The distortion in the 8.5x42 SV EL is complex and resembles the distortion in the Russian BPO 7x30. In the thread below there is a link in my post #45 to photographs of the 8.5x42 SV EL distortion. Holger Merlitz' post # 42 has a link to his description of the distortion in the BPO 7x30. It would be interesting to know whether the new SV EL models use the same form of compound distortion.

Brock,

FWIW, anything I said about distortion vs FOV applied to apparent FOV, not real field.

Hi Brock, thanks for the attention
Like you know, the perception of rolling ball effect is very subjective. Obviously if the FOV is narrow, lower is its perception. Today, by freehand, i thought there was a "little" pincushion distortion, but I have to check with the binoculars mounted on a tripod before confirming this thing. This afternoon I have preferred to see the animals with binoculars rather than do boring test . I would be more technical and precise, but I have difficulty writing in English, i am sorry for this:-C
