Why are Zeiss so sharp on-axis compared to other binoculars? (1 Viewer)

red is looking weird because of TFL has distictive greenish coloring.
on the other hand, bino with reddish coloring auch as shuntu panorama, kenko ultraview tends to make green color less vibrant.
I think it does it because green and red are complementary colors

LEFT : Zeiss victory HT 10x42 (bit greenish - bluish coloring. But much less green bias then TFL
RIGHT : Shuntu Panorama 10x42 (Distictive red coloring)

Wow! Big difference. I prefer the HT on the left. It looks more natural to me. I wonder if the Shuntu is like a Leica. It has a lot of red saturation.
 
Is that greenish tint found on the 7x42FL produced later with lototec (and distinguished by having an underscore on their 7x42?
Denco which do you have?
My Zeiss FL 7x42 are lototec and my Zeiss FL 8x32 are pre-lototec. I just had my FL 7x42's outside and I really don't see much green tint. They are sensationally good binoculars. Great DOF, easy eye placement and brightness in low light.

The 7x42 FL is excellent except for the reds looking weird. I have said this before I know but when compared side by side with the 7x42 Leica HD I prefer the color in the Leica. Everything else about this Zeiss though is awesome.
Leica's have a lot of red saturation. Similar to the Shuntu as in jackjack's picture.
 
I suppose we know these results are interesting, and they are subjective to the reviewer.
Testing like this is very difficult, sample variation, lighting differences, etc. That is why
you don't see it done, in a real standard, hard to measure and all of that.

Jerry, I think you have a less-than-sign to right of 'M' (shift-apostrophe).

"EDG < SF < NV < HT < NL < EL (8.5)"
I assume this means EDG is less-than SF which is less-than NV, etc. Less-than meaning less sharp or whatever.
I only use laptops, limited keyboard options. Or limited by my knowledge of how to use it. :)

Jackjack. The picture on the right seems to be sharper than the picture on the left. Do you have any ideas why? Thanks!

much more red then leica.
like typical cheap chinse bino.
leica is more like orange and amber because of additional yellow coloring with red. but panorama is almost pure red - brown
 
Jackjack. I really like your sharpness testing and simple to understand ranking. Would you have ideas why the EL is sharper than the NV, for example? Thanks!
maybe because Extended FOV?

NL has better color satuation but el has bit higher sharpness.

but due to large difference of color saturation, NL's additional color contrast made it's resolution to overcome EL at long distance viewing (about 200m) and at bad atmosphere
 
Jackjack: In your sharpness rankings where would you place the Swaro. SLC? I am particularly interested in SLC vs EL. Thanks.

unfortunately I have only seen 15x56, 10x56 SLC
no same apature with EL.
but it was sharper then I thought it would to be
well enough to call it Alpha sharpness.

Above : TFL 10x56 (Lotutec ver)
Below : HT 10x54

You can see the color difference.
TFL has bit of greenish, mintish tint. and HT has less green but more bluish tint.
(easily shown at first photo)

color fidelity and overall color contrast is well improved at HT

but like the second photo, greenish objects are more vibrant on TFL because of greenish tint

7x42 TFL I seen had similar color bias like 10x56.
10x54 HT's color fidelity is bit better then 10x42 HT (more blue, less green) and bit worse then 8x42 HT and 8x40 SFL

JJ, with ref. to posts #311-312: As you have placed Swaro. EL at the extreme in the sharpness list it will be interesting to know where you place the SLC, should you get a chance to test one. A friend and I compared the two ~10 years back. He's a meticulous observer of binocular imagery (and of birds). His visual acuity and mine I reckoned were 20/12 and 20/15; the latter is common on BF. There were 1 SLC and 2 ELs, either, 8x42 and 8.5x42, or both models 10x42, afraid I cannot remember. It was in tropical daylight. Clear, a little, somewhat, cloudy -?-again, memory! Effective /apparent /functional sharpness in the open was no different to each of us. Within foliage in shade he could see more detail with the SLC, very slightly, but definitely. (I could not, or, not trying, or observant, enough, did not, see a difference.)

I also heard really good word about SLC between Korean mania to.
some say that they are EL without field flattener :)

I have compared SLC 10x56 vs TFL 10x56 and found out SLC leads at central sharpness and color contrast.
so I'm really eager to see 42mm SLC myself

unfortunately, 42mm SLC is REALLY rare item in Korea because they don't lasted long on Korean distributor shop...
It only showed in Korean market just a couple of time and only a half a dozen member I know have owning or own SLC 42mm

but SLC 10&15x56 is at the shelves until now so many of the Korean members have it. especially 15x56.

Typical cheap Chinese binoculars have a lot of red saturation? Interesting. Thanks. :)

You're correct. I can see the difference in your pictures. The EL is sharper, but the NL has more saturated colors. Nice pictures!

Yes, I see the difference. I wonder if the HT color is bluer to enhance lowlight performance. I kind of like the blue sky in the HT picture a little more than the FL, but I wonder if it is a little over saturated and the FL is more real. Do you take these pictures from buildings?

Good observation. I wonder if he could see in the foliage shade better with the SLC because of it's higher transmission than the EL. Thanks for the post.
