Hi to everyone !!!!
I would like to share something about optics with all of you.
At the beginning in the early stage of production all binoculars are almost the same, the optical designers for an specific model has an overall idea of the instrument that they want.
They play with powerful optical software to get what they want, changing kind of glass lens ratios etc etc.
The seven SEIDEL aberrations comes then into play and how to deal with is the job of the optical designer.
Seidel aberrations are 1 spherical aberration.
2 sharpness errors.
3 coma
4 astigmatims.
5 curvature of field.
6 distortion.
7 CA longitudinal and lateral chromatic aberration
3 CA
HERITAGE
Every manufactures has strong points that make them famous for.
Zeiss has been famous always for his superb sharpness on center of FOV, bright optics and big FOV.
Now there is a huge discussion about who is sharper, more defined,brighter etc etc.
As photographer i can say......it doesn't matter !!!!!!!
what makes good or better Desing is the character of optics, if SF is a little bit softer or lowest in contrast is nor a FLAW is the character of optics given by Zeiss to enhance other strong point as maximum brightness who affect in some degree to contrast and less definition in order to give a more gentle and realistic view very pleasant to the eye, as also Binomania says on his review.
Optical computation is very very difficult always a compromise, Zeiss go for a very realistic view, so a harsh view was not the goal for the optical team.
Is worse ? NOT, is the designer decision thats all.
Leicas has a very Harsh view ? well they boost contrast, sharpness and definition in order to get it, a very shocking view just because if the heritage of their optical designs also in photography. Sharp transition from in focus to out of focus areas in order to give a great separation subject and background.....the same can be found on his binoculars.
Are better than ZEISS....really not, just different some people will like some not.
PHOTOGRAPHY world.
Binoculars are peanuts.....A leica M lenses goes from 2000 till 11000 euros and Zeiss from 1000 to 5000 euros.
On photography forums there are fanboys of each brand and everybody refers to reviews to talk about optics but i never never found the fanatic loyalty to a brand like here, ZEISS is the best and thats all.
Any kind of discussion is not possible........COME ON !!!!
First think to do is try by yourself, in photography is very easy to make a photo with a lens and review it on big hight quality and calibrated monitors, with binoculars is not so easy.
Zeiss is able to produce THE BEST LENSES ON DSLR world today with his OTUS line, ultra sharp,contrasty, with great definition and the lowest CA on market.A clinical lenses design for studios and comercial photography.
Also has another line like the Sonnar design who has a more gentle rendering very realistic and able to pick up details on shadows for a good B&W conversions............
This kind of character can be found also.....YES ON SF BINS !!!
