Another Tele-Lens Using:------
I have been sold out my Kenko 8X32 , felt missing somthing,so
I trying to get another tele-lens,but not so much tele-lens to choose,so
I decided to try another unknown lens.finally I found some lens have a
clear,sharp,less vignetting,and more magnifying.here was my experiment
of using these lens.
The first lens was monocular 10X50.made from Russia.I used my hand-make adaptor to attach my CP990.The image quality was sharp,little bit chromatic aberration,CP990 zoom to F2.8(below have a table that describe the zoom range)would no vignetting.
Below photos was taken by CP990+10X50 Russia monocular.
The second lens was Minolta standard Binocular XL 10X50W (this lens was not Activa.this was old model,I could found out in some shops).I cut this binocular by saw to changed to monocular(I'm crazy),and also used my adaptor attached to my CP990.This lens image quality was sharp. little bit chromatic aberration.CP990 zoom to F2.6(below have a table that describe the zoom range)would no vignetting.
Below photos was taken by CP990+Minolta Standard XL 10X50.
The third lens was Minolta Activa 10X50W binocular(this
new model was replaced Minolta Standard XL 10X50W),I also cut this binocular
as a monocular too.and same used my adaptor for attach to my CP990. the
image quality is sharp but not better than Minolta standard XL 10X50W,and
have many chromatic aberration .so I gave up this lens .....sorry have
no photos to demo
The fourth lens was Canon 15X50IS binocular,.because all the previous binocular have been cut off,and I actually want a normal binocular for watching star,so I choose 15X50IS,this lens have image stabilizer,good for watching star without using tripod(also good for taking tele photos without using tripod).Oop.... this time I would not cut this binocular.but of course I would not gave up to used this binocular for taking photos,so I made a mounting plate for connect CP990 to this binocular.this lens quality was excellant.sharp to edge.better than all binocular and monocular I have been used.a little bit chromatic aberration.CP990 zoom to F3(below have a table that describe the zoom range)will no vignetting.
Below photos was taken by CP990+Canon 15X50IS Binocular.some photos was using image stabilizer because shutter was under 1/30

|15X50IS lens no
How to made the adaptor?
This have been described in my ETX page.(but this only for reference)
Why I choose Minolta 10X50W XL binocular?
Because 10X50 have a factor of 5 exit pupil.this will gave more light to digital camera,and also this binocular have a wide angle eyepiece,the eyepiece glass diameter have 23mm.this would cause less vignetting.
10X50W XL eyepiece compare with normal binocular.
How to fixed the eyepiece?
Because of cutting Binocular into two parts,one part eyepiece mounting is broken,so the eyepiece will drop freely.I used three small screws to locked the eyepiece.
and also I made a tripod mounting at another two cutting part
Can CP950 work with all this
Yes,but the vignetting would be different with CP990.My friend have been taken the other part of binocular for his CP950.
Was this lens easy focus?
Yes,I used Macro mode could focus at all zoom range.
Oh.....,I have been spent much money.give me a break. If I have more tele lens using,I will update my page.Thanks.
