Shipment 5 days !! A real super set,

To The Product:
it's all very high quality, made of sturdy aluminum, paint does not flake and it is processed very clean, no burrs, no defects.
The adapter: the part where the 2 set screws in it is easy to apply (see below!)
The Tele-extension (the 2nd metal tube that is for Tele APPLICATIONS to screw), as well
there are 2 filter this: a pole filter, which I have tested and it works as it should, but darkens the image noticeably - but which is normal in polarizing filters. Ie: increase exposure time and you can really let reflections on windows and on the water and bonnets "disappear".
the UV filter: I have a Nikon Coolpix L830 and in conjunction with the UV filter, I have found that at ISO1600 image is more intense at night in lighted streets, so it keeps interfering light waves somehow quite well and looks good as an objective lens protection, because I is not noticed changes in color or distortion, only purely physical, it's just a lens more front of the sensor. Everyone needs to know yourself ...
The Geli (Lens Hood) has me one hand angered the other hand, enjoys:
positive that a Einstellkranz lubricant is, so you can turn the shutter once and fix or turn several times and fix the former, if you often from / install, but it fits well and seems to be very stable (plastic)!
Negative but the thread outside: in contrast to the thread on the lens side I do not know what that is for a thread, but the UV filter always plops out! So have the UV filter now between Geli and objective and that holds good!
The lens cap keeps the Geli but very good. The is designed just like the original Nikon, but just slightly larger ..

To install:
In order not to break anything and not to pull the camera mechanics I strongly advise the camera on a foam pad or terry-cloth to put on the screen, beautifully appointed to set up and hold the adapter with the screws and then the two screws both evenly to screw up the resistance is slightly higher, then make time and again the camera on and off, and each time the screw by 180 ° more attracting to the lens stops as soon extends (the mechanical noise is "darker") then turn back the bolt 180 ° and you're done. ..

practical application:
I read that it comes to tunneling / vignetting in WW (wide angle), which is exactly the attitude that the Coolpix has always shortly after switching on without zooming, but when you zoom times falls yes on the lens retracts first and further back again extends: only here ends the WW!
If one removes the additional tube, there is neither vignetting nor the vertices are influenced in some way, not even with filter + Geli. I took a picture once made the WW ends = When will the corners with TELE-top + Filter + Geli no longer be influenced from when. Once everything is removed, you can also use the WW in full extent (see pictures).
The Pol-filter (at times Wiki watch "polarizing filter") screwed to it and turns it until the reflections disappear, just try :-)
The Geli - sometimes mistakenly referred to as "sunroof / sunscreen" - by the way even at night makes sense: because it keeps SIDE irradiating light rays of any kind away ...

CAUTION !!!
If the Geli is it lit, the AF-assist illuminator is no longer the center of the picture! In near-darkness in photos so Geli from or otherwise "AF illuminator" = off!
In wide-angle, the tube ("Tele-Adapter") before mounting rausdrehen since otherwise the tunnel effect!
With telephoto (when much zooms) the Tele Adapter Vorsetzen or use without a filter (that the tube is open), because otherwise the objective lens onto the filter suppressed and irreparably SCRATCH !!! = Camera unusable! But that does not affect the Geli
If you always consider these 3 points, then the whole set of big hit and really a bombastic purchase! I take a picture as the professional Coolpix thus looks, but more importantly again: it does everything it should.

The set comes with 2 round plexi boxes for the filter pad. I under the pad a piece of double-sided tape made, then the pad also keeps and does not fall outside. Also very robust. Lid on it and turn it slightly, then it is too!

Who wants to photograph the sun, because I still nen tip: pick "Astro Solar sun filter foil" 2 cheap UV filter for some buy (not this one, which I think is too high for it), the glass rausdrücken both, foil beautiful plan without tension spread, superglue on the inner rim of the filter (caution the threads do not smear) and carefully place it on the sheet, the edges with carpet knife cleanly sever after few minutes and a filter for the 2nd filter screw (that the film accurately between two filters is) and you've got a super-professional solar filters. Be careful when handling and use, not to take on the film (grease stains are affecting the image) ...
