...Legat de acea usurime cu care se misca mecanismul focuser, lucru ce vad acum si din celelalte rapoarte ca e ceva obisnuit la Zeiss... |
Cautand una am dat peste alta! Acest mod ultrausor de deplasare a mecanismului ce realizeaza focusarea imaginii nu este un defect de constructie, nu este o scapare, o greseala a celor ce au proiectat mecanismul, nu este nici macar o dovada a slabei calitati ce ar putea apartine in acest caz Zeiss-ului....ci pur si simplu toata chestia asta a fost facuta anumit, cu intentie! 🙂
De ce? Raspunsul celor de la Zeiss este: microreglajul.
Am comparat apoi Zeiss-ul cu un binoclu mai butucanos in acest sens, ce necesita ceva forta ca sa misti rotita mecanismului de focusare.
Rezultatul? In timp ce la Zeiss poti regla la sfert de liniuta imaginea cea mai buna, la binoclul ce opune o rezistenta mai mare a focuserului se intampla urmatorul lucru: in momentul in care forta mainii a invins rezistenta rotitei de reglare, adio microreglaj.

De mult timp imi statea pe cap problema cu defazarea focusului pe cele doua tuburi, azi am zis sa il desfac, aveti doua poze, eu am rotit piesa mobila de la stanga la dreapta, atat, pare rezolvata problema...cel putin asa pare bine. Referitor la micro reglaj....porcarii, este un o-ring pe ax pe care strange rotita, trebuie un o-ring mai gros ca sa stranga mai tare. Per ansamblu o lucrare made in china, cu piese din plastic si dimensiuni mici, de ex la Bushnell binocluri mult mai ieftine au tot mecanismul din metal, nu se compara, astia la 6000 lei pun plastice, si mai tot zicem de binocluri chinezesti ca nu is bune...astea is mai bune...

Suna a cosmar sau a ghinion ...?
| Citat: | | My story begins a few years ago when I bought my first binoculars from Zeiss, the Conquest HD model in 10x42. I received the binoculars at home from a very respected dealer in Europe, but unfortunately, the focus wheel was unusable and also decollimated. I returned it and received another one with the same problems, and this situation repeated itself five times! I received five defective binoculars. Finally, I received the sixth one, and it was decent. The alignment was perfect, but the focus wheel was still not working smoothly. After one year of use, it began to work even worse, so I decided to send it to Zeiss in Germany for repair. They confirmed that the binoculars had alignment problems, problems with the diopter adjustment, problems with the focusing mechanism, and the hinge was loose. After one month, I received the binoculars, and unfortunately, now there was something rattling inside, the hinge closed by itself due to its own weight after 2-3 IPD adjustments, the diopter adjustment had to be made separately for stars and nearby objects, and the optical tubes didn't enter focus simultaneously. I sent the binoculars back to Zeiss again, at my own expense, and they confirmed all the problems and replaced the binoculars with a new one. Just a few days ago, I received the new binoculars, and unfortunately, it was decollimated. I'm writing this experience so that those who want to buy a Conquest HD should think twice and also consider other options. Has anyone else experienced something like this? |
Bafta!

Mesajul citat de Zoth, este chiar mesajul de pe birdforum al lui Daniel (colegul nostru). Am avut in mana unele din Conquesturile lui si pot confirma cele spuse de Daniel. In schimb exemplarul meu nu avea probleme de focus... Dar cu o floare nu se face primavara

Da, eu am trecut prin asta si eu am scris mesajul pe birdforum.
