I gave away the Nikon 55-300mm lens on 07/12/2023. Of the faults identified at the time of the first diagnosis: autofocus does not work, part of the bayonet is broken off. Malfunctions that were missed during diagnosis: the gearbox does not work (noticed after ~ six months).
The first reason why I would not advise anyone to contact this service:
For the entire time the lens has been in the service, I have never been contacted, there is no feedback. I had to call myself, pull and find out how the repair was progressing, whether any details were needed. It got to the point that on another visit to the service, I asked the question: "Is this the norm that you promise to call back, and as a result, I call you myself after a fairly long number of days?", after which the admin (later it turned out that this was the director) pointedly pasted a piece of tape on his laptop, writing on it the order number. But even after that, they didn't call or keep in touch.
The second reason:
For all manipulations with the lens, the amount was 250 rubles. Of course, they didn't have spare parts. I handled the purchase. At the very beginning of the "repair" it was indicated that you need to buy an autofocus motor. They didn't find it in stock in Minsk, a service employee showed "how it looks like" and pushed the purchase from ebay onto me. ~ a month after the last dialogue, when I called again (I called again and asked how things were going), it turned out that there were not enough gears in the gearbox (why was this not revealed at the diagnosis?). I brought the gears, which, as a result, did not fit. Then there was the question of buying a new gearbox. We wrote off in Viber, they replied to me "the gearbox in the photo looks like it's from the right version, it's hard to say 100%." I ordered it. I took it to the service on 04/09/2024 (it turned out that there is an autofocus motor included with the gearbox, that is, it was possible not to order it separately). They said that everything would be ready by the end of the week, but again no one called. At the end of the week, I typed it myself, the answer was: "Nothing is ready yet." To the claim that they promised to do it by the end of the week, and why call the deadlines if you don't know yourself, they replied: "We have a queue here, we don't know when we will do it." And then, on 04/18/2024, for the first time I got a call from the service. The gearbox did not fit! They offered to take off the photo of the necessary one so that I could re-order (and why couldn't I initially take off the photo if they themselves are unable to sit down and find a suitable gearbox?). No one knows what kind of spare parts they are or what they look like. 04/19/2024 I came to pick up the lens from this mountain service, the admin director sat down to look for the right gearbox, but something went wrong and I heard the same phrase again that they wrote to me in Viber: "It's similar, but it's hard to say 100%."
The third reason:
Apparently, the lens was engaged only after my call and questions when it was already repaired. The lens has been in service for 9 months!
The fourth reason:
04/19/2024, when I arrived to pick up the lens, the disassembly began what how and why, in the end the admin director said: "I don't want to talk to you right now, take the lens and go, go where you were going." Customer orientation is minus 100 points, a boorish director who sincerely believes that he is right.
And finally... When I started checking the lens before signing the act of completed work (in which, for a second, there was not a single written line, logically they did not do anything at all, did not disassemble, did not put the motor, etc.), it turned out that manual focusing did not work either (it worked without problems before the "repair"). He said that it was necessary to fix and give the lens in the condition in which it entered this wonderful place, to which the administrative director replied: "Replace the gearbox, you wrote a complaint in the book of complaints and suggestions, now I won't do anything after that." That is, if I hadn't written a complaint, then they would have fixed it.
There was no answer to the question whether the autofocus motor was changed or not, they argued that a lot of time had passed and he did not remember (but it should have been spelled out in the act), the admin director called the master, who also did not kick in the tooth: "Well, it seems like it's worth it."
As a result, the lens was broken. If it were possible to put 0 stars, then I would.
Colleagues recommended this service, they said that Nikon is being repaired well here. I gave it away - we did it)) And they gave me some advice. Even when I was there, the girl brought Canon, they also said they refused everywhere where she called, but they accepted it here. And they also have an interesting book with competitive photos of Belarusian photographers.
