My first time as a Calumet customers. Sent a lens for repair and after two days you sent back to me instead Nikon repair center. After this first issue, as the repair takes too long, I needed to buy a lens (nikon 50mm 1.4G) to use as backup of the lens I sent in repair: you did not want to sell it to me because was my first purchase and you wanted some proof (bills etc). After spending the afternoon at the phone speaking with different people, finally you sold me the lens. Honestly, I don't think I will buy anything from you also if I like your stores and your prices. I am a professional photographer and the first thing i need is reliability.
