It is so nice to see a small family owned shop instead of these big box stores. I generally felt cared about when getting my blackmagic cinema camera. Love the quality of the images and how easy it is to use.

This small business has the best customer service HANDS DOWN!!
Lucas worked with me diligently to help me find a camera that would fit my needs and that would arrive in time for my trip. I take photos, but wanted a smaller, more compact camera to take with me when traveling. He even reached out to other camera experts to make sure he was giving me the best advice for the equipment that would accommodate my needs!
Lucas was patient with me and was in constant contact with the camera supplier to keep me updated on the status of my order and when the items would be ready for shipment. Once my order arrived to the store, it was in my hands in less than 2 days. I would give 10 stars to this business if I could!!
SHOP SMALL! :)
AMAZING SERVICE!
In short: I was able to receive the black colorway below retail and free next day shipping with the promos that they offered for being a new camera web-shop based from AZ.
Long story: Lucas who is prolly the only rep for the company cuz they're so small is the best dude ever. Since i ordered he responded on emails and updates quicker than some of my friends texting me back about where am at on the list as people just kept cancelling their order. I went from 9th place in line to 4th place in line for the silver. And he hit me up saying that they were still waiting on Fuji to send shipping updates and that no company knows what they get on their weekly fuji shipments other than from a 24 hour window of receiving shipping details.
He then noted that there were two black X100Vs available that were reserved to customers who ordered but have not confirmed. I said if they dont confirm please let me know and ill take that instead of the silver. The next day he hits me saying the customer said to cancel and he sent me an invoice. I ordered accessories for the camera on amazon right after and my package for the camera came before my amazon package. Lucas was super nice and transparent about everything. Dope experience from NUZIRA.
Lucas was so incredibly helpful!!! I’ve genuinely never had better customer service. They offered to stay late so I could get my order and were so patient with all my questions. I would give them 10 stars if I could.
