This place was very nice to go to and my product that I got was very high end and the workers there were incredibly helpful in terms of helping me choose the right product to get. Furthermore, this location in manhattan was very convenient and near my work place and the atmosphere was very friendly. I do recommend ever to get their tech products here as they are again very high quality and very nice to work with. I bought camera lens for my nephew as well and he also said it was very nice and easy to use.

As good as its reputation

I was very interested in this lens when it was released and the reviews were so good. I really had no reason to buy it because I already had the Viltrox 27 1.2 Pro and the Fuji 27 2.8 ver. 1. The external AF mechanism recently seized up on the old Fuji 27 and I suddenly needed a replacement. I use the Viltrox Pro in specific low light situations, bad weather and at night. It’s too big and heavy for me to use as an EDC lens. I looked at pancake lenses, but kept coming back to this one due to its reasonably small size and low weight plus the benefit of optics capable of producing sharp and contrasty images at F1.7.
