Hello, I recently bought a second hand Tamron 17-70 from MPB and a have a small problem. The zooming is smooth from 17-35 but after 35 it becomes harder to zoom. Is a problem with my lens or is a common thing with the model? I had several other zooms, and they were smooth throught the zooming range

Hello, I just bought the viltrox 85mm f1.8 and when I checked the details from a jpeg I saw that the maxim aperture is f1.7 Why would this info be in there? So the f1.6 "update" might be true?

Hello, I bought a x-s10 with 7k mechanical shots and 12 electronical. After I updated the camera from 2.6 to 3.11, my shutter count reseted to 0. Is there a way to go back? The updated might caused that?
