This lens I believe is quite remarkable for a low end Nikon product. When I am ready to shoot with the shutter button
pressed half way, the optics jump upwards and without taking a photo, jump back down when I remove my finger.
I did call a local camera service/sales shop and they had never heard of this happening, but suspected that the auto-focus
may very well be the culprit. I suspect that the optics may well have separated from the adhesive, and that is not good for anyone.
Again, I have no complaints regarding the IQ and overall performance of this lens.
Thanks for reading and for any feedback.
Adios,
TT
