This is body only so you'll have to get one or more lenses.

I now shoot Nikon, the video is not as highly specced but for what I do, soooo much easier to handle.

Have a look at this video , explains it better than I could.

Your issue sounds like it could be a dirty solenoid , I worked with a buddy of mine and we cleaned the solenoid surfaces using fine grit emery cloth to remove the pitted marks instead of replacing it , worked very well , going on 3 years with no issue.

You can shoot in a log or flat profile but this takes skill in shooting, exposure is critical.

This is insanely cheap, but I still wouldn't buy it again.
