## Questions & Answers

**Q: After attaching the lens, why it show "Lens not attached"?**
A: Because our lenses are manual focus lenses with no electronic contacts, there may show an error page of “Lens not attached"(Some Nikon models may not show error), please DO switch to “M" mode to use. (The error page will disappear in M mode.)

**Q: Why does my picture out of focus and very blurry?**
A: Manual focus lens need to turn the focus ring for manual focusing, pls rotate the focus ring on the lens to focus. Also, it has no stabilization and autofocus for clear images, you have to spend time on getting the right focus.

**Q: How to do if the image turns out dark?**
A: Increase the ISO and decrease the shutter speed. If the image turns out too bright, reverse the above steps.
