Tech Queries: Lens for Sony DSC H5 camera

I have a Windows 7 PC. After deleting some software like Rocketdock and calendar, I get an error message every time I restart - “Error: core library wasn’t found”. How can I stop this message?

First, try hibernating the PC instead of shutting down. Then start the machine up again. If the message does not appear, the problem is that there is a program (most likely from among the ones you deleted) that was set to autostart with Windows. This also means that they were not properly uninstalled. Click Start, type ‘msconfig’ and hit enter. In the window that opens, go to the start up section and disable the startup of the programs you have deleted (uncheck the boxes) — Rocketdock, calendar and so on. Apply changes, restart the computer and the error message should be gone.

Should I buy a wide angle or telephoto lens for my Sony DSC H5 camera? The camera has a 7 Megapixel sensor and 12x optical zoom built in.

With the Sony H5, you can’t really purchase additional lenses like with an SLR camera. However, you can buy wide or telephoto add-on lenses. Sony has some options, but there are third-party brands available as well. Make sure you can try it out on the camera before you buy to see that it works properly.

The one you choose (wide or tele) really depends on what kind of photographs you want to take. If you want to take a lot of indoor photos, landscapes and subjects that are close by, the wide conversion lens is recommended.

The tele add-on can be used for candid photography, for subjects that are far away, for wildlife photography and so on. You can also experiment with various creative filters, that screw on to the front of the lens. Just match the filter diameter to the diameter of the lens.

For complete freedom with lenses — your next upgrade should be a good digital SLR. There are many good options available, at prices starting at `22,000 with an included 18-55mm lens.
