How to Compare Camera Lenses:

• Make certain the compared camera lenses actually fit the type and model camera. Many cameras have screw mounts where others offer a bayonet type mount. Many cameras don't have removable lenses at all
• Consider the type of photography when comparing camera lenses. The lens is responsible for the effect on an image so pair the lens with the scene. Landscape shooting requires a wide-angle lens, whereas a portrait lens uses a shorter focal length
• Try out each lens on the camera body and take a few test photos. Reputable retailers allow photographers to bring in their cameras and mount the lens before buying
• Compare apples to apples when buying camera lenses. Higher quality lenses are more expensive and typically yield brighter, crisper images due to better construction and higher quality materials. If the deal looks too good to be true, it probably is
• Understand that many camera lenses that work with 35mm cameras will not work with newer DSLR cameras. The 35mm lens systems use a different focal length for the full frame of film. Most DSLRs utilize a smaller image frame than 35mm cameras so the image recorded is adversely affected

How to Repair Threads on a Lens:

• Cut a strip of wood that is narrower than the inside diameter of your lens. Round the end of the wooden strip using your jigsaw and wood rasp. This tool is your punch

Instructions

• Place your lens cover on your wooden board, so half of the lens cover is off the side of the board and the rest is on the board. Allow 4 inches of board on either side of the semi-circle created on the board with your lens cap. Mark a pencil line on the outside of the semi-circle and remove the lens cap
• Cut out the semi-circle marked on the wooden board
• Smooth the semi-circle cut in the wood with coarse sandpaper or a wood rasp. This tool is your camera stabilizer
• Cut a strip of wood that is narrower than the inside diameter of your lens. Round the end of the wooden strip using your jigsaw and wood rasp. This tool is your punch
• Place the lens on the lens stabilizer, dinged side down. If necessary, ask a helper to hold the lens in place for you
• Insert the rounded edge of the punch against the lens thread ding. Pound on the flat end of the punch to press out the bent portion of the threads
