Macro photos are a favorite of mine, and a lot of people enjoy taking them. They provide a unique perspective into the world, and it’s especially fun to find something to photograph in and around the house. The Canon 250D Close up filter is actually a double element close up lens. It is of excellent build quality, and is not to be confused with some of the cheaper close up filters on the market.
The lens itself has a metal frame, and is quite heavy. It comes packed in a pretty clear round case with a screw on cap. The cap can come loose if not put on tightly. The Canon 250D and 500D close up lenses work by screwing on the front of your lens the way a filter does. They then reduce the closest focusing distance of the lens. So say your lens normally can only focus as close as 1.5m, with one of these filters attached you might be able to focus as close as half a meter.
The quality of the optics is actually very good. These are better than the +1, +3, +5 type filters you might find online, or in stores. Those tend to be single element lenses and will distort the picture more. Edge sharpness will especially suffer with those lenses.
When shooting with the close up filter you will tend to have a very narrow DOF. That is very thin area in front of your camera will be in focus. If you imagine a photographing a ruler flat on a table from a 45 degree angle maybe only a few mm of that ruler will be in focus. So it’s very important to use a tripod or have a very steady hand. You will often want to shoot at f10-22 to put more of your subject in focus and thus requiring even more light.
This is a great way to get into macro photography. You can stick the 250D on a good quality medium zoom and have a pretty macro lens. The 250D is recommended to be used on lenses in the 28-135mm range, while the 500D is meant for 100mm-300mm lenses.
