Macro Photography Equipment – Choosing Extension Tubes
Extension tubes are an economical way to start your macro photography journey. These extension tubes have no optics in them and are hollow ring adapters that fit between your DSLR and your lens and they allow you to go beyond the minimum focusing distance of your lens. This basically means that you can get closer to your subject without losing focus and this will ultimately have the effect of magnifying your subject.
However, there are some downsides to using extension tubes. One major downside is that the amount of light that hits your camera’s sensor is reduced. Secondly, you will lose the ability to focus on infinity.
These tubes can be used in combination with any lenses, however many macro photographers use them in combination with a macro lens. When coupled with a macro lens, this will achieve a magnification that is greater than the 1:1 magnification. This will allow the photographer to take a closer shot of the subject.
Extension tubes are easy to use and can be purchased as a set/kit from photography stores. They often come in a set of 3 tubes – each one with different lengths. Before you purchase your extension tubes, it is important to know about the different types of extension tubes.
1. Macro Photography Equipment – Manual Extension Tubes
Manual extension tubes are not designed with any circuitry or mechanical coupling components in them. This means that you will lose the capability to auto focus and auto TTL exposure on your camera. As such, these are generally the cheaper type of extension tubes. For most macro photographers, this is not a major issue as they are manually focusing.
2. Macro Photography Equipment – Auto Extension Tubes
Auto extension tubes are designed with the circuitry and mechanical coupling components in them. When using the extension tubes in combination with the lens, the auto focus and auto TTL exposure functions will be maintained.
When purchasing an extension tube set, ensure that you choose one that has a compatible mount to your camera brand eg. Nikon mount, Canon mount, etc. Otherwise, you will be disappointed as you will not be able to connect the tubes to your camera and lens.
