Extension Tubes & Close Up Filters: How To Get Into Macro Photography on a Budget

Whether you are brand new to the world of photography or if it has been a lifelong passion, you will be familiar with macro photography images, whether you know it or not. Those detailed images of bugs and flowers that are always eye-catching are the champions of the photographic world, and as we will discuss today, there are more ways to achieve great macro photography than expensive camera gear.

Understanding Macro Photography

The best macro photography involves capturing the smallest details of the world in remarkable detail. Rather than standing back and letting the full story unfold, macro photographers get as close as possible so they can highlight specific elements.

Macro photography is perfect for artistic explorations, but it is also crucial in science and medicine/dental fields as it allows for the precise magnification and capture of intricate details, enabling accurate documentation, diagnosis, analysis of pathologies, monitoring of treatment progress, and enhancement of both professional education and patient communication.

Macro photography is a unique field in that it requires a specific set of technical skills to succeed, such as mastering composition and the right camera techniques, but you are also reliant on possessing the right camera gear — not just any old camera will do if you seek the best possible macro images.

Using Dedicated Macro Photography Gear

If you want to compete with professionals and produce macro photography works that can be presented as artworks on the gallery wall, generally you will need to rely on dedicated macro photography gear. This includes general items like a tripod and a high-quality camera, but mainly relates to your lens choice. Dedicated macro lenses are the be-all and end-all when it comes to producing brilliant macro photographs.

Macro lenses are ideal for macro photography because they are specifically designed to achieve high magnification ratios, typically 1:1 or greater, allowing for life-size or even greater-than-life-size reproduction of tiny subjects on the camera's sensor. Their optical construction minimises distortion and aberrations at close focusing distances, ensuring exceptional sharpness and detail. Additionally, macro lenses often feature a longer focal length, which provides more space between the lens and the subject — crucial for lighting and composition when working with small, intricate objects.

What Are Extension Tubes, and How Do They Work?

If you are on the hunt for a more affordable way to immerse yourself in macro photography, extension tubes are one option that you should consider. Extension tubes are a hollow tube mounted between your camera lens and camera body, which extends the distance between your camera sensor and the optics of your camera lens. The benefit of this increased distance? It grants your mounted lens increased magnification and helps it achieve a closer minimum focus distance — two features that dedicated macro lenses also possess.

Pros of extension tubes:

• Cost-effective
• Maintain the optical quality of the lens
• Stackable to adjust magnification

Cons of extension tubes:

• Results in some light loss — requires adjusting exposure settings
• Loss of infinity focus
• Certain models result in a loss of electronic communication or function

What Are Close-Up Filters, and How Do They Work?

Close-up filters are an even more affordable way to try your hand at macro photography. They work just like any other camera filter and screw to the filter thread of your camera lens. Once again, close-up filters are an accessory that increases the magnification and reduces the focus distance of your camera lens.

Pros of close-up filters:

• Easy to use — screw to your lens within moments
• Universal — will function on any lens with the correct filter thread size
• Very affordable
• Ultra-portable

Cons of close-up filters:

• Can degrade image quality
• Stacking makes image quality loss even worse

Will These Budget-Friendly Options Do the Job?

So now you're wondering — will these budget-friendly macro options help you on your quest to master close-up photography, or do you need to go all out and invest in high-quality macro photography lenses? As always, it's best to take the horses-for-courses approach:

• If you just want to experiment with macro work, picking up some close-up filters is a fun and cheap option.
• If you want to capture some great macro shots but don't have a huge budget, extension tubes are the perfect choice.
• If you want to push your skills to the limit and hope to be taking out first prize at your local macro photography competition, you will eventually need to invest in the best macro photography lens that you can afford.
