1. What is Macro and Close-ups Photography ?
It refers to taking close-up pictures of small things.
2. What is difference between Macro and Close-ups Photography ?
Macro refers to 1:1 or beyond.
Close-ups refers to the object looks closer but larger than 1:1
3. What is 1:1 Macro Photography ?
The image projected on the "film plane" (i.e film or a digital sensor) is the same size as the subject. On 35 mm film (for example), the lens must have the ability to focus on an area at least as small as 24×36 mm, as this is the size of the image on the film. This is known as "life-size magnification" or simply 1:1.
4. What is 100% crop ?
It is viewed or displayed at the original resolution. Usually displays part of an image in 100% crop.
5. What is the recommended macro camera equipment setup ?

6. What is a dedicated Macro lens
It is specialised lens for macro photography and capable to take up to real life size (1:1). It also can use as normal focal length lens.
e.g.
- Canon 50mm macro, Canon 100mm macro, Canon 180mm macro
- Nikon 105mm macro, Nikon 200mm macro
- Sigma 50mm macro, Sigma 105mm macro, Sigma 180mm macro
- Tamron 90mm macro, Tamron 180mm macro
7. What is a close-up filter ?
It is an add-on lenses, works more like a magnifying glass which you can screw it onto the end of your lens on the filter threads. Such filter allows you to move much closer to a subject than you normally can, permitting macro photography at the cost of some image sharpness. Cheap closeup filters have only one glass element and thus are very vulnerable to chromatic aberration. Better closeup filters have two elements.
The focusing distance is mainly depend on the diopter value of the close-up filter and not the focal length of the lens. See below focusing distance calculation:
+2 close-up filter will give about 1000/2 = 0.5m
+4 close-up filter will give about 1000/4 = 0.25m
+5 close-up filter will give about 1000/5 = 0.2m
+10 close-up filter will give about 1000/10 = 0.1m
- 100mm with +2 close-up filter
- 200mm with +2 close-up filter
- 300mm with +2 close-up filter
- 400mm with +2 close-up filter
All above setups will have same or similar focusing distances but the magnification increases when focal length increases.
e.g.
- Hoya Closeup +2 or +4
- Canon 250D or 500D (expensive but give better quality and lesser distortion)
- Nikon 4T, 5T or 6T (expensive but give better quality and lesser distortion)
- Raynox DCR-250 (expensive but give better quality and lesser distortion)
8. What is an extension tube ?
It is a hollow tube (no element) which mounts in between the lens and camera body. The purpose is to move the lens farther from the film or digital sensor. The farther away the lens is, the closer the focus, the greater the magnification, and also the greater the loss of light. When a lens is focused at infinity, its maximum magnification is the length of the extension divided by the focal length of the lens.
The focusing distance is depend on the focal length of the extension tube and the focusing distance of the lens.
e.g.
- Canon, Nikon or other brand original extension tube
- Kenko DG Teleplus Extension Tube Set, 12mm, 20mm and 36mm
9. What is focusing and working distance ?
Focusing distance is the distance between the sensor plane to the object.
Working distance is the distance between the lens front element to the object.
