EF 100 f2.8 USM Macro

- Lens Construction (elements/groups): 10/9
- No. of Diaphragm blades: 8 
- Minimum Aperture: 32 
- Diagonal Angle of View: 24 
- Closest Focusing Distance (m): 0.31 
- Maximum Magnification (x): 1 
- AF Actuator: USM 
- Filter Diameter (mm): 52 
Medium telephoto lens with a macro feature for 1x magnification. Fluctuations in spherical aberrations caused by focusing are suppressed, and high-quality images are obtained at all focusing distances. With eight aperture blades, good background blur is obtained even when the aperture is decreased by one or two stops. A focusing limiter which limits the magnification to 0.25x is built-in.

 EF180mm 3.5L Macro

- Lens construction: 14 elements in 12 groups
- No. of diaphragm blades: 8 
- Focal length and maximum aperture: 180 mm 1:3.5 
- Diagonal angle of view: 13- 46 
- Focus adjustment: Inner focusing system with USM 
- Closest focusing distance: 0.48m / 1.6ft
- Maximum magnification (x): 1.00
- Weight: 1,090 (grams)
- Filter size: 72mm
Another telephoto macro lens with a maximum magnification of 1x. Life-size close-ups can be taken from a farther distance without disturbing the subject. The internal floating system minimizes fluctuations in aberrations caused by changes in the focusing distance. The delineation is therefore razor sharp from 1x to infinity.

 EF 50mm f/2.5 Macro

- Lens construction: 9 elements in 8 groups 
- Focal length and maximum aperture: 50 mm 1:2.5
- No. of diaphragm blades: 6
- Minimum aperture: 32
- Diagonal angle of view: 46 
- Focus adjustment: Front group linear extension system with AFD 
- Closest focusing distance: 0.23m / 0.8ft
- Weight: 280 (grams)
- Filter size: 52mm 
Lightweight and compact macro lens for close-ups up to 0.5x. Floating system for superior delineation at all focusing distances. With a large f/2.5 aperture, true and beautiful background blur is possible. Beside macro photography this lens could be used for portraiture and other applications.

 MP-E 65mm 1:2.8 1-5x Macro

- Lens construction: 10 elements in 8 groups
- Diagonal angle of view: 1814'' 
- Focal length and maximum aperture: 65 mm f2.8 
- Focus adjustment: Manual 
- Closest focusing distance: 0.243m 5X 
- Filter size: 58mm 
This is the first macro photo lens designed to achieve a high magnification greater than 1x without additional accessories. It is ideal for small subjects. The newly designed optical formula and UD-glass elements suppress chromatic aberrations which become apparent at high magnifications. For flash photography, Macro Ring Lite ML-3 can be attached to the lens.
