See what you shoot, 100mm, f2.8 macro lens is cost-effective. The clarity of this lens is very good. Recently, the shooting distance is small, and you can shoot small flowers and insects and some basic things. It's a little difficult to shoot things like rings, but the size is ok. You can shoot the ring very big, but unless it's the front, if it's 3/4, the jewel of the ring and the ring behind it can't be shot at the same time.

The macro of 60mm and f2.8 introduced upstairs is similar to that of 100mm on 70D camera, and it is also a good choice.

There is also a 180mm macro lens with a frame of 70D, which is not recommended for the time being.

65mm 1-5X, but never used. Just read the introduction. Suitable for shooting small things and jewelry.

EF-S 60 mm f/2.8 USM macro

A compact and lightweight telephoto macro lens specially designed and developed for APS-C EOS digital SLR camera. Converted to 35mm specifications, it can cover the viewing angle of about 96mm, which is very close to the imaging effect of macro lens with focal length of 100mm under Quan Huafu. This lens can not only achieve macro photography from infinity to equal magnification, but also be used as a universal telephoto lens in many shooting fields. The lens structure of the eight-group 12 lens is divided into four groups. Due to the adoption of three groups of floating focusing mechanisms, the lenses of the second to fourth groups will move according to different trajectories when focusing. When taking macro photography, it can effectively compensate all kinds of color differences that are easy to occur, thus achieving high image quality in the whole shooting range. This lens adopts internal focusing mode, and the length of the lens body will not change when focusing. The high resolution can present the details of the subject in detail, and the autofocus speed is also very fast, so that this lens can cope with a variety of shooting scenes from macro to infinity. Because of the annular USM ultrasonic motor, it can always focus manually, and the photographer can freely fine-tune the focus position according to the shooting intention. The optimized lens shape and lens coating greatly suppress the appearance of ghosting and glare. It is a lens with strong backlight shooting performance.

EF 100mm f/2.8L is a USM macro.

A telephoto macro lens equipped with dual IS image stabilizers can play a very good role in macro photography. Based on the well-known EF 100mm f/2.8 USM macro, the optical performance is further improved. With the introduction of waterproof and dustproof structure, this lens has finally become an L-class lens. Dual IS image stabilizer can compensate the translation jitter (jitter parallel to the imaging plane) which has great influence when shooting at close range, such as macro photography, and it can play a strong role in hand jitter compensation with the usual tilt jitter. Therefore, this lens can achieve the hand shake compensation effect equivalent to the shutter speed of about 4 levels at the usual shooting distance, and it can also play a very good role in macro photography where the ordinary hand shake compensation mechanism is difficult to play a role. When the magnification is about 0.5 times and equal times, the hand shake compensation effect is equivalent to increasing the shutter speed by about 3 steps and 2 steps respectively. The lens structure is 12 group 15 lens, among which 1 UD (ultra-low dispersion) lens has good chromatic aberration compensation effect. The optimized lens configuration and coating can effectively suppress ghost and glare. In order to get a beautiful blur effect, the lens adopts a circular aperture. In addition, you can also buy tripod rings sold separately, and you can experience professional macro photography. The maximum magnification of the lens is about equal times, and the nearest focus distance is about 0.3 meters. Equipped with annular USM ultrasonic motor, the focus is fast and quiet, which can realize full-time manual focus.

Although this lens is waterproof to some extent, please try not to get wet when shooting in rainy days. ※.

Ef180mm f/3.5l USM macro

A telephoto macro lens with a focal length of 180mm can also shoot the subject at close range. It is suitable for photographing inaccessible objects such as insects and small animals, and can also enlarge the blooming flowers on branches. This lens can shoot from infinity to constant magnification, and the constant magnification shooting distance is about 0.48 meters, which is longer than other Canon macro lenses. Moreover, the longer focal length makes the blur bigger and smoother, and it is easier to avoid the messy background and make the picture look clean at a relatively small viewing angle. Because of the internal focusing mode, the length of the lens body will not change and the front end of the lens will not rotate during focusing. Through the floating focusing mechanism, the second group and the third group of lenses will move according to different trajectories according to the shooting distance, so as to compensate the unique chromatic aberration of the macro lens and realize high image quality in the whole shooting range. In addition, this lens is also equipped with three UD (ultra-low dispersion) lenses, which can reduce the chromatic aberration that is easy to occur in telephoto lenses. The whole picture has even resolution, good contrast and high definition. Moreover, it conforms to the color expression of L-level lens and can vividly present the subject. A longer focal length is easy to blur the foreground, which can show a different taste from a macro lens with a shorter focal length. If used in a wide scene, the photographer will not feel that the focal length of 180mm is too long, but will actually feel the convenience of this telephoto macro lens.

MP-E 65mm f/2.8 1-5X macro photography

You can use a special lens for macro photography to enlarge the subject by 1 times to about 5 times. It can image a microscopic world that ordinary macro lenses can't capture. It is not only suitable for shooting close-ups of small insects, but also suitable for shooting small pieces of jewelry. The lens adopts three groups of floating focusing mechanisms, which can make the three groups of lenses move independently and effectively compensate the aberration caused by magnification change. Moreover, this lens adopts UD (ultra-low dispersion) lens, which can largely suppress all kinds of chromatic aberration that leads to low image quality at high magnification, thus achieving higher image quality. It is compatible with TTL photometric automatic exposure with an amplification range of about 1 times to 5 times, and it is easy to get almost the same feeling as conventional shooting. When focusing, although you can only focus manually, the touch of the focusing ring is quiet and stable, and you can operate it finely. In addition, due to the detachable tripod ring, the optical axis will not shift when switching between horizontal and vertical shooting positions, so that photographers can switch between horizontal and vertical shooting with confidence. The wonderful macro world of equal or more times has greatly exceeded people's visual range. Using this lens can bring fresh discoveries and surprises to common themes.

The focusing distance is limited to the macro field of view, so it is impossible to shoot at infinity in structural design (the shooting distance is about 0.243-0.3 13m). ※.
