Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Contemporary

Practical, comprehensive, refined and elegant.

Cheap, because the price is not high, some people think it is not tall enough.

The third generation of Shima 18-200 is a lens that amateur photographers deserve to own. 1. The comprehensive coverage of the focal section can basically go all over the world in a single lens. There is also a macro, and the zoom ratio is reasonable, at 11.1 times. If the lens is larger, it is basically a mobile phone lens. The image of the monitoring lens is level. The image taken by Nikon 18-300 is basically the level of the monitoring lens I have used. 2. Fine workmanship, Shima C-standard lens, 3. Fast and accurate focusing, which has reached a new level People with the S C standard old Shima lens should try it. Shima lens is really great. Now the new lens is tuned with the 46 megapixel A1 system. If you install it on the camera, it can basically be said that there is a problem with your camera. Of course, Nikon 3200330052005300 is a plastic body, and its deformation and defocusing are normal. 4. The resolution is very high, The reading at 18 80 135 200MM reaches 2800-3000 lines, while other lenses in this focal section are basically 2000-2500 lines. A shot that goes around the world should be well done at present. 2200 yuan is worth it. It beats Nikon 18-140 and 18-200 completely. I used my 8000 yuan Tenglong 70-200A009 to compare it with the Nikon D7100 on the tripod. The film was basically the same, while the Tenglong 70-200 was slightly moistened in color. But if it was done in the later stage, the third generation of Shima 18-200 would be more sharp. Indeed, these can be ignored, because photography is originally for fun. Some people who drive small cars think that driving large container transport vehicles is a pleasure, It's really tall, and it's really suitable for me. It's light, low-key, practical and elegant.

Sophisticated workmanship, relatively low volume and weight, relatively convenient carrying, relatively good imaging quality, resolution meeting certain requirements, color has the feel of art lens, with Canon 600D, focusing accuracy, 600D with their own lens often out of focus, but with this lens is quite good, large zoom ratio is really convenient in practice, no need to change the lens, In addition, the anti shake effect is obvious, the lens coating is better than the socket head, and the feeling is obvious under the backlight.

When the lens is placed vertically, it will slide out or retract by itself, with certain distortion. The focal length of the long focus end is slightly insufficient, and the ratio between the wide-angle end and the socket head is also insufficient. The focal length of the lens is about 19~180 (about 5 meters for the subject). At the long focus end, the focal length of the lens will change when focusing objects of different distances.

Good value for money, practical and convenient, and the imaging quality is obviously better than that of the socket head.
