My ClickBD
The non-USM versions are generally considered very low grade consumer lenses with the USM versions only slightly superior in build quality and 'feel'. None of the versions (USM or not) support full-time manual (FTM) focusing. The optics are similar in the IS USM and USM versions. The USM feature is signified by the gold "Ultrasonic Motor" text wrapped around the barrel of the lens. The original USM lens caps also says "Ultrasonic" although caution is advised as lens caps are often swapped and should not be counted upon as indicative of the actual lens' features. I have brought it from uk. I have hardly used it for 2 months. contact me on 01672906886. |
