Canon EF 75-300mm f/4~5.6 (USM) MK II Telephoto Zoom Lens Marketed: 1995, Discontinued: 1999 Along with a few other well-spec "budget" wideangle zoom that were sold very well in numbers, Canon also saw the commercial potential of this Tele-zoom and updated the lens in both standard MM and USM versions in 1995. Generally, the market during this time was the beginning of a long prime period of Canon with its clear dominance at the professional user's market with the hugely successful Canon EOS-1N series. Overall, the Canon EOS system has matured both in cameras as well as in the EL lens lineup. The update was essentially part of a broad scale lens updating program during the mid of '90.

In fact, other than a golden-line USM ringed around mid section to seperate the two, BOTH the lenses shared a common update. During its launched, some equipment reviewers did asked about the EF 75-300mm f/4-5.6II USM in a Q & A session: Q: Compared to the EF 75-300mm f/4-5.6 USM, what improvements have been made to the EF 75-300mm f/4-5.611 USM? Canon spokesman oulined as:. - The exterior sports a silky finish to give a high-quality look. The zoom-ring ring rubber covering is finer, making it easier to grip and giving the lens a high quality look. Other design-related details have been improved. The internal mechanical construction and electrical circuits have been improved. However, optically both lenses remained unchanged, retaining the optical formula as 13 elements in 9 groups formation.

The debut of these two lenses timed themselves at a time which we witnessed some brilliance of Canon EF lenses being introduced at almost the same time (such as the Canon EF 70-200mm f/2.8L USM) but the lens that caught the entire community in 1995 was caught by introduction of the first zoom lens that incorporated with an innovative Image staberlizer technology. Rather surprisingly, Canon has chosen its immesensly popular 75-300mm as its first trial. The resulting product, Canon EF 75-300mm f/4~5.6 II IS USM as it was called, stole the limelight and thus, there are actually three versions of the Canon EF 75-300 tele-zoom lens in the EF lens family at this period.

Although not as beutifully done as with the Canon luxulous, professional oriented L-series family, the overall built quality of the two lenses is above average. The rear metal lens mount is a rare treat found among all the entry level budget zoom lenses flooding in the market today. Credit: Image courtesy of Creation House @EBAY®, Image(s) copyright © 2005.

The Product Concept is basically improved the Canon products with a strategically priced tele-zoom as other rivaling manufacturing Companies which includes the third party labels also realized its popularity. The key to add value is via improved high-quality external appearance based on a new design which includes a smoother, silky surface finish as well as a new pattern zoom ring. The performance comparison between the identical lenses between EF 75-300mm f/4-5.611 USM and EF 75-300mm f/4-5.6 II shares a common optical design but the latter uses a DC motor to drive the autofocus. Since it uses a rubber belt to suppress the noise level, the AF noise is only slightly higher than the EF 75-300mm f/4-5.6 II USM's. The DC motor alternative was retained in the EF lens family was aimed to make the lens more affordable to more people (or fencing off threats from third party label lenses).
