Along with the news of the Canon EOS M5 this morning, Canon unveiled two new lenses. One for their DSLRs and the other for their mirrorless system.
The EF 70-300mm F/4-5.6 IS II USM is an improved version of the same lens sans II. The new version offers an improved image stabilization system. It also introduces a built-in monochrome LCD which can indicate focus-distance, focal-length or shake level along 2 axis. This could potentially help the user stabilize the lens while shooting in Live-View such that the LCD is visible while framing. Using the traditional OVF though, it remains to be seen how useful it is.
This telephoto zoom covers a full-frame imaging circle, so it is usable with any Canon DSLR. Construction of the lens has been improved but this remains a consumer-grade variable aperture zoom, so it is nor weatherproof by any means. This new lens is scheduled to ship in December for a retail price of $549 USD. Amazon, Best Buy, B&H Photo and Adorama are already accepting pre-orders.
The EF-M 18-150mm F/3.5-5.6 IS STM is the first high zoom-ratio lens for Canon EF-M mount. It offers an 8.3X optical zoom with built-in image stabilization. Its variable maximum aperture is quite dim as usual with such high zoom lenses. With a minimum focus distance of 25cm at wide-angle and 45cm at telephoto, it offers the highest magnification ratio of any EF-M mount at 0.31X.
To match the quietness of mirrorless cameras, this EF-M 18-150mm lens features a quiet STM stepping motor. This Micro USM-type motor allows fast and precise movements needed to focus smoothly during video. As other super-sonic motors usually do, this one supports full-type AF.
