Olympus has added to their Micro Four Thirds family of lenses the M.ZUIKO DIGITAL 17mm f1.8 lens (34mm in 35mm equivalent).
This high quality, compact lens features a metal body and a Snapshot Focus mechanism for pan focusing with a distance indicator.
The M.ZUIKO DIGITAL 17mm f1.8 has an advanced optical system featuring three aspherical lenses, including a Dual Super Aspherical element to correct aberrations, as well as a High Refractive index lens to correct high spherical aberrations. Olympus’ exclusive ZERO (ZUIKO Extra-low Reflection Optical Coating) lens coatings are applied to the elements to reduce lens flare and ghost images even when shooting against the light.
The Snapshot Focus mechanism lets users easily take blur-free images by shifting the focusing point to a specific distance. Sliding the focus ring back reveals range markings on the lens barrel, including distance and depth of field scales, which can be used as guides as the user adjusts the focal distance by rotating the ring.
With a total length of just 1.4 inches, the M.ZUIKO DIGITAL 17mm f1.8 is incredibly compact. The lens also employs Olympus’ proven MSC (Movie & Still Compatible) autofocusing mechanism for fast and quiet focusing.
The Olympus M.ZUIKO DIGITAL ED 17mm f1.8 Lens will be available in December for $499.99

Canon has announced a new Rebel, the EOS Rebel T4i (650D). The new Canon Rebel T4i features a new touchscreen lcd, uses an 18-megapixel CMOS (APS-C) sensor, a DIGIC 5 Image Processor and can shoot up to five frames per second.
The T4i also features an extended ISO range of 100–12800 and a new AF system. It uses what Canon calls a “new Hybrid CMOS AF” system, designed to achieve faster focus when shooting stills or video in Live View mode.
Also new to the Rebel line is the T4i’s new 3-inch Vari-angle, Touch Screen Clear View LCD monitor II with “fingertip” controls, touch-menu and touch still and video capabilities. The flip-out, side-swiveling vari-angle screen has 1.04 million dots resolution to create clear and crisp image and video playback and Live View.
Canon says the T4i’s predecessor, the Canon Rebel T3i from 2011, will remain in the line but the older T2i will be discontinued.
Canon also announced two new STM lenses for the Rebel T2i. The lenses, the EF-S 18-135mm f/3.5-5.6 IS STM zoom and the EF 40mm f/2.8 STM “pancake-style” prime lens, both use Canon’s new Stepping Motor technology, allowing the lenses to focus more smoothly and quietly.
When used in combination with the Rebel T4i Movie Servo AF feature, the two new Canon STM lenses can achieve continuous autofocus while recording video.
The Canon Rebel T4i, which goes on sale at the end of June 2012, will be priced at $849, (body only) and $949.99 as a kit when bundled with the non-STM version of the EF-S 18-55mm f/3.5-5.6 IS II lens kit. Canon will also sell a “Movie Kit bundle” of the Rebel T4i with the new EF-S 18-135mm f/3.5-5.6 IS STM lens for $1199.00.
The new EF 40mm f/2.8 STM lens and the new EF-S 18-135mm f/3.5-5.6 IS STM will also be sold separately at the end of June. The 40mm f/2.8 pancake STM lens will go for $199.99 and 18-135mm f/3.5-5.6 IS STM will sell for $549.99.
