At PMA 2004 Canon announced a new lens, the EF 28-300/3.5-5.6L IS USM. It's
very similar to the current EF35-350/3.5-5.6L in size and shape and is its
logical successor. Going from 35mm to 28mm at the wide end is well worth the loss
of the 300mm - 350mm range for most users, especially those using small sensor
DSLRs like the 10D or 300D where wideangle ability is compromised by the 1.6 crop
factor. On a 10D this lens would give the same angle of view as a 45-480mm zoom
(the 35-350 equates to a 56-560). Canon have also added their IS (Image
Stabilization) technology to the lens with improved IS performance. The first
generation of IS allowed hand held shutter speeds 2 stops slower than without IS.
Canon now claim a 3 stop advantage. The IS on this lens is dual mode, meaning
seperate setting for static use (including use on a tripod) and for panning. The
only real downside of the new lens is the price, Estimated selling price is
$2500. The current selling price for the EF35-350/3/6-5.6L is around $1400. I
haven't seen any comments from Canon on whether the EF35-350/3.5-5.6L will
continue in production, but given the difference in price and range they may well
keep around for a while.
The following information is from the Canon Press Release:
EF 28-300mm f/3.5-5.6L IS USM
The new EF 28-300mm f/3.5-5.6L IS USM is an entirely new L-series design lens
(and a significantly enhanced successor to Canon's EF35-350mm f/3.5-5.6L USM zoom
introduced 11 years ago). Though it offers 11x zoom capabilities (compared with
the 10x capability of its predecessor), this newly designed, 22-element L-series
lens combines Canon's newest optical glass advances, faster autofocus and a
groundbreaking Image Stabilization system that makes capturing incredible images
a snap, even when the zoom is at max, the shutter speed is slow and the camera is
The EF 28-300mm f/3.5-5.6L IS USM lens that features three ultra low
dispersion (UD) glass elements that reduce chromatic aberration, and three
Aspherical elements that reduce linear distortion and correct spherical
aberration during zooming (keeping image resolution and contrast high), together
with superior lens coatings that minimize reflection, especially when used with
digital SLRs. The shorter minimum focal length of the new lens versus the
previous 35-350mm model also makes the EF 28-300mm L zoom more suitable for
digital SLRs with image sensors smaller than 35mm format.
Among this lens' most significant enhancements is its highly refined Image
Stabilization (IS) system with new shake-detecting gyro sensors. IS is now
effective for correction of up to three shutter speed steps for handheld
photography, 50% better than the original EF75-300mm IS lens. Additionally, IS
remains effective with the new EF 28-300mm L lens even when it used on a tripod,
improving image quality by helping to eliminate the effects of reflex mirror
vibration at slow shutter speeds that are typically required in low light. The
lens features an IS mode switch that allows the user to select Mode 1 for general
stabilization or Mode 2 for deliberate panning. IS is activated within 0.5
seconds of depressing the shutter halfway.
Additionally, the EF 28-300mm f/3.5-5.6L IS USM lens features a new, faster
autofocus drive thanks to a new AF CPU and revised in-lens software (that
accelerates the transmission of data between lens and camera), a powerful, quick
and silent ring-type Ultrasonic Motor and an inner focus system that moves only
the lens' lighter elements during AF while keeping the front elements
Because of its extended zoom range, the new EF 28-300mm f/3.5-5.6L IS USM lens
features push-pull zooming operation (unlike most other EF lenses that utilize a
ring-type zoom) though it does have a zoom adjustment ring that allows a user to
loosen, tighten or lock the zoom control. The lens also permits closer minimum
focus than previously available — from 2.3 feet at all focal lengths
— and is capable of filling the frame with a subject as small as 3.2 x 4.8
inches at the 300mm zoom setting.
The lens is compatible with optional EF12/EF12II Extension Tubes at all focal
lengths and EF25/EF25II at mid-range and telephoto zoom settings. The EF25
provides a maximum magnification of 0.5x, effectively filling the frame with a
subject approximately 2 x 3 inches at the 300mm zoom setting. It is also
compatible with the 77mm 500D and 500 Close-up lenses for a maximum magnification
The EF 28-300mm f/3.5-5.6L IS USM lens kit includes a newly designed bayonet
mount lens hood, a detachable tripod collar and a soft lens case.
