Announced 07 February 2011:
Canon U.S.A., Inc., a leader in digital imaging, today announced two new versions of its popular Image Stabilizer (IS) super-telephoto lenses. The EF 600mm f/4L IS II USM and EF 500mm f/4L IS II USM super-telephoto lenses deliver incredible image quality at all apertures for professional photographers and filmmakers. It has been 11 years since Canon initially introduced its Image Stabilized 500mm and 600mm lenses and in that time the Company has listened to feedback from professionals and worked to implement their most desired enhancements. Replacing the current EF 500mm f/4L and EF 600mm f/4L IS lenses, both the new EF 600mm f/4L IS II USM and new EF 500mm f/4L IS II USM have experienced a drastic weight reduction making them lighter and more durable than their predecessors. Both lenses also achieve a higher level of image quality through the incorporation of two fluorite optical lens elements which help to minimize chromatic aberration and eliminate color blurring around the edges of the subject. Both new lenses offer improved Image Stabilization, providing the equivalent shutter speed of approximately four steps faster in addition to enhanced durability and operability through thoroughly re-designed optical and mechanical components.
“These lenses were made to be used under the harsh and challenging conditions faced by professionals in the fields of photojournalism, sports and nature photography. Utilizing valuable customer feedback, we have re-designed these lenses to create a powerful telephoto lens lineup for working professionals,” stated Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies and Communications Group, Canon U.S.A.
Lighter, More Durable and Enhanced
Canon engineers succeeded not only in reducing the overall weight of these lenses but improving on their optical performance as well. The optical formula of each new lens was re-designed to include two fluorite elements instead of one fluorite and two Ultra-low Dispersion (UD) glass elements. The new lens element configuration weighs less yet performs better. Other factors contributing to the overall weight reduction include increased use of magnesium alloy, use of titanium and a smaller and lighter Image Stabilizer mechanism.
Optically, both lenses will outperform their predecessors through the use of two fluorite elements over the previous one fluorite and two UD glass elements. More fluorite results in better image quality as it reduces chromatic aberration to a greater degree than UD glass. The reduction of chromatic aberration contributes to superior resolution, contrast, and color fidelity; this is especially evident when used in conjunction with Canon’s Type III EF Extenders. In addition to the fluorite lens elements, the new super-telephoto lenses also include a nine-blade circular diaphragm for a smoother appearance in areas outside the depth of field of the main subject. In addition, Canon’s SWC (Subwavelength Structure Coating) is applied to four internal groups in each lens to improve resistance to flare and ghosting.
A convenient and useful feature when shooting in the often adverse conditions professionals find themselves in, these new lenses are treated with Canon’s new fluorine anti-smear lens coating. The fluorine layer is highly oil- and water-repellent so that any oil smears or water droplets on the lens can be wiped off quickly and easily, without the aid of solvents, using a soft dry cloth.
The new Series II EF super-telephoto lenses can correct camera shake up to four full shutter speed steps, compared with two shutter speed steps with their predecessors. This improvement is made possible by a new low-friction stabilizer mechanism that is not only more efficient than the previous design but also smaller and lighter. Other enhancements to the IS systems of both new super-telephoto lenses have enabled quieter operation; ideal for use during video capture.
Canon has developed a third Image Stabilization mode option for its super-telephoto EF lenses. First introduced in late 2010 with the EF 400mm f/2.8L IS II USM, and EF 300mm f/2.8L IS II USM lenses, and now available on the new EF 500mm f/4L IS II USM and EF 600mm f/4L IS II USM lenses, IS mode 3 is designed to provide professional sports and wildlife photographers with greater tracking flexibility. When mode 3 is selected on the lens, the Image Stabilization effect will not occur until the shutter is pressed, making the viewfinder image more natural in appearance while tracking a subject. In mode 3 when the shutter button is pressed halfway, the lens will begin detecting camera or lens movement and only during exposure, when the shutter is fully depressed, will the Image Stabilization engage.
Helping filmmakers achieve smoother and more appealing focus shifts when filming on EOS DSLR cameras, Canon has included a new Power Focus (PF) mode on the Company’s new super telephoto lenses[i]. This mode allows manual rack focusing to be operated smoothly by turning a playback ring that is normally used for the focus preset function. Both low-speed and high-speed focus shifting are available.
Additionally, a new security slot attachment has been included on both of the new super-telephoto lenses to allow a wire-type security lock to be easily affixed, a great safety feature for professionals shooting from high vantage points above arenas and crowds.
Canon EF 600mm f/4L IS II USM Lens for Wildlife and Photojournalism
The Canon EF 600mm f/4L IS II USM is the successor to the current EF 600mm IS lens first introduced in 1999. This new lens has been engineered for outstanding optical performance and durability and includes two new fluorite lens elements for improved quality and reduced chromatic aberration. Helping photographers in the field, Canon has reduced the overall weight of the lens by a substantial 27 percent from 189.1 oz to 138.3 oz. The Image Stabilizer provides an equivalent of approximately four full shutter speed steps of shake compensation and has been enhanced through the incorporation of a rolling-ball-friction system in place of sliding parts in the compensation optics barrel for a minimum-friction structure. The overall durability of the lens has also been enhanced through increased usage of magnesium alloy and titanium for lens barrel components, together with weather sealing for all exterior joints and switches and a new fluorine anti-smear coating is applied to the front and rear elements.
The Canon EF 600mm f/4L IS II USM lens is expected to be available in June for an approximate retail price of just $11,999.00.
UPDATE: This was delayed care of the tsunami; as of June 2011, expect it in December 2011, still at $12,000. -

Protagonista di alcune indiscrezioni filtrate in rete nelle settimane scorse, il nuovo super zoom Tamron SP 150-600mm f/5-6.3 Di VC USD (model A011) è stato ufficialmente annunciato.
Rispetto alla precedente versione (model A08), il nuovo obiettivo, disponibile con attacco Canon, Nikon, o Sony, guadagna 50 mm sul medio tele e 100 mm sul tele spinto, pur mantenendo un design compatto in relazione alle focali che mette a disposizione del fotografo appassionato di fotografia naturalistica, o sportiva.
La costruzione - 20 elementi in 13 gruppi - comprende 3 elementi in vetro LD (Low Dispersion). I rivestimenti eBAND Coating e (Broad-Band Anti-Reflection) promettono la massima protezione contro i riflessi.
Il diaframma è circolare a 9 lamelle, per una sfocatura intenzionale dello sfondo ('bokeh') ottimale.
Lo stabilizzatore ottico VC (Vibration Compensation) incorporato riduce il rischio di mosso nelle immagini.
La minima distanza di messa a fuoco è di 2.7 metri. Il diametro filtri è di 95mm. Lo zoom misura 257.8 mm (lunghezza) x 105.6 mm (diametro). Il peso è di 1951 grammi.
L'obiettivo dispone di un motre AF USD (Ultrasonic Silent Drive), veloce e silenzioso.
La messa a fuoco manuale full-time permette micro aggiustamenti del fuoco anche quando l'autofocus è attivo.
Gli accessori inclusi nella confezione: paraluce, attacco per il treppiede rimovibile ridisegnato, per una maggiore stabilità. Incluso anche il software SILKYPIX Developer Studio for Tamron per il formato RAW.
Montato su una macchina fotografica APS-C lo zoom Tamron SP 150-600mm f/5-6.3 Di VC USD equivale a un 233 - 930 mm.
Per il momento Tamron non ha comunicato né il prezzo né la data di uscita del SP 150-600mm f/5-6.3 Di VC USD. -

Sigma 50-500mm f/4-6.3 EX DG HSM Lens
Any 10x SLR zoom lens (50mm x10 = 500mm) is going to be attractive, but one that ends with a 500mm focal length is going to get an especially high amount of attention.
Sigma 50-500mm f/4-6.3 EX DG HSM Lens, for this reason, but not for this reason alone, is a very popular lens.
The fact that Canon's longest zoom ends at 400mm and costs much more increases the demand for this lens.
I should point out right up front: Though designated 500mm, this focal length seems overstated - 450-470mm or so feels about right. Still not a bad long focal length on a zoom with this overall focal length range.
As can be expected for a lens with a 450-500mm focal length available, the Sigma 50-500mm f/4-6.3 EX DG HSM Lens is not small or light.
It has even acquired a nickname - "Bigma".
The 50-500 measures 3.7" x 8.6" (95mm x 218.5mm) and weighs 4.1 lb (1.8 kg).
You can carry this lens all day - but you will know that you did.
It is not too heavy to handhold, but a support will be welcomed if you intend to have it in shooting position for long periods of time.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens' build quality is on par for Sigma's EX line - very good.
The focus and zoom rings are nicely sized, nicely shaped, smooth and well-damped.
The switches are raised and not as integrated as they could be, but this is a relatively minor issue. The lens finish is Sigma's standard black matte EX finish.
I think it shows marks too easily - others really like it. As do all super-zoom lenses, the 50-500 extends significantly at its longest focal length range as can be seen in the comparison pictures below.
I mentioned the switches - there are two.
The first is very straightforward - AF or MF. The other has two functions.
The first is a zoom lock to prevent gravity-induced zoom creep - and this lens will rapidly extend if pointed downward.
The other function is used to restrict the focal length to 100mm or longer.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens is compatible with the Sigma 1.4x and 2.0x Extenders - but only at focal lengths of at least 100mm.
Thus, the lock switch's second function. Most Canon camera bodies will not AF with extenders mounted behind this lens.
AF is accomplished via Sigma's HSM (Hypersonic Motor).
It is quiet, does not extend (rear-focusing), fast and has proven accurate to me even in AI Servo mode shooting sports.
The only downside I've noticed is that the Sigma 50-500mm f/4-6.3 EX DG HSM Lens does a lot of focus hunting when shooting sports - a focus distance limiter (not provided) would be a big help. FTM (Full Time Manual) focusing (I really like this feature) is available and the front element does not rotate.
Colors appear accurate, but contrast is not as good as some of the other options - none of which have this focal length range of course.
Vignetting is well controlled through the middle focal length ranges, but will be noticeable at 50mm and from 300-500mm with a wide open aperture.
Users with 1.6x bodies will probably only notice vignetting between 400 and 500mm.
Full frame users will notice some vignetting on the long end even when stopped down to f/8. CA (Chromatic Aberration) is well controlled with some showing in corners at 50mm and from 400-500mm.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens shows a little barrel distortion at 50mm and moderate pincushion distortion over most of the rest of the focal length range. Distortion is less noticeable at longer distances (not unusual).
Flare is well controlled on the wide end, but increases to very strong with the sun touching the corner of the frame at the longer focal lengths. Stopping down helps - I haven't had flare issues when actually using this lens.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens is decently sharp wide open in the center at 50mm through 200mm but degrades rapidly to soft at 300mm and beyond.
Corners are not as sharp as centers (not unusual), but are not bad wide open until the longer focal lengths. 200mm seems to be a sweet spot for this lens. Stopping down 1 and especially 2 stops makes a big difference in the results.
However, stopping down an already slow lens with no image stabilization means you need a lot of light or high ISO settings to stop subject motion. To handhold this lens at the longer focal lengths, you need a lot of light, high ISO settings or a support such as a tripod - and a relatively still subject.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens' 9-blade aperture gets narrow fast - going from f/4 @ 50mm to f/4.5 at 57mm to f/5.0 at 72mm to f/5.6 at 116mm to f/6.3 at 417mm.
A big lens that takes a big filter. The Sigma 50-500mm f/4-6.3 EX DG HSM Lens sports uncommon 86mm filter threads - quality filters of this size are expensive and not shared by many lenses.
The 50-500 comes in a nice padded Sigma lens case and includes a shoulder strap that attaches to the also-included removable tripod ring.
Getting the lens cap off when the included petal'd lens hood is installed is very difficult.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens is available in Canon (reviewed), Nikon (D), Sigma, Pentax, Sony and Four Thirds mounts.
My obligatory standard disclaimer: You should know that there are potential issues with third party lenses.
Since Sigma reverse engineers (vs. licenses) manufacturer AF routines, there is always the possibility that a new body might not support an older third party lens.
There are examples of this happening in the past. Sometimes a lens can be rechipped to be made compatible, sometimes not.
Second, there is the risk of a problem that results in the lens and body manufacturers pointing blame at each other. However, Sigma USA's 4-year warranty is far superior to Canon's standard 1 year warranty (though many credit cards will double the Canon warranty for you).
A focal length this wide and long covers a huge range photo opportunities - Only the wide end is missing. Wildlife, always needing all the focal length you have, is one of the most common subjects for the Sigma 50-500mm f/4-6.3 EX DG HSM Lens.
Another popular Sigma 50-500 target is sporting events - bright daylight games are best-suited for this lens.
This is a nice focal length range for air shows. People, places, things ... there's just sooo much that fits between 50 and 500mm.
Before purchasing this lens, you should also consider the Canon EF 100-400mm f/4.5-5.6 L IS USM Lens and Sigma 80-400mm f/4.5-5.6 EX DG OS Lens.
The Canon has better image quality (especially sharpness and contrast) and has image stabilization, but costs more and has a shorter focal length range.
I liked the Sigma 80-400's image quality better than the 50-500 and it has optical stabilization, but it weighs more, does not AF as well and has a shorter focal length range.
The Sigma 50-500mm f/4-6.3 EX DG HSM Lens is not cheap, but it is a decent value. And nothing else gives you 50-500mm in one lens.
When a situation presents itself, you may not have time to change lenses. Even a mediocre shot is better than a missed shot. -
