There are certain pretty true reports around that Canon UK is letting the release of a new 70-200 mm f/2.8L IS II slide to the public. It seams that this will be available somewhere in September. Maybe this will have the new Hybrid Image Stabilizer, that Canon is bragging about.
Canon UK is having a show on October 27th and 28th to show all the new stuff.

Recently I read a press release in which Canon announced an improved and newly-developed image stabilization technology called Hybrid Image Stabilizer. Canon company claims the technology is the world’s first to compensate for both angle and shift movement during the exposure, resulting improved stability in macro photography in particular.
And here’s the press release:
LAKE SUCCESS, N.Y., July 22, 2009 – Canon U.S.A., Inc., a leader in digital imaging, announced today the development of Hybrid Image Stabilizer (IS), the world’s first* optical image stabilization technology that compensates for both angle camera shake and shift camera shake. The technology will be featured in interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of 2009.
Several different preventative methods and corrective procedures have been introduced to compensate for errors caused by camera shake, which occurs when a camera moves while its shutter is open and its image sensor is exposed to light.
Canon began researching methods to compensate for camera shake in the 1980s, and in 1995 launched the EF 75-300mm f/4-5.6 IS USM, the world’s first interchangeable SLR camera lens to feature a mechanism that compensates for optical camera shake. Since then, the company has continued to produce a variety of interchangeable lenses with image stabilization capabilities, and boasts a total of 21 such lenses in its current product lineup.
Canon’s newly developed Hybrid IS technology optimally compensates for angle and shift camera shake. Sudden changes in camera angle can significantly affect images taken during standard shooting, whereas shift-based shaking, which occurs when a camera moves parallel to the imaging scene, is more pronounced in macro photography and other close-range shooting.
The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angle-based shaking and is found in all previous Canon optical image stabilizer mechanisms, as well as a new acceleration sensor that determines the amount of shift-based camera shake. Hybrid IS also employs a newly developed algorithm that synthesizes information from the two sensors to make optimal adjustments, thereby dramatically enhancing the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.
Canon is actively engaged in ongoing research and development of interchangeable SLR camera lenses incorporating Hybrid IS technology, and is aiming for the early commercialization and inclusion of the lenses in a wide range of products.

Hi, guys. I haven’t wrote anything for more than a month, and I apologize for that. I had some personal things to take care of. Now hopefully I will continue writing new posts.
I would like to let you know that Canon has just announced a line of some amazing new lenses with optics that intensify the light as it passes through. This technology has been in development for many years, and because of a new revolutionary manufacturing process, the production of this high quality optics it possible at affordable prices.
Canon can’t release details of exactly how they make the lenses (for obvious reasons) but, they have said that the process of manufacturing has to take place in complete darkness until the new Starlight Spectra Coating, which is the key to the intensifying of light, has time to develop its light gathering ability.
So Canon has started the line of new lenses with this 20-400mm f/2.8 IO (Intensifying Optics) IS USM, and from what I understand they will release more lenses with this special ability.
As a side note, I have read somewhere, forgot where, a rumor that Canon stops producing the famous 70-200mm f/2.8. Now i can understand why, maybe because they are going to release a new version of 70-200mm with IO.
So the estimated price is somewhere around 4100$ (3100€) and the release date it’s sometime in autumn 2009. Also here’s a list of key features:
Aspherical optics used on all elements except for front SSC coated element
Pro quality optics on a par with L series lens quality
Robust design with build quality equivalent to L series lenses
Image intensifying optics used in front element of lens
Lens feature full time mechanical manual focusing
Fully flocked throughout to prevent internal reflections
One touch design for speed of zooming
Optical image stabiliser with 6 stop correction for handshake

There will be a couple of announcements to be made by 25th of March by Canon. It seams that a new improved lens will be one of them. I don’t what exactly will be improved, but I am guessing a new Ultra Sonic Motor to facilitate a better and faster focusing, and I am guessing that it will be sharper than the previous model.
Also there is a new rumor that on the same day the new Canon TSi/500D will see the daylight. Although the first rumor said that this is going to be released at the PMA ( check this ), but it wasn’t released then. Anyway, we will wait an see.
Ohh and here is a list of specs for those of you who didn’t read the first post about this Canon TSi/500D:

A couple of days ago, at PMA show, Sigma presented 2 entry level lenses both with OS (optical stabilization) and one ultra-wide lens.
Sigma 10-20mm f/3.5 EX DC HSM
It seams that Sigma improved the popular ultra-wide lens 10-20mm f/4-5.6 EX DC HSM made for APS-C/DX sensors (Non Full Frame), making the new version with fixed a aperture of f/3.5 through the focal range. It also has two Super-Low Dispersion and two Extraordinary-Low Dispersion glass elements for the correction of chromatic aberrations. It will be available with mounts for Canon, Nikon, Sigma, Sony and Pentax DSLRs. Hopefully this will at leas as good as it predecessor, we will see some future reviews, I would like an ultra wide lens for my cropped sensor 40D.
Sigma 18-50mm f/2.8-4.5 DC OS HSM
Sigma also has released a standard zoom lens featuring an optical stabilizer and a wide aperture at it’s shortest focal length. This is also having twoSuper-Low Dispersion glass elements for the correction of chromatic aberrations. As the previous lens it has a Hyper Sonic Motor (HSM) for fast and silent focusing. Sigma also states that its OS it would work on Sony and Pentax bodies with in-body stabilization systems. This also will be available with mounts for Canon, Nikon, Sigma, Sony and Pentax DSLRs. Bottom line this is a good lens to replace the kit lenses, because this is faster.
Sigma 50-200mm f/4-5.6 DC OS HSM
Sigma also talked about it’s telephoto zoom lens. This lens has the same image stabilization as the 18-50mm f/2.8-4.5 and also has the Hyper Sonic Motor. Something to note, due to fact that is a low-budget lens, is the fact that it has internal focusing with a non-rotating front element. Also the lens is treated for correction of chromatic aberrations.

We often find ourselves wishing and talking about DSLR cameras, we compare them and adopt a geek language babbling about shutter speeds, ISO, camera features, image processing and other technicalities. This makes us forget about the most important piece of gear that helps us take the photograph we want, and that is the LENS.
The lens is the eye of the camera, and every photograph is recorded after the light come through the lens. Taking your DSLR without putting your lens on, and start taking photos, your see that the image processor records and extremely blurry photographs.
Lenses allows us to:
get more light ( lenses with big aperture), even if your camera have high iso numbers, you’ll still need a fast lens to get fast shutter speeds.
get close-up of your subject without actually being close ( telephoto lenses )
get incredibly sharp photographs
get sharp images of a mosquito’s eye ( macro lenses )
isolate our subject with small depth of field
capture sharp images of huge mountains and big fields of flowers ( wide lenses )
make creative photographs with lens-baby
As you can see lenses are way more important that the camera.
In creating the ultimate lens is involved a lot of precision mechanics and optics science. Also there is use a high amount of very expensive glass materials, so you will need a lot of glass elements in building a zoom lens with fast aperture. Also every piece of glass is treated with other substances for durability, minimize chromatic aberrations, reduce flare, etc. Also raw optical glass costs around 1000$ per kilogram, as Discovery Channel points out in their “How it’s made” show.
All of this being said, you can easily explain why a good lens costs hundreds and even thousand of dollars.
Also please check this video created by Discovery Channel on how lenses are made.
Taking sharp photographs is the dream of every photographer. However taking crisp, clean images can be quite challenging. I would like to share with you guys some tips on how to get razor sharp photographs, but before that let’s see what are the common causes for lack of sharpness:
Wrong focusing. The most common cause for blurry photos is not focusing right. Often happens to focus on the wrong part of the image, or using a very narrow depth of field, or taking the photo quick without checking if it is in focus, and all of this helps in throwing your subject out of focus and obtaining blurry photographs.
Low value of the shutter speed. This causes 2 sets pf problems: Camera shake and Subject movement. This two makes blurry photos because your shutter speed is too low to freeze the action.
Noise. Sometimes using high ISO values might get you results with lack of sharpness. Although since cameras evolve so quickly these days, higher ISO values might still get you very sharp images.
Here are 9 ways of improving your photographs sharpness:
Surfing the web I have came across a very neat gadget. It’s a lens accessory that has a cut-out on the side and a precision mirror inside. This enables you to shoot left, right, up, or down (it swivels 360 degrees), all looking like there were shot straight ahead. The concept? Point your camera 90 degrees away from your subject – and the mirror inside the attachment reflects the image to your lens.
This is an excellent accessory for shooting shy people, afraid of being photographed, or for street photography without being noticed.
It’s called (very funny) “Super-Secret-Spy lens” and it’s sold by Photojojo.com.
Specifications:
Works with any SLR lens: Canon, Nikon, Sony, Pentax, Olympus, etc.
You need lenses with diameter of: 37mm,46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, and 77mm. It has an adapter for each size.
Works with zoom lenses (at least 50mm). If you use wider lens you will encounter heavy vignetting
Swivels 360 degrees to let you take 90° candid shots in any direction
You can use AF an any other lens or camera functions without being limited.
