The image sensors of digital SLR cameras continue to offer higher and higher resolution, and photographers are looking for high-performance lenses that leverage these sensors’ full power. In the case of zoom lenses as well, which are a dependable go-to in a wide variety of photographic conditions, photographers want convenience combined with exceptional optical performance. The new SIGMA 24-105mm F4 DG OS HSM zoom lens more than fulfills these requirements, offering exceptionally stable high resolution from wide-angle to medium telephoto photography.

While featuring a large-aperture 82mm filter size, this lens minimizes optical aberrations and avoids reduced peripheral brightness, an issue that tends to affect lenses with similar specifications. Each lens is checked with Sigma’s proprietary A1 MTF (modulation transfer function) measuring system to ensure it offers exceptional quality for the high-megapixel era. Try this new high-performance zoom for yourself, and experience Sigma’s uncompromising pursuit of high resolution.

The full realization of the Art product concept for you to hold in your own hands and appreciate with your own eyes.

Review – Canon EF 17-40mm f/4L

Review – Canon EF 17-40mm f/4L

New Review
Justin has completed his review of the Canon EF 17-40mm f/4L ultra wide angle zoom lens from Canon. For a lot of people, this is their first wide angle zoom and becomes a workhorse.

I know one landscape/nature photographer who uses this lens extensively and it’s used for about 75% of images that he sells, and he sells a lot! This is a great lens for publishing and using all the time. I have a hard time recommending the 16-35 f/2.8L II to anyone other than an event photographer. The EF 17-40mm f/4L is a workhorse that is reliable and doesn’t cost a whole heck of a lot.

Justin likes it a bit less than I do, but the review is pretty positive.

More talk of the biggest of the whites
We’re told that an announcement for a new EF 800 f/5.6L IS II could come at any time, as the update is “ready to go”.

We’ll see if Canon can price it higher than Nikon’s version!

More Medium Format Talk [CR1]

More Medium Format Talk [CR1]

This and that
A few people have written in to confirm that Canon is exploring the possibilities of entering into the medium format segment.

We’re told nothing is imminent, but things could change quickly in the next few months. How long this has been going on is unknown, but it does sound like it’s a real possibility.

No one has confirmed or denied that Phase One is the medium format company in question.

Over at NL, they received an outright dismissal to the concept. However, a second source said Canon is going to be all in, and will announce in a big way some time in 2014.

Canon Testing a 75+ Megapixel EOS-1 Body? [CR1]

Canon Testing a 75+ Megapixel EOS-1 Body? [CR1]

The big megapixel camera gets bigger!
Photography Bay is reporting that a good source of theirs has told them that Canon is actively testing a 75+MP EOS-1 DSLR camera body.

I don’t find anything surprising in the megapixel count, as Canon has announced enormous megapixel sensors in the past. However, this is the first I’ve heard of an actual product using image sensors with this much resolution.

Previous rumors have placed the “big megapixel” camera from Canon in the 40-50mp range.

We do expect such a camera to make its way to us sometime in 2014.

EOS 5D Mark III w/24-70 f/4L IS Kit Coming Soon

EOS 5D Mark III w/24-70 f/4L IS Kit Coming Soon

Is the EF 24-105 f/4L IS Going Away?
The EF 24-70 f/4L IS will soon be kitted with the EOS 5D Mark III. I’m also hoping we’ll see it with the EOS 6D as well.

The release date for the new kit(s) is June 13, 2013.

As of writing this, we have no pricing. Expect to see some “white box” discounts on the EF 24-70 f/4L IS soon.

I haven’t heard anything in regards to the EF 24-105 f/4L IS getting discontinued, so I’d expect to see that lens in kits for some time to come.

EF 24-70 f/4L IS $1199

Announcement: Canon EF 200-400 f/4L IS 1.4x

Announcement: Canon EF 200-400 f/4L IS 1.4x

London, UK, 14 May 2013 – Canon today adds a new category to its range of high-performance super-telephoto lenses, with the introduction of the EF 200-400mm f/4L IS USM Extender 1.4x to Canon’s acclaimed L-series. The EF 200-400mm f/4L IS USM Extender 1.4x features a flexible 200-400mm focal range with a fixed f/4 aperture, 4-stop optical Image Stabilizer and for the first time in a commercially available lens, a built-in 1.4x extender. These features combine to provide an outstandingly versatile lens for professional sports or wildlife photographers. A robust magnesium alloy design, environmental protection and specialised lens coatings also make it ideal for mobile use, combining with the finest quality optics to deliver exceptional results, even in the harshest conditions.

Get closer to the action with superior image quality
The reach of the EF 200-400mm f/4L IS USM Extender 1.4x is boosted by its internal 1.4x extender, which is engaged or disengaged at the flick of a lever to provide an extended focal length of 280mm to 560mm – allowing photographers to get even closer to distant action. Ensuring the highest image performance, the optical design includes both fluorite and Ultra-low Dispersion (UD) lens elements, which help minimise chromatic aberration and eliminate colour blurring. Advanced anti-reflection SubWavelength Structure Coating (SWC) and Super Spectra Coating also reduce ghosting and flare. Thanks to the use of the latest optical technologies, image performance is unaffected when the integrated extender is used.

With a constant f/4 aperture the use of high shutter speeds to capture fast-paced action or a low-light scene is possible. A newly designed optical Image Stabilizer, which provides users with a four stop advantage, while IS ‘Mode 3’ applies image stabilisation only at the time of exposure – ensuring that photographers can pan with fast-paced action without IS overcompensating for movement. This feature is ideal for sports photographers, who typically have only a split-second to capture a subject in front of them.

Powerful, flexible focusing
The EF 200-400mm f/4L IS USM Extender 1.4x features Canon’s pioneering ring-type Ultrasonic Motor providing fast, silent autofocusing. For those who prefer to fine-tune focus themselves, full-time manual override allows photographers to manually focus at any moment when using AF. The Power Focus (PF) mode also increases versatility during movie shooting with the EOS-1D C or EOS-1D X, enabling photographers to achieve an accurate pull-focus effect at one of two speeds, simply by twisting the focus recall ring and stopping at a pre-set distance.

High-performance design for professional demands
Designed to answer professional demands for superior image quality and versatile zoom range, the EF 200-400mm f/4L IS USM Extender 1.4x a boasts a premium-quality design befitting Canon’s industry-renowned L-series lenses.

The tough magnesium alloy chassis ensures that, despite the inclusion of the 1.4x extender, the lens is a similar weight to lenses of comparable focal length. Fluorine coatings on the front and rear lens elements also reduce the ability of dirt to cling to the lens surface, while a dust and water-resistant construction allows photographers to shoot in challenging weather conditions. The combination of outstanding optical performance, versatility, weight and tough construction will make it an essential part of any professional sports or wildlife photographer’s kitbag.

EF 200-400mm f/4L IS USM Extender 1.4x key features

  • Built-in 1.4x extender, for extra magnification when you need it

Review – Canon Speedlite 600EX-RT

Review – Canon Speedlite 600EX-RT

Our review of the Canon Speedlite 600EX-RT
Justin has completed his review of the Canon Speedlite 600EX-RT, and it’s a pretty thorough look at Canon’s latest flagship Speedlite.

The review is quite positive and seems to say that moving from a 430 or a 580 may be worthwhile, especially if you want to get more serious about your flash photography.

Justin’s comments
“Have a Canon camera? Need more light? Buy this flash. Flash photography may not be easy to master, but luckily for you, there are so many incredible resources on the internet to help you learn how to use and modify your flash to get the look you’re trying to achieve. All I ever asked for was a flash that actually responded to my needs, making me feel comfortable and confident on a shoot; just like the 600EX-RT does.”
