As you probably noticed, I am somewhat biased concerning Canon gear when it comes to photography. Canon DSLR's, Canon point and shoots, Canon lenses and everything Canon including knock off Canon lens coffee mugs fill my ChadSorianoPhotoBlog. This obsession does not make me blind to other brands especially when it comes to budget alternatives to Canon products. So, I picked up from my friends at North Tampa Photography the SIGMA 24-70mm f/2.8 IF EX DG HSM standard zoom lens which has a street price of $899 for a practical lens review.
Just like my previous SIGMA 30mm f/1.4 EX DC HSM Practical Review, I wanted to give this SIGMA 24-70mm f/2.8 IF EX DG HSM standard zoom lens real time use out in the field for my practical review. "Real time" meaning capturing life's moments of my family one picture at a time. Nothing fancy or scientific but actual pictures to look at and inspect for yourself.
Why would you even consider the SIGMA brand with Canon? Value and limited selection. Considered Canon's workhorse, the EF 24-70mm f/2.8L USM standard zoom lens is no doubt the ultimate in color, sharpness and focus speed. Unfortunately, it has a street price of $1400 and definitely not for the budget conscious. The closest focal and aperture equivalent to this "L" lens with compatibility for full frame and crop sensor cameras is the SIGMA 24-70mm f/2.8 IF EX DG HSM lens. "L" stature for $1400 or SIGMA "stigma" for $500 less? Read on.
The SIGMA 24-70mm f/2.8 IF EX DG HSM verdict? The SIGMA is quite impressive. The standard zoom lens has the color, sharpness and dreamy bokeh of an "L" lens at all focal lengths. It definitely has that "pop". The SIGMA is not heavy and it is compact for such a fast lens even with the included hood attached. Vignetting at the widest focal length is barely noticeable on the 5D Mark II and can be tweaked in post. Overall, lens quality is just about equal to "L" stature.
Just like in my previous SIGMA 30mm f/1.4 EX DC HSM Practical Review, the SIGMA auto focus is slow and inaccurate in low light situations when compared to the Canon brand. My "OOF" shots declined in number only in very bright situations. The SIGMA AF is definitely not Canon "L" quality especially in low light. It is ironic that a fast aperture lens tailored for low light shooting has inconsistent AF in dark situations. Definitely, a "stigma" in my opinion.
This AF "stigma" is not a problem for landscape photography. If portraits are not your staple, the SIGMA 24-70mm f/2.8 IF EX DG HSM standard zoom lens is perfectly fine. The SIGMA at 24mm is nice and clean for wide shots. Even in low light landscape situations such as "twilight" shots can be manually focused for critical focus. You can use the $500 savings for a nice inexpensive prime such as the Canon EF 35mm f/2 or the EF 50mm f/1.4 USM for portraits.
If you are looking for the ultimate "walk around" lens for your 5D Mark II that does just about everything flawlessly, save your coin for the Canon EF 24-70mm f/2.8L USM lens. If landscapes or still life are your fancy, the SIGMA 24-70mm f/2.8 IF EX DG HSM is just fine and you save $500 as well.
The stigma of SIGMA wanes with every photograph through this amazing prime lens dedicated to APS-C crop sensors. The SIGMA 30mm f/1.4 EX DC HSM lens satisfies the "fast aperture" and standard focal length crowd for APS-C DSLR's. As for the "stigma", SIGMA manufactures SLR camera lenses under the name of "Quantaray" which is sold by Ritz and Wolf Camera stores. I am not a big fan of Ritz Camera or the budget priced "Quantaray" in house brand they retail. With much doubt and skepticism, I picked up my SIGMA 30mm f/1.4 EX DC HSM from my friends at North Tampa Photography for a street price under $500 for a practical lens review.
"Practical" means real time use out in the world. My world consists of capturing the true to life moments of my family of five, which includes a 3 month old newborn. No complicated wavelength and focus charts here. I go out and shoot pictures. Lots of pictures and even video to be exact.
Paired with my compact Canon EOS Rebel T3i/600D, the SIGMA 30mm f/1.4 EX DC HSM has definitely the "L" pop in color, sharpness and contrast. The EX designation denotes a sturdy build, while the DC means digital crop. The HSM is an acronym for Hyper Sonic Motor for auto focus. The lens body feels sturdy and chunky but not heavy. Mated to the T3i/600D, this lightweight combination provides a "Rangefinder" camera like feel such as the new Fuji X100 or even the ultra expensive Leica M9.
The SIGMA 30mm f/1.4 EX DC HSM is categorized as a wide angle prime lens. On a crop camera, 30mm focal length has the focal equivalent of 48mm. It is more like a standard prime lens. Imagine a standard focal length with a fast f/1.4 aperture. A definite "bokeh" producing lens machine.
SIGMA has come a long way since Quantaray in my opinion. Their recent marketing push of their professional grade lenses has gotten much attention in the DSLR world. SIGMA quality control couple years ago has gotten some criticism such as grossly front and back focusing lenses coming out of the Japanese factory. This SIGMA 30mm f/1.4 lens gives me renewed faith, but wait! This cannot be the only choice for a budget priced and fast standard prime lens for crop sensor DSLR's ? Let me make a quick lens comparison just to be sure.
I chose two fast wide angle prime lenses priced under $600 to compare to the SIGMA 30mm f/1.4 EX DC HSM. Of course, when I mean wide angle on a crop camera I mean standard focal length close to 50mm. So the lowest priced in the group (street price around $300) and one of my favorites is the Canon EF 35mm f/2. The smallest and lightest also means slower focus due to the lack of any Ultra Sonic Motor AF system. 5mm of longer focal length means a 56mm crop equivalent. The last contender in this brief lens comparison is the Canon EF 28mm f/1.8 USM lens. Wider and faster than the EF 35mm f/2 but more expensive (street price around $530). The 28mm Canon gives almost a 45mm focal length equivalent on crop. I guess the added expense justifies the fast USM AF. The lens comparison verdict? Here are my observations.
Here is an excellent example above of the Canon EF 35mm f/2 in action. Great bokeh and the colors just pop for this value priced prime lens. Now for the bad part. No Ultra Sonic Motor auto focus means slow and gear grinding AF noises. Also, the optics are showing their 1990's age when ISO is pushed around 3200. Compared to my "L" lenses in the same ISO range, the resolution of the lens pushes it limits with high megapixel cameras such as the T3i. For the price, who can beat this quality? Well, the Canon EF 35mm f/2 lens is showing it's age but still is a favorite in my camera bag.
The widest of the group is the Canon EF 28mm f/1.8 and the most expensive. I was very disappointed with this USM lens. Although the picture above is really cute but there is no "L" pop like the other lens in the comparison. It looks flat like a kit lens. The AF is faster but that does not make up the horrible chromatic aberration in high contrast areas wide open at f/1.8. I even tried to correct the excessive purple fringing with Canon Digital Photo Professional for raw processing and correction, but no luck. Not a good choice for my camera bag, definitely.
All paths in the jungle lead to my SIGMA 30mm f/1.4 verdict. This lens is a complete dream for crop cameras. The fast aperture combined with the unique focal length makes great bokeh for still pictures and for video capture. The Hyper Sonic Motor is a close second in speed compared to the Ultra Sonic Motor of Canon's AF. The price makes the SIGMA a great value when you look at the features. SIGMA even includes a lens hood. What a deal!
Now for the SIGMA negatives. The wonderful SIGMA 30mm f/1.4 EX DC HSM is designed only for crop sensor cameras. It is the Canon EF-S equivalent for lens mounts. You can mount the SIGMA lens to a Canon 1D APS-H sensor but you will get slight vignetting. I solved that with a slight crop of the picture or the peripheral illumination correction in Adobe Lightroom. A little time consuming but manageable. Full frame cameras such as the 5D Mark II is definitely not an option with this lens.
The second negative maybe part user error and the extremely tight focal plane of f/1.4 when it comes to AF accuracy. I had my share of OOF shots at f/1.4. Although soft focus images are expected when shooting handheld, it seems a little more prevalent with the SIGMA in my unscientific opinion.
Now for the SIGMA 30mm f/1.4 EX DC HSM Video Test. Armed with various helpful DSLR cinematic tools, I captured some 1080p video with this dreamy lens. The 30mm focal length makes composition a snap complemented by the fast aperture to give great bokeh. F/1.4 is challenging when it comes to focusing the shot. Even with my trusty Zacuto Z-Finder Pro 2.5x viewfinder, achieving correct focus can test your eyesight and patience.

I mainly used the SIGMA 30mm f/1.4 EX DC HSM, Canon EF-S 17-55mm f.2.8 IS and the Canon EF 70-200mm f/4L IS Lenses. For audio, I used a Sennheiser MKE400 shotgun microphone. I also used a Manfrotto 701 HDV fluid video head with Benro 3580 tripod legs. For focus, I used a Zacuto Z-Finder Pro 2.5x viewfinder.

Equipment used: Sennheiser MKE400 shotgun microphone, Benro 3580 and Manfrotto 3221wn tripod legs, Manfrotto 701 and 501 HDV fluid video heads, Fader ND Mark II Variable Neutral Density Filter and the Zacuto Z-Finder Pro 2.5x viewfinder.
The SIGMA 30mm f/1.4 EX DC HSM is a mighty contender in the budget priced wide angle fast prime category. The recent surge in Canon lens prices due to the recent tragic earthquake and Tsunami in Japan makes other third party brands a viable choice in today's DSLR lens market. Until supply of Canon glass outweighs worldwide consumer demand, the SIGMA brand will lead and shine as an overall best value for fast lenses.
Kindergarten days are soon over. Nap times and sing alongs will soon be replaced with addition and subtraction tables. My son turns 6 years old and celebrates with a new sibling this year. Despite the foreboding end to Kindergarten nirvana and the obvious gender imbalance in the household, my mini-clone still loves a good Whoopie Cushion prank.
The "Donut King" celebrated his birthday with his classmates and his older sister's class with 60 delicious glazed rings of pure sweetness. As you might have guessed, he was voted as "Most Popular" for the day.
Fond memories of my son 6 years ago relives with my newborn daughter, Serena. The diaper changing, mixing formula and sleepless nights make a comeback in the Soriano family. Seeing my children grow in front of my eyes makes it all worth it.
My son's birthday would not be complete without a trip to Cheesecake Factory. I passed on my usual Hibachi Steak and pursued the slow roasted Beef Ribs with Onion Rings. The Cheesecake Factory special Mac and Cheese made my son's 6th birthday complete.
I have been field testing the Sigma 30mm f/1.4 EX DC HSM lens the past couple weeks for my upcoming practical review. The Sigma is designed exclusively for crop sensor cameras like the Canon EOS Rebel T3i/600D.
The scourge of baby smiles and bed wetting are things of the past now. Call of Duty :Black Ops and SOCOM 4:U.S. Navy Seals fill my son's itinerary. Hope is not lost when it comes to nurturing baby time. Serena fills the void.
