The Sony a9 is touted as the Jack of all Trades. Impressive specs, and a lot of hype coming from a devoted fan community.
However, all that glitters is not gold. The video below, shot with a Sony a9 using a $9000 Canon EF 500mm f/4 lens on a Sigma MC-11 adapter, isn’t so impressive after all. The Sony a9 is not able to track focus after the shutter has been fired. The Sony a9 just started shipping so we don’t know if this phenomenon is limited to adapted Canon lenses (guess it is).
If you are a professional photographer, stick with Canon and Nikon and stay safe with proven gear and great and reliable professional service. If you have money to waste for gadgets, get a Sony a9. The specs are truly impressive and once more show how much Sony is pushing technological innovation.
Photography Blogreviewed the Sigma 500mm f/4 DG OS HSM Sports lens, a pro lens selling at $5,999 and still being substantially less expensive than Canon’s counterpart, the EF 500mm f/4L IS II USM.
From the conclusion:
The Sigma 500mm f/4 DG OS HSM Sports lens is a much more affordable alternative to similar lenses from Canon and Nikon without any sacrifice in image quality or performance. […]
The Sigma 500mm f/4 DG OS HSM Sports is tack-sharp at both the centre and edges of the frame when stopped down by one-stop, and it’s also very good even when shooting wide-open. Vignetting is apparent at f/4, but it almost completely disappears by f/8, or it can be easily removed in post-processing. Chromatic aberrations are noticeable only by their absence, and distortion is very well controlled too. Optically, there’s very little to complain about.
Build quality is excellent, with the brass lens mount and sober all-black design adding to the high-quality feel and the dust/splash-proof construction adding some peace of mind, plus there’s a very good carbon fibre lens hood and padded case. Read the review…

The Sigma 85mm F1.4 Art lens will be available in late October and retails for a recommended street price of $1199.00 USD.
Sigma 12-24mm F4 DG HSM Art Ultra-Wide Angle Zoom for the Era of Ultra-High Resolution Digital Cameras
Boasting the renowned Global Vision image quality from center to edge, the new Sigma 12-24mm F4 features the largest aspherical glass mold in the industry, offering photographers an ultra-wide angle zoom with virtually no distortion, flare or ghosting. Encompassing the long history of Sigma wide angle lens development expertise, the new 12-24mm F4 performance highlights include constant F4 brightness and the brand new Sigma AF system with 1.3X torque boost. The 12-24mm F4 features lens elements made with FLD (“F” Low Dispersion) glass, which is equivalent to calcium fluorite in performance. Combined with an optimized power distribution, the result is outstanding image quality from center to edges. With a minimum focus distance of 9.4 inches at 24mm, photographers can compose incredible close-up shots with expansive backgrounds.

Sigma 500mm F4 DG OS HSM Sport Lens – Pro Fast-Aperture Prime Super Telephoto
The flagship Sigma super telephoto 500mm F4 Sport lens incorporates the very latest in Sigma optical technology and innovation. Designed for the professional sports and wildlife shooter, the ultra-durable lens features magnesium alloy components, a carbon fiber hood, a water and oil resistant front element, and is dust and splash proof.

Tested for Optimum Performance
Sigma lenses are born of well thought-out design concepts, exceptional Japanese craftsmanship and manufacturing, and advanced lens performance testing and evaluation. To this end, Sigma has developed its own A1 proprietary MTF (modulation transfer function) measuring system using 46-megapixel Foveon direct image sensors. Even the most elusive high-frequency details are within the scope of Sigma’s quality control inspections. Every Global Vision lens is A1 tested, analyzed and approved before leaving the factory, ensuring maximum performance out of the box.

It appears that Sigma will enjoy us with more lenses based on their new technology. Various lenses that will be part of the “Sport” line-up may be announced. The rumor fits with the rumored list of next Sigma lenses we posted aome time ago.
The rumor has word that Sigma will announce first a 300mm f/2.8 OS and a 400mm f/2.8 OS lens. These lenses may be undergone field-testing during the Winter Olympic Games. The other lenses Sigma is said to work on are a 500mm and a 800mm lens.
Ever wondered how a Canon L lens is made? Well, there is a three part video series (by RazorFantasy) that covers each and any aspect of the manufacturing of the EF 500mm F4L IS USM lens. Above is part 1, below part 2 and 3. Enjoy!
