Review Sigma Mc-11 Canon Glass to Sony Alpha 7 Camera

Flexibility. Quality. Range. The current flow of photographic technology is turning, though arguably, toward the incredible imaging power packed into mirrorless camera systems. These smaller and lighter camera bodies pack dSLR resolution and ISO performance into housings that are shockingly compact.

Still, many shooters are seemingly reluctant to switch from their tried and true camera systems with justifiable apprehension. The reason? They feel as if they would be starting from scratch; needing to purchase completely new lenses to match their new mirrorless camera systems.

This is non the case. While the technology has been floating around for some time, converters/adapters have now began maturing to the point where virtually whatsoever lens system, fifty-fifty those with advanced autofocus and profiles, can be used to full issue with power-punching mirrorless camera set ups. But not all adapters are created equal.

Enter the Sigma MC-11 converter ↓

The MC-11 addresses the well established need of many users to arrange their Sigma lenses (currently Canon and Sigma mount just) to be used with Sony Eastward-Mount cameras. The MC-11 has been long anticipated by those who have made the jump to Sony mirrorless photographic camera systems such as the α7 series also every bit NEX, α5000, and α6000 series . Yous may exist asking, "volition this adapter work with lenses other than Sigma?"… well, not officially according to Sigma. Don't worry. We'll talk more than about that before long.

Before we get into the performance of the MC-11 (which proved impressive) let'southward have a look at some of the features which make the MC-11 a welcomed improver to the lens converter scene.

Structure Quality and Features

Structure of the MC-11 adapter is, in a discussion, beautifully utilitarian. I know that's two words but one only would not do. It sports completely metal construction of what feels to be aluminium.

The indicator markings are well done and highly visible. The converter is finished in a heavy duty matte black coating. The forwards release switch is aggressively grooved for easy operation. The USB port (more on this later) is weather sealed to keep out all the nasty bits of clay and moisture that can be encountered in the field.

The converter feels quite solid and mounts very cleanly to the A7R MK1 test photographic camera used for the review. The lens provided by Sigma for testing with the converter is the 24mm f/1.4 DG HSM Art which the adapter also mated to tightly. Aesthetically, the lens and converter matched fantastically.

If you are the type of shooter who wanted form to equal function so the MC-11 converter will not disappoint.

Y'all volition find also that the inside of the converter is carpeted with a black felt material. This is called "flocking" and is nowadays on higher stop mountain to mount converters. The reason for this flocking is to foreclose and internal reflections that sometimes occur from using adjusted lenses particularly at wide apertures. This is a great feature that I was relieved to notice included on the MC-11. Well done, Sigma.

Briefly we mentioned earlier about an interesting characteristic of the MC-11 and this is the inclusion of a port for connecting the converter to your computer via USB cable (included). This allows the converter's firmware to be updated as they are released from Sigma. Equally new lenses get available for use with MC-11 the photographer tin abound with the times just by updating the converter's firmware. The port itself is protected past a fold-back rubber gasket.

Lens Compatibility

The MC-xi converter of form works with the bulk of Sigma's glass including their Contemporary, Sport, and Fine art lines of lenses. At the time of this writing in that location are 22 total lenses which are compatible with the MC-11 and that number continues to grow. As it stands, simply Canon EF mounts and Sigma SA Mount versions of the converter are available. Sorry Nikon users.

Hither's a full listing of compatible lenses from the Sigma website.

12-24mm f/4 DG HSM (Art) 24-35mm f/two DG HSM (Art) 24-105mm f/4 DG OS HSM (Art) 120-300mm f/2.8 DG OS HSM (Sports) 150-600mm f/5-6.3 DG Bone HSM (Sports) 150-600mm f/5-6.3 DG OS HSM (Contemporary) 20mm f/1.4 DG HSM (Art) 24mm f/1.iv DG HSM (Fine art) 35mm f/1.4 DG HSM (Art) 50mm f/i.4 DG HSM (Art) 85mm f/i.4 DG HSM (Art) 500mm f/four DG Os HSM (Sports)	17-70mm f/2.viii-4 DC MACRO Bone HSM(Contemporary) 18-35mm f/1.8 DC HSM (Art) xviii-200mm f/3.5-6.3 DC MACRO OS HSM (Contemporary) eighteen-300mm f/3.5-6.3 DC MACRO OS HSM (Gimmicky) 50-100mm f/1.8 DC HSM (Art) 30mm f/i.iv DC HSM (Art) 19mm f/ii.viii DN (Art) 30mm f/2.8 DN (Art) 60mm f/ii.viii DN (Art) 30mm f/1.4 DC DN (Contemporary)*2

A keen little feature of the MC-eleven is the LED indicator light for lens compatibility. There is a small LED light close to the base of the adapter that lets you see if the lens you accept fastened is compatible with the MC-eleven adapters current firmware.

The light's color and frequency tells you lot a number of things well-nigh the lens you have attached to the converter:

• Greenish light: The lens is compatible.
• Blinking greenish light: The lens firmware needs to exist updated using the SIGMA USB dock.
• Blinking orange low-cal: The lens is uniform but the MC-11 requires an update to retrieve new lens information.
• No light: You guessed information technology… the lens is not compatible.

Autofocus Operation and Compatibility

One matter that certainly weighed heavily on my listen earlier I evaluated the MC-xi was merely how well autofocusing would carry over from the lens. Some adapters I've used in the past worked not bad for the cost but accurate and reliable AF was always the achilles heel. The MC-11 converter offered alarmingly speedy AF when used in conjunction with the 24mm f/i.4 Art lens (Canon EF).

I was honestly surprised at just how well it performed both in terms of speed and accuracy. Here is a quick video displaying the real-world speed of the AF capability of the MC-xi with the Sony A7R MK1. Focus way was single shot flexible spot mode "M".

When it comes to whether or not the MC-11 converter will piece of work with lenses other than those made by Sigma… again, officially the answer is no. In practise however, the verdict upgrades to a strong "maybe". While information technology's true that the MC-xi was engineered to requite full functionality to Sigma-made lenses in terms of AF and firmware there is too jerk room for usage with Canon EF lenses every bit long equally yous don't mind some loss in AF variety and function. Reports range from good to terrible operation when using Canon lenses with the MC-11.

In my examination, I mounted a Canon 50mm f/1.4. The lens fastened perfectly and communication with the photographic camera seemed to exist fine. Using my Sony A7R in full-frame fashion, the AF was somewhat lacking. Oftentimes the camera would not focus at all. When it did, timing was extremely wearisome at around three to four seconds until lock. Oddly enough, when I switched the camera to APS-C mode the AF came to life and focused accurately in under one second.

Continue in mind that the LED indicator light did non illuminate when I attached the Catechism lens meaning information technology is completely non-compatible with the firmware of the converter. With that being said, using a Catechism lens with the MC-11 is not outside the realm of experimentation. Just continue with caution.

Now just for fun, hither are a few images made using the Sigma MC-xi mount converter with the Sigma 24mm f/1.4 DG HSM Art…

Last Impressions

Afterwards using the MC-11 converter at that place is no dubiety that the folks at Sigma take managed to produce a solid piece of gear that tin can open upwardly a entire new spectrum of lenses to those who utilise Sony mirrorless cameras. The converter is built like a tank, looks swell, and falls onto a happy middle ground between college priced mount converters. What's better is that with the add-on of the USB port the converter can grow with engineering giving it staying power in the photo gear world.

Functionally, the converter performs as advertised and depending on your expectations perhaps even better. The AF speed with my Sigma test lens were neat and that was the selling point for this writer. This is certainly a converter that I would use daily without hesitation.

Y'all can find the Sigma's MC-11 converter on Amazon equally well as via Sigma's website.
