              First let me start off by saying, I will use ANY tool for the job! As long as that tool gets the work done, produces the BEST image, and is the easiest for me to work with (means I get 99% of my image by keeping focus at all times; don't miss shots due to camera features, etc).

              I mainly work in the video medium, so the focus peaking, higher DR on just all about all of Sony's A-mount (57 on up), phase detection AF in either video or photog, was some of the defining factors for me when choosing which systems to go with.

              I don't hate Canon, and well, Nikon uses Sony technology anyway. I am not a fanboy of ANY product; I just really love what these alpha cameras can do!

              Hell, strip the brand off and call it "Sewer Water Mark I", and I still would choose the a99, a77 / a77 II, a57 over just about any other camera in their respective ranges. The a77 II even has zebras now! And DON'T say, "you can get all that with ML." I have USED ML on Canons, and while it's better than nothing, it's still wonk.

              I am a professional videographer, and dynamic range is one of the most IMPORTANT features of any camera. The higher the DR, the better image quality you can grade in post. Also, phase detection AF in video mode is supremely important. It's a great feature that I use a LOT.

              Comparisons for video / photog:

              Canon 60P @ 1080 = no; A99 60P & 1080 = yes
              A99 has much higher DR
              A99 less shutter lag (BY A LOT); more cross type & focus points; faster max shutter; dual CARD SLOTs!
              A99 has better image quality

              I do mainly commercial work for businesses, but I also do a bit of wedding / event videography on the side – as well, I have a photography background to base the above and following observations on.

              Phase detection is hands down better for AF than contrast, and in a wedding or even scenario AF is freakin' essential.

              Also, don't you WANT better image quality? I mean, I do. I guess if you want to shoot in a closet where it's dark, perhaps the 6D would be preferred, but that is a ridiculous scenario. Higher MP pixel count means more options for larger print sizes.

              Plus, Snapsort always lists Canon as having more lenses...they need to take into account that all of the old Minolta Maxxum AF lenses work with ANY Sony A-mount, and some of those old lenses are amazing(beer-can lens; the old 50mm 1.7)!

              Lower noise at higher ISO is my first consideration when choosing any type of body, and I am sure it is for most SLR users (SLT in Sony's case). However, if you are shooting at a wedding, you are going to be using a FLASH. You are more than likely going to be using SEVERAL DIFFERENT BODIES, and what's more, SHOOTING RAW. If you are shooting JPG, and complaining about noise at any ISO level, shame on you. 25K ISO max with a FF sensor and higher DR is going to be a negligible comparison if shooting RAW or video, at best in this comparison.

              In video, I will gripe that AVCHD is more noisy than H.264; however, both are compressed formats. AND, if you are doing this for real (as your source of income), chances are you are using an external recorder...AND, if you are doing that, you are going to get a MUCH better image from the a99 – especially in post due to the above mentioned specs. It's really not even a contest...

              How can the 6d beat the a99 other than Canon is a more popular brand of camera? Looking at the comparison, doesn't image quality and better dynamic range trump lower noise at higher iso?
              Battery life? here is no guesswork when using evf so you'll be taking less shots. Thus you'll be consuming a less battery.
              And the a99 has the 6d beaten to a pulp on the video department.
              Btw, you forgot to add that a99 can shoot at 1080p @ 60fps and is good for slow-mo.
              hams (11:48 AM, November 25, 2013)
              how does popularity affects camera performance and quality? and why do EVF viewfinder got zero points at all? like no viewfinder at all. fyi EVF nowadays is improved a lot and most camera cos. invest on it too... you should update your criteria.

              The major drawbacks on the Sony SLT-A99 and SLT-A99v:

              1. Battery life sucks.
              2. Lousy tethered shooting software over free Canon's.
              3. Software won't allow to save on card /or card and computer like Canon's can.
              3. Software has NO True Tethered in live-view and video recording like Canon's.
              4. CAN NOT do wireless shooting unless you purchased the ATG AK1 Un-Tethered Systems.
              Dual live-views are very important for beginners to pros daily shooting stills & videos.
              5. You must buy the vertical grip (dead weight) to get long battery life without breaking door.
              6. No on camera's flash menu like Canon for shooting wireless flash.
              7. Instruction manual's written for nuclear scientists to understand.
              8. The Sony hotshoe is a NOT standard hotshoe.
              So many quacks are saying it is. Putting many flashes & wireless radios will not work.
              9. Sony HVL-F60M sucks.
              The world's first expensive speedlight that ever came out from China, cost more than C&N.
              It's overheat & shutdown very quickly. Canon 600EX-RT (Nikon SB-910) is a little better.
              Very long delayed when shooting outdated wireless line-site flash.
              CAN NOT use place flash head in softbox to get wireless flash like others can.
              A useless LED video light that is only good & fun for your children use as a flashlight.
              10. 1/250 Flash Sync is a FAULT ADVERTISEMENT!
              Try it out when shooting wireless flash, that if you can afford two or more flashes.
              Again, you will get a wireless flash delayed when you are shooting slight moving subject.

              FYI: Basic kit that beginners get will cost over

              Sony SLT-A99 is $2,799.00
              Sony 24-70/2.8 is $1,799.99
              Sony HVL-F60M is $548.99
              Don't forget about tax

              That's over $5,200.00 USD
