Canon EOS 6D vs 5D Mark III Reviews

CNET compares the Canon EOS 6D vs 5D Mark III vs Nikon D600 and writes;
“In terms of autofocus performance, the 6D acquired a focus lock on subjects quite quickly and accurately. Autofocus speeds were also good in dim light, and seems to live up to the company’s claim that the shooter’s autofocus system was as sensitive even at -3 EV (low-light levels).”
Rating: ★★★★☆

Kenrockwell compares the Canon EOS 6D vs 5D Mark III vs Nikon D600 and writes;
“Technical image quality should be identically excellent. 20 versus 22 MP is invisible; either has more than twice as many pixels as anyone needs for anything. The 6D improves on the 5D Mark III by putting the play, zoom and trash buttons where they belong: on the right side. The 6D adds up/down/left/right control to the big rear control dial, and thus eliminates the need for the old thumb nubbin.”

Canon EOS 6D User Reviews

A small, capable, conservative full-frame DSLR ideal for new buyers
“STILLS IMAGE QUALITY: Excellent. Per-pixel sharpness is very high and superior to crop bodies– par for the course for a full-frame sensor near this pixel density. Dynamic range is similar to the 5D II and 5D III. Noise performance in raw is a third-stop better than the 5D III and about one stop ahead of the 5D II.” – By D. Alexander

6D vs 5D Mark III and Nikon D600
“After spending the night taking several comparison photos at ISO 3200 F4 1/125, 6400 F4 1/500, 12800 F4 1/250 and 25600 F4 1/1000, here is my conclusion. Photoshop enlarged at 350% shows the 6D has about a one stop advantage over the 5D Mark III and 1-1/2 stop over the Nikon D600. That did not come as a surprise since the 6D has the lowest resolution among the 3 DSLR.” – By E. Lin
Rating: ★★★★★

1st day impression review
“They image quality is superb, and low light is what you would expect from a full frame camera. The Af is disappointing if you are coming from a 7d and is similar to the Af on the old 5d mark II. Canon could have just put the same AF system as the 7D in here and this camera would be a must buy.” – By Chao Lee

Canon EOS 5D Mark III User Reviews

Excellent Camera
“I can’t say enough things about the new autofocus system. AMAZING. GENIUS. I rarely have eyes out of focus now. Even my 85mm/1.2L is performing much better. I love the colors and creaminess from that lense but focusing it was like playing a Russian Roulette game.” – By Lissi G
Rating: ★★★★★

Solid upgrade to a great camera
“The 24-105 lens is a great lens especially stopped down to about F8. good contrast and edge detail, at the wide 24mm side there is a little bit of barrel distortion… but it is so minor most will not see it and if you are using a program like lightroom it is very easy to fix” – By J. Crawford
Rating: ★★★★★

5D Mark 3 Surpasses Expectations
“Image quality in real world shooting has been amazing. I’m not sure how much to add to this at this point. I have had 2 official shoots so far and the resulting pictures were fantastic.. I have used it with my 24-70 L and 70-200 L and the results have been most pleasing.” – By CanonInBama
Rating: ★★★★★

5 star step up
“I am highly impressed with the image quality of this camera. Images come out very true to life and are crisp. My first impression: Blown away with the quality. The detail, even when zooming in is crisp and to the point.” – By Theresa

5D MK III Canon’s Best FF Camera Available (Until 1DX!!)
“The high ISO capabilities and quality at high ISO’s is nothing short of astounding! Not only is the high ISO quality great, but I love, love, love the QUALITY of the noise. I have read it several times and I do concur – the noise on the 5D III is film like -it looks more like grain than noise.” – By John Gerald Carnessali “happy man”
Rating: ★★★★★

Bought it for the AF, but got a whole lot more
“Its like Canon took the very good AF system of the 7D and hyped it up with steroids and sonar – it’s that good! There was no way they were going to let the AF system handicap this camera – and they’ve succeeded.” – By D. K. Miles “dkmiles1”
Rating: ★★★★★

A substantial upgrade
“This camera blows the Mark II out of the water. Focusing alone is amazing. Video looks great. I am a video professional and this camera was a no brainer for me. For anyone looking to get a great stills camera and very solid video camera- this is the one.” – By john street
Rating: ★★★★★

My new favorite camera
“I used Av mode with Auto ISO ( Auto ISO set to Max range ). I try to keep Av at f8 unless I have a depth of field, shutter or ISO issue. The 61 Point AF worked well but I also used single-point Spot AF alot. Auto WB was excellent.” – By David Brandenburg
Rating: ★★★★★

A home run for the 5D series, finally
“Camera startup and operation is near-instant. Shutter lag and mirror blackout is now faster than before and leads to a more instant, responsive feel while shooting. This, combined with the vastly improved AF make for a radically different experience from previous 5D bodies.” – By J. Howell
Rating: ★★★★★

Exactly what I wanted
“I am extremely comfortable shooing up to ISO 25,600 with the 5D3. Images are still very detailed with very nice looking, fine grain. Images don’t become flat looking and still have a really nice look to them. I will even shoot 51,200 without a problem, although there is a big increase of noise beyond the native ISO values.” – By Invertalon
Rating: ★★★★★

A huge improvement in almost every way
“Mark III has professional-level autofocus now, with a wide array of cross point locations (exact number varies depending on the lens you are using), and very fast focusing speed. What was a major down-side is now a major up-side.” – By Phil Rosenthal

5D Mark III = Underpriced Baby 1DX
“the low light performance tests I’ve seen and what I’ve now experienced with the Mark III makes it the most amazing night shooter in this price range.” – By Alex F

About the perfect FF camera if you shoot Canon glass
“Much easier to catch birds in flight even with f5.6 glass), 6 Fps (plenty of FPS for weekend BIF warrior / Sports photographer, AF during video using AF button, better high ISO capability (combined with low light AF) is completely worth the price of admission.” – By A. Datta
Rating: ★★★★★

Initial impressions– an AMAZING camera
“The ISO performance is no less impressive. The Mark II already was a great performer at high ISO, and the Mark III is even better. Stunning, nearly noiseless results all the way to ISO 6400. And still incredible results all the way to ISO 25600.” – By E. Lacey
Rating: ★★★★★

4.8 stars
“Better AF, 100% viewfinder with electronic grid (no more screens), better LCD, faster drive and processor, fabulous shutter/mirror, 7-stop bracketing, 2-axis level, somewhat lower noise and thus somewhat cleaner images vs. 5D2, two card slots, uses same batteries as 5D2.” – By Coronet Blue

Canon 5D III, has night vision, or so it seems
“Feel is great! One thing that amazed me is the pictures I took at night without flash! I was amazed! its as if it has night vision! Looking forward to learn all its features. I am upgrading from the 7D which I intend to keep as my companion camera.” – By EGodoy
Rating: ★★★★★

An amazing upgrade coming from 7D
“The lack of noise is amazing, and when there is noise…it’s very pleasing to the eyes and doesn’t take away from it. I’ll be honest, when it was officially released i didn’t think it was too impressive of an update…but the more i use it the more i realize how nice of a camera it is.” – By K. Xiong “callaesthetics”

A concise review from a wedding photographer
“Exposure compensation has been greatly increased (+-5!!!), FPS is now at 6, which for any wedding/sports/action photographer is a HUGE plus; The AF system is much faster and more accurate (the old system was EIGHT yrs old!)” – By DOBrien “Photo reviews.”
Rating: ★★★★★

Best low light performance
“I’ve had the camera for about a week now and it’s a great update to the 5dII and a step up from the 7D. Better construction, better AF, the high ISO quality is really outstanding even at 12,800 and useable up to 25,600 for the web.” – By Ethan Gardella
