canon m5 review and sample image


hi, welcome to the canon 6d review. abouta year ago the canon 6d was announced by canon as the lightest, smallestfull-frame slr in the world. so, as a landscape and travel photographer this really intriguedme and i bought one of the first copies to ship. so this review isnot going to be based on marketing sheets or data sheets or anything likethat. this is going to be based on hands-on experience with the camera. i'm really excitedto be doing this review now after having used the camera for the lastyear and i've put on about 50,000 shutter actuations, so it's gottensome good use into it in the first year. so in this review we're going to take a lookat my experience with the

camera and we're going to take a look at allthe good things, the bad things, and all the stuff in between. landscape photography is a very unforgivingavenue when it comes to the conditions that equipment has to endure -saltwater, salt flats, high mountains, hail, rain, sleet, sand, snow, saltwater - theseare all conditions that the canon 6d has been subjected to, fortunatelyand unfortunately, in the past year of use. so, when first holding the canon 6d for thefirst time, the lightness and the smallness is really noticeable. infact, if you're used to using a canon 5d or a nikon d3 or a nikon d700 or a d800 or somethinglike that, in that

range, this thing is really, really light.for durability, i'd say it's extremely impact and extremely pressureresistant. so the internal frame of this camera is, of course, metal and the back and thefront plates are metal just like the 5d family bodies. but, the top caseis actually a polycarbonate reinforced fiberglass material. now, thisis different than any material that canon has put out in its full frame bodies in thepast, and the reason that canon selected to use this material is due to thewifi and the gps, to allow it to permit it through the material. thedurability and the design - really nice. ergonomics of this camera are really good, but it isslightly smaller in

physical size. so, if you can fit all fourof your fingers on the camera grip of the 5d original, 5d mark ii, 5d markiii, you can still do that on this one, but for people who have big hands, you might notand your pinky might actually be hanging off. i had some doubts about the top-case materialwhich is made of polycarbonate reinforced fiberglass, but after havinggotten it, you know, in the field and actually getting some really good use on it, it actuallyperforms very well. actually, it performs, in my opinion, justas well the magnesium alloy found in the 5d family.

canon implemented a new sensor in the 6d andthe pixel level detail of this full frame cmos sensor is capable ofproducing incredibly detailed images. i've printed large format prints from the 6d allthe way up to 40x60 inches and the level of detail is just incredible, andi'm finding that the print quality between the original 5d, 5d mark ii, 5dmark iii and 6d - they're pretty much indistinguishable from each other. i was thinking there mightbe better quality in terms of, you know, image quality and printquality but i'm seeing the same results. but, just as important asimage quality is, however, is the quality of optics in the light path - you can't overlookthat and previsualization.

as ansel adams once said, image quality isonly as good as visual quality. the canon 6d has canon's most powerful imageprocessor - the digic 5+ - and the canon 6d's digic 5+ processor is 17xfaster than a digic 4 and 30% faster than a digic 5. the image processor in a camerais responsible for reducing noise as higher iso's, among other things,and the digic 5+ represents the best to date, so the introduction of thedigic 5+ also introduced chromatic aberration correction based on canon lens profiles whichare embedded or added to the memory of the in-camera memory on the6d and the 5d mark iii. so these in-camera profiles are there for, youknow, intended to reduce chromatic aberrations

for canon's lenses, but in real world resultsi haven't really seen that much of a difference on this. so, again, thedigic 5+ is great, but what all this marketing really boils down to isbetter noise at higher iso's and higher iso's. so, one of the biggest and most importantquestions when researching, reviewing, or buying a camera is image quality.for me, it's the most important question - everything else is secondary. so, what is the image qualitylike on the 6d? well, let's take a look at a few examplesat actual size to get a better idea. so, let's take a look at this image in grandteton national park. i was there shooting a sunrise, and this is one ofmy favorite national parks. this sunrise photograph

was taken this passed fall during the nationalpark closure. now, image quality is dependent on the qualityof optics in the light path - filters, lenses, etc. so, in talkingabout image quality we're also talking about optic quality. but let's take a look at afew camera specific image quality characteristics, separate from thelens. so, let's zoom in here. i consistently see excellent colorrendition from this camera. images that come out of the camera are either typically cleanand well saturated. i actually find the color rendition to be identicalto the 5d bodies - all the way from the original 5d to the 5d markiii. that is to say it's excellent. and the

dynamic range of the 6d is excellent for thisrange of cameras. so, in this image we're getting pretty good dynamicrange between the front of the barn with the mountain peaks. and noticethe landscape just below the clouds. so, all in all, this image looks pretty good and itlooks as i remembered it. ok, let's take a look at this image. now,harsh light, harsh environmental conditions, and landscapes that will blowyour mind is what death valley is all about. let's take a look at this sunset photographwhich also doesn't have much post except for sensor dust. actually, letme show you really quick what it looks like right out of the camera. sothis is the raw file, out of the camera. again,

my post-processing work flow, in it i don'tuse much post outside of analog darkroom procedures such as dodging,burning, crop, straighten, those kinds of things, and sometimes, on someof my images, i use zero post-processing. therefore i rely on the camera to accuratelyrecord the color saturation as i remember it, and i'm finding that out-of-cameraimage quality on the 6d is excellent. ok, back to the adjustedimage here - use your video play-head to scrub back and forth below this video to get a betteridea of the before and after comparison. but, let's dive into theactual size and take a look at what we have here. so the dynamic range ofthis image is pretty typical of how the 6d

performs. there's pretty good highlight headroomin the sky here, probably could have been better if i'd used iso 100.the ridge-line sharpness is also excellent and controlled well against thesky. again, i'm just going to reiterate that the image quality is only as good as the lensand most canon l lenses are pretty good in this respect. but, fordynamic range, highlight control, and definition of the distant mountaindetails, this one is looking pretty good. the foreground of this image has wonderfuldetail in the plants and it looks like snow or ice but it's actually salt,and the salt has an incredibly high-level of detail. when printed outto 40x60 this is really impressive - the detail

here is just amazing. so, again, a lot ofthis is depending the quality of optics throughout the light path,but with high quality optics, the 6d captures detail very well and thefile is ready for print without much post-processing. now let's take a look at a sunrise photographin bryce canyon. bryce canyon national park is a pretty impressivelandscape and i think this photograph is a pretty good example of quality. notice theyellow to pink in the ridge-line in the top quadrant. the yellow to pink isa very delicate color gradient and the 6d picks up and preserves it prettywell. now you may not have guessed it by just looking at this photograph, but this was capturedin the fall. and if

you notice towards the center of the framewe have some yellow trees, and although a very small detail, onlynoticeable on close inspection of a large print or actual size like we're looking athere, it was captured pretty well by the 6d sensor. and the lower right quadrantis looking pretty good too, a decent amount of definition there betweenthe foreground and the background, not too muddy. so sharpness here is good and we'regetting a bit of lower right quadrant light fall off, but again now we'regetting into optic quality. one of my favorite parts of this image isthe gradient in the sky - a beautiful deep purple here in the top quadrant, fading intoan orange with a narrow band

of pink, then to a blueish on the horizon,leading into the distant ridge-line. the gradient and the colors here arepretty delicate and can actually be destroyed with a simple one to two stops of overexposure.and moving to the right of the side of the frame, we see that highlightshave been controlled over here pretty well as well. so, all in allthis is a pretty decent image, not the best in the world, but i think it's a good exampleof dynamic range, sharpness, and just overall image quality. so in summary, the image quality in the 6dmatches that of the 5d family all the way down to the original 5d. inother words, it's excellent but it's as you'd

expect if you are an owner of any of the camerasin the 5d family. the digic 5+ found on the 6d and 5d mark iii deliversthe best high iso noise performance found on any of the canoncameras and the color rendition and the dynamic range and saturation on the 6d perform impressively. so, canon advertises the canon 6d to be "completelysealed" from external contaminants, like the 5d family, like inthe 5d mark ii and the 5d mark iii. in my opinion, that's just marketing hype, and althoughit is very well weather- sealed, i'm not sure if it meets the hype.to give you an example, when i was shooting the sunset at the golden gatebridge, i was shooting and i had about ten

gallons of sea water dump on top of me. awave came over and broke and boom there was seawater all over everythingand with this lens and this camera. and i thought that the lens and thecamera were done for, but after i dried it off and i shaked it off a little bit, actuallythe camera body worked fine, the lens did as well, but the canon 6d performedperfectly afterwards. i don't think that after that incident aregular non-weather sealed camera would've survived. but, on the other hand, here indeath valley national park where i am right now doing this review, i actually haveto clean the camera sensor once every week or once every two weeks -it's that bad. much of my genuine excitement

about being in the natural world with a camerahas to do with close moderation of gear and carrying as littleas i possibly can. the canon 6d fits into that ultralight category and nottoo many full frame cameras do, in fact, it's one of the only ones on the market as of thisreview. so, it definitely fits into that special category of ultralightfull frame cameras and you still get that image quality that is soessential. probably the biggest feature difference between the canon6d and the 5d mark iii is the auto-focus and i often like tosay that the auto-focus is the canon 6d's

worst and best feature. there was some frictionwith the canon 5d mark ii when it was released because it had a ninepoint auto-focus system. contrast that against the canon 5d mark iiisixty-one auto-focus system. the canon 6d has eleven. so the canon 6d has the lowestlight auto-focus performance of any camera canon has introduced to date andmaybe any other still camera in this class of cameras on the market. so,what does this mean? well, if you shoot in low-light or if you shoot with nd filterson the front, or anywhere where it's difficult for the auto-focus to detectcontrast between edges then this is definitely one of the biggest featuresthat you can get on the 6d.

ok, so to summarize: if you are shooting sportsor fast action for more than 80 percent of your images this cameramight not cut it with its simple af system and its low number of af points. but, if youshoot sunsets or sunrises or if you shoot anything in low light this camerais currently the king of low light auto-focus performance, and it is, atthe moment, unparalleled. this is a huge win for me personally as i often use nd filtersand an nd filter is designed to stop light down and if you hold it up tothe light it's completely black, which means that it's really hard tocompose images, but it's even harder to manually focus. typically auto-focus stops workingwhen you reduce the stops

to a certain amount, whereas with this camerai can typically auto-focus even with the darkest nd filters on the frontof the lens. i can even shoot moonlight and have it accurately obtain a lock in the foreground. so the canon 6d is canon's first camera thatthey've implemented an integrated gps on and for commercialphotographers, wedding photographers, event shooters, this feature may not be so important,but for travel, landscape, and wildlife photographers, or any other kindof photography where accurate location based information is useful, thisfeature is going to be huge. it has a secondary benefit of not just being able to tell youexactly where you are when

you took the photograph, but it also setsthe date and time. remember in those days when you had to actually changethe time zone when you moved from one place to another? you never have to do that everagain. or remember the days when you had thousands of photos and you didn't?ok, so those are gone too. so it's a really useful feature in andof itself just for setting the time zone, but given that it also tracks your locationand for all your photographs now you have the location based information - that'spretty huge. ok, so another interesting development with gps isthat as the old professionals are predicting that google and other search engines willactually place a higher

emphasis on images with gps coordinates inthe future. so, having images that have gps data in the exif data haveinherently more seo value as a result. now although this is definitely not an advantageright now, you can at least know, feel safe to know that you're future-proofingyour images, not just for yourself right now, but also forpotential future seo. so the gps is a really useful feature and for some photographersit's a game changer, but there is one huge downside to gps and that is, isthat it doesn't have an idle shut off time. what does that mean? itmeans that if you put your camera on the shelf and leave it in the off position and comeback in a week, it'll actually

be dead. why? because the gps is drawing powerand it's enabled and it still stays on even if you turn the camerapower off, when the camera's in the off position. why? why would they do that? well, it doesn'treally make sense and you just can't try to rationalize whythey would forget that. but, it does kind of make sense in an engineeringway where if the gps were to turn off every single time that the power switch is turnedoff, well, it would have to re-engage with the satellites every singletime you turn the power on. but, why not just set an idle shut off timefor the gps? for example: the camera has an idle shut off time of, say, one minute tofour minutes to thirty minutes

to never. ok, great, so why not just put underneaththe gps menu an idle shut off time that's separate and actuallylonger than the idle shut off time of the camera. well, if canon had their guys fromthe user experience department on the clock they probably would've figuredthat out. but, as it stands right now, it's a feature that will actuallygive you dead batteries pretty quickly if you're not careful. there are a couple ofways around it. the first way is to just remove the physical battery. thatsucks, that's not really an option, but i guess it sort of is, and thesecond option is to actually add the gps to your menu. so, push the menu button and thenonce you get into the menu

you select gps, select the internal gps thenyou do in the off position. so, sort of a workaround, but not really. soagain, hopefully they can get their act together and fix this error in the future in the formof a firmware update. so the next feature i want to talk about iswifi. now this was one of the biggest hyped features on the 6d. in fact,it completely overshadowed the gps when it first came out. so, how does the wifi work,you know, is it useful, and all that stuff. well, it's utterly useless.the only two things that i can foresee you using the wifi for on thiscamera is either: a) using it for, as a remote; using your ios device or some other kind ofdevice, or b) using it to

transfer files from the camera to your computer.now, let's talk about the first one, using it as a remote. canonhas an eos remote app for the iphone and it's completely useless. they probably had oneios developer on it and they probably outsourced the guy. like, it's really,really bad. it's basically useless. not to mention there's nointervalometer on it which is, you know... how easy would it be to build that into thesoftware? really easy, right? they just forgot about it or they just didn'twant to do it. either way, the app is completely useless and you can'treally use that as a reliable remote. so, the second is transferring files and not onlyhas canon made it ridiculously complex to

set up and just basically time consuming (inother words, the time that it would take to set up, your images would already be transferredto the computer if you put it in directly into your mac.) doesn't make a lot of sense,does it? so, they've made the transferring of images via wifi overly convoluted and complexfor normal people like us and it just takes too much time, not to mention that once youdo get the connection established between the two, it's actually pretty slow. whereasan sd card typically runs between 40 and 80 megabytes per second, this thing, not evenclose. so, it's nice in the fact that the camera is, you know, quote, unquote "future-proofed"in that aspect, but at its present state it's an utterly useless feature.

so, i hope that you enjoyed this review asmuch as we enjoyed creating it and if you're able to determine betterwhether or not this camera is good or is not good for you, excellent; that was the purposeof this review. so if you enjoyed this review, check out 6dreview.com.that's where we've put all of the information that we know about the 6dand all of our hands on experience on that one site. so, there you'll find a writtenreview which has a lot more information than we were able to cover inthis youtube video, as well as a lot of high-res images. also, we have ane-book that is coming out, really soon, in fact as of this recording publish date, it'sprobably out already and the

e-book is amazing. you've got to check itout. it's completely interactive; you're able to have all the informationyou need at your fingertips, including high-res images and lots of galleries right insidethe e-book. so, feel free to check that out at 6dreview.com; it's a reallyuseful document and we had a ton of fun creating it. it took a longtime, but i think it came out really nicely. so again, check out 6dreview.com to downloadthat. for more information on this canon 6d feel free to let us knowif you have any other questions or comments, leave them in the commentsbelow - we read every single one of them, and i try my best to get back to you.
