Canon EOS 5. 0D Review. Serious amateur and semi- professional photographers are the target market for the Canon EOS 5. D - . the same market that its predecessors, the 4. D, 3. 0D, 2. 0D, .. Like its predecessors, the 5. D can be used in fully automatic point and shoot mode or anything between this mode and complete manual control. Thus, the actual market for this camera, like the others, will range from novices who want great quality images. Canon xx. D models deliver. The Canon EOS 4. 0D is a mature product - itself being the result of many upgrades over the years. Improving upon this camera is no small task. The sensor is one of the big features we typically see upgraded in a new model and this is the case with the 5. D. However, having grown used to seeing 2 megapixel increases in the APS- C- sized (1.
DSLRs. I was surprised to see a huge 5 MP increase - a 5. D. New with this review is the additional right- most column in this chart - "DLA" or "Diffraction Limited Aperture". This number is the result of a mathmatical formula that approximates the aperture where diffraction visibly starts affecting image sharpness when viewed. Along with the resolution increase each new model brings us, the narrowest aperture we can use to get pixel- sharp images gets wider. With the 5. 0D, even an f/8 aperture is narrower than optimal for on- screen pixel sharpness. Important note: The 5. D delivers higher resolution images than the 4. D and the final output size along with the viewing distance. B&H Photo - Video - Pro Audio. I buy only from these approved sources. I can't vouch for ads below. DSLRs top. Current DSLRs. NEW: Canon 6D Mk II 29 June 2017. In the film days, few people viewed their results enlarged anything close to the 1. The progression from sharp the soft is not an abrupt one - and the change from immediately prior models is not abrupt, but the DLA keeps creeping down. Check out this specific. ISO 1. 22. 33 chart results comparison. The mouseover feature will show you the degradation at f/1. As I mentioned in the Canon EF- S 1. Lens Review. there is not much optimal- image- quality aperture range left to work with when using a slow or lower quality lens. As pixel density increases, lens aberrations are magnified and more readily apparent at a 1. Thus, higher quality optics are required to make optimal use of each pixel. This is another blow to the slow lenses as they are often of a lower optical quality as well. Of course, if necessary, you can always reduce the size of the 5. D pics to get the same or better quality images. Increased pixel density also exaggerates any camera shake at capture time - increasing the value and need for IS or a good support. Increased file size is another side effect of a higher resolution sensor. Two separate identically framed scenes delivered an average RAW file size of 2. MB (5. 0D), 1. 6. MB (XSi), 1. 3. 6 MB (4. D) and 1. 1. 3 MB (XS). Shooting at full resolution is not required, but memory is cheap - why not capture all of the detail possible? If you have read any of the site's other recent Canon EOS DSLR camera reviews, you will recognize the. Click on the color block image below to view a pair of image quality comparisons between several current- at- review- time DSLR cameras. This comparison was previously featured on this page, but has been moved to its own page to avoid (especially for mobile users) the large file download required. If you read the image quality discussion on that page, you can skip down to the emboldened "new sensor". The first thing you will likely notice in the comparison is that the 4. D and XSi samples were boosted by 1/3 stop in post processing. These two cameras produce an image 1/3 stop darker at the same camera settings. Various testing results showed reasonable consistency to this difference. The actual exposure samples from the 4. D and XSi are available in the bottom set of mouseover bars for comparison. The difference is only 1/3 of a stop, but that is a helpful gain for the 5. D and Rebel XS / 1. D. Running a mouse straight down over the various camera model ISO setting labels will show you the difference in visible detail and the effective magnification of the sensor. As a generalization, higher resolution sensors show more detail than lower resolution ones. Focal length limited photographers (those needing more reach) will especially appreciate the extra detail the 5. D delivers for them (there is more headroom for cropping). As sensor density increases, so too does high ISO noise - unless improvements in the sensor and subsequent image processing are made. We have been seeing these improvements as the DSLR lines mature. What the above crops show - and what I've been seeing, is that the 5. D has slightly more noise than the 4. D at identical high ISO settings. Only a slight gain in noise from a sensor with 5. Another fact made obvious in this comparison is that the 5. D has two additional stops of ISO settings available - up to an incredible ISO 1. Well, incredible until you look at the results from this ISO setting. They are ugly - I think there is more noise than subject at 1. It looks to me like marketing wars between the competition are driving us places we don't want to be. To Canon's credit, ISO 6. ISO 1. 28. 00 are extended settings and available only after being enabled in the proper custom function. I actually had to use the extended ISOs while testing the camera. I shot a late- in- a- cloudy- day soccer game (no lights) with the 5. D and a Canon EF 4. L IS Lens. I started the game at ISO 6. ISO 1. 28. 00 and 1/6. Parents were turning car lights on to illuminate the game soon after I stopped - and the game was called just after that. The pics are poor from an image quality standpoint, but I have pics - and there was no alternative. My noise observations thus far were made with noise reduction omitted from the equation. Noise reduction is an available in- camera (Standard/Weak/Strong/None) or post- processing option. Noise reduction makes a big difference in the images - both for the good and for the bad. The good is obviously that there is less noise in the images. The bad is that noise reduction can reduce image sharpness and visible detail. The goal is to find the best compromise. The "5. 0D with NR" mouseover bar shows samples of Canon Digital Photo Pro (DPP) noise reduction settings ranging. Luminance, Chrominance) at ISO 1. ISO 1. 28. 00. I personally would rather have a little noise and retain the detail than remove all the noise and much of the detail with it. Fortunately, everyone can have their preference. Another set of mouseover bars included above are "5. D Sharpen=2" and "XS Sharpen=0" with the number indicating the DPP sharpening amount applied to the image. The Rebel XS / 1. D is so sharp at a "1" setting that moire can be seen in the image. The story behind the 5. D samples at "2" starts with the. ISO 1. 22. 33 chart results. D and Canon EF 2. L II lens. Even at f/5. I expected them to be. I next shot the ISO chart with the. Canon EF- S 6. 5mm F/2. USM Macro Lens. The results were very similar to the 1. Macro. So, I shot the same test with the amazing. Canon EF 2. 00mm f/2 L IS USM Lens. While these results were slightly better (to be expected), they were not strikingly better. The test chart is very harsh on cameras and lenses, but does show even small differences. Canon support has not been able to get me the reason for the slight softness at the pixel level, but because it is present in even the best lenses. I'm going to *guess* that the anti- alias filter may be a little stronger relative to the individual pixels on this sensor. While not quite as sharp at the pixel level, the 5. D is still pulling more detail out of the scene. The fabric example above show this. As you drag your mouse pointer up and down over the 5. D and 4. 0D labels, watch the tiny threads appear in the 5. D image that are not present in the 4. D image. Downsizing an image makes it sharper (if proper sharpening is applied) and reduces the visibility of noise. Reducing the 5. 0D image to the pixel dimensions of the 4. D results in very similar noise levels and the 5. D retains better sharpness and details. The 5. 0D has two small RAW image format options (s. RAW1 and s. RAW2) available (reduced size JPEGs are of course available). With no noise reduction applied, shooting in the 3. RAW1 format results in much less visible noise - . ISO 3. 20. 0 results actually look quite good and ISO 6. I don't find s. RAW1 images to be any sharper than RAW, but s. RAW2 (2. 37. 6 x 1. When all 3 RAW formats are processed in DPP to the 3. RAW1 size, the full- sized RAW files produce sharper details with a more fine- grained noise.
