Đánh giá 1ds mark ii

Sixteen point six megapixels of effective sầu resolution is really nice.Of course, the Canon EOS-1Ds Mark II costs about the same per megapixel as the Canon EOS-1D Mark II- 2x as much money.

After spending a sum of money approaching 5 figures & waiting 3 months khổng lồ get the 1Ds II,I had high expectations.And I am not disappointed.I have found no unexpected surprises - vì chưng not expect to find any - and should not find any for what this tool costs.

The 1Ds II"s overall design, features (fully loaded including E-TTL II), functions, build unique, image unique (not resolution of course) ... are nearly identical to the1D Mark II.

And for the most part, this is a good thing.Canon"s 1-Series digital bodies are weather-resistant (when paired with a weather-resistant lens) & rugged.They are made lớn hold up lớn considerable và demanding use and in bad conditions.Though rugged, they have sầu an attractive, modern design.Although some may disagree, I find the Canon 1-Series body toàn thân very ergonomical.Although not light, the tactile feel và balance are excellent.The 1Ds II feels great in my h&.I find that some setting changes are not as intuitive sầu and logical as I would prefer,but I have sầu definitely acclimated to the functionality.

Of high importance to lớn most of us - the Canon EOS-1Ds Mark II focuses very fast và accurately(at least when I vày my part correctly) using a 45-point autofocus system including 7 cross-type sensors.According lớn Canon, the 1Ds Mark II focuses faster than its predecessor, the 1Ds,faster than the 1D và identical in speed to the 1D Mark II ..."Same One-Shot AF tốc độ và AI SERVO AF subject tracking performance as the EOS-1D Mark II." (Canon)I personally have noticed no focus tốc độ difference between the two mark II bodies.Canon also notes that"Because the AF unit is capable of operating at 8.5 frames-per-second và the 1Ds II has a maximum speed of 4 fps, the AI Servo AF algorithm has been optimized for 4 fps operation."

Of highest importance is image chất lượng - I am also not disappointed in any way in this regard.I didn"t find anything sacrificed in image quality to get the large 16.6 megapx image.The sensor và the related software deliver the excellent image quality I expect from Canon Digital SLRs.Dynamic range is very good (non-officially rated at 9.5 f-stops), colors look natural.Aukhổng lồ white balance is very good (I am using it more often than ever).

1Ds Mark IIII sharpness is comparable khổng lồ the Canon EOS-1D Mark IIwhen the same number of pixels are covering the subject (pixel màn chơi sharpness).This is a good thing.Sharpness seems lớn be turned up slightly by default,but post-processing resulted in similarly sharp images even though the 1Ds II has a higher px density on the sensor.There was no question that the 1Ds II delivered far more resolutionfor a similarly cropped image.And of course, if you reduce the 3:2 aspect ratio 4992x3328 px 1Ds II image lớn a 1D Mark equivalent 3504x2336 px imageand apply some sharpening, the 1DS II image easily wins.

What can you use 16.6 megapixels of resolution for?Huge prints for one thing.Think Billboards!The Canon 1Ds II"s image also has lots of cropping headroom.Even after cropping an image significantly, enough resolution can be available for a large print.Or take several crop variations out of a single shot.For those times 16.6 megapixels are not needed,JPEGs can be shot at 8.6, 6.3 và 4.2 megapixels.RAW files can be processed to lớn any desired kích cỡ when using DPP (Digital Photo lớn Pro).

Although one can never have sầu too much resolution (in my opinion),there are downsides to this - such as the resulting image file kích cỡ.1Ds II .CR2 (raw) files average 13-16 MB (& lượt thích big, fast memory cards - a 2GB CF card formats lớn indicate 109 exposures available). High chất lượng .JPG files are generally 5-8 MB,16-bit .TIF files are 97 MB và 8-bit .TIF files are 48.7 MB.These numbers are about 2x larger than the same files from theCanon EOS-1D Mark II,which has about half as much resolution.Also averaging about 2x that of the 1D Mark II are the 1Ds Mark II"s per image download (to PC) times (using a card reader) và the .CR2 processing times.I am not struggling with 16-bit image tệp tin load times or processing performance in Adobe Photosiêu thị -I expected much worse.

Of significance is the 1Ds II"s 48.7 MB 8-bit .TIF file form size.Getty Images & other of the world"s premier stochồng photo lớn agencies require a minimum8-bit .TIF file form size of 48 MB for their submissions.The 1Ds II natively meets this requirement.

The 1Ds II"s FPS (frames per second) burst rate is slightly less than half that of the Canon EOS-1D Mark II (4 vs. 8.5).To hear the difference between 4 FPS & 8.5 FPS, select each of the following sound clips.

The 8.5 FPS specification of the 1D Mark II will be the deciding factor for many sports & other fast-action photographers. The 1Ds Mark II can shoot a burst of 32 JPEGs or 11 RAW frames before filling the buffer.The single frame shutter/mirror sound of the 1Ds II also differs from the1D Mark II - It is a bit more drawn-out.

Both cameras share the same 200,000 activation-rated shutter và the same 87ms viewfinder blackout time.

One of the Canon EOS-1Ds Mark II"s most sought after features is the 1.0x full frame 36mm x 24mm sensor.The large viewfinder that comes with it is very nice.Wide angle lenses are very wide và very long lenses are required to fill the frame with small or distant subjects.But, the 1Ds II stretches even the best lenses khổng lồ their limits.Even some of the best lenses show vignetting & distortion with a wide open aperture at their shortest focal length.And, the shorter DOF (Depth of Field) for similarly-framed subjects (compared to a 1.3x or 1.6x FOVCF camera) can be good or bad.Read the Field of View Crop Factor Explanationfor more information on this feature.

The 1Ds II"s higher px density (than the 1D Mark II) will be welcomed bythose who crave sầu more focal length or magnification.Although cropping may be required to get the framing right,more detail can be captured within the same framing và using the same focal length lens as the 1D Mark II.Higher pixel mật độ trùng lặp từ khóa often means more noise in the image, but the 1Ds IIhandles this very well in my opinion.


The above ISO noise sample 100% crops are from a neutral color bloông chồng that typically shows ISO noise well.These samples were taken in bright sunlight.Because ISO noise tends to be higher in the xanh channel,you might experience more ISO noise under red-colored lighting (incandescent for example).At the same time, you might notice less noise in less-neutral colored subjects.


The above graphic above sầu illustrates the ISO 1600 noise from the 1Ds II (top) theCanon EOS-1D Mark II (bottom).Although it may not qualify for a "scientifically exact" comparison, it represents what I am seeing in side by side comparisons.These are 100% crops.Canon confirms that the two mark II bodies produce the "same low noise ..."If you don"t need the full 16.6 megapixels of resolution for a specific high ISO image, you can reduce the kích thước of the 1Ds Mark II image lớn reduce the noise appearance slightly.The bottom line - both DSLRs perform very well even at ISO 1600 - and any differences are insignificant to lớn me.


The above image is an intentionally and significantly overexposed 100% crop comparison from the1Ds II (left) và the 1D Mark II (right) khổng lồ show how the 1D Mark II does not handle over-exposed red subjects well (becoming bright pink - not enough green, too much blue).The 1DS Mark II handles this situation more gracefully.In reality, I seldom saw the overexposed reds in my 1D Mark II shots, but its nice lớn know the problem is gone.Canon - How about a firmware update for theCanon EOS-1D Mark II?

As the same tripod-mounted lens was used for each of the above sầu shots, the 1DS Mark II"s higher px density I referred khổng lồ above is also apparent.Do not use these clips lớn compare sharpness as this was the most dramatically differently coloredsection of the rose - not the focus point.

The 1Ds II powers on nearly instantly (.3 seconds vs. .5 seconds for the 1D Mark II & .6 seconds for the 1Ds)and is very responsive (setting changes, thực đơn navigation ...).Battery life is exceptional - plan on 1,200 or so shots from a fully chargedCanon NP-E3 Battery Paông xã.

Like the 1D II, the 1Ds II uses both CF & SD memory cards, each in their own slot.Simultaneous recording to lớn both cards is available for redundancy purposes.I found the 128MB SD card và 256MB CF card pictured in Canon"s White paper (below) humorous -12 và 24 exposure rolls of film come to lớn my mind. :)

Because of their near-identical features and functions,many photographers will choose khổng lồ have sầu both the 1Ds II and the 1D Mark II in their kit.There is basically no retraining or learning curve when switching bodies.After using the 1D Mark II for nearly a year, I could immediately use the 1Ds Mark II.

As I noted in my Canon EOS-1D Mark II Reviews,I found the very different landscape vs. portrait shutter release sensitivities very annoying.I also noted that Canon seems lớn have sầu fixed that problem in later-produced 1D Mark II models.I am happy to lớn report that the 2 shutter releases on my 1Ds II have sensitivities that are identical khổng lồ each other.

I"ll leave sầu you with 1 final 1Ds II thiết kế change from the 1D Mark II -the "Ds" và "Mark II DIGITAL" nameplates are now gold plated.I doubt this change will help you get better images,but at least you can look good!

Picking up a new Digital SLR means a lot of work to lớn me as I strive sầu lớn find the best post-processing workflow.Maybe I"m just getting smarter, but Canon"s DPP. (Digital Pholớn Pro - included)is giving me better results than EVU (EOS Viewer Utility - also included).I found DPPhường to give sầu me harsher looking results in the past,but EVU seems to be smoothing away some of the detail of the 1DS Mark II images.I"ve always liked the functionality of DPPhường better than EVU,but felt that EVU gave sầu me the best kết thúc result.Regardless of how I got here, DPPhường is the RIC (Raw Image Converter) I am currently using for my 1Ds II tệp tin processing.

The bottom line - The 1Ds II has arguably the highest image quality of any currently available Digital SLR.Outstanding resolution from a rugged Digital SLR that feels great in my h&, the 1Ds II delivers.I found not much lớn not like - other than the price - & the large file kích cỡ required by the 16.6 megapixel images.

If 8 megapixels of resolution is enough for you & available lenses on a 1.3x FOVCF (Field of View Crop Factor) toàn thân are wide enough for you, theCanon EOS-1D Mark IIis probably the right choice for you - I highly recommover it as well.And you can have sầu two for the same price as a 1Ds Mark II.

If you can spare the high frame rate & the cash,the Canon EOS-1Ds Mark II will give sầu you excellent high resolution images (if you vì your part of course).I highly recommkết thúc it.
