Using Prints to Test Four Canon DSLRs

Miles Hecker has posted interesting test results in his Canon EOS big guns image quality shootout:

As some of you know, I am a landscape photographer. I migrated to full frame digital SLR’s from medium format film. I used to shoot 6×4.5, 6×7 and 6×9 film with the end product being prints of 20″x30″ and larger. As such, I chose to investigate only one area of the 5Dmk2 in this exercise, overall image quality or IQ for short. For this test, I decided to construct a still life with a wide range of color, lots of detail and very controlled lighting to obtain what for me are valid results.The test would produce 100% crops for pixel peeping. The final analysis of IQ however would be made using real life obsevers and detailed sections of 16″x24″ and 20″x30″ photographic prints.

What I like about his test methodology is that it eliminates the very difficult issue of normalizing on-screen tests of cameras with different sensor sizes and photosite densities but doing something that I have felt would make the most sense, comparing large prints from the different test cameras. In this case he tested the Canon EOS 1DsM3, 5D2, 5D, and 50D. 

I won’t spoil the fun by telling you the results here, but let’s just say I’m not at all surprised at the results.

In Praise of the Canon 5D II, and Why I’ll Wait a Bit Longer

I’ve used the Canon 5D for the past few years, and it is a very fine camera for most types of photography and an excellent camera for my photographic purposes. I find the advantages of the full frame sensor to be compelling: potentially higher image resolution, a greater range of useful apertures, the ability to shoot at smaller apertures than on cropped sensor cameras, and so forth. Any criticisms of the camera that I might have are truly minor. (A mirror lockup button would be nice… ;-) Other photographers have agreed, and the 5D has probably been the most popular full frame DSLR until now. It is a favorite of those who shoot landscape, and I’ve seen people using it successfully to shoot almost any type of subject.

Given the relatively brief product life of DSLRs – they are often replaced by updated/new models in as little as 18 months – many had been expecting an update to the 5D for some time. When Canon announced and released the new 5D Mark II (5D II or 5D2 for short) this fall, the excitement among Canon photographers peaked. At some discussion forums I read you might find that half of the posts concerned this camera at times!

The specifications explain why the 5D II is such a compelling camera. The photosite density of the full frame sensor has been increased, and the new model has a 21+MP sensor, nearly double that used in the original 5D- but with higher ISO capability, greater dynamic range, and no increase in noise. It incorporates newer Canon DSLR features including “live view,” an exciting HD movie mode, Canon’s sensor dust reduction system, the ability to fine tune the auto-focus system to your lenses, increased “weather resistance,” and more. All of this and the price has actually dropped a few hundred dollars from the list price of the original 5D. 

Many photographers have gone to great lengths to be the very first to get the new camera. They have signed up on “waiting lists.” Some have paid pre-order fees so that they would “have dibs” on the first boxes to arrive. Others frantically post on forum boards asking which dealers have one in stock, and are apparently ready to drive great distances to pick one up. I’ve even seen a few posts in which the writer offered many hundreds of dollars as a “finders fee” to anyone who would locate a 5D II. And you can be quite sure that all of these folks are paying full list price (and more) for their new cameras.

Not me.

There is a pretty decent chance that I’ll get this camera eventually, but I’m in no big hurry to be the “first on my block” to get one. Here are some of the reasons:

  • My existing 5D produces quite good image quality already. While the 5D II is capable of “better” resolution, the difference is certainly one of degree and not a “night and day” difference. When I make good sized prints, sensor resolution is rarely the limiting factor – whatever enlargement limit I encounter is more likely due to focus issues, lens issues, camera motion issues, and so on. Already having a camera that is capable of capturing images with excellent resolution, I’m know that I do not need to rush to get the incremental improvement that the 5D II might provide.
  • I prefer not to be a beta tester.  There is a very good chance that problems will be discovered when the first production run of any product finds its way into the hands of end users. Nothing against the manufacturers (in the majority of cases), but when many thousands of photographers use a new camera it should not surprise anyone that certain subtle issues emerge. In fact, it appears that this may have already happened with the 5D II. I read today that Canon has released a statement acknowledging that they are looking into two issues: “black dots” that appear to the right of bright highlights in some images and banding issues that appear when certain settings are used. Based on my previous experience with Canon, I’m confident that they will resolve these issues, but I would just as soon wait until after that happens.
  • Why pay list price? You don’t have to be an economist to know that the price of an item will be higher when the demand is highest. When a new product is released, typically after a marketing buildup and plenty of “buzz,” there are many buyers who are so excited that they will pay almost anything to get it. Now. No matter what. The manufacturers and retailers are willing to oblige them. ;-) You can get one of the first copies of a camera like this, but you are almost certain to pay a premium for the privilege. If you need the camera right now you don’t have much choice. But if you already have a camera that can produce fine images (like my current 5D) there is little rational reason to buy immediately at the higher price. In a few months we’ll undoubtedly see the price begin to drop.

Here’s my bottom line on the 5D II: I think that it looks like a really fine camera. It provides a very compelling feature set at a very reasonable price. If I didn’t already have a good camera that serves me pretty well, I’d probably plan to pick one up fairly soon. However, I’ll wait until the initial bugs have been identified and fixed in the manufacturing process and until the price softens a bit.

‘Low End’ Cameras – Interesting Choices

An interesting juxtaposition caught my attention this morning.

Yesterday Michael Reichmann posted a very interesting article (“You’ve Got to Be Kidding“) in which he compares the image quality from the (arguably high end point and shoot) $500 Canon G10 with that obtained from his high end Hasselblad medium format digital system. While some are misrepresenting the point of his article to be that the G10 is equal to the Hassy MF system (it isn’t, and he didn’t write that), the significant point is that for many uses the G10 can produce good size prints (13″ x 19” in Reichmann’s article) that are largely indistinguishable from those that came from the MF camera.

At about the same time I saw a link to a dealmac.com posting about sub-$600 prices for the Canon XSi 12.2MP APS-C DSLR with the quite decent EFS 18-55mm image stabilized lens. Anyone who looks at the features of this camera objectively and knows about the generally quite good reviews of this lens understands that this is a tremendous value for a camera system that is more than capable enough for the vast majority of DSLR purchasers.

So, on one hand we have a small almost pocketable camera (the G10) that can produce excellent quality prints as large as most people will ever produce (much larger, in fact). If your point of comparison is DSLRs of a year or two ago – $1000+ in many cases – this is a quite amazing thing, and could induce many buyers to think about the G10 or a similar camera, either as the camera or as an adjunct when traveling light is important. But wait, the cost of a quite decent DSLR isn’t $1000+ any more – it now appears to be perhaps only $100 more than that of the G10.

Canon 50D Announced: Competition is a Good Thing

News of Canon’s announcement of the new EOS 5D cropped sensor mid-range DSLR is all over the web today – well, at least all over the photographic portion of the web. The new body updates the X0D line from the recent 40D, primarily by updating the 1.6x cropped sensor to 15 megapixels. According to Canon this was done while increasing the performance at high ISOs, keeping the burst rate almost the same as that of the 40D, and maintaining image quality by the use of “gapless microlenses” that can capture more light than would have been the case with older designs. There are other feature updates as well, and it looks like the price will be roughly but not precisely in the same ballpark as that of the 50D… at least once the prices drop a few months after the introduction of the new camera.

What does this mean for the DSLR buyer? The answer is, “It depends.” Continue reading Canon 50D Announced: Competition is a Good Thing
