Canon EOS 5D II: Early Observations on Image Quality

1 Comment

I posted earlier today about increasing availability of the Canon EOS 5D II at places like B&H, so I thought it might be useful to begin posting on some of my experiences with the camera during the couple of weeks (and perhaps a thousand frames) that I’ve had it. Here is a copy of something I posted elsewhere earlier this week, in response to a post concerning image quality from this camera:

I’ve shot with cropped sensor bodies extensively in the past. I have shot with a full-frame 5D for the past two years. I recently began shooting with a 5DII and have done a thousand or so frames with it.

I cannot see image quality problems in my images, even in those that stress the ability of the camera in ways that should produce them if they are there: shooting wide dynamic range scenes, using high ISOs (up to 1600), inspecting at large on-screen magnifications, and making careful prints.

My photos have very low noise all the way through the shadows to pure black, even in some photographs where I’ve pushed the shadows either during RAW conversion and/or via the shadow/highlight tool in post. I’m seeing very highly detailed images with smooth tonal transitions. As far as I’ve seen the 5D II has a rather substantial dynamic range – as reported in a number of tests – and it is at least as great as that of the 5D.

Let me repost a couple of 100% magnification crops that I posted elsewhere from the 5DII.

The first was shot at ISO 100 at, IIRC, f/16 using a 35mm prime with the camera on tripod. The crop is a 100% magnification section from the very far lower right corner of the shot. The dark areas were pushed slightly, too, so if there were noise anywhere it would certainly appear here – but I don’t see it even at this resolution, which would be equivalent to a print width of five or six FEET wide. Seems like pretty good resolution to me! (It also speaks well for the EF 35mm f/2 lens.)

The second example is pretty much a noise “torture test” – it is a very dark section of a much larger image. (Again a 100% crop). It was shot using a 100-400mm zoom handheld at ISO 400 in cloudy conditions. There is some noise in the shot, but that is entirely normal – and this noise would be completely invisible even in a very large print. (The pattern on the lighter fabric near the left side of the frame is that of the fabric itself.)

My observations from 100% on-screen pixel peeping are confirmed by the more important test of printing.

Lowepro Nova 200 AW

1 Comment

Earlier this year I acquired a Lowerpro Nova 200 AW camera bag. I have been meaning to write my review, but I’ve managed to delay. I think this is partly a result of the nature of this bag. No, there is nothing wrong with it – in fact, I like it a lot. It is just there is nothing flashy about it either – instead it is just a very competent and useful piece of basic equipment.

‘Low End’ Cameras – Interesting Choices

1 Comment

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 EOS 5D Mark II Announced

2 Comments

This evening I’m seeing quite a few links to the announcement of the updated EOS Canon EOS 5D Mark II. (Here is a link to a Canon press release.) Unlike some previous Canon updates that seemed rather trivial – e.g. 20D to 30D – this one includes quite a few compelling new and improved features, and I’m sure this will be a very popular camera.

Some highlights include:

  1. 21MP full-frame sensor
  2. HD video capture
  3. The expected sensor dust reduction/cleaning features
  4. Live view shooting
  5. Some interesting software additions – a “new creative mode,” “peripheral illumination correction” in jpg modes (sounds like compensation for vignetting), and “auto lighting optimizer” (seems to try to deal with recording details in high dynamic range scenes)
  6. Continuous shooting at 3.9 fps
  7. Larger and higher resolution LCD
  8. 150,000 shutter cycles
  9. Expanded ISO range
  10. Price: $2699

For many of us who are attracted to the 5D image quality, the 21MP sensor is a good thing – this camera should compete with the 1DsMKIII on an image quality basis as long as one has good enough lenses and uses careful technique. (I doubt if there will be much IQ advantage if one hand holds the camera in most cases.) It is interesting to note that the increased shutter life is competitive with 1-series cameras as well.

Video capture is quickly going to be a standard feature on DSLRs – though the usefulness of the feature is something that will perhaps only become apparent once these cameras find their way into the hands of those who know how to use the feature effectively and creatively.

The relatively leisurely 3.9 fps burst mode is no surprise. The 5D is not a camera optimized for fast action sports photography that relies on high speed burst mode shooting. But still, at nearly 4 fps it won’t exactly be unusable in this regard either.

The pricing is interesting as well. Whether due to the recent announcement of a $3000 25MP full frame Sony camera and the anticipated competition from a 20+MP Nikon camera or something else, it seems that the prices of full frame cameras – and very capable ones, at that! – are starting to drop.

Will I buy one? I had pretty much decided that I would not buy a 5D upgrade that only provided a 16MP sensor. However, at 21MP this body provides close to double the number of photosites – and such a doubling has been more or less my trigger for an upgrade. Of course, I’m not one to rush to be the first to buy. I’ll let those who are willing to pay any price to be “first on the block” get theirs right away, and I like to see what initial problems are discovered as the first units are released. All of that being said, I think there is a fair chance that I’ll do this upgrade within the next 6 months or so.

Also: Canon announced one new lens, an upgraded EF 24mm f/1.4L II USM. The previous version was thought by some to be less impressive than its 35mm f/1.4 big brother, so it isn’t too surprising that Canon updated this lens. There is also some thought the Canon will update some lenses in order to take better advantage of the higher MP count sensors – they can exceed the resolving ability of some good lenses. It will be interesting to see whether the new 24mm L is a significant improvement over the previous version… and whether it is worth the somewhat shocking (for a prime!) $1699 list price.
