‘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.

Lowepro Slingshot 350 AW Introduced

Leave a comment

I’ve written before that I’m a big fan of the Lowepro Slingshot AW line of camera packs, especially the Slingshot 200 AW camera pack. I’ve used mine extensively and it provides a good mix of capacity (enough for a body and a few lenses), convenience (carries over the shoulder with one strap), accessibility (swings forward for easy access to gear), low price, and weather protection (built-in weather cover). I especially like it for urban photography where I can keep all of the necessary gear close and accessible while traveling on foot.

Now I see that Lowepro has introduced a new larger model, the Slingshot 350 AW that is designed to hold not only more photographic gear, but also to carry a laptop. I have not yet had a chance to see the bag in person or try it out, but if it works the way I would expect based on experience with the Slingshot 200 AW it sounds like it could be a dynamite bag for travel and especially for air travel.

Wide Angle Lenses and Image Stabilization

Leave a comment

I often hear people claim that image-stabilization is only of value on normal to long focal length lenses, and is not useful on wide angle and ultra wide angle lenses.

The photograph posted earlier today was shot handheld on a full frame DSLR at 1/25 second at ISO 800 and 32mm. (32mm on full frame is equivalent to using a 20mm focal length on a 1.6x cropped sensor body.)

I had just finished a session of tripod-based landscape shooting on the summit of this dome, had packed up, and was heading down when the lone hiker crossed the ridgeline below me just as some lovely post-sunset light gently illuminated the landscape. Having no time to set up a tripod – hiker and light would have been gone by then – I dropped everything, pulled the camera with image-stabilized 24-105mm lens from the pack, made some quick seat-of-the-pants exposure calculations, and got of three quick frames before the scene was gone. Without IS I simply would not have gotten a usable version of this photograph – a photograph that has since been licensed for use in a print journal.

Even as one who often shoots from a tripod – and almost always carries one – I have found the notion that IS has no value at shorter focal lengths to be a myth not born out in actual practice.
