Olympus E-P1 – a size comparison

In a release that they’ve hyped for weeks now, Olympus finally pulled the covers off their first Micro Four-Thirds format camera, the E-P1.

Good product photography - sure looks dainty doesn't it?

Good product photography - sure looks dainty doesn't it?

For those of you not already in the know, Micro Four-Thirds is a new interchangeable lens system developed by Olympus and Panasonic which is the first mirror-less digital camera system to feature interchangeable lenses.  The removal of the mirror (and associated prism and optical viewfinder) and the exclusive usage of live view for image preview enables a drastic size reduction for both cameras and lenses, and as you can see here, the new Olympus E-P1 is tiny tiny tiny.

How tiny?  The exact specs on the E-P1 are 121 x 70 x 35mm (4.7 x 2.8 x 1.4 in) and 335 g (11.8 oz) – body only, with no batteries – which firmly plants it in compact camera category.  Of course, you’ll need to attach a lens at some point before shooting, which will add some bulk, but as of now the E-P1 indisputably offers the most compact interchangeable lens solution.

The following is a run-down of things you might have already picked up from other news sources or blogs. The real interesting stuff is the size and equivalent aperture/focal length comparison, at Size Comparison.

Camera Guide, June 2009

I get a lot of questions all the time about which camera to buy, and most of the time I don’t quite have the time to respond to all of them, so I’ve decided I’d start a regular camera guide feature.  These aren’t in-depth rationales or anything, just quick summaries that tell you, unequivocally, which is the best of the best; I also write digital camera recommendations for a site called bestinclass.com – I might recommend visiting there if you’re looking for more in-depth analyses and comparisons.

Digital cameras don’t come out all that often, so this may be a quarterly guide.  This also may not reflect the very cutting edge – it takes a little while for reviews for the newest cameras to come in, and it’s impossible to really assess the cameras until they do.

All prices based on the lowest of amazon.com or bhphotovideo.com

Have you got a use case/need that isn’t covered here?  Feel free to post it in the comments, and I’ll keep it in mind for future guides.  And if you think differently about any of the cameras, feel free to share that too!

General advice:

To give you all an idea of the perspective these recommendations are written from, here’s a few guidelines I mostly go by:

Features trump image quality: With modern cameras, image quality differences are mostly a consideration of the past.  Almost every camera released today has megapixel resolution far in excess of what’s needed (or even usable) for most applications, and in most daylight scenarios there is practically zero difference between cameras, especially among the top tier of manufacturers.  The main differentiator in your photographic experience and capability, then, is what features you’ll have to work with – being able to take a wide shot with a 28mm wide-angle lens, or having a fast 4fps continuous shooting mode for action shots, for instance, is going to go a long way towards getting you the photographs you want compared to minute differences in image quality or resolution.

Price/performance: The recommendations for different categories will mostly recommend the camera with the best value proposition – a lot of these are often written in the format of: Best budget camera under $200, best midrange camera under $300, best premium camera under $500, etc. While oftentimes, yes it’s true that Camera Xa has a slightly bigger LCD screen than Camera Xb and is therefore better, and the $50 premium still puts it under the $300 budget, as a knowledgeable consumer you wouldn’t want to spend that much more on a mostly cosmetic difference, and as an informed friend you would do best by recommending Camera Xb to your friend.

Simple Ultracompact

For many people, cameras are just cameras, and all they need is something that, for lack of a less-hackneyed phrase, they can “point and shoot”.  They’re not interested in photography and don’t need nor want full manual controls, and rarely would use and can make do without a huge zoom range.  They’ll take snaps while they’re out at social events or just randomly at home or in their room, but that’s about it.  For this group there’s the simple ultracompact – a basic camera that has a few useful features (possibly wide-angle lenses for indoor group photos and image stabilization for low-light situations) but otherwise just provides good overall quality and a small formfactor that can be slipped just about anywhere.

Simple Ultracompact, midrange: Canon SD960

A plethora of Canon, Panasonic, and Fujifilm cameras rule the roost in the ultracompact category, all roaming around the $300 range.  For a little less than $300, Canon’s SD960 puts together the best combination of image quality and features, with a 28mm wide-angle, image stabilization, and even 1280×720 (720p) video capability.

  • 12MP resolution
  • 28-112mm (4x) zoom range
  • f/2.8-5.8 aperture
  • 1280×720, 30fps video (720p)
  • Image stabilization
  • 145g (5.1oz)
  • 99.1 x 53.3 x 22.9 mm (3.9 x 2.1 x 0.9 in)
  • 200 shots battery life (CIPA)
  • $281 on Amazon

The Demosaic Project

So over the past couple of weeks I’ve been working on a little project called Demosaic.  It’s a little online demo that interpolates image data from (simulated) raw sensor output, similar to what almost every digital camera used today has to do.
