Olympus E-620 Preview

Olympus E-620

Lars Rehm and Richard Butler


Olympus has established a tradition of offering very well specified cameras in the entry-level, and was one of the first to offer two cameras in this bracket - the little E-410 and its image-stabilized big brother, the E-510 (later upgraded to the 420 and 520 respectively). Now it has introduced the E-620, a model that will 'sell alongside' the E-420 and E-520 (in the sense that we suspect it will eventually replace the E-520) as the company's attempt at a '450D-killer'.

And, even by Olympus's standards of entry-level generosity, it's not short on toys - including an articulated screen to make full use of its live view system, which itself is one of the better implementations of this feature (from the company that got there first). It's also got 'Art' modes and the ability to shoot in four different aspect ratios - adapted from the features of the recently announced E-30. There's also in-body Image Stabilization and a level of configurability that is unparalleled in this class. In fact it's astonishing how much Olympus has crammed into its small dimensions - it's nearer to the size of the E-4X0 than the E-5X0 series (due in part to use of the small BLS-1 battery), and the E-420 was famously the smallest DSLR in the world.

More importantly, perhaps, the E-620 seems to address some of the main shortcomings of the E-520 - the viewfinder is slightly larger and has been reworked so that the information panel appears below the view screen, rather than tucked-away off to the right. It also moves on from the old three-point AF system with the introduction of a seven-point version, which includes five cross-type sensors. In fact, the specification of the E-620 is so high that it makes as much sense for us to compare it to Olympus's recently introduced semi-pro body, the E-30, as to the company's existing entry-level models.

Compared to E-30 - key differences

When the E-30 was launched, we commented that it sailed remarkably close to E-3 territory, but with a smaller viewfinder and less grand claims made about environmental sealing and image stabilization. The E-620 comes close to pulling the same trick on the E-30; again the size of the viewfinder is smaller, but the cameras share the same 12 megapixel sensor, Truepix III+ processing and a great many other features. The differences between the two cameras are easier to list than the similarities:

  • E-620 is smaller (by around 1cm in each dimension) and around 180g lighter (body only)
  • Slightly smaller viewfinder with reduced frame coverage (0.96x, 95%, vs. 1.02x, 98%)
  • 7-point AF (5 cross-type) vs. 11-point (all cross-type)
  • Improved LCD (Hypercrystal III, vs. E-30s' version II unit)
  • Only one control dial (vs. E-30's two)
  • Slower continuous shooting rate (4fps for 5 RAW frames, vs. 5fps for 12)
  • Fewer aspect ratio crops (3 vs. 8)
  • No built-in digital level gauge
  • Only allows two exposures to be overlaid in multi-exposure mode (vs. 4)
  • No PC flash sync or DC-in sockets
  • Slower x-sync (1/180 sec vs. 1/250 sec) and max shutter speed (1/4000 sec vs. 1/8000 sec)
  • Lower capacity BLS-1 battery (7.2V 1150 mAh) vs. BLM-1 (7.2V 1500 mAh)

Pentax K2000 / K-m Review, January 2009,
Richard Butler & Lars Rehm

Preview based on a production Pentax K-m with firmware 1.0

The fastest-growing part of the camera market is currently being powered by photographers moving from compact cameras to DSLRs. Unfortunately for manufacturers, the added competition this has attracted has seen the prices they can charge being eroded (although it could be argued that the lower prices are spurring some of that growth). Rather than trying to slash the prices on their existing, highly-featured cameras, there has been a trend towards designing simplified cameras that can be made and sold more cheaply, offering only the features that first-time DSLR users will want without appearing too intimidating.

For many years, Pentax was often in the position of offering the least-expensive DSLR on the market with some keenly-priced entry-level offerings. However, the latest generation of down-specced and aggressively-priced models from Nikon and Sony have dramatically changed the price-conscious end of the market. Pentax has clearly been watching these developments closely and has responded with this, the Pentax K2000 (K-m in Europe).

The K2000 follows many of the trends we've previously seen in camera-downsizing, with Pentax finally giving-in to the trend of removing the top-panel LCD. It uses the K200D's sensor but comes with a simplified control layout (geared towards users coming from compact cameras) and a less sophisticated AF-system (5 points vs 11 on the K200D). The K-m also lacks the K200D's weather-sealing but in turn you get an ISO 3200 setting and slightly quicker continuous shooting.
