Some reviewers have expressed concern over the smaller battery powering the E-410. In order to fit it inside the small handgrip it uses a 1150mAh Li-ion cell, rather than the large 1500mAh units that power most other DSLRs, including the E-510. I’d have to agree that heavy use of the live monitor view would probably shorten the battery life somewhat, but I don’t think this will be a problem for most users. The majority of people will prefer to use the optical viewfinder, since this is one of the main advantages of the SLR design, and will treat the live view as what it is; a useful extra feature that is used only when needed.
Since the E-410 has the same sensor, lens and image processor as the E-510, it’s not surprising that the image quality is also identical. The 10-megapixel Four Thirds sensor, while physically smaller than the APS-C sensors found in most other DSLRs, still produces an equivalent level of fine detail, and high ISO noise control is as good as anything else on the market. As with the E-510, there is perhaps marginally less dynamic range than an equivalent APS-C camera, but if so it is barely noticeable. All in all, the E-410 produced extremely good image quality under all circumstances, despite the lousy weather available during my test period.
Although currently slightly more expensive than some of its competitors, the E-410 has several advantages, not least its compact dimensions, low weight and useful live view feature. It also offers fast performance, extremely high image quality and a very wide range of creative control. If you want a highly portable DSLR and aren’t too bothered about image stabilisation then the E-410 would make a rewarding enthusiast’s camera.
