Sharpness at f/16 and f/22 was noticeably softer compared with the wider settings. At 100mm at f/5, sharpness was good across the frame, with f/8 being the best setting and that was the same at 200mm, where the lens performed very well – the mid focal length region was the best. Image quality at the longest setting is probably the weakest overall, but it was still very respectable and f/8 gave a sound edge-to-edge performance. With sound camera technique, you can get high-quality shots out of this lens throughout its focal length range and it’s particularly good around the 150-300mm region at f/8. WC

A big attraction of the Micro Four Thirds format is its 2x crop factor, and Olympus’s ED 100-400mm f/5-6.3 IS makes the most of that opportunity. A lens covering 200- 800mm in the 35mm format of the same aperture would likely be a monster, and an expensive one at that. Here, though, Olympus has a very usable lens that photographers who need pulling power can enjoy at a price that’s compelling. The whole focal length range is covered in one quarter twist of the zoom barrel, with over nearly two thirds of that travel covering 100-200mm, so the longer focal lengths are covered very quickly, and the lens extends by 6cm as it zooms out. A lock is fitted to keep the lens at 100mm and it’s fitted with a rotating tripod collar that usefully has a Arca-Swiss foot. The

250mm and 400mmwith shutter speeds down to 1/15sec with IS on. Impressively, I got pin-sharp shots at 100mm and 1/20sec, at 250mm 1/30sec and 1/60sec at 400mm, but it is worth saying that this is with a static subject and in ideal conditions. In practice, when the wind got up and I’d walked a mile or so, such speeds weren’t feasible and 1/250sec or 1/500sec at 400mm is more realistic. Of course, many variables come into play here, including your own physiology, and I couldn’t use this lens handheld for long. Indeed, on my trips out looking for rabbits, I alternated between a monopod, tripod or tripod/ball head/gimbal set-up. Optically, the lens delivered a sound performance at the wider apertures, which is key with long lenses, where

manual focus ring has a smooth action and is sensitive and fine in use. In terms of controls, there’s IS on/off, AF/MF and a focus limiter switch with three ranges: 1.3 to 5m, 5m to infinity and 1.3m to infinity. When the contrast or light drops, autofocus can rack back and forth, so the limiter is worth having. I tested the 100-400mm f/5-6.3 IS on an OM-D E-M5 Mark III without a battery grip. The combination is well balanced and weighs a little over 1500g, so it’s handholdable for sharp shots, but this comes with a health warning, especially when you venture towards the longer settings, and the lens’s 3EV benefit IS feature is a great help. I took sets of handheld shots outdoors using the normal shutter on a calm day at 100mm,

I loved the lens’s pulling power and, while there are technique challenges shooting at the longer settings, the effort was rewarded with good-quality results. Verdict This is a lot of lens for the money and brings super telephoto
