Other than doing some simple tests, I haven’t had the need to switch from Auto Focus (AF) into Manual Focus (MF).

I've been shooting with the new Olympus 100-400mm over the past couple of weeks, so let's jump right in to see how the new Olympus 100-400mm lens performs. With the lens hood attached and the zoom retracted to 100mmm, the lens is very similar in length to the 300mm prime. Peter’s work has been published in a number of magazines including Canadian Geographic, Shutterbug and Outdoor Photographer. However, if you bought the cheaper version you will be pleased to know the difference in optical quality is not great and the 100-400 has the advantage of being much lighter and more compact.Duologi is a trading name of Specialist Lending Ltd, which is authorised and regulated by the Financial Conduct Authority (register number 774712 ). The combination of the high-resolution, high-performance lens line-up and powerful image stabilization capability results in sharp, high-quality photos and videos across a spectrum of scenarios, backdrops and conditions.

For flowers, I found myself stopping the lens down to F10 to F14 since depth of field is so narrow when shooting so close. Long telephoto lenses, especially for full-frame cameras, can easily tip the scales at well over five pounds and can approach almost two feet in length with their big lens hoods.Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. But the lens becomes extremely difficult to handle, and the tiny aperture means there’s precious little fine detail to be seen. Maintain outstanding image quality, High speed AF, and Image Stabilization performance while carrying a minimal amount of additional gear. This might sound meagre to OM System/Olympus users accustomed to getting considerably more from their camera’s in-body IS.

Its large capacity allows storage of multiple cameras and interchangeable lenses, while its overall compact size allows you to carry it on board when flying.

Like all Micro Four Thirds lenses, pixel-level sharpness visibly deteriorates if you set the aperture much smaller than this, due to the inevitable onset of diffraction.

The tiny Bushtits, which are always a challenge to shoot, decided to sit still just long enough for me to shoot a few frames.

None of the images below are cropped (as a matter of fact, of all the images in this article only the two hummingbird shots are cropped and they have only been reduced by about 20%). is an appealing lens for Micro Four Thirds photographers interested in capturing photos of distant action.When tracking birds in flight, I would often switch to the "6m-infinity" limited mode to help prevent the continuous AF from shifting wildly off-base if, or rather when, I lost track of the subject and my AF points moved over blank blue sky. The super-telephoto focal lengths do, on the other hand, help create a shallow depth of field and good subject isolation, but given the smaller sensor area of Four Thirds and the narrow apertures of the 100-400mm, in many situations, you can't get that super smooth and "creamy" background blur like you could with, say, a 500mm f/4 or 600mm f/4 lens on a full-frame platform. The Fujifilm XF 23mm F2 R WR delivers a 35mm full-frame equivalent field of view and stands out due to its small size and weather-resistant build. I don't need long exposure stabilization for wildlife, but for other shooting hand held shooting it is great.
