FAQ OM System 150-400mm f4.5 Lens
What cameras is this lens compatible with?
The lens is compatible with all Micro Four Thirds (MFT) cameras, including those from OM SYSTEM/Olympus and Panasonic. However, to get the maximum 8-stop image stabilisation benefit, you’ll need a compatible OM SYSTEM/Olympus body like the OM-1.
How does the built-in teleconverter work?
The 1.25x teleconverter is activated via a simple lever on the lens barrel. When engaged, it extends the maximum focal length from 400mm to 500mm (1000mm equivalent) with a one-stoplight loss, changing the maximum aperture from f/4.5 to f/5.6.
Is this lens hand-holdable or do I need a monopod/tripod?
Despite its professional-grade specifications, at 1.875kg this lens is relatively lightweight compared to full-frame equivalents. Combined with the powerful image stabilisation system, many photographers find they can hand-hold it effectively. However, for extended shooting sessions, a monopod or tripod is recommended.
How does the weather sealing perform?
The lens features professional-grade IPX1 weather sealing, protecting against dust, moisture, and freezing temperatures (down to -10°C). All moving parts and the built-in teleconverter mechanism are fully sealed.
What’s included with the lens?
The lens comes with a protective case, lens hood (LSH-1205) with a filter adjustment window, front and rear caps, and a dedicated strap.
How does it compare to full-frame super-telephoto lenses?
When considering the Micro Four Thirds 2x crop factor, this lens provides an 800mm reach (1000mm with TC) in a much lighter and more compact package than full-frame alternatives. While the maximum aperture of f/4.5 is effectively f/9 in full-frame terms for depth of field, the shorter focal length helps maintain faster shutter speeds.
Do I need any special filters?
The lens accepts 95mm filters. While not required, many photographers use high-quality UV or protective filters. The lens hood includes a convenient window for adjusting circular polarizing filters.
What’s the warranty coverage?
The lens comes with a 3-year manufacturer warranty when purchased from authorised dealers like ourselves. Extended warranty options are available.
How close can I focus with this lens?
The minimum focusing distance is 1.3m throughout the zoom range, providing a maximum magnification ratio of 0.57x (1.14x in 35mm equivalent terms).
Will this lens work with additional teleconverters?
Yes, the lens is compatible with the OM SYSTEM MC-14 (1.4x) and MC-20 (2x) teleconverters, though these can only be used when the built-in teleconverter is not engaged.
How does The image stabilisation work?
The lens features its own image stabilisation system that works in conjunction with the in-body stabilisation of compatible cameras (Sync IS). When paired with bodies like the OM-1, this provides up to 8 stops of stabilisation, among the best available in any system.
Is this lens suitable for professional use?
Yes, it’s designed for professional wildlife, sports, and action photographers. The build quality, weather sealing, optical performance, and feature set meet professional standards.
How does it perform in low light?
While the f/4.5 maximum aperture (f/5.6 with TC) isn’t particularly fast, the excellent image stabilisation system helps maintain sharp images in lower light conditions. The lens also features a special coating to reduce flare and ghosting.
