Rank #8 in Best Telephoto Zoom Lens 2026: 8 Ranked, and Two Spec Sheets That Don't Add Up
OM System M.Zuiko 150-600mm f/5.0-6.3 IS
Price and rating as shown on Amazon when we collected them. Both change.
The OM SYSTEM M.Zuiko Digital ED 150-600mm f/5.0-6.3 IS is a Micro Four Thirds ultra-telephoto zoom priced at £1,850.00, ranked 8th in this guide. It is the one entry here whose aperture figures read the right way round: 5 f as the maximum and 22 f as the minimum, where the Sony and Nikon lenses in this category both have theirs swapped.
The focal length column is where this listing goes wrong. It gives a maximum focal length of 1200mm and a minimum of 300mm, which are the 35mm-equivalent figures from the marketing bullets rather than the 150-600mm on the barrel, and it then lists a 'fixed focal length' of 600mm for a lens the same table calls a zoom with a ratio of 4. Stabilisation is listed as 'Digital' in the spec table while the bullets claim up to 7 stops of compensation. Every figure on this page is taken from the Amazon listing for this lens, not from testing of our own.
