# Best Telephoto Zoom Lens 2026: 8 Ranked, and Two Spec Sheets That Don't Add Up Source: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses Published: 2026-09-18 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-18 Two of the listings below print the aperture range backwards. The Sony 200-600mm calls its maximum aperture '6.3 Millimetres' and its minimum '5.6'; the Nikon 180-600mm repeats it as '6.3 f' and '5.6 f'. The numbers are swapped, and the unit is millimetres, not f-stops. A 6.3mm opening would be a pinhole, not a 600mm super telephoto zoom lens. Nikon's listing also claims 'effective still resolution: 20 MP', which is a camera specification, not a lens one. Any best telephoto zoom lens ranking built on those fields would be nonsense. So if you are shopping for the best telephoto zoom lens, the eight below were ranked on three things that survive checking: the focal range printed in the product name, the price, and how the star ratings actually fall. Sony's 200-600mm takes first place with 86 per cent of its 842 ratings at five stars. The cheapest lens here, Canon's RF 100-400mm at £599, still reaches 82 per cent. Meanwhile the two lowest five-star shares sit at 71 and 72 per cent, and one of those two carries 13 per cent one-star ratings. That spread tells you more than any aperture field on the page. ## The ranking ### 1. Sony 200-600mm f/5.6-6.3 G OSS Super-Telephoto Zoom - Price: £1,599.00 | Amazon rating: 4.7 from 842 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/sony-200-600mm-g-oss - Buy on Amazon: https://www.amazon.co.uk/dp/B07T26V9ZN?tag=ranked10-21 The best telephoto zoom lens here on the numbers that hold up: 86 per cent of 842 ratings at five stars, across a 200-600mm range. This is the best telephoto zoom lens here on the one figure no listing can fake: 86 per cent of its 842 ratings are five stars, with only 2 per cent at one star. The 3:1 zoom ratio covers 200mm to 600mm, and the £1,599 price sits below the Canon EF 100-400mm L and the Nikon 180-600mm. Crucially, none of that depends on the aperture field, which on this listing reads '6.3 Millimetres' for maximum and '5.6' for minimum — inverted, and in the wrong unit. In practice the optical design is what the price suggests: five ED elements and one aspherical element, an 11-blade circular aperture, and Nano AR coating to cut flare and ghosting. A DDSSM focus motor drives autofocus for stills and video, and built-in Optical SteadyShot handles handheld work at 600mm. The 95mm filter thread is the practical detail to note — filters that size are not cheap. That said, this is a Sony E-mount lens and nothing else, so Canon, Nikon and Micro Four Thirds owners should stop reading here. It is also a buy-once lens: at 600mm the f/6.3 maximum at the long end demands light or high ISO. If you mostly shoot in dim woodland, a faster short telephoto will serve you better. Pros: 86 per cent of 842 ratings are five stars, with just 2 per cent at one star; 200-600mm range with a 3:1 zoom ratio, stated the same way in name and specs; Five ED elements plus one aspherical element, and an 11-blade circular aperture; Nano AR coating and built-in Optical SteadyShot; Priced £1,599 — below the Canon EF L and Nikon Z 180-600mm listings here Cons: Aperture fields are inverted: '6.3 Millimetres' maximum, '5.6' minimum; Sony E-mount only, with no adapter route for other systems; 95mm filters are an unavoidable extra cost; f/6.3 at 600mm is dim; the listing also carries 'file format: MP4', which is not a lens specification ### 2. Canon RF 100-400mm F5.6-8 IS USM - Price: £599.00 | Amazon rating: 4.6 from 754 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/canon-rf-100-400mm - Buy on Amazon: https://www.amazon.co.uk/dp/B09G8J5WNZ?tag=ranked10-21 The closest thing to a budget telephoto zoom lens here at £599, with 82 per cent of 754 ratings at five stars. Cheapest of the eight at £599, and second on rating distribution: 82 per cent of its 754 ratings are five stars. For a Canon EOS R body this is the sensible entry point into long glass, and 754 ratings is a large enough sample to trust. Worth noting, the aperture fields here read '5.6 f' maximum and '8.0' minimum — plausible on their face, unlike the Sony and Nikon listings. The engineering trade is clear: 635g and 164.7mm long, with a 5.5-stop optical stabiliser and STM autofocus that is quiet enough for video. A 67mm filter thread keeps accessories affordable, and Ultra-Low Dispersion glass handles colour fringing. For a telephoto zoom lens for wildlife photography days out, that 635g weight matters more than any f-number. However, f/8 at the 400mm end is slow. The stabiliser buys handheld sharpness, not subject separation or low-light headroom. If you shoot sport under floodlights or wildlife at dawn, this lens will push your ISO hard. The listing's own copy also calls the stabiliser 'shock correction up to 5.5 stops', which is not the term Canon uses. Pros: £599 — the lowest price of the eight here; 82 per cent of 754 ratings at five stars; 635g and 164.7mm long, with a 67mm filter thread; 5.5-stop optical stabiliser and quiet STM autofocus for video; UD glass and Air Sphere Coating in the optical path Cons: f/8 at 400mm — slow in anything but good light; Canon RF mount only; no EF or EF-S bodies; 400mm is the shortest full-frame reach in this group; Listing copy describes 'shock correction', which is not a Canon term ### 3. Sigma 150-600mm F5-6.3 DG DN for Sony E - Price: £1,199.00 | Amazon rating: 4.6 from 206 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/sigma-150-600mm-dg-dn - Buy on Amazon: https://www.amazon.co.uk/dp/B09BWGXRDM?tag=ranked10-21 A 600mm telephoto zoom lens for £1,199, backed by 81 per cent of 206 ratings at five stars. This is the best telephoto zoom lens for Sony owners who want 600mm without the Sony price: £1,199 against £1,599, with 81 per cent of its 206 ratings at five stars. The focal range is consistent everywhere it appears — 150-600mm in the name, and 150 and 600 in the spec fields. In practice you get a 4:1 zoom ratio, nine diaphragm blades, up to four stops of optical stabilisation, and a minimum focusing distance of 23 inches. It is smaller and lighter than the conventional version of this lens, and the 95mm filter thread matches the Sony 200-600mm. On a Sony body, autofocus and stabilisation work without an adapter. The catch is in the numeric fields. 'Maximum Aperture' reads '6.3 Millimetres' — the same millimetres-for-f-stops error as the Sony — and 'Screen Size' is listed as '23 Inches', which on a lens means nothing at all. Even so, 206 ratings is a modest sample next to Sony's 842, and 3 per cent of them are one star. One bullet is also truncated mid-word: 'in. focusing distance of just 23 inches'. Pros: £400 cheaper than the Sony 200-600mm at £1,199; 81 per cent of 206 ratings at five stars; 150-600mm range stated consistently in the name and the spec fields; Up to four stops of optical stabilisation with a 4:1 zoom ratio; Minimum focusing distance of 23 inches; 95mm filter thread Cons: Maximum aperture recorded as '6.3 Millimetres'; 'Screen Size: 23 Inches' is meaningless for a lens; 206 ratings is a smaller sample than the Sony and Canon listings; One bullet is truncated, and nothing in the listing mentions weather sealing ### 4. Nikon NIKKOR Z 180-600mm f/5.6-6.3 VR - Price: £1,689.99 | Amazon rating: 4.3 from 117 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/nikon-nikkor-z-180-600mm - Buy on Amazon: https://www.amazon.co.uk/dp/B0C8J5BH7B?tag=ranked10-21 £1,689.99 buys 600mm and weather sealing, but 72 per cent five-star is the second-lowest share here. Nikon's 180-600mm reaches 600mm for £1,689.99, and 72 per cent of its 117 ratings are five stars — enough for fourth place. But 8 per cent of buyers give it one star, double the one-star share of the Canon RF and Sigma listings. Its aperture fields repeat the inversion exactly: '6.3 f' maximum, '5.6 f' minimum. The listing then adds 'effective still resolution: 20 MP', a camera figure on a lens page. In practice the design leans on handling: internal zoom keeps the barrel length constant, in-lens Vibration Reduction steadies the view, and the Z TELECONVERTER TC-2.0x takes it to 1200mm while still shooting handheld. Weather sealing and a lightweight build make it a lens you carry rather than park on a tripod. At 600mm the f/6.3 maximum applies, whatever the field says. That said, 117 ratings is a small sample compared with the 842 behind the Sony lens. There is also a straight contradiction in the table: 'Fixed Focal Length' is given as 180 Millimetres on a lens named 180-600mm. If you shoot Sony or Canon, this is irrelevant. If you shoot Nikon Z and want the best telephoto zoom lens for that mount, it is the only native 600mm option on this page. Pros: 600mm reach with internal zoom for balanced handheld shooting; Z TELECONVERTER TC-2.0x extends the reach to 1200mm; In-lens Vibration Reduction plus weather sealing; 72 per cent of 117 ratings at five stars; 95mm filter thread, matching the Sony and Sigma lenses Cons: Aperture inverted again: '6.3 f' maximum, '5.6 f' minimum; 'Effective still resolution: 20 MP' is a camera specification; 'Fixed Focal Length' listed as 180 Millimetres on a 180-600mm zoom; 8 per cent one-star, and only 117 ratings behind the score ### 5. Canon EF 100-400mm F4.5-5.6L IS II USM - Price: £1,909.40 | Amazon rating: 4.2 from 370 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/canon-ef-100-400mm-zoom - Buy on Amazon: https://www.amazon.co.uk/dp/B00PGNMXQA?tag=ranked10-21 The fastest aperture here at f/4.5 and the highest price at £1,909.40, but 71 per cent five-star is the lowest share. Two numbers stand out: £1,909.40, the highest price of the eight, and 71 per cent five-star across 370 ratings, the lowest five-star share here. It also carries 13 per cent one-star ratings, the worst on the page. That is an odd pairing for the lens that has been the default telephoto zoom lens for sports photography on Canon DSLRs for years. In practice the L-series build is what people pay for: fluorite and Super UD elements to suppress chromatic aberration, a USM motor with full manual override, an adjustable zoom touch ring, and 77mm filters that cost noticeably less than the 95mm glass on the 600mm zooms. It fits Canon DSLRs directly and EOS R bodies with the EF-EOS R adapter. Even so, this is the messiest listing of the eight. Minimum aperture is given as '38 f', the coating as '[POSSIBLE] Super Spectra coating', and the table also lists a 'screen size' of 1 inch and a media type of ProductImage. None of that is a lens specification. However, f/4.5-5.6 is genuinely the fastest maximum aperture in this group, so if you already own a Canon DSLR, it is still worth a serious look. Pros: f/4.5-5.6 — the fastest maximum aperture of the eight; Fluorite and Super UD elements; USM with full manual override; Adjustable zoom touch ring for resistance control; 77mm filter thread, cheaper than the 95mm zooms; Fits Canon DSLRs directly and EOS R bodies via adapter Cons: £1,909.40 — the most expensive lens here; 71 per cent five-star and 13 per cent one-star, the weakest spread on the page; Minimum aperture listed as '38 f'; 'Screen Size: 1 Inches' and 'Media Type: ProductImage' are not lens specs ### 6. OM System M.Zuiko 100-400mm F5.0-6.3 IS II - Price: £1,024.00 | Amazon rating: 4.6 from 44 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/om-system-100-400mm-is-ii - Buy on Amazon: https://www.amazon.co.uk/dp/B0DV96LZ1K?tag=ranked10-21 £1,024 for 800mm-equivalent reach in a 205.6mm body, with a small 44-rating sample behind the 4.6 score. On Micro Four Thirds the 100-400mm covers 200-800mm in 35mm terms, for £1,024 and 1,300g. It is the cheapest route to that reach here, and 73 per cent of its 44 ratings are five stars. By contrast, the Sony's 4.7 rests on 842 ratings, so treat the two scores differently. The sample is the caveat: 44 ratings is about a twentieth of Sony's total. In practice this is the best telephoto zoom lens for a Micro Four Thirds body when you want to keep walking: 205.6mm long, 1,300g, up to 7EV of in-lens stabilisation, and compatibility with the MC-1.4 and MC-2.0 teleconverters. Dust and splash sealing is certified to IPX1, with a fluorine coating on the front element. The 72mm filter thread is modest compared with the full-frame zooms. The catch is in the fields. 'Minimum Focal Length' reads 400 Millimetres — the same as the maximum — and 'Fixed Focal Length' is given as 40 Millimetres. Meanwhile the 800mm headline is a 35mm equivalent, not an optical figure. If you shoot full frame, this lens is not for you; the mount is Micro Four Thirds only. Pros: £1,024 — the cheapest 800mm-equivalent reach here; 1,300g and 205.6mm long; Up to 7EV in-lens stabilisation; MC-1.4 and MC-2.0 compatible; IPX1 dust and splash sealing with fluorine coating; 73 per cent of 44 ratings at five stars Cons: Only 44 ratings — a thin sample for a 4.6 score; 'Minimum Focal Length' listed as 400 Millimetres, equal to the maximum; 'Fixed Focal Length: 40 Millimetres' contradicts the 100-400mm name; Micro Four Thirds only; the 200-800mm figure is an equivalent, not optical ### 7. Panasonic Leica DG Vario-Elmar 100-400mm F4.0-6.3 - Price: £1,239.00 | Amazon rating: 4.4 from 35 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/panasonic-leica-dg-100-400 - Buy on Amazon: https://www.amazon.co.uk/dp/B0CJDNMKYL?tag=ranked10-21 985g and 0.5x magnification for £1,239, backed by only 35 ratings and 9 per cent one-star. Three figures matter here: 985g, £1,239, and 35 ratings. The first is the lightest build in this group, and 75 per cent of those 35 ratings are five stars. But 9 per cent are one star, and a sample that small, which means the score moves easily — a single review is worth roughly three percentage points. In practice the Leica-certified optics plus Power OIS make it a video-friendly choice, with smooth aperture transitions and 0.5x magnification, or 1.0x with the DMW-TC20 teleconverter. Splash, dust and freeze resistance covers most British weather. The 200-800mm equivalent range matches the OM System 100-400mm, at a higher price. However, the numeric fields are as confused as any here. Maximum focal length is listed as 800 Millimetres and minimum as 200 — those are equivalents, not the 100-400mm printed on the barrel. 'Fixed Focal Length' reads '100400 Millimetres', the coating is named in Italian, and an ISO range of 100-25600 appears on a lens listing. Either way, 35 ratings is the smallest sample on this page, so buy on the specification and the weight, not the star average. Pros: 985g — the lightest lens in this group; Leica-certified optics with Power Optical Image Stabilisation; 0.5x magnification, up to 1.0x with the DMW-TC20 teleconverter; Splash, dust and freeze resistant; 75 per cent of 35 ratings at five stars Cons: Only 35 ratings, and 9 per cent of them are one star; Focal lengths listed as 800mm and 200mm — equivalents, not the 100-400mm range; 'Fixed Focal Length: 100400 Millimetres' is not a specification; ISO range and shooting modes listed on a lens page ### 8. OM System M.Zuiko 150-600mm f/5.0-6.3 IS - Price: £1,850.00 | Amazon rating: 4.4 from 29 ratings - Full review: https://www.ranked10.co.uk/tech/best-telephoto-zoom-lenses/om-system-150-600mm - Buy on Amazon: https://www.amazon.co.uk/dp/B0CSZ3KP1F?tag=ranked10-21 300-1200mm equivalent reach for £1,850, with 78 per cent five-star but 11 per cent one-star from just 29 ratings. This is the longest reach here: 300-1200mm in 35mm terms, extendable to 2400mm with a teleconverter, for £1,850. It is also the best telephoto zoom lens in this list for pure magnification. The rating spread is the problem — 78 per cent of 29 ratings at five stars, but 11 per cent at one star, and 29 ratings is the smallest sample on the page. In practice the 600mm focal length is real on the barrel, and the seven-blade diaphragm is the fewest listed among these eight. Stabilisation is quoted at up to 7 stops, which is what makes handheld 1200mm-equivalent work possible. Autofocus is described as fast and the close focus distance short for a lens this long. That said, one field describes the stabilisation type as 'Digital' while the bullet points claim in-lens compensation — the two do not agree. In theory the listed maximum focal length of 1200 Millimetres is the equivalent figure, not an optical one. If you need reach beyond 800mm equivalent, this is the only option here. If you want a large body of user reviews behind the score, it is the weakest on the page. Pros: 300-1200mm equivalent, up to 2400mm with a teleconverter; Up to 7 stops of stabilisation compensation; 78 per cent of 29 ratings at five stars; 600mm real focal length in a compact body; Fast, high-precision autofocus and a short close focus distance Cons: 29 ratings — the smallest sample here; 11 per cent one-star, the highest of the three Micro Four Thirds lenses; Stabilisation type listed as 'Digital' while the bullets claim in-lens; Seven diaphragm blades, the fewest listed of the eight ## Verdict The Sony 200-600mm is the best telephoto zoom lens in this group for most full-frame shooters: 86 per cent of 842 ratings at five stars, a clean 200-600mm range, and a price below the two most expensive listings. If your budget is tighter, the Canon RF 100-400mm at £599 is the best telephoto zoom lens for Canon R bodies, and the Sigma 150-600mm at £1,199 is the equivalent answer for Sony E. For Micro Four Thirds, the OM System 100-400mm at £1,024 delivers 800mm-equivalent reach at the lowest price here. Either way, read the spec table with the scepticism these eight listings have earned — the focal range in the name and the price tag are the two numbers that never contradict themselves.
