And while Panasonic lenses autofocus as you would expect on OM cameras, they are tuned for Panasonic's own DFD contrast-detect AF system – and some notable examples (such as the Panasonic 20mm f/1.7) focus incredibly slowly on non-Panasonic bodies. Overall, we think that OM System lenses are just that bit snappier on OM System cameras.

Covering an equivalent range of 16-50mm, this deceptively capable zoom goes from a wide field of view to standard. It's great for street shooting.

We test lenses using a mix of both real world sample images and lab tests. Our lab tests are carried out scientifically in controlled conditions using the Imatest testing suite, which consists of custom charts and analysis software that measures resolution in line widths/picture height, a measurement widely used in lens and camera testing. We find the combination of lab and real-word testing works best, as each reveals different qualities and characteristics.

The last lens you'll ever need? Not quite, but with an equivalent range of 24-400mm and sharpness to die for, this superzoom lens is pretty darn close.

When you're looking for the best Olympus lenses, you're also looking for the best OM System lenses, as the range is undergoing a transition from one name to the other. You're also working with the Micro Four Thirds mound, meaning you can also use Panasonic lenses – however, as we'll see, there are plenty of reasons why users of Olympus or OM System cameras might want to stick with lenses by the same brand.

Measuring a mere 58x42mm and tipping the scales at just 137g, this diminutive lens feels right at home on even the most compact MFT format body. Like the Olympus 17mm that we favor for street photography, this one is available in either a silver or black finish, and the hood is sold separately. Naturally, the 2x crop factor of MFT cameras gives this lens an effective 50mm focal length, delivering a classic ‘standard’ viewing angle with a fairly fast f/1.8 aperture rating. Image quality is impressive in all respects. Considering the prices of Canon and Nikon 50mm f/1.8 lenses for full-frame cameras, the M.Zuiko doesn’t look terrific value. However, its performance fully justifies the price tag.

With its short telephoto focal length and wide f/1.2 maximum aperture, this sumptuous (and hefty) professional lens is ideally placed for portraiture.

With a whopping 200-800mm equivalent focal range, this telephoto zoom lens packs a wallop, and can even be extended further with teleconverters.

However, while you can fit Panasonic lenses on OM System bodies without any obvious issues, Panasonic's lens stabilization doesn't always play nicely with OM's in-body stabilization, and you get better results from switching off the lens O.I.S.

Amazingly affordable, this lens is ideal for anyone who wants to cover a telezoom range on a budget – and it's also incredibly small and lightweight, too.

While it carries the OM System badge, this is really just a minor refresh of one of Olympus' oldest Micro Four Thirds lenses – however, it's still one of the most desirable. It arrived alongside the company's first PEN cameras and the standard kit lens back then, another retracting design, this one a 14-42mm. The Olympus 9-18mm doesn't go as wide as other, more recent Olympus ultra-wides, the f/4-5.6 maximum aperture is a tad restrictive and the retracting mechanism is not a deal breaker but it is a bit of a faff. Even allowing for all that, though, this lens's size, light weight and ultra-wide angle of view make it a unique proposition for travel photography and interiors, and dated as it might look, there's still nothing like it today.

OM System now offers a few 40-150mm telephoto zooms: this one is tiny, light and… well, let's not pretend, more adequate than spectacular. But you can forgive a lot in a telephoto zoom that's this small and this cheap. It's equivalent to an 80-300m lens in full frame terms, but a fraction of the size and price – it's a reminder of the advantages of the Micro Four Thirds format over APS-C and full frame systems. Yes, the sensor is smaller, but so are the lenses – often spectacularly so. Some may prefer to get the newer OM System M.Zuiko 40-150mm f/4 Pro for its IP53 weather-sealing; however, we think the incredibly low price of the Olympus M.Zuiko 40-150mm f/4-5.6 R means it merits inclusion in this guide.

In each section in this guide we've picked out what we think are the stand-out candidates and we explain why. It's worth bearing in mind that these categories are not set in stone – you can capture fantastic landscapes with telephoto lenses, just as it's possible to capture a characterful portrait with a wide-angle. However, these categories are a good starting point for thinking about the kinds of lenses you want to use.

One of the best pancake lenses, when fitted to something like the Olympus PEN E-P7 you can slide your camera into a jacket pocket or a handbag and take it anywhere. We've all had to accept cameras and lenses getting bigger and bigger and bigger over the past few years, but this lens, on a compact PEN body, takes carry-round cameras right back to the size they ought to be!

Olympus makes five telephoto zooms and we only have space for three – but we still want to give a mention to the other two. The M.Zuiko 75-300mm f/4.8-6.7 II looks amazing, with its 150-600mm effective focal length, but the truth is it's not the sharpest knife (or lens) in the box. And while the M.Zuiko 150-400mm f/4.5 TC1.25X IS Pro is a spectacular 300-800mm f/4.5 ultra-telephoto, it is a massive lump of a thing, with a price to match. For sports and wildlife pros it's a must-have dream lens, but probably not for anyone else.

This lens delivers an impressive 114-degree viewing angle, which is no mean feat on a Micro Four Thirds camera. Its contrast and sharpness are utterly sublime.

We pick the best Olympus lenses (OM System) to get right now, from compact primes to professional constant aperture zooms

Whenever you buy any kind of serious OM-D body, this lens will be one of the bundle options. It's kept the same design for years, but that's not because it's some kind of low-cost throwback that's just used for lens bundles – it's because the company got everything right with this lens from day one. Its 24-80mm effective zoom range is just a tad longer than the 'standard' 24-70mm on other cameras, and its optical performance is consistent right across the zoom range. It can also focus very close for a standard zoom lens too, so it's very versatile. If you had to choose one standard zoom lens for your Olympus, this is the one to get. Also, note that there is a newer rebadged OM System version of this lens – the OM System M.Zuiko 12-40mm f/2.8 Pro II is virtually the same, but has added weather-sealing.

OM System makes so many excellent prime lens that picking just three to represent the whole spread was VERY difficult. With that in mind, we have to mention some lenses that aren't on the list but deserve maximum respect. They include the M.Zuiko 8mm f/1.8 Fisheye Pro (how is an f/1.8 fisheye even possible?), the compact and classy 35mm equivalent M.Zuiko 17mm f/1.8, the big but tasty M.Zuiko 25mm f/1.2 Pro, the dinky little M.Zuiko 30mm f/3.5 Macro, the equally dinky and ridiculously cheap M.Zuiko 45mm f/1.8 portrait lens, the amazing 150mm equivalent M.Zuiko 75mm f/1.8 and the remarkable M.Zuiko 300mm f/4 IS Pro telephoto prime. Phew.

Right from the moment you pick this lens up you can feel the Olympus Pro lens quality in its design and operation – and our lab tests have shown that its optical quality does not disappoint, either. This is another unique lens, this time because of the focal lengths it straddles: you could see it as an ultra-wide zoom that goes right up to a standard zoom range, or as a standard zoom that also goes ultra-wide. Either way, this one lens could replace two lenses for many travel, street and architectural photographers. It's not particularly small, to be fair, but the focal range it covers is quite impressive

The 180mm equivalent focal length gives you plenty of telephoto reach, and if it's not enough, you can pair it with OM System’s M.Zuiko MC series teleconverters to double it to 360mm. If you're looking to photograph macro subjects that won't let you get too close like flighty insects, this is a fantastic asset – though naturally, you'll need a good deal of precision and potentially some quick reflexes to get them in the frame.

Sick of changing lenses? Want an all-in-one solution? OM System reckons it has cracked it with this impressive 16x optic, covering everything in between a wide 12mm (24mm equivalent) perspective to a telephoto 200mm (400mm equivalent). And, by and large, they've done it! The lens is great to use, delivering impressive results from a body that's not only lightweight and easy to carry, but is also weather-sealed and hardy. It's not perfect of course, with a narrow-ish maximum aperture and a few sharpness issues (all but unavoidable with a lens of this type), but it's a hugely impressive achievement of optical engineering and one that any Micro Four Thirds user will get a great deal of value out of.

The same focal range as the previous lens – but its polar opposite in just about all other ways. This is a gorgeous, high-quality pro lens, at a pro price.

OM System is simply the rebadged name for Olympus, following the sale of the Olympus imaging division to OM Digital Solutions. The new owners have been refreshing the line with new cameras and lenses, while also retaining everything that made Olympus so popular among its hardcore fanbase. You don't need to worry about compatibility – everything OM System will work completely seamlessly with everything Olympus, and vice-versa.

Almost impossibly slim and portable, the Olympus M.Zuiko 14-42mm f/3.5-5.6 EZ is an ideal take-everywhere standard zoom for street shooting, travel and more.

A cosmetic refresh of one of the oldest lenses on the Olympus books, this gorgeous zoom is still one of the best. Its pocketable dimensions make it ideal for travel.

There are so many good M.Zuiko standard zoom lenses that we had to leave some out! That's not because we don't rate them, but because we wanted to offer a balance spread of favorite choices. So even though they're not listed below, we still want to mention the original retracting M.Zuiko 14-42mm f/3.5-5.6 II R kit lens (plasticky feel, but rather good), Olympus M.Zuiko 12-45mm f/4 Pro (a slightly smaller alternative to the 12-40mm F2.8), the incredible Olympus M.Zuiko 12-100mm f/4 IS Pro (with a big zoom range and its own stabilizer) and the M.Zuiko 14-150mm f/4‑5.6 II superzoom (yes, a superzoom, but optically better than 9 out of 10 examples of its type).

As well as making very compact and portable f/1.8 and f/2 primes, OM System makes a series of whopping f/1.2 Pro primes too, and this is one of the most useful. Its 45mm focal length equate to 90mm in full frame terms, so this makes a superb portrait lens for OM cameras. Now we need to come clean about the MFT format and point out that the smaller format means you don't get the shallow depth of field of a full frame lens with this aperture, or an APS-C camera – its closer in its effect to f/2.3 on APS-C and f/3.5 on full frame. Even so, at f/1.2 the depth of field is extremely shallow and it's easy to blur backgrounds in portraits – and this lens has been designed to produce super-smooth bokeh too. OM's f/1.2 primes are pretty hefty brutes, but they are optically superb.

Of course, the best Micro Four Thirds lenses all fit and work on MFT cameras from all manufacturers – thanks to the fact that it is an open mount, so anybody can develop optics (or indeed cameras) for it.

There are a few too many M.Zuiko lenses to cram into a single guide, and they cater for a multitude of purposes and user types, so we've split our guide into four sections:

Every professional photographer keeps a 70-200mm f/2.8 lens in their kitbag to combine telephoto capability with a constant f/2.8 maximum aperture and controllable background blur for everything from wildlife to wedding portraits. The M.Zuiko f/2.8 Pro is the OM System equivalent... except that it goes further. Its effective zoom range is actually 80-300mm, so it offers 50% more reach than a regular 70-200mm. (You might also want to check out what it would cost to get a 300mm f/2.8 lens for other formats.) Better still, the 40-150mm f/2.8 Pro works with Olympus / OM Systems' 1.4x and 2x teleconverters to offer the equivalent of a 112-420mm f/4 or a 160-600mm f/5.6. It's like not one lens, but three (potentially)!

The brand may have changed, but the quality, integrity and heritage of the M.Zuiko line remains. You can rest assured that these lenses are as great as they always were,

Equivalent to a nifty-fifty in full-frame terms, this is the quintessential walkabout lens, perfect for photographing a range of subjects and scenarios.

For people who don't know this lens, it would be easy to dismiss it as a cheap and cheerful – but inferior – alternative to a 'proper' standard zoom lens. But not so fast! Optically, this little lens is a lot better than you might expect, and while its 28-84mm zoom range and f/3.5-5.6 maximum aperture are about as ordinary as kit lenses get, its sheer size – or lack of it – makes it incredibly useful.

If you're a fan of ultra-wideangle photography then you're in luck, because OM System makes three rather good ultra-wide zooms and we've included them all. These lenses are great for travel, architecture, interiors and dramatic landscape shots.

While the crop factor of MFT format cameras boosts the telephoto abilities of lenses, it makes the design of ultra-wide optics more of a challenge. The M.Zuiko 7-14mm f/2.8 Pro is a remarkable wide zoom lens with a minimum focal length of just 7mm, delivering an astonishing 114-degree viewing angle, similar to using a 14mm lens on full-frame cameras. Like other lenses in the Pro line-up, it’s immaculately turned out, with fabulous build quality. Contrast and sharpness are outstanding, while color fringing and distortions are negligible. As with many ultra-wide lenses, however, the hood is built-in so there’s no filter attachment thread.

If you're looking for just one standard lens for your Olympus / OM System camera, this pro-spec zoom is the best buy. It covers an equivalent range of 24-80mm.

If you have old Olympus lenses from the film SLR days, you may be wondering if you can use them on new Olympus and OM System cameras in the digital realm. The short answer is yes, as long as you have an adapter – they won't mount natively to Micro Four Thirds, but there are a number of affordable and good-quality adapters available (Urth makes a good Olympus OM to MFT mount adapter). Just remember that you'll only be able to use manual focus.

While we're still finishing our lab tests of this lens, it's looking safe to say that it's shaping up to be one of the best macro lenses on the market for the MFT system.

Being one of the oldest and largest metal detector retailers in the world, and serving as many customers as we do means we get a lot of questions.

We also until recently had the M.Zuiko 60mm f/2.8 Macro on this list – unquestionably a fine lens, but one that has had to step aside in favour of the mighty M.Zuiko 90mm f/3.5 Macro (see below).

The M.Zuiko 100-400mm f/5.0-6.3 IS perfectly illustrates some of the key advantages of the Micro Four Thirds format. Namely a compact and light weight lens that offers an incredible amount of reach for its size. With a focal length equivalent to 800mm at the long end, the M.Zuiko 100-400mm f/5.0-6.3 IS is also compatible with the Olympus M.Zuiko Digital 2x Teleconverter MC-20 and 1.4x Teleconverter MC-14 – which means that you can extend the maximum focal length to an enormous 1600mm if you want or need to. The downside is it's not at its sharpest when shooting at its maximum focal length, while you can't expect an f/6.3 lens to achieve the same results as faster and more expensive optics. If you're prepared to make a few sacrifices though, this is a decent lens if you're looking for a portable lens that'll hit 800mm.

Metaldetectors

As mentioned, the camera brand is officially called OM System, but you'll find both names on this list. We've kept this list manageable as there are simply too many for it to be comprehensive, so have stuck to simply including the lenses that have impressed us most. There's a range of options here, including some outrageously cheap lenses, so you should definitely be able to find a great lens for your Olympus or OM System camera.

While it takes time to master, the images you can capture with this powerful macro lens are simply unreal. The OM System M.Zuiko 90mm f/3.5 Macro offers a maximum reproduction ratio of 2:1 – which in 35mm terms (due to the smaller MFT sensor) is equivalent to 4:1. So, as we put it in our review, you could capture an image of a 5mm insect and reproduce it at 20mm, which is actually wider than the 17.5mm MFT sensor. It's the first autofocus lens to offer this reproduction ratio (the others are all manual focus).
