Olympus M.Zuiko Digital ED 75mm F1.8 Preview

May 2012 | By Richard Butler and Andy Westlake

Preview based on a pre-production M.ZUIKO DIGITAL ED 75mm f1.8

With the new breed of mirrorless interchangeable lens cameras becoming ever-more popular, manufacturers face a development dilemma. It's not enough to simply churn out camera bodies; to convince potential buyers you have an attractive system, it's essential to provide a decent range of lenses too. But lens systems are hard to establish; concentrate your design resources on affordable lenses for enthusiasts and you risk your system not appealing to the high-end users who are likesly to buy multiple lenses. Focus instead on high-end exotica, and you risk making the step up from the kit-zoom look too daunting (and expensive) for the majority of users.

Perhaps because there are two manufacturers involved, the Micro Four Thirds lens range has balanced the needs of these two audiences well - there are a handful of sub-$400 lenses for enthusiasts, with alternatives such as the recently-announced Panasonic Lumix Vario G 12-35mm F2.8 ASPH OIS and the Leica-branded Summilux DG 25mm F1.4 for the higher-end user. Now, as a counterpart to Olympus's comparatively affordable M.Zuiko Digital 45mm F1.8 portrait lens, comes its more lofty 75mm F1.8.

The 45mm F1.8 is a lovely lens precisely because it offers great image quality while offering an attractive balance of size, price and weight. However, its mainly plastic construction makes it clear that there are trade-offs being made. By contrast, the 75mm features very solid-feeling all-metal construction and those rarely-inexpensive words 'Made in Japan' etched into the body. Sure enough the 75mm is expected to sell for more than twice the price of the 45mm.

Olympus describes the 75mm as a 'high grade portrait lens.' With its 150mm-equivalent field of view it's a little bit longer than the traditional 85-135mm range, that was classically used for portraiture on 35mm cameras. Its minimum focusing distance of 0.84m means you can get pretty close to your subject, however the long effective focal length limits how close you can sensibly work with people (because your narrow field-of-view gives quite a tight crop when working close to your subject).

The F1.8 maximum aperture provides decent control over depth of field, too, offering the ability to blur-away distracting backgrounds and focus attention on your subject. In this respect it behaves much like a 100mm F2.4 lens would on an APS-C camera, or a 150mm F3.5 lens on full frame. This makes it an attractive proposition for its primary purpose of photographing people.

The lens needn't just be used for portraiture, though. Olympus suggests it will also be useful for stage, studio and indoor sports work, and we see little reason to disagree with this. A 150mm-equivalent lens is still a useful thing to have in many circumstances, especially if it's as portable as the Olympus.

Near Leica quality without the Leica price! ;)


lots of nice glass in the lens.


How do you know?


• 3 Extra-low dispersion glass elements
• 2 High Refractive Index glass elements

I just don't know why you'd put such a good lens on such a low quality body/sensor. In my humble opinion, M4/3 just doesn't have the resolving power needed to really make this work. Is it sexy, yes! Will the shots, compared to other M4/3 lenses look fantastic - yes. But it's still M4/3 which is only slightly better than higher quality P&S compacts.


It should be able to go toe to toe with the best APC cameras. D7000, Nex 7, K5, 7D and so on. You need to understand the physics on why u4/3 sensor is the "perfect" size. The older sensors were bad but it did not stop people from taking beautiful pictures. This lens will serve the current and future gen u4/3 cameras well. As soon as I get a silver E-M5, I will put one of these on order. I plan on using it for wedding along with the D800.

@Norm - Waterloo: maybe you should read the review of the E-M5 before making misinformed assumptions like m4/3 "is only slightly better than higher quality P&S compacts".

Yes, @Norm, I have one of those "higher quality P&S compacts" - the Olympus XZ-1. While it's a great camera, there's a huge gap between it and my K-5. There's no way the XZ-1 could approach the image quality of the current u4/3s cameras, especially the E-M5. In fact, it can't even reach the narrow FOV of this lens at all - it can only go to 24mm at f/2.5 (equiv. to FOV of 112mm on 135, or approx. equiv. to 55mm @ f/5.8 on u4/3!).


@Norm The fact you have inferior sensor doesn't mean you have o make bad lenses. Even if the have crappy sensors in the past (for some people), Olympus still made very high quality lenses that outresolve their sensors. The difference is telling by mounting a HG lens on E-5 when compared to past models. And this can be done because the lens quality is so good.


Although it is a 75mm lens, it is not a portrait lens. It would be if the sensor was full size but it's not. This lens is a medium long telephoto, portraits with it will look a bit squashed.

Oh, c'mon guys, leave Norm alone, he's only out for the weekend.....
