The other day I was sitting at my desk just idly surfing the net when a courier van pulls up and leaves a small box. Once unwrapped it revealed an even smaller box containing the Olympus m.Zuiko Digital 25mm f1.8 lens. Now for a long time I’ve always believed that every photographer should own a fastish standard lens. In fact I also believe that if should ever find yourself in the photographic doldrums then just committing to use a standard lens for a period of 12 months will see your photography improve no end. I had one for my OM film system (and still have and use it) and I have one for my Canon EOS digital kit, but a little while back I had a dalliance with film range finder cameras and I eschewed the fast 50mm in favour of a pancake 35mm moderate wide-angle. In fact I was so smitten with the focal length that when I adopted the m4/3 system the Olympus 17mm f2.8 pancake was a must have, and if I look through my Lightroom catalogue over half the picture I’ve taken with my Pen and OMD have been with that lens. So now I’m in possession of a fast standard again.

NO OBVIOUS LENS DISTORTION.​

My initial impressions are that although it has a plastic body it is well made, although not as well made as say the 60mm f2.8 macro. It continues with the clean modern lines that Olympus adopted with the launch of the EM-5 and it feels well-balanced on both my EP-2 and EM-10. The other small thing that makes feel very positive about the lens is that Olympus have finally stopped being tight and are including lens hoods. The hood is hard plastic and bayonets securely on to the lens after the front cosmetic rim of the lens has been removed. Nice – a good lens should have a lens hood to get the best out of it. After a couple of days of shooting stills out and about I found that the focal length took a little adjusting to, it is a bit narrow for my tastes, but I quickly adapted and started looking for subjects that would play into its strengths.

So optically how did it fare? Very well. There is no distortion worth talking about and although shooting wide open there is some slight chromatic aberration but this disappears very quickly and by f4 it is gone. Sharpness is good with the centre of the lens performing very well wide open with some softening towards the corners again things improve quickly as you stop down, but get down past f11 and things start to soften up again as diffraction rears its ugly head. Diffraction isn’t a fault of the lens it is a problem with the size of the sensor, and all sensor and film sizes suffer from it. The lens isn’t what I would call “clinically” sharp in the way a lot of modern lenses are, it renders nicely and has a nice fall off from sharp edges to the out of focus areas. I’m not by any means a bokeh slut but this lens does render out of focus specular highlights in a very pleasing way. It made me want to go out and look for images that would give me those velvety smooth transitions.

BEACHSIDE BULLY RUN. THE AUTOFOCUS IS QUICK AND ACCURATE AND WAS ABLE TO TRACK MY DOG RUNNING ERRATICALLY ON THE BEACH.​

The lens focuses insanely quickly on the EM-10, which is as it should be on the latest generation of m4/3 cameras and is no slouch on my first generation EP-2. The worrier of DPReview now obsess over centring and on the micro four thirds forum the hysteria regarding the Olympus 25mm is something to behold. A few people there are expecting lens perfection from this lens and unfortunately no lens is perfect. Does the lens suffer excessively from being de-centred – well according my exhaustive testing of just one sample lens the answer is no. The lens is well within acceptable and I have seen much worse on lenses that cost ten times the amount this one does. My advice is that if you spend all day shooting pictures of brick walls and sheets of newspaper right way up and upside down then blow the resulting shots up to 3 or 400 % and then worry continually that you have a bad copy, or your rate of return rate of “faulty” products is so high that the customer service people know who is on the line just from the sound of your voice then you need a new hobby, therapy or both. Life is short, hobbies are supposed to bring enjoyment and fulfilment not create endless gear angst.

ON LOCATION FILMING AT THE BELLERIVE YACHT CLUB WITH THE OLYMPUS EM-10 AND 25MM F1.8 LENS.​

For video the lens is a very good choice. I shot the video clip below to test the lens’ resistance to flare, how it coped with continuous focus in video, close focusing and bokeh rendition.


Now there are some lenses which are so good that people buy into the system just to have a copy of that lens. Is the Olympus 25mm one of those? The short answer is no, but that is a disservice to this lens. It is a very capable performer and I think it should be given serious consideration by anyone who is already invested in the micro four thirds system. I really must say I was pleasantly surprised at how well the 25mm performed. It’s not the fastest lens, it’s not the most expensive, nor is it the cheapest. There are other m4/3 lens that are optically superlative and there are those whose performance is less than stellar to put it mildly. The Olympus m.Zuiko Digital 25mm f1.8 lens is a “Goldilocks” lens – just right.

That has really made my day, just superb little pun, cheers. I love my 25 its the most used prime on my cameras and I find nothing to grumble about it.

I completely agree about a fast normal lens improving one's photography. I bought the PL 25/1.4 almost two years ago and will never part with it. The 25/1.8 appears to be a lens that would instill the same sentiment.

Thanks for the review. I really don't "need" any more lenses, but if I did buy another, it'd be between this and the PL25. I liked the comment about needing a new hobby too!

#1 - you have some great shots there and a wonderful testing of the lens.
#2 - don't know if I could go an entire year with just a single focal length, but I do agree that it is a good way to improve your photographic "eye".
#3 - Also agree about the fast prime - though my current fast prime is the Olympus 17mm/1.8 even though back in my film days my favorite was a 50mm/1.4. Just feel that for walking around with a single focal length - do still do it, but not for 12 months - for me the 50mm equivalent was a bit too limiting, hence the 34mm equivalence of the 17mm/1.8. But after looking at your examples, I just might be tempted to pick up the 25mm.
Thanks for the post,
Steve

Sitting at my desk and reading your post while eating lunch, I found myself nodding in agreement with much of what you said. This was especially true when it came to your comments about testing lenses and how sticking with one focal length for an extended time period can help sharpen your eye.

I spent a good portion of the 1980's and 1990's where my go-to systems were a Hasselblad 500/CM or Rolleiflex 2.8 E. Both had 80 mm Planar lenses and, in the case of the Hassy, I could never afford additional Zeiss optics when I was at that age. So I sold the Hassy and bought the fixed lens Rollei. Looking back at those negatives, they are among my all time favorites. I've just started scanning them and have posted a few images in the "my full frame is film" thread. One reason the negatives are good is that I was always using a tripod and taking extreme care in composing my exposures. The other reason is that I was "stuck" with 80mm lenses for those years and was forced to adapt to my equipment's limitations. It's the main reason why I was always on the lookout for a used 25mm Oly or Panny lens to add to my current arsenal of optics. It just so happens that my first opportunity to buy was a nice PL 25mm f/1.4 but I would've been just as happy with the Oly 1.8. My EM-1 handles beautifully with the 25 and it'll be used heavily, even though I also have the 12-40 Pro.

Anyway, thanks for summing up many of my thoughts and for sharing some nicely composed images.

Before I had the O25, I was using the Sigma 30mm. I found myself often changing between the Sigma 30mm and the P14.

Since I got the O25, It seems I've never had to change to the P14. I find I a good thing which means that I'm very comfortable with the 25mm FL. :)

Great lens indeed!
