Product Description

The M.Zuiko Digital 25mm F1.8 is a small, fast, 'normal' prime for Micro Four Thirds cameras, that bears a distinct family resemblance to Olympus's much-loved 45mm F1.8. It offers an interesting alternative to the more-expensive Panasonic Leica Summilux DG 25mm F1.4, or the compact Panasonic Lumix G 20mm F1.7 II ASPH 'pancake'. It will be available in a choice of black or silver.

    Olympus 25mm f1.8 is a great lens

    I have had the Olympus 25mm f1.8 lens for a few days now, and I am very happy with it. Selected photos I have taken with the 25mm f1.8 are here (nothing special, just everyday scenes). My short review of the lens, based on a few days of usage: BUILD The lens has a plastic body with a metal lens mount, and feels solid. The focus-by-wire focus ring is about as wide as a finger and feels nicely damped. Olympus includes a bayonet style plastic lens hood with the 25mm f1.8. SHARPNESS The 25mm f1.8 ...

    I Love it!

    I own the 25 mm just two weeks now, but I'm already convinced! But I have to tell you that I'm not a professional photographer or image expert. Just before my trip to The Gambia I could manage it to get one silver version in my hands. Silver makes the better images, right? And it fits well and looks great on my PEN E-P5. The lens iis -in my opinion- extremely fast with focusing and I had not much shots out of focus. It was really a joy to have it on my camera. Razor sharp and although it ...

    Olympus M.Zuiko Digital 25mm F1.8 A MUST have lens

    Finally I've got my Zuiko m4/3 25mm f/1.8 lens, in Italy as usual  all Olympus and Zuiko products arrive a little bit later than all the other European countries. I owned already the m4/3 17mm f/1.8 and was very happy with it. I'm a street photographer and the 35 mm equivalent is the best lens for reportages. Now I'm owning the 25mm too equivalent to 50mm on 35mm slr and let me say that I'm getting addicted! I'm not a technical expert, I judge the quality of the lens only the image taken. By ...

Questions & Answers


Oly 25mm F1.8 / Oly 12-40?

Good afternoon all, Having got into Mft through a secondhand EP-3 to complement my wonderful E5, I fell in love with the primes. I have the Oly 45mm f1.8, a little marvel, and the 75mm F1.8, an amazing piece of kit, complete with the Pana 14 F2.5!  I have now taken the plunge and just bought an E-M1 c/w 12-40mm. I am still learning, but this camera is already delighting me, and confusing me, and giving me plenty to learn!  :-) My question:  I am really taken with the idea of supplementing my primes with the Oly 25mm F1.8. For those who have both  zoom and primes, do you find that you are not using the primes due to the quality of the 12-40?  I appreciate the size/weatherseal/wider aperture differences, just wonder about usability?  I hope that makes sense. Apologies in advance if this has already been asked.  My ability to search this forum needs to improve. Regards Paul

Hmm yes... depends on the amount of people and the room of course. However, I don't like how 12mm starts to distort faces, specially of people close to the border of the image. Nothing dramatic, but I kinda dislike that... that's the main reason why I prefer the 17mm or 25mm for people group shots :) People look more natural. Continue Reading

Only because it has yet to me mentioned, because you now have the E-M1 you can shoot the fast primes in sunlight without ND filters, which extends their usefulness. Like some of the others, I have both the 12-40 and 25, and find there are times for each. The 25 is much fun to use and my eye does seem to like the "standard" focal length for general shooting. Seems quite sharp, too. This shot, while at f:2.8, could also have been taken at 1.8 w/o blowing the highlights. DOFs become quite shallow, putting an emphasis on focus accuracy. The 25 @ 1/8000, f:2.8. And they throw in the hood! Cheers, Rick Continue Reading

The 25 1.8 is a terrific lens, very sharp, lightweight and great for street shooting and any low light situation. It works well indoors when you don't want or need to use flash and it is a take everywhere lens. Continue Reading

I'm in Singapore and everything is SOOOO much cheaper, what to buy?

Currently in Singapore 11 weeks into 30 week travels and have been waiting to get here to buy some new gear.  What I've found, and really, really want the Olympus 12-40 f2.8 PRO & Olympus 25 f1.8, which will cost me around £800 (12-40 on its own in UK costs £900).  To (partly) fund the new lenses I plan to sell my Olympus 12-50 and Pamasonic 14 f2.5. However, after a few questions in the shop (and with a massive grin on my face) I found out that if I buy the 12-40 as a kit on a new E-M5 or E-M1 the lens would be cheaper, obviously, but I would also save so much money on another body, dilemma! So, the question is, do I buy the two lenses and save myself about £500, or do I buy the E-M5 kit and 25mm and save around £600, or the E-M1 and 25mm and save £800? I'm not sure if I NEED another body, and I don't really have the money to warrant spending so much, if I buy one of the bodies I'll sell my E-PL3 and I have some other things I could sell, when I get home in 5 months that is. So is ...

I'm pretty conservative when it comes to money.  So spending money I can't really afford, to buy products I don't really need, just because I spot a 'deal', seems illogical to me. Now if I expected to make a profit selling stuff later that might be different.  But I bet when you factor in the import costs to your home country, the savings aren't as great as they seem right now, so even the expected profit from a quick resale might prove illusory. My advise is buy what you need and use the extra money you might have spent on gear for some sight seeing/photo trips and you might not have spent money on otherwise. Modern photo gear lasts 5 years, if we're lucky.  But our memories (and the photos we make) will last as long as we do! Continue Reading

I think you shld just go ahead and buy both lenses rather than buy another body with it. Continue Reading

Lenses are always the best investment. You're not saving money by buying a camera body you don't need, surely! So I would buy the lenses only. But, if you were to buy another body, I would reccomend the E-M1. You gain features you don't have (better EVF, PDAF, focus peaking, better grip) in a body that will better balance the 12-40/2.8. Don't underestimate the value of PDAF if you ever want to photograph wildlife or sport. And the E-M1 uses the same batteries as the E-M5. Do you use video at all? The E-M1 has a video teleconverter, that turns a 25/1.8 into a 100/1.8. It's an amazing feature to have for low light video of a performance. But, personally, I don't travel with a back-up body. And you already have one. And you can't sell your extras until you get home. So any extra money you spend now, is money you can't spend while travelling. If you are in Singapore for a while, there is an excellent local photography forum called Clubsnap. They will happily help you find the best deal, ... Continue Reading
