Product Description

The M.Zuiko Digital ED 12-40mm F2.8 is the first lens in Olympus's 'PRO' lens line for Micro Four Thirds, and designed to match the top-end OM-D E-M1. It offers a 24-80mm equivalent range, and is dust-, splash- and freeze-proof. It uses a focus clutch design similar to the 12mm F2 and 17mm F2.8 primes, so pulling the focus ring back towards the camera engages manual focus mode and reveals a distance scale. The lens also has a L.Fn button, whose function can be assigned from the camera.

    My favorite lens ever

    This doesn't mean it's the 'best' lens ever. It's just my favorite because it provides me exactly what I want with the E-M1:  an excellent walk-around lens that allows me to take this camera into virtually ANY situation, and get GREAT pictures.  And that's why I invested in M43 in the first place.   I have other lens/camera combinations for other situations:  for unobtrusiveness, the Olympus E-PL5 with Panasonic 20mm f/1.7 is great and, in my opinion, a far better choice than the current hot ...

    Pro: Is takes very sharp pictures. Great image quality. It has a very nice zoom range. Change to manual focusing by sliding focus ring. Programable function button. It feels very solid. It's weather sealed Con: No syncronisation between the manual focusing ring and the focusing system inside the camera. Putting the focus ring on infinity don't´make the camera focusing on infinity automatically. (And not having focus peeking on a E-M5 dosn't make that better - will we ever have a software ...

    Olympus M.Zuiko Digital ED 12-40mm 1:2.8 PRO Lens - no hesitation needed.

    I bought the 12-40/2.8 with the EM-1 I have a swag of MFT Zuikos that carried over from the EM-5 to my EM-1 and this lens is very satisfying in every respect. Smooth, robust and SEALED. It comes with a hood and a pinch lens cap that does NOT fall off when you push on its edge as many others do. There's a metal ring protecting the pinch buttons and that super mechanical focus ring for zone focus devotees. Nice touch. I note that the 12-40 costs the same as the "full marketing frame" 55/1.8 ...

    So sharp, you'll cut yourself!

    Having used L series lenses for several years, I was a bit apprehensive on moving to M43 lenses but this little beauty has allayed my apprehension - this lens is on a par with my 24-105L but a full one stop faster but absolutely pin sharp even wide open. I was astounded by the results.

QUESTION

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

That lens works with any M43 camera body - and ensures a WR seal with the E-M1 or E-M5. The M5 has a pretty good track record for sealing but the M1 takes it up another notch. At a price of course and increase in size & weight. Good reviews on both at ming thein's web site: E-M5 review E-M1 review Great picture too: Quote: 10 minutes under a hot shower while powered on, sitting in about 1cm of standing water. All whilst intermittently shooting a frame or two, and no ill effects whatsoever afterwards. Impressive, to say the least. Continue Reading

Very funny, :-D I have one. It really is quite good value as a camera that is better than nothing in the pouring wet. Good fun, especially if you have kids or a totally inept and clumsy partner who throws things around without a care in the world. It has its place, but obviously not with the OP. Not unless he has one of the above and gets it as a third or fourth camera. I bought mine on the hop en-route to a festival where heavy rain was forecast. It turned out that it was sunny all three days and it wasn't used. It has taken about 50 images in three months and they are OK. Only OK by today's standards. Continue Reading

QUESTION

Olympus 11-22mm vs 14-40mm, Wide comparison request.

Hello, I'm a former Olympus user from way back, I started with the Original E-1. Since then I've been using a Nikon D700 for photos, and a GH2 for video. Having started with Olympus, I have a variety of regular 43 lenses I use with the GH2 via an adapter. I'm considering selling all of my current gear and using an E-M1 / 12-40mm combo. If the 12-40mm is as good or better than the 11-22mm, I'll put the 11-22mm up for trade or sell. **** My question or request is, I'd like to see what the difference is visually between the 11-22mm and 12-40mm on the wide end of each. I know it's probably a marginal difference in FOV, but I also wanted to compare distortion, color and sharpness. So if there are any willing participants who own both lenses, I would love to see a similar snap using each lens, 12mm vs 12mm would be fine. Although I'd like to see 11 vs 12 also just for comparison. Also if anyone has experience with both from actual field use, I'd like to hear your incite. Thanks in advance, ...

Good morning Travis.s I have both lenses, and have been doing a few wide comparison tests, because like you, I am still thinking which is the best choice. So far, I found that the angle of view with the lens on 12mm, is not exactly the same. A small advantage to the 11-22 (a bit wider). Sharpness and colour rendition are also quite different. I expect, between today October 4, and tomorrow to be able to post a few shots for comparison. Antonio GM Continue Reading

I also have both, I'll try and take a couple of untouched pics to compare them. I have to say that although I really love the 11-22, the convenience and general usability of the 12-40 makes it my go to choice for most things. In certain lighting conditions or perhaps if I were taking architectural photos I would use the 11-22 but mostly because I already have it, I probably wouldn't spring for it if I only had the 12-40. Having said that I've only had the 12-40 a short time so I haven't done any direct comparisons so this should be enlightening for me as well. Continue Reading
