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 ...

E-M1 manual focus strangeness between lenses
Howdy. I'm new to the EM-1, and I've noticed something strange: I have peaking and magnification enabled for manual focus, in the menus. Using the 12-40mm lens, when I pull back on the focus ring, and engage MF, the camera zooms and peaks when turning the focus ring; as intended. However, when I do the same thing with the 17mm f1.8, magnification and peaking don't kick in when I pull the focus ring back to engage MF. Instead, I have to set buttons to force magnification and peaking. In the EVF, I can see that MF is engaged, but there's no magnification or peaking when adjusting focus. I'm wondering if this is known behavior with the 17mm, or if something may be wrong with my copy of the lens. The camera has been update to the latest firmware (v1.1).
Olympus 12-40 2.8 Question
I just purchased the Only 12-40 2.8 for my OM-D EM-1 and I have been extremely happy with it thus far. I have a question though. The zooming part of my lens has a bit of play to it. is this normal? I just want to make sure I don't have a defective unit. Thanks in advance.
I also received mine only yesterday but I cannot seem to see anything on the lens with what I would describe as play, the barrel ring for zoom is firm no movement that isn't conveyed to the mechanism, the snap focus ring is firm as well. I also have none of the grinding or tight movement noises as described by others? Continue Reading
The play occurs in the portion of the lens that extends during zooming. That portion of the lens has a bit of movement in directions perpendicular to the barrel. Not in and out from the camera, up, down, right and left and everything in between. It's not a lot of play, but it's there. Continue Reading
Olympus 12-40 f2.8 better than Nikon 18-200?
Hi guys, Currently I'm shooting with a D7000 and the Nikon 18-200. Mainly travel and family photo's. After upgrading from a D80 I'm not happy anymore with the 18-200 IQ, but I'm hesitant to buy an expensive and heavy 18-55 and 70-200. I'm interested in the lighter OMD E-M1 combined with the 12-40 and later on the 40-150. I would think that the better IQ of the 12-40 would compensate for the smaller sensor. Any thoughts/experiences? thanks!
To begin with the 18-200 and the Olympus 12-40 are lenses of two entirely different categories (and quality levels). 1. The 18-200 and 12-40 cannot be compared within the same category. The Zuiko should be compared more with the Nikkor 24-70 2.8 or the high-end Tamron regular zooms. Maybe you should also say is the Nikkor 18-200 better or worse than the Olympus 14-150 (equivalent to a 28-300), or the Panny 14-140 (equivalent to a 28-280). 2. The statement, "to offset the small sensor size," is really out of place here. The 4/3 sensors have reached a stage where they now compete solidly with APS-C sized sensors, and in some cases (depending on model) can surpass many an entry-level DSLR. So that consideration should now be laid to rest really. The Zuiko 12-40 is a high-end, professional level lens - with results often on line with fine prime lenses. Continue Reading
The 18–200mm has to cover a lotta ground and is thus optically compromised. It's not a bad lens—I used one for a couple years with a D300—but the 12–40mm is in a different league. A more apt comparison would be between the Nikon and a micro Four-Thirds 14–140mm. I have no experience with the latter. -Dave- Continue Reading
