Olympus M.Zuiko Digital ED 9-18 mm F4.0-5.6 Lens, Wide Angle Zoom, Suitable for All MFT Cameras (Olympus OM-D & PEN Models, Panasonic G-Series), Black

Product Information

Olympus and Panasonic bodies - as well as most raw converters - correct geometric distortion automatically. Even the live image seen on the LCD screen or through the electronic viewfinder - if your camera has one - is auto-corrected for distortion. In the case of the 9-18mm Olympus M.ZUIKO Digital lens, the correction is highly successful, with only a minimum of "residual" barrel distortion seen in photos taken at a focal length of 9mm. The Olympus 9-18 mm is equipped with multiple coatings on all lens elements and exhibits very little about radiation. Even a street lamp in a night scene did not ghosting on and a slight degree of over-radiation. In the same situation is much more expensive Panasonic 7-14 mm or ghosting,

Olympus Zuiko 9-18mm f/4-5.6 ED Interchangeable Lens Review

Its wide enough, though 7-14 was wide, insanely wide, this in my opinion is mostly what I needed, there were very few times (less thab 5%), when I missed the wider coverage. The lens' lightweight design coupled with In-Body Image Stabilization - available in the flagship E-3,Does the 8-25 not do this? The 7-14 is a huge moneymaker for me, I almost never use it at 7mm but I do shoot a ton of architecture, and resolving power using multi shot is the most important part of that to me. It actually has pronounced chromatic aberrations, but these are effectively removed in the raw processing. For me, it appears that at the longer end of the focal range it gets a bit soft, but I from 12mm on I use the 12-40mm anyway. So for me it is just a super-wide alternative that sits in a small corner of my bag in case that 12mm is not wide enough. And in this sense, the 7-14 could not be a replacement, despite the more useful focal range. But as always: That lens that you have at hand when you need it, is the best lens!

Olympus M.Zuiko 9-18mm f4-5.6 (Micro Four Thirds) Review: Olympus M.Zuiko 9-18mm f4-5.6 (Micro Four Thirds)

Especially at the smaller focal lengths, the corner sharpness remains behind the centre sharpness. This lens, like the Olympus 45 mm 1.8, is an inexpensive lens that offers first class optical performance: a very high resolution, low distortion and low vignetting. Chromatic aberration visible at 100% cropping, which you can easily correct afterwards, is the only disadvantage when you evaluate it's optical performance. Some raw converters - such as Raw Therapee - can show you the uncorrected image which, in the case of this particular lens, tends to have a lot more distortion to it, at least at the 9mm setting. It takes filter so add on a small UV filter (Hoya HD Pro UV is my choice) and you are safe with the glass. I lost the lens cap (at western wall), so UV filter is all I am having on it now. Actually its good in a way, I dont have to keep worrying about removing and placing cap, all the time now. This is the final part in the series reviewing the Olympus 7-14 and the 9-18. In Part 1 we reviewed the 9-18mm. In Part 2 we reviewed the 7-14. Now we look at these two lenses compared to each other. Is the (relatively) larger, faster, more expensive lens the better choice to the small, lightweight, lens? Let’s see. 7-14 vs 9-18 From Olympus lens literature) Olympus has applied its optical expertise to develop the Zuiko Digital 18-36mm equivalent (ED 9-18mm Four Thirds) f4.0-f5.6, a super-wide-angle zoom lens covering a wide focal length range. This compact ultra-wide-angle zoom lens can be used on any of the Olympus E-System digital single lens reflex (DSLR) camera bodies, and measures only 3 inches long and weighs a mere 9.88 ounces for greater portability.

Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Olympus 9-18 vs Panasonic 7-14 - Digital Photography Review Olympus 9-18 vs Panasonic 7-14 - Digital Photography Review

I used the M.Zuiko 9-18 with a polarizer filter attached most of the time, but in the few situations where I did not use it, my impression was that the lens renders colors slightly muted and a tad to the coolish side. Of course, this is all relative when you shoot raw files and tweak the colors during post-processing. In general, less saturated colors give more leeway for post-processing. Conclusions The lens barrel is almost entirely constructed from lightweight plastic, with the only metal part being the mount. Despite the lightweight construction, the build is more than acceptable, striking a good balance between keeping the weight down and durability. The fit and finish is good, although this is certainly not a professional grade optic. This last shot is what impresses me the most. Look at the corner of the 7-14mm!!! Not only does it have good definition…it does not have the smearing a lot of wide angles have in the extreme corner. For being a 7mm lens…this is pretty amazing. Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. In the M.ZUIKO Digital ED 9-18mm f/4-5.6, Olympus employed an iris diaphragm with rounded aperture blades for a pleasing bokeh, but it was only partially successful - as seen in the examples below.Olympus provides us with image stabilization which is built into the camera (“IBIS”). The Olympus IBIS is highly effective, as we have seen during testing of the Olympus 45 mm 1.8 and the Olympus OM-D E-M5. When we reached at longer focal lengths through the IBIS a profit of 4 stops. The lens comes with a standard Micro Four Thirds mount that is, thankfully, made of metal. Olympus does not claim any sort of weather resistance for this lens, and indeed you cannot see a rubber seal around the mount (note that no current Micro Four Thirds camera is weather sealed anyway). The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column.

Olympus 9-18: Please check the status of a lens - HELP! Olympus 9-18: Please check the status of a lens - HELP!

It’s not an exaggeration to say that all three of these lenses are extremely sharp, particularly in the center. The resolution of the 9-18mm falls off a little more toward the extreme edges and corners, but even there it’s a very strong performer. Somewhat surprisingly, the Panasonic 7-14mm shows more CA toward the midway point and edge of the frame, but it's sharper at the edges and corners than either Olympus lens.So this makes two such faults over how many hundreds of units sold....? Just a pity it's Nils and me.
