Super Standard Zoom; Smooth and Compact
I have had this m-4/3 Pro 12-40 f/2.8 lens for four days now, and use it on an E-M1. This lens works great… focus is extremely fast, and gives really sharp results.
The zoom range covers everything from a super wide 12 mm to a short telephoto 40 mm (24 mm wide angle to 80 mm telephoto on a 35 mm system). The quality of this glass is amazing! My images have come out very sharp and crisp, with fine contrast. The colors produced are Rich and Saturated… True Olympus Quality.
Shooting in low light has produced very good results also, achieving excellent focus. The camera (E-M1) was set to ISO Auto, so it selected a high enough setting to allow a faster shutter speed to be used.
There is so much you can do with this lens. By itself, it would (and probably will) be a great choice for weddings. I have used the 11-22mm lens for weddings, and it works great; 11mm is great for groups after the service, and the 22mm length is excellent for head-and-shoulders of bride & groom, full length bride, etc. I use a longer lens for shots during the ceremony (50mm f/2.0 is a great choice). But now I think the 40mm range of the 12-40 will work for the same shots. Then I can use only one lens to do the whole job. For portraiture, everything applies as well. The fast f/2.8 aperture is perfect!
The lens is just a super “All Around Lens”, letting you shoot in so many situations. The fast f/2.8 allows you to get a great “out of focus” bokeh in your back-grounds.
The weight is 382 g, which is less than 480 g for my 11-22 (plus MMF-3 Adapter)… (even less than the 575 g for my 12-60mm)
Olympus I think came up with a remarkable feature on the lens shade (LH-66) for this lens. It has two latches on opposite sides of the shade, which click when the shade locks into place on the lens, and you have to press them to un-lock the shade. I like the design of the shade very much!
The 12-40mm Pro is a great lens. I like the range of my 12-60 better (or I am more used to that range), but the 12-40 range matches the lens range I used on my OM-1 in the film days. I shot a lot of images with an 85mm f/2.0 Zuiko (plus 24 f/2.0, 28 f/2.0 and 50 f/1.4) This lens covers all those primes
Also, they offer a FRF-D62 filter, to protect the front element… everyone should have a filter protecting the front element on ALL their lenses.
A costly lens in the Pro series, but I do not regret spending the money on it; it really is worth the investment. I can produce just about any image with this lens. It should be high on every one’s list of lenses to have, especially when using the OM-D cameras or the E-P5 etc.
Environmental wedding portrait lens
I was in love with my 12-60mm. This lens is in a different league all together. The constant f2.8 is insane. Used for our wedding photography and EM-1. Must have as part of your kit.
This lens (and the E-M1) has been my first foray into mirrors cameras, and my first step away from over a decade's use of Canon equipment.
To say I'm impressed is an understatement. The image quality, colour rendition and sharpness are fantastic. The focus is silent and lightning quick.
On top of all of this, the build quality and attention to detail are superb; this lens is so nice that it makes look for excuses to use it (as does the 40-150 PRO). I was initially very hesitant to move to Olympus: I had regarded them as a tier two manufacturer, and not in the same league as Canon and Nikon. Boy, was I wrong. I rate the build quality, finish and attention to detail over some of the Canon L lenses I own. The lens is beautifully machined. The focus ring has a nice smooth action in either position, and has a very satisfying 'click' when changing operation.
I really commend Olympus on their PRO series of products: lightweight, fantastic design and quality, and weatherproof. I have been searching for a system like this for years, and have always felt that I'd need to compromise. I have absolutely no complaints with this lineup and cannot wait for more products in the series to be released.
One of The Best Standard Zooms
Not going to bore you with what hasn't been already been said about how superlative this lens is, because it is. Sharp corner to corner throughout the entire zoom range, comparable to the primes. Color is accurate and well rendered, chromatic aberration and other such things are well controlled. The ability to focus closely really makes this lens apart from its competitor.
I will note that compared to some of the primes, the color saturation is a bit lower, needing a slight boost in post processing to correct.
I use this lens a lot, and enjoy it immensely. The only thing I would keep in mind is that it is neither compact, nor light for a m4/3 body. I the world of APS-C and FF bodies this lens is tiny and light, but relative to its own ecosystem, just be aware that this lens doesn't balance well on the more compact m4/3 bodies.
Simply the best lens I've ever owned! Olympus has made a great system even better by adding the Pro Series! Two words in my recommendation, "Buy It!" I can't wait for the other lenses in this series to be released in 2015.
