Ordered This Lens from WEX at 3.00pm and it arrived the Next Day at 11.30am. Amazing service. The Lens is unbelievably sharp at all f stops including f2.8. THE only downside I can find is being unable to fit my Lee filters to this. But I am working on a solution at the moment.

The Olympus M.Zuiko ED 7-14mm f2.8 PRO ($1,299.99) is one of a pair of ultra-wide zooms available for the Micro Four Thirds camera system—the other being the Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. ($899.99). The Olympus lens is more expensive, but captures twice the light at its widest aperture, and is sealed against dust and moisture. It's an excellent performer, especially when you consider its extremely wide field of view and zoom design, and earns Editors' Choice honors. DesignLike the other lenses in Olympus' top-end PRO series, the 7-14mm ($1,299.00 at Amazon)  makes no compromises in build quality. It features a metal barrel and is sealed against dust and moisture, pairing well with a sealed body like the OM-D E-M1 ($999.00 at Amazon) . The lens measures 4.2 by 3.1 inches (HD) and weighs 1.2 pounds. That's a bit heavy for a Micro Four Thirds lens, but it balances fine on the E-M1, which has a deeper handgrip than many other mirrorless models. The bulbous front element ...

I was really excited when Olympus announced this lens. And what to say - it's really a good lens! It's sharp and the close focus distance is really nice on an ultra wide angle zoom. Build quality is (as with all pros) really good.

"This lens has magnificent scope and the glass is absolutely tack sharp. The continuous f2.8 allows for brilliant colour and contrast even in low light conditions. By utilizing the level gauge in my E-M5 mk II viewfinder there is little to no noticeable distortion at all.

An outstanding, one-of-a-kind lens. It is almost always in my bag, and if I can only take one lens, this is generally it.

114° angle of view at ?2.8 is simply incredible! When you take a picture on Wednesday, you have to be careful not to get Monday and Friday in the picture! Seriously, mind those feet and fingers; they end up in a lot of shots! Shooting movies with this, using Olympus IBIS, is a real experience.

I could wish for the ability to use filters; I could wish that the flare situation was better; I could wish it was smaller; lighter; and cheaper; but really; any lens in this category is going to be similar in these respects

Searching for imagery with these lenses starts off slow composition-wise and sneaks up with a bang right up to your eyeballs. This is ONE incredible piece of glass. Finding compositions with this is astounding once you find your groove and mood.

This is an amazing lens. My experience is in-tune with the reviews written here and elsewhere, it is absolutely beautiful. I purchased right before a trip where I would be in numerous cathedrals and wanted to be able to capture a very wide (or tall, in portrait) field of view, in low light.

I bought the M1 Mark ii and 7-14 pro lens as a kit. The image quality from this lens is amazing so I have now ordered 2 other images form the Pro line up to complete my kit.

Excellent lens, happy that I bought it

Theres not many native, Ultra wide angle autofocus lenses for mFT, and my choice was between the Olympus 7-14mm f2.8 PRO or the Panasonic 7-14mm f/4.0. The Olympus offers an extra stop, better build quality, for not much more money.
