Olympus M.Zuiko Digital ED 7-14mm F2.8 PRO Ultra Wide Angle Zoom Lens for Micro Four Thirds EZ-M0714PRO BLK

Absolutely superb lens. At 7-14mm it has the 35mm/full-frame equivalent view of a 14-28mm, so is a true super wide angle zoom lens. The sharpness, even fully open at f/2.8, is incredible although there is upon close inspection an unsurprising minor amount of corner vignetting at that setting. But it effectively vanishes at f/4 and is so even that it’s easy to correct in post on those very few images where it’s an issue.Being a Micro Four-Thirds lens it’s also far less bulky and heavy than my previous superwide zoom, the amazing Sigma 8-16mm (on my APS-C dSLR that had the equivalent 35mm/full-frame view of 12-24mm). The loss of 2mm equivalent at the widest setting doesn’t sound much but does make a genuine difference, although it’s a moot point as my only wider option on M4/3 is a fisheye lens, and I hate those.As the Sigma lacked the fast aperture and was noticeably quite soft until about f/8 I can accept the slightly less wide angle of view as a fair trade-off. In contrast this lens like the other two current PRO f/2.8 lenses appears to be sharpest fully open making the fast aperture fully usable and not just a marketing gimmick.Build quality on this lens is excellent: very solid on the bits which shouldn’t move and buttery smooth on the bits which should.Again, like all the Olympus PRO lenses this has a programmable function button on the lens barrel and I’ve chosen to assign that to Keystone Compensation which is amazingly good at correcting the converging verticals inherent in all wide angle lenses (done by software only: RAW files show no correction at all).The lens has noticeable barrel distortion on RAW images at the widest angle but it’s uniform and very easy to correct in your chosen digital darkroom (I use Affinity Photo). The camera itself has full software correction of the distortion which it applies to the JPEG files. Correcting the distortion optically would have been very difficult and would have added weight and cost, whilst reducing overall IQ so leaving it as is was a wise choice by Olympus. The distortion appears to my eyes to be almost absent on RAW files at the 14mm setting. I’m certainly no digital darkroom junkie so I am happy most of the time with the JPEG images anyway (I choose to use the lowest compression and low noise reduction settings).As the front lens element protrudes this lens carries no filter thread. But there are Third Party filter manufacturers who make adapters to carry their square-format filters such as the Lee system.As with all other Olympus PRO lenses, this lens is fully weather-sealed.

Absolutely stunning piece of kit, quality just oozes out of this product and the images are so crisp, excellent ultra wide angle lens, I would certainly recommend this product

If you love ultra wide angle lens, this one is hard to beat. I am a professional wedding photographer and I used to use the Canon 16-35 2.8 L II lens and this lens easily outperforms it, focusing speed, sharpness (corner to corner) and contrast is great. It has some heft to it but size wise it's much smaller then any full frame lenses. Distortion is well control and really great for landscape or any tight indoor photography!

I have had this lens for a couple of months now and highly recommend it, sure it is expensive and by far the most money I've ever spent on camera gear but the step up in image quality is unbelievable compared with the cheaper lenses. I have not been able to get out very far with it yet due to the Coronavirus but so far I have been really impressed with the results. I read a lot of reviews before I committed to it and there was so much talk about flare and soft areas, my advice is to ignore all that, if you are photographing test cards all day then it might be a deal breaker, in the real world it performs perfectly well. The build quality is superb with very tactile feedback from the controls, the impression is of a precision instrument which it undoubtedly is. It comes well packaged in a very smart looking box and has a nice soft case included. A point to note is at the 7mm end of the range the front element is more exposed and could be damaged if you are not paying attention, it's not a fault as it has to come out from the lens hood to get the angle of view at 7mm. In summary another fantastic Olympus lens.

You have to ask yourself how invested in the Micro 4/3 system you are before you buy this lens. It is a really good lens. It gives good bokeh, for an Olympus lens the effective 35mm f-stop number is 5.6 (because of how the m4/3 system works compared to the full frame format). It's sharp, and focusses quickly.Against this, it's heavy, and pricy. If you've a good variety of Olympus equipment, and want a good lens to act as a 14-28mm f5.6 lens, then this is the best lens you can get. If you see your future going a little further in photography, most professional photographers I've seen argue there are limitations to the M4/3 format that this lens can't overcome.
