OM SYSTEM Olympus M.Zuiko Digital ED 7-14mm F2.8 Pro Lens, for Micro Four Thirds Cameras

I'm in love with this lens. This is by far the widest lens I've ever owned, so getting introduced to the 7-14mm perspective has been pretty amazing for landscapes, the image quality is stellar, and the build quality is great.Pros:1 - First and foremost, IQ is great. I was a little bit worried about getting a zoom over a fixed UWA lens, but since this is the top of Olympus' lens lineup in that range I was hoping the quality would be great, and it delivered in spades.2 - Nice and small. It's still a pretty good size for a m4/3 lens, but compared to DSLR lenses it's tiny. The other day I walked about 4 miles with an E-M1/40-150/2.8 on one shoulder, and I carried this lens on my hip attached to an E-P5. The wide lens and compact camera were barely even noticeable.3 - Manual focus clutch is super convenient. Since m4/3 lenses don't normally come with an AF/MF switch, switching to MF through the menu system is usually a pain that involves taking your eye away from the viewfinder. With the clutch right there on the focus ring, it's easy to do without looking.4 - Weather sealing when paired with the E-M1 or E-M5 II. I've never needed this so far, but it's nice to know it's there.Cons:1 - If you're not used to wide lenses (as I wasn't), this may come as a surprise, but you can't fit a regular lens cap or filter on this. It comes with a big saucer-looking lens cap that snaps over top of the entire hood/front lens element combo, and because the front element is curved there's nowhere to fit a filter.2 - I'm not sure if this is just my lens, but the manual focus clutch action seems a little bit flimsy, mechanically speaking. Every now and then I'll go to slide it back, but only one side of the ring will snap back and I'll have to cajole the other side over. It's a very minor issue, but occasionally annoying.On the whole, I'm very glad to have this in my bag.

I purchased this for my OM-5. So far it performs very well, even wide open. It balances very well on my OM-5.The fact that it's weather resistant is a major plus for me. My plan is to use it outdoors.Overall I'm happy with this lens.

Excellent, versatile lens. Great quality but note that standard filters will not fit

I've been looking for an amazing super wide lens to do gimbal stabilizer video work with. I have a Zhiyun Weebill Lab that can take some decent weight but is a bit limited in balancing space for front heavy camera setups. My go-to for Cinema EOS and adapted GH cameras has been my Tokina 11-20mm for APSC. With a speedbooster on the GH5, that lens is way too heavy. So I tested out three super wide native MFT mount lenses to replace it for gimbal work, with the Tokina as a baseline to compare all.Overall, it's hard to beat the tokina but the Olympus came very close in terms of functionality. Where it falters is weight, zoom ring stiffness and front filter adaptability. The optics are bar non the best of the super wide MFT zooms I tested. However this is the heaviest of them all, making the benefits over the Tokina marginal, but just enough to avoid needing counter weights.Also this lens is a pain to shoot in bright conditions with if you don't want to crank your shutter speed. You'll need to get a filter adapter, since the front element bulges out too much for standard threaded filters. This lens is great for indoor and night time shooting with the GH5S but just doesn't quite cut it for outdoor gimbal work since the goal is to avoid adding more stuff to the front to counter balance.And lastly, the zoom ring. If turning it while it's on a gimbal can make the camera roll 90 degrees to the side, it's way too tight for running and gunning gimbal work. You can throw off your horizon calibration easily with that. To adjust zoom without pushing the roll axis around, you'll need to set down your gimbal and then hold the camera body while turning the zoom ring. Not a great solution either way.So I ended up returning the lens with a heavy heart. I wanted it to work, but in the end it was more cost-efficient to just add counterweights and run with the adapted Tokina 11-20. If 2 out of the 3 above issues weren't there, then this would have been a keeper.

I have had 24 hours with the lens and LOVE it. I wasn't sure it would be fast enough. Dogs move fast.These three photos are 14mm, 8mm and 7mm. My dog was sitting on front of me as I was petting her and you do get the distortion but that's why I got it - I like the exaggerated way her features look. I know that on a dog with a snoot this will probably extend their snoot more.I currently have the 12mm prime, 15mm prime and 25mm PRO prime as well as the 45 mm prime and I can see myself using this lens a lot.It's a heavy lens. But I have the OMD M1 Mark II and so it's ok on this body.No regrets purchasing it. Took these photos in lower light and adjusted in lightroom I like the film look.

I suspect that anyone who is interested in buying this lens has read most of the reviews from places like DPReview. They praise the lens providing the sun is kept out of the picture (i.e., lens flare is a problem with this and essentially all fast super wide angle lenses). I have used the lens to take a few hundred pictures and concur with their findings, have not had problems with lens flare and think that the lens is terrific for an f2.8 super wide angle lens. In using the lens, I have observed that the lens does not seem as large and heavy as many have made out to be. It is about 40% smaller and lighter than an equivalent Canon or Nikon lens and balances well on both my E-M1 and E-M5 mark II. Taking pictures with a super wide angle lens is always a challenge because of the perspective. The Olympus OM-D bodies offer keystone control (i.e., perspective control) which makes taking pictures with this lens much easier. I have set the lens function button on my lens to keystone control and find that it makes the lens a joy to use.
