[0.05 lb] As an architectural photographer I am always looking for better wide angle optics. My business is to make client's buildings look great. Prior to purchasing this lens I rented one and shot it side by side with my Nikon 28 1.8, mirror up and electronic front curtain on the D810. The Otus far exceeded the Nikon in every respect. The only time they came even close was at infinity and f8, but even there the edges of the Zeiss were better. What has amazed me however are the many additional subject areas that I find myself shooting with it. I use it all the time when the magazine I shoot for needs a two page spread portrait. The ability to selectively focus a landscape area and let the background go soft is a real plus in terms of creativity. In short I could not be happier with the product.

[0.5 oz / 14.2 g] This is a superb work of art lens that has remarkable quality written all over it. The pictures are sharp and the resolution is as well. The color rendition is very accurate. There is slight distortion but easily corrected. There is a bit of chromatic aberration but also easily corrected. This lens performs as well as one can expect. It is probably best at ASA 64 and raw. It requires attention to detail to get its maximum yield. I am sure that a pro that has a particular use for this lens will be delighted with the results, but it is a LOT of lens for the skilled amateur and the hefty price makes you have to think about its role in your photography. I have owned it twice and just could not justify it despite it being the finest lens I owned. I own the Otus 55, the Otus 85 and the Milvus 135 all of which are sensational. The Otus 28 slightly lacks the snap of the others, but with after processing can yield some smashing photos. If I had unlimited resources, I would own it for the occasional app I could find for a lens of this caliber.

[0.05 lb] I got my first Zeiss, the Mulvis 15/2.8 last week. I was extremely impressed with that lens. Although manual focus, it has since kept the Sigma 12-24 and Nikon 16-35 in the bag. And I sent an Irix 15/2.4 Blackstone (a very nice lens actually) back. That initial experience gave me the confidence to order the Otus 28/1.4 and 55/1.4. I have not had full manual lenses since my Canon and Nikon film SLRS and my Mamiya and Rollei MF cameras. TBH, I wasn't sure if my decades-older eyes would be up to the task. Well, I am still not sure about that part, but this lens and the 810A are superb together. P, A, and S modes work flawlessly. I took it out today for a few dozen shots during early afternoon. Light was bright and a bit flat, uninteresting to say the least. But this lens is just extraordinary. Color richness and fidelity, the almost-3D effect of DOF, corner-to-corner sharpness, lack of distortion, resolution, all amazing. I have Sigma 35/1.4 and 24/1.4 Art lenses that I picked up primarily for astrophotography. This lens takes their place, as well as the Nikon 24-70/2.8, and every other lens that covers this range. Yes, it's big and heavy; this is not a kit for speed pack ascents. But I will haul these lenses around the world in the next couple of months, because once you have seen what they deliver, there is no going back.

[0.5 oz / 14.2 g] Big. Heavy. Bulbous. 1/3 stop clicks. Separate hood.

Oh, and optically flawless. Performance-wise, this lens is without compromise. If thats you, this is it. ZEISS recommends the 11604 or 11606 6-bit coding on digital M bodies, by the way!

[0.5 oz / 14.2 g] I purchased this lens with the idea of minimizing post production work on my photographs. I spent hours of research and found that the expert consensus was that the Zeiss Otus 28mm f/1.4 ZF.2 lens is possibly one of the finest to date. Since I have purchased it, I have used it on my Nikon D 850 extensively. My experience has been that It does require attention to detail in shooting, but it has never ceased to amaze me in its sharpness and color rendering. This is my second purchase of a new Zeiss lens. I'm extremely pleased with this lens.

[0.05 lb] This is a beautiful lens. I also have the Milvus 25mm f/1.4 ZE. The 25mm is lighter, and probably a little sharper on the edge, but the Otus 28mm delivers much more inspiring color, like the Otus 50mm f/1.4.

It feels harder to focus than the 25mm, probably due to its weight and size.

[0.05 lb] Made the plunge with this lens and I have no regrets. It's mind-boggling what it can do, from macro style shots to portraits to landscapes and astro-photography. Combine this lens with a Canon and you have a fine piece of heavy photographic weaponry on your hands.I like the fact that it's heavy, but it actually makes my 5D Mark IV look tiny, so I think it will be better to pair this with a 1DX II eventually. A couple of shots below, one out of the box and another up in the Himalayas, shot at F2.5, 4000ISO, 15 seconds. Still learning how to use this thing, but off to a good start and I'm seeing many years of enjoyment yet to come with this lens. Unfortunately I can't upload these photos because BH site keeps timing out on me, but

[0.05 lb] This is my 3rd Zeiss, 2nd Otus lens (have the 85mm Otus, 135mm APO Sonnar). I have been converting from my Nikon primes to Zeiss over the past two years because of the color quality, sharpness, and amazing build. I ordered the 28mm Otus yesterday, received it today, and took the attached image a couple hours later. Handheld, absolutely no post production done - NEF to JPEG image from a D4s in the weed patch behind my Minnesota cabin. I am excited to see what this lens can do, given the out of the box quality already seen.

[0.05 lb] I own the Zeiss 21, Zeiss milvus 25,35f1.4,85,135. Rented the Otus 28. My 21 has made some Sharp, contrast remarkable images images with my 5d Mkii, and mkiii. Shot it side by side w otus 28 at Palo Duro Canyon and Rocky Mountain National Park. Completely blew the 21 away on sharpness and especially contrast and depth of color at distance. Now have 5d milvus. The 25 blows away the 21 and sharpness near Otus. Both very even sharpness to corners at f8. Contrast not directly compared.Otus has a more adjustment to focus. The milvus has extremely small movement to be OOF. Otus more resistance like 21 vs milvus with less resistance. I greatly prefer the resistance of Otus and classic. Weatherproofing very important, my 21 has water damage!!! I prefer the old classic style vs Itus and Milvus. Otus at f1.4 is gorgeous. I think if I had to do it over I would go with the Otus for quality, but most of my scenes need 24-25.

[0.5 oz / 14.2 g] I got this fat boy to complete the trinity and knew what I was getting myself into. Manual focus and complete picture heaven. I'm extremely happy with the D800e (or D810 for that matter) and the otus combo. Can wait to use this lense on the future 50mp+ sensor to be released by Nikon. Now, for some nit picking: (1) Extremely big, wide girth. (2) Lense hood is made of slightly thinner metal than its brothers. (3) Be prepared to shell out ($+) for some quality 95mm filters. I 'had' to get the Zeiss UV filter as well as the circular polarizer for mine. The Lee adaptor for the 150mm filter set would be next on the shopping list. (4) Slight barrel distortion (which is easily corrected) but still left me somewhat disappointed in this regard. (5) Not weather sealed (6) Price. Closing comment: I don't know which focal length the otus line will venture into next. Personally I don't think it would be practical to make the otus with an even wider focal length (with the same f-stop), as it'll be physically too big and fat to mount on a camera and carry around on a shoot.
