  • Huge heads up before you head out to shoot night skies - Please read!
Style: Nikon
This lens has done extremely well for me over the past couple of years. All the way until the last two major shoots in the Bisti Badlands and last night in Yosemite. None of my shots came out and I couldn't figure out what was wrong. At first I thought it was just that I hadn't accounted for the sensor size of the D850. But last night, my shots were blurry at my former settings on the D750 as well. So I figured it must be the lens. Upon closer inspection, the front element of the lens was LOOSE and halfway out of its threads! I had no idea that you could screw it completely out!! Why isn't it sealed? I honestly never noticed it was loose when cleaning and it was only as I began to really examine it to see what was wrong that I discovered that the front element turned easily. That means every time I cleaned that lens, the front element turned a little without me realizing it. At F8, my images were still surprisingly sharp. But when shooting the milky way at 2.8, the center was blurry and the sides were almost sharp. It was driving me nuts trying to figure out what had happened. So....watch that front element when cleaning because it may come loose and begin to turn on you! ... show more

  • So far, so good
Style: Nikon
But it hasn't been that far - just got the lens today and shot some quick test shots. The reason I'm writing this review (which I will update at another time with some specific remarks about the lens regarding quality, handling, etc.) is to clarify something that was making me crazy as I researched it. FYI, all of my tests were on a Nikon D750, but I see no reason this lens won't work on any of the Nikon's made in the past 5 years or so. This is a Nikon-compatible lens with an AE chip. It is strictly a manual focus lens (no auto-focus), and you can find lots of references to the fact that the AE chip will interface with your Nikon (as long as you're using in in A/M/S or P modes), and the viewfinder info bar will tell you when you're in focus as you turn the focus ring. You'll also be told that unless you set your aperture to F/22, you'll get an "EE" error. Ok, that's straightforward enough, and very true. :) Dig a little further, and you'll find references to the lens being recognized by the Nikon camera while in the A/M/S/P modes (also true), and the EXIF of the picture containing the lens information, along with other stuff, just like any other compatible lens (again, also true). Unfortunately... after that, you get a bunch of conflicting posts, reviews and information about controlling the aperture with the Nikon dial. Most tell you it doesn't do it at all, but changes the exposure based on the aperture setting you manually set on the lens. You may - if you're lucky - find one post that tells you it DOES set with the control dial. The truth is the latter - you DO control the aperture via the control dial when in A/S/M/P modes. :) So to sum it up - in A/S/M/P modes: 1) The CAMERA will tell you via the viewfinder when you're focused as you MANUALLY focus (no auto on this lens at all, which is fine given it's purpose) 2) The LENS will pass the proper EXIF data to the CAMERA (just like any other CPU-enabled lens) 3) You MUST set the aperture ring on F/22, or you WILL get a flashing EE error in your viewfinder 4) You CAN control the aperture via the front control dial All good news. :) The only thing I'm worried about with the lens so far is that there's no aperture lock on the lens. I have a Tokina 100m (Macro) lens which works exactly the same way (except it DOES have autofocus), and without the lock, I keep slipping the aperture ring out of position accidentally. That's probably not going to be a problem here, because the lens is so short that I'll likely keep my hand on the focus ring, unlike the Tokina which I grasp the barrel on to steady things up when shooting as a telephoto. So... so far, so good. I'll run some good tests in a few days, maybe do some focus testing, and see where this goes. :) ****************************** Update 3/8/2017 ****************************** This lens is EXCELLENT. Sharp, very sharp - easy to manage, and the images are precisely what they should be for a 12mm fish eye. I've been doing some image corrections with an Adobe-compatible plug-in, and I've gotten some very good results in terms of reducing the distortion while keeping the entire image in place... with little or no "smearing" at the edges and corners. (Imadio Hemi). Good purchase. Now all I need to do is go to some really wide areas and work this thing to the bone. :) ... show more

  • Learn to shoot by distance scale, but it's not 100% meh.
Style: Nikon
Caveat: I am a photographer- it has been my full-time job for most of my adult life. I bought this because I wanted an ultra wide to mess around with sometimes. The vast majority of what I do is portraiture, and this lens is not suited for that use. I'm trying to review it with those facts in mind- and that's why it's a 2-star, and not a 1-star review. Pros: it's cheap and seems relatively tough (there is a fair bit of metal in its construction). I like the hard plastic clip on front lens cover. The fisheye distortion can be cool too? I don't know. My kid says I need to be more positive about things. Cons: well, everything else. (Sorry, son.) I really wanted to like this lens, but it is pretty bad. Focus confirmation is a joke at the 12mm, 180-degree field-of-view, so plan to learn to shoot from the hip using the (roughly accurate) focus scale on top of the lens barrel. Like the focus confirmation, the 2.8 aperture doesn't seem to be truly 2.8. I do believe that's what's being reported to the camera, but on my d850 I have to overexpose by at least a full stop to get what I'd consider a normal exposure. The glass is contrasty and to be totally honest I didn't bother to pixel-peep for chromatic aberration, because it's visible without zooming in. On my copy, I've noticed that the entire right side of the image is soft (with no sharp points at all, no matter where the focus is set). On a tripod it's fine for long exposure night shots, but be prepared to suffer the one stop penalty when shooting, and don't angle it up or down much as there is visible focus drift (in a prime lens!) when it's set in a too-vertical orientation. I did try it for a little street photography, but to get a reasonable shutter speed I really had to bump the ISO. In summary, if you're thinking about this piece of glass, I wouldn't bother. There are plenty of places to pick up better quality used glass in the same ultra-wide range, for the same price or lower, without the frustrations this lens presents. ... show more

  • Great price, and amazing Lens!
Style: Nikon
A great fisheye lens, it is manual focus ONLY, but setting it right under infinity gets sharp, clean images every time you are shooting wide!
