    This is not an everyday casual lens. I bought this lens, because I was looking for a way to capture better detail of the moon without spending a small fortune. I have also used this lens to take pictures of distant skylines. For my special purposes, it's an incredible value. It's light, simple, and rugged (mostly metal). I use it with a Vixen 37301 T Ring adapter and a Nikon D800.

    Shooting with this lens is a process. The slightest vibration will blur the image. Being ever so slightly off with the focus ring will also blur the image. You'll want to use a tripod, and a remote and/or delayed exposure/mirror-lock-up to reduce internal vibration. For focusing, you'll want to use your camera's display to digitally zoom in. The slightest turn of the focus ring can result in a blurry image. So, take a little time to get it just right by checking the display. Take several exposures. Check them before you move on.

    At its sharpest, the lens will probably be a bit softer than any of your other lenses, but this is easy to correct in Lightroom or Photoshop without getting that artificially sharpened look. Since a mirror lens does not produce chromatic aberration, the edges are cleaner and easier to sharpen.

    If you take the time to shoot with this lens correctly, you'll get results that compete with lenses that cost 65x more.

        Really liked the feel of this lens but I could NOT get a good focus. I use a VERY stable surveyor's tripod modified for the camera mount along with a remote shutter release. I tried, tried and tried to get a good focused picture, in different light from bright sunlight to full moon pics, but could NOT get a decent focus.
        Reading other reviews, I hope this is just the lens I received but thought it was worth sharing the experience.

          Comments about Rokinon 800mm f/8.0 Mirror T-Mount Lens (Tan):

          Many reviewers noting the extreme difficulty in focusing this lens. I agree. I set up a tripod, used a shutter release in live view mode on my D800E and was never able to get an image that was better than acceptable. If you imagine using this for wildlife, you got a long row to hoe. I believe that with practice you could get to where some, probably not most of your shots are keeps if your threshold is not too high.

          I found that shots of street signs always had a fringe around the letters not matter how carefully I tried to focus and refocus. I returned mine. I go with less magnification and use my Nikon 80-400 w/ TC-14E-II 1.4 teleconverter. The images similarly cropped to match the Rokinon were as good or better. And with the Nikon I get autofocus and better contrast.

          The construction of the lens is good. The only downside : the focus is a bit stiff and too sensitive.

          FOr the price, it takes great pictures of the moon.

          Comments about Rokinon 800mm f/8.0 Mirror T-Mount Lens (Tan):

          I rated this at four stars, mostly because of the good value. If I was rating based solely on the performance I have experienced, I'd rate it a 3.5.I am an amateur photographer who has taken a few classes, read up on things and practiced quite a bit. In the past couple of years, I've become very interested in photographing the moon. I have other lenses I've used to take photos of the moon, but it had become increasingly clear to me that perhaps an 800mm with a teleconverter (to equal 1600mm) would be a good option for me.Being an amateur and having limited resources to spend on my hobby, I opted to buy this lens and use a teleconverter I already own. Having only f/8.0 to work with is limiting, but I set up my tripod and adjusted the ISO and shutter speed until I found a good mix (ISO 200, shutter speed 1/250) and took some very good photos of the moon that my (also amateur) friends have admired.I've also used this lens at the zoo and botanical gardens without the teleconverter and it took very nice photos as well. I plan to try my luck at a state park with eagles next winter, and expect to have good results there as well.To summarize, for the money this is a lens that will give you very nice photos and I am very happy with my purchase.

          A decent lens for moon rise/set as well as [carefully] sun rise/set images. One shot of a sailboat passing in front of a huge setting sun makes the purchase worth it. Use it on an APS-C cam for even more magnification. 1200mm equliv. on my Nikon D90. Critical focus can be tricky, as a slight turn of the barrel makes a big difference. Cable release or exposure delay mode recommended to avoid blur from vibration. Contrast is low, but can be easily adjusted in post. Decent considering a pro 800mm carries a five digit price tag.

          Comments about Rokinon 800mm f/8.0 Mirror T-Mount Lens (Tan):

          This lens is manual focus and fixed aperture, and has the characteristic ring bokeh you get with mirror lenses. Note you will also need a lens adapter to fit this lens to your camera body. (T mount to Nikon or Canon mount)I bought this lens for those occasional times when I really need the extreme reach, and it is indeed extreme. I find myself having to back up with my feet to fill a subject in a frame. If you were at a baseball stadium and wanted the batter in view, you'd have to be sitting in the outfield bleachers. Framing is a big challenge.For wildlife photography, which is my primary purpose for getting this lens, there are a couple of gotchas. Finding your subject and tracking it with an 800mm lens is extremely challenging. The F/8 aperture means you need really good light, and the 800 length means you'll want a very fast shutter speed to avoid blur from hand shake. If you want to handhold this lens (which is tempting, because it is very lightweight) you will need a camera with great high ISO performance. But in all honesty, the sane way to use this lens is on a sturdy tripod. This lens is capable of sharp images, but attaining critical focus manually is very difficult.With all the "minuses", you may be wondering what are the pluses? Well the good news is for wildlife photography, at 800mm you can focus on wildlife without scaring them off. Which is a pretty huge plus. I plan to keep this lens for that very reason. I have pro level telephoto lenses that are far more capable and more expensive, but this is light and compact and great for "scouting" an nature area I might return to later. I'm not afraid to leave this lens in the car.I would "cautiously" recommend this to a friend, but only if they fully understood the limitations going in.

              I bought this lens for eclipses (solar/lunar), Moon on the horizon shots, and the transit of Venus. Price/ performance ratio is very good but there are two limitations to be aware of.First is balance. The Rokinon was chosen over the other similar mirror lenses because the specifications web page listed a "fixed-rotating" tripod collar. Since this feature couldn't be seen in the product pictures I called B&H to verify. The salesman asked what I thought a "fixed-rotating" tripod collar was (a way to mount the lens directly to a tripod) and then he assured me that the lens did have that feature. There is no way to mount the lens directly to a tripod. While not too much trouble to rig up a bracket for better balance (needed), it was even more disappointing to be assured that the lens could be mounted directly to a tripod.Second limitation involves focus. The internal threading is ten times too coarse for manual focus. Magnified "live view" was required to check focus, but even then it was nearly impossible to focus sharply because the internal focusing threads are too coarse. I found it necessary to rig up method of a fine focusing adjustment with a hose clamp, rubber band, and an 8-32 screw.

              Comments about 800mm f/8.0 Mirror T-Mount Lens (Tan):

              Is it sharp? Not terribly but 800mm is powerful, especially on an APS-C camera. I am not a wildlife shooter, I'm a landscape photographer, so I have no reason (and no funds) to invest in anything like this length of lens in a Canon L, for example which would be about 70X the price. This lens is about 70x lighter than a regular big lens would be as well. My main lenses ARE L lenses, but this is for the occasional long shot that crops up, like when wildlife just insists on being photogenic right in front of me or I want to pick out a detail. Images from this will be sent through the full battery of sharpening tools and printed in modest sizes. For that, it's perfect. This lens is f8, so some cameras may not auto-focus with it but the big thing to know is that it does NOT HAVE A DIAPHRAGM so there is no adjustment there. It's ALWAYS f/8, there is no other f stop. So exposure is controlled entirely by shutter speed and ISO. It also means that the depth of field is shallow. Focus is manual and easy and surprisingly smooth. In low light it will be difficult or impossible. If you are not a brain surgeon a tripod will be essential for most situations.Once you learn how to use its limits to your advantage it is fine, but there are some shots that will not be possible, especially up close (which for this lens is about 11 feet) where the DOF is very shallow. But to shoot the occasional bird or long detail this is a great lens for the money. Build is solid feeling with metal barrel and nice appearance. I expect non-photographers to take it for a mark of professionals while they ignore my $1600 16-35L.For less than $200, how wrong can you go?

                Good construction. Good optics. Good price. Fixed f/8 or f/6.3 in 800mm or 500mm is common in this type of mirror lenses. Light weight. To get better results for the focusing process use Live View option in the camera if it is possible.
