Description:
Canon 5200mm F14 Prime Lens. The world's largest dedicated SLR Super Telephoto lens.
Few were made & I stumbled across this one - pulled out of dusty storage in China - minus scopes & lens adaptor mount. Though the lens is made in Japan of course.
It uses a mirror & lens combination. The front lens is massive.
Rear drop-in filters can be used.
•Focal Length: 5150mm
•Exposure Control: Light quantity is controlled with the use of built-in ND filters, corresponding to f/14, f/16, f/22, f/32
•Minimum Object Distance: 120 meters (Approx 393 feet!)
•Size: 500mm(wide) x 600mm(high) x 1890mm(deep) [20x24x75.6]
•Weight: 100kg (220 lbs) without stand.
From a Canon Flyer:
"This is the only ultra-telephoto lens in the world capable of taking photographs of objects 18 to 32 miles away (30km to 52kms away). Having a focal length of 5200mm, Canon Mirror Lens 5200mm can obtain one hundred times as large an object image as that of a 50mm lens."
"For focusing this mounted or fixed lens on an extremely distant object, two aiming telescopes are set on the side of the lens barrel, and the entire lens is placed on a rigid stand which rotates smoothly. Minimizing the overall length had been a big problem in designing this lens. However, the Catadioptric system that is applied to the other two Canon mirror lenses (Canon 800mm f3.8 & 2000mm f11) has succeeded in reducing it down to one third of the nominal focal length. In general focal length and optical aberration increase with each other, however, our long and persistent research and development have succeeded in solving this problem. Canon mirror lens 5200mm composed of spherical main and secondary mirrors and a correction lens would assure you of clear images."
The magnification of this lens is truly staggering.
If mounted to a Canon XL HD series video camera for example, a reach of 1000x optical (at least) would be possible (approx 37,500mm).
Capable of taking shots 18 to 32 miles away (30km - 50km)
If it was mounted on a DSLR with a crop factor the magnification would be larger still.
The video is a series of stills I took of the lens when I inspected it last year. I have also included video of the simulated magnification - all a bit of fun. In fact the maximum video telephoto simulation still just falls short of 4000mm in 35mm terms. So the 5200mm would be much closer & far sharper & distortion free. The video was shot with a Sony PDW 510P 16x9 2/3 SD XDCAM disk camcorder with a lens using up to 3 optical extenders.
If anyone has some other information about the 5200mm lens - its history & uses please post and or message me.

50 inspirational ideas for photography
From here
Credit goes to the original author
Inspiration is a powerfull thing but doesnt seem to come past as often as we like.
Here are 50 ways to breathe new life into your love of photography and re-energize your inspiration.
1. Play with Photoshop
So much of photography these days happens after the shutter release has been pressed. There’s probably a ton of things that you don’t know how to do in Photoshop. Photoshop can remarkably change images , Learn something new and see what that does for your photography potential.
2. Read the Manual
It’s not just Photoshop that can do all sorts of things that you don’t know about. Your camera probably has more settings and functions than you know or know what to do with. You might find a lot of new ideas in the middle of your camera manual.
3. Watch a Movie
Manuals are all well and good, but movies have cinematographers too. I find that music channels are very good for portrait photography, turn the sound off sit back relax and let it work its magic.
4. Read a Magazine
It doesn’t just have to be a photography magazine, ALL magazines have images in.
5. Check out Some Wedding Photojournalism
The traditional staged posing with a tripod has almost been removed from wedding photography, the bride and groom prefer a much more spontaneous real life images that capture the moments. Wedding photography is a good way to see how to blend into a crowd and document an event.
6. Hit the Water
How gorgeous is underwater photography, if you don’t have underwater housing or an underwater camera tries to incorporate water into your images. Water can be used in clever ways as it is so reflective, the lighting has to be near perfect but some of the best images are when the light hits the surface of the water.
7. Hit the Streets
There’s a good reason that street photography is so popular: there are so many good things to shoot there. Peoples expressions, crowds, clothing, colours, landscape, buildings it’s all there.
8. Join a Demonstration
Demonstrations are full of flags, banners, placards and crowds. You can lose people in the mass or pick out expressions in the crowd. The only cause you have to support is photography.
10. Watch a Sports Event
The pros have it easiest at sports events with prime positions and lenses longer than your arm. But you can still try something new at your park on a Saturday afternoon.
11. Visit the Zoo
It might not be as thrilling as a Kenyan safari, but a zoo still has the sort of photographic subjects you can’t find anywhere else. Of course, you don’t have to try to squeeze your lens between the bars. Shooting the kids in awe at the monkeys can create some interesting images too.
13. Shoot Fast at a Race Track
Race tracks also give you an opportunity to use a new technique: speed. Fast cars and a faster shutter speed can make for some inspired shooting.
14. Visit an Exhibition
Obvious, really. And yet so often overlooked. Any decent-sized town is likely to have at least one photographic exhibition on at any one time. Take in yours and see what the top photographers did to get on the wall.
15. Browse Google Images
You don’t even have to leave the house to find inspiring images though. Toss keywords into Google Images, admire the good photos that turn up and ask how you would have improved the poor ones.
16. Join photography Groups
The pictures in Flickr Groups are great places to see what other people are doing with a theme; the discussions are great places to find out how they did it. And you’ll probably find that the feedback you get on your own photos will give you plenty to think about too.
17. Just Step Back and Watch
For children’s photographers in particular, there can be a temptation to just dive in and get the photos. Sometimes though, lowering the lens, stepping back and watching the subject can reveal whole new sides. That’s true for portrait photographers, wedding photographers, and animal photographers… in fact just about any photographer.
19. Change your Angle
Most people shoot an object by placing the lens right in front of it. Different angles and viewpoints can create interesting compositions.
20. Change your Time
Find yourself shooting at the same time of day each weekend? So break a habit. Discover what the light at dusk, mid-afternoon or early morning can do for your ideas. And it’s not just the light that can make the difference here. Just breaking your routine can often be enough to give you a new perspective and a whole new way photography habit.
21. Read a Blog
Of course, reading a photography blog is even more inspiring thing than writing one. Not only can you learn what went into a photo and where the idea came from, you can also discover how to sell it. But then we would say that, wouldn’t we?
24. Buy a Photography Book
You can never own too many photography books, and each one you buy should give you a bunch of new ideas. Although that’s true of both books of photographs and books about taking pictures, you might find that photography guides give you more inspiration than a collection of images. The former will give you techniques to try out, while the latter will show you the techniques the greats have used. Still, if you’re really stuck, go shopping.
25. Make Friends in the Photography World
Some photographers find it easiest to shoot alone. Others like to shoot as a group. Everyone can benefit from the feedback, discussions and habits of other photographers.
26. Join Photography Organizations
If you’re a professional and you’re not a member of a professional photography organization, you should be. Not only can organizations help with insurance and legal matters, their news, contests, and profiles of other photographers can inspire to make your own splash among your peers.
27. Shoot Yourself
When you’re stuck for a subject, always remember that there’s an interesting one behind the lens too. Be brave. Put yourself in the shot for a change.
28. Revisit Your Past
You probably have a stack of old images that you rarely review, including many that you can’t bring yourself to look at. Give them another chance. A shot that failed a few years ago might well be achievable today and give you ideas for more.
29. Revisit Places You’ve Been Before
And the same is true of locations. Even if you’ve taken a photograph in one location, it doesn’t follow that you’ll take exactly the same image a few days, months or years later. The light will be different, your skills will be different and so will you.
30. Ask “What if…?”
Some of the greatest artistic answers have come from asking the right questions. A good one to start with is always “What if…?” What if you focused on the foreground instead of the background? What if you changed the ISO? What if you got a flash of inspiration?
31. Join Photo Contests
Everyone and their uncle these days seems to be running a photography competition. And for good reason. They’re a great way to motivate photographers to shoot outside their boxes.
32. Choose a Theme
Most people work to deadlines, themes or times. Everything is easier when you narrow it down give yourself a theme e.g. Alice in wonderland , it may be an overused theme but there are many things you can do with it.
33. Go Back to the Rules
You probably know the rules of photography. And you probably know how to bend them and when to break them too. So maybe go back to when you were first learning techniques and try working strictly to rule for a while.
34. Just Shoot Anyway
There are always times when you lift the camera, look at the screen and think, “No.” But what would happen if you did it anyway? At worst, you’d waste a bit of disk space. At best, you might surprise yourself and find a new kind of composition.
35. Get a Cause
Few people are more motivated than those who believe they’re working for the common good. So join them. Pick a cause, offer it your photography skills and the end will help inspire the means. You could find yourself shooting all sorts of things from campaign posters to t-shirt images to angry demonstrations. The variety should be as satisfying as the campaigning.
40. Play with Textures and Colors
While photographers often pay attention to light and composition, the texture of the materials in the subject can be left behind. Try focusing on touch rather than vision for a few shots and see what happens . Ttry using different tones of just one or two colors and see what that does for yourt results. Also think about taking color away B&W images are very bold and can give many emotions off.
41. Play with Settings
Chances are, once you’ve found a camera setting that works for you, you don’t stray from it too far. So start straying. Play with the exposure, change the ISO, switch the shutter speed. And build on the results.
42. Try a Different Specialty
Whether you specialize in wedding, portraits or anything else, try a niche you’ve never done before. You don’t have to do it professionally but just doing it for a while could give you a whole new bag of techniques and inspire new ways of creating your images.
43. Start a Project
Inspiration might come in a flash but you want it to hang around. Instead of thinking of an idea for one photograph, try thinking of an idea for a series of photographs. If you’d decided to take pictures of lightning for example, expand the concept to include extreme weather as a whole and add photographs of windswept trees and sun-bleached rooftops. That should keep you busy for a while.
44. Define the Perfect Image
Do you know what the perfect image would look like? Bet you’re thinking about it now, right? Instead of thinking how good the next shoot would be, try thinking about what the best shot would look like then find it.
45. Create a Shooting Schedule
One way to cut back on the regular head-scratching is to plan ahead. Pull out a calendar and decide in advance what sort of images you’ll be shooting each weekend for the next few months. And leave room for flexibility.
46. Pick a Different Model
If you always use the same models or models with similar looks go for something completely different: the opposite sex, a different height, a new age group. See what a different subject can for your ideas.
47. Do Something Totally Outrageous
Ever told yourself “That would never work?” Well, here’s a “what if…” What if it did work? Go ahead, surprise yourself. Shoot what’s under the sofa. Snap the top of your head. Do something outrageously silly and see if it works.
48. Tell a Story
Good pictures always tell a story. So try thinking of a story then go out and create the images that illustrate it. That could be the story of your street, a narrative describing a community or even the progression of a cub baseball team. Find where your story begins then use your camera to follow it through to the end.
49. Buy New Equipment
And if all else fails, you can always use cash. A burst of new ideas always seems to come free with a new lens.
50. Just Play
The beauty of digital photography is that there’s no penalty for making
mistakes. That gives you a free ticket to stop worrying about whether a picture will turn out well or be an embarrassing flop, and just shoot. So try just enjoy taking photographs without thinking too much about the results.
