  • 5200mm Canon Lens World's MOST powerful Super telephoto EF FD (updated upload) READ!! Canon 5200mm F14 Prime Lens. The world's largest dedicated SLR Super Telephoto lens. Extremely rare. Made in Japan. Most probably a government ordered cold war spy tool - it certainly wasn't designed to look at the stairs with the use of it's ND filters... 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 ...

  • SOLAR DISTILLED WATER FRESNEL LENS WATER FILTRATION SYSTEM CLEAN DRINKING WATER Solar Distiller. These Water filtration systems offer an alternative to water damage cause by several causes. This solar distiller can creat water deliver of .5 GPH There are a lot of websites that quote the same incorrect information regarding distilled water in soda and mineral leaching. If this were true, and it is not, the aluminum would be leached and water with sugar, or artificial sweetener would become heavy. If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water. Distilled water is not magic, if you add a splash of milk to tea made with distilled water, you now have 10x the calcium of regular mineral water. www.eves- Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. For the rest of the world who usually ingest 15x the sodium recommended, distilled water leaches salt first. ONLY IF you are salt deprived (extremely rare) will distilled water leach excess potassium and or calcium. You would need to drink about 2 gallons in 10 hours for there to be a problem. If heavy sweating, water of any kind is only a thirst quencher or temporary fluid fix.

  • Into the Lens by Yes From Wikipedia: "I Am a Camera" is a synthpop song by The Buggles from 1981 of "Video Killed the Radio Star" fame, from their second album, Adventures in Modern Recording. Trevor Horn and Geoff Downes started writing the song before joining up with Yes. A version of the song was released as "Into the Lens" on the Yes album Drama. When Horn and Downes continued with the new The Buggles album, the song was completed as "I Am a Camera". The two versions feature slightly different lyrics, notably "I will never let you go, and you always let the feelings show" (Yes version) compared to "I will never let you go, if you only let the feelings show" (The Buggles version). In the music video made for the song, during the beginning, there are a pair of Horn's trademark glasses. On one of the lenses is a video and the other is glass. Horn comes out of the video side of the glasses (as illustrated). There are scenes involving Horn singing, broken glasses and opticians' tools. The video is seemingly set in a dollhouse. Towards the end, Horn is seen lying on the floor passed out. The title is a quote from Christopher Isherwood's Goodbye to Berlin (1939). The full sentence reads, "I am a camera with its shutter open, quite passive, recording, not thinking." There was a play (1951) and subsequent film (1955) based on the novel under the name I Am a Camera. Lyrics: Memories, how they fade so fast Look back, that is no escape Tied down, now you see too late. Lovers, they will never wait. I ...

  • How to: Apply, remove and maintain contact lenses READ ME!!! I have used contact lenses in my videos quite a few times and I will be using them a lot more so I decided to do this tutorial showing you guys how to take care of, apply and remove contact lenses. -NEVER apply makeup (eye makeup) before you've applied your lenses or makeup can get stuck behind the lens and irritate your eyes like something crazy. -Also just to be safe, try and wash the lens case with a bit of the solution before you put the lenses in them just in case. -For taking the lenses out of their original container be really careful not to damage them with the tweezers. (the ones I used look metal but they are not. Also the ends are rounded so that they cant damage the lens) If you can (or if you use lenses regularly) get some lens tweezers. These have rubber ends and so will not damage the lenses, I found a seller on e-bay in case any of you are interested (yes I have bought one of these and I do recommend them) : Music by Wesley Avery: The tutorial for the look shown at the end: What I used: -Contact lenses, lens solution and case : DISCLAIMER: The items used (not including the tweezers) were sent to me for free. (I am not being sponsored or paid to use them). I wrote to the company and asked them to send me some lenses to use as they were one of the most affordable and good value companies I had seen.

  • Introducing the World's first interchangeable lens HD consumer camcorder Today, Sony announced the World's first interchangeable lens HD consumer camcorder. The beautiful scenes of Bali were shot using the new NEX-VG10 and shows how interchangeable lenses can help capture beautiful vistas with a shallow depth of field, crisp images of a subject while the background artistically out of focus and rack focus on subjects switching from foreground to background.
