My son's just bought himself a birdspotting scope (feathered) with a 50* zoom lense cost him more than 3 grand. He got an adaptor so that he can fit a digital camera to it. Started to take some nice wildlife pics the only problem, he's know finding the slightest camera shake shows up with the high magnification. Stew |

Stew, it is a whole new field of photography once you move into 'extreme' telephoto. I have a 1000mm f1:8 telescope (i.e. about 120mm lens diameter), this thing is huge! It needs a surveyors' tripod and a lot of messing around to get set up but I can get some really good results. High magnification requires either rock steady support or high shutter speed and for high shutter speed you need bright light or big diameter objective lens. For really good results you need all three, or is that four! I am yet to find if my idea of the flash on the gun stock will be useful at night. I know the principle works well during the day though. Your son might already know but if not the sort of vibration you get on a telescope/camera combination can be damped out a lot by hanging something over the telescope, a (small of course) sandbag is good, a heavy coat can be useful but a great improvement can be had just by resting a relaxed hand on the top of the telescope tube. |

Fantastic! - I was wondering what it was all day... I would not be seen out side of my front door with that thing over here! Chris |

John, I remember seeing those sniper sets, I think made by Zenit, in the Naafi when I was stationed out near Dubai in 1970. In those days, lenses of that size were almost unheard of to the general public, and the troops were buying them up as fast as they came into the shop. The largest I ever used was a 500mm preset (all I could afford at the time), a real pain in the backside to focus, manually close down the aperture, take your pic, then open it up again. Most times the shot was gone before you had time to do it. After that, I went to large format 120/220 roll film and Toyo 5x4 plate. They kept me in work for a couple of years during a recession.
