Getting a focal length of between 500 and 2000 mm for a digital camera?
Hello!
I wonder if somebody knows anything about this: what is the cheapest way (but maintaining high quality!) of getting the equivalence of a focal length of between 500 and 2000 mm for a digital camera? I now have a Nikon Coolpix 4500 and a TC-E3ED lens that gives the equivalence of a focal length of 500 mm, but I need more for bird photography. Does other camera manufacturers offer lenses similar to TC-E3ED but with greater focal length? I have tried to connect my camera to my KOWA scope but the quality was not good enough I think. I'm looking for accessories that are affordable like the TC-E3ED. For cameras like Nikon D2Xs or Canon EOS 1D Mark III, there are no doubt telephoto lenses that will do the job but the cost would be absurd. Thanks in advance for any polite meaningful response! |

Oh, then get a cheap third-party 500mm lens or if you are looking for higher quality then a high-quality lens. Or a mirror lens. They are dirt cheap and for some applications (although not many) they do work very well. of getting the equivalence of a focal length of between 500 and 2000 mm for a digital camera?

Sorry, with that equipment you are simply hitting the limits. I'm looking for accessories that are affordable like the TC-E3ED. For cameras like Nikon D2Xs or Canon EOS 1D Mark III, there are no doubt telephoto lenses that will do the job but the cost would be absurd. You don't need a D2 or 1D to leverage changable lenses. A low-end dSLR like e.g. the Nikon D40 will do just fine. jue |

Easy. Get closer to the birds.

My problem with shooting "birds" has been with Space Shuttle launches. I have a Celestron C90 mirror telescope using a T-mount camera adapter. It is 1000 mm f/11 on a 35 mm film camera. At one time I used a 2X adapter for 2000 mm f/22 for some of the early launches. This approach might be equivalent to a 3000 mm lens on the 1.5 factor DSLR. However it makes a lousy photograph. I think its shortcomings would apply equally to regular birds. With a mirror lens, there is usually a considerable reduction in contrast. A long focal length lens is usually accompanied by a small f/stop which limits shutter speed. So you would need a heavy tripod and only shoot birds sitting still! My favorite lens for photographing things like birds, is the Minolta 500 mm f/8 AF mirror lens. This particular lens has much better contrast than the Celestron. A conventional refractive lens might be better but would be larger and weigh more. I originally used the lens with a Minolta 8000i film body, but it works perfectly with the Sony Alpha 100 with its image stabilization. For a Shuttle launch last June, the sky was unusually clear. I live about 15 miles from the launch pad, and was able to get some decent shots after it had cleared the trees. I managed to catch the solid rockets as they flew away from the Shuttle, 80 miles away. The image is quite small but recognizable. Yes, you need to get closer to the birds, but you can also use your 500 mm lens and enlarge the images in the computer. Fred |

'You can catch a bird if you put salt on its tail'. Not heard that
expression in a while, however for me it used to be 'You can catch a fox if you put salt on its tail'. ;-) One problem with using something like a 2000mm lens, except the cost, etc. is that you are more susceptible to atmospheric conditions such as haze, etc. The trick is to work out how to get closer to the subject. Of course, with a shuttle, this isn't an easy task. BTW, I would love to be in a situation to live that close to a shuttle launch. If the schedule is cancelled, which is not uncommon, you haven't travelled that far to be disappointed.
