I saw tenglong 150 - bird shot 600 mm lens to try

in this paper, from a hummingbird net
birds, seems to be a threshold of low activity, because seem to use any equipment can be taken with birds as the theme of the film; Birds to shoot, it seems that it is a very high threshold activities, in addition to the preparation of professional knowledge, strong fatigue, but also have the ability to super equipment to shoot film. All images used tenglong - in this paper Mm lens. Mm:

the focal length: f ISO sensitivity:
time: s compensation: EV white balance: automatic
as the primary demand is: birds filming equipment fast. The bird photography there is a proverb called: 'have to' first. Means only finished making photos, there is a possibility of further improve optimization, if can't shoot the bird, the many high quality beautiful designs are empty talk. The following figure, a sinian crow bird flew from reed deadwood, although increased sensitivity to ISO, time is shortened to seconds, but because of the speed remain a subject is not clear enough. Mm:

the focal length: f ISO sensitivity:
time: s compensation: EV white balance:
the following diagram automatically, a common yan plovers from overhead, use ISO ISO, time is shortened to seconds, record the moment.

the focal length: mm: f ISO sensitivity:
time: s compensation: EV white balance: automatic
birds filming equipment second demand is: long. For this requirement, bird photography called 'how long is not long enough'. Although in certain the humans and birds, especially wild birds can achieve very close distance, but to minimum may interfere with the normal activities of birds, is top priority with your subject well-being, shooting birds or take a longer focal length. At this time requires more than mm focal length to complete. The following figure, a group of white spoonbill in shallow water area, far from the shore foraging and comb, shooting distance more than m, use the focal length mm, cause the topic is too small, almost impossible to distinguish features.
convenience
birds, shoot the bird equipment of the third requirements of the device is: convenience. Seems to be the bird filming equipment has had such an understanding, fixed-focus no convenient, zoom without quality. As a result, most birds who are in pursuit of big prime lens. But in actual use process, changing the distance and may be looking for long distances, and so on and so forth, the recent focus distance constant volume weight of fixed-focus equipment does not apply.
as the following two figure: sinian crow finches and eastern big WeiYing belong to smaller birds, and live in the reeds, keep out more. Therefore need to be taken more looking for, judging its action, this time need to be taken handheld devices at any time. In the case of portable equipment or convenience is particularly prominent. If the device is overweight, the photographer premature fatigue failure in the shooting opportunity arises when finished making; Or because the device when the volume is too large in the shrub and grass through peg to the obstacles losses lead to falling so that equipment damage.

the focal length: mm: f ISO sensitivity:
time: s compensation: EV white balance: automatic
birds filming the final requirements of the device are: quality. This is the final demand, is also the most important requirements. Quality this problem contains two aspects, on the one hand, the lens imaging ability are strong enough to adapt to each kind of light, distance and air under the transparent degree requirements, on the other hand and camera lens to good cooperate with high quality records for later use. So a reliable lens became a powerful shooting action.

the focal length: mm: f ISO sensitivity:
time: s compensation: EV white balance:
automatically such as more than two figure: black prehensile tail feather pure black body, and the strong sunlight than super light, and although reunite sun exposure, but the dappled light dark forests, which brought great difficulties to the shooting, but the equipment of my hands in the complicated and changeable situation provides a quiet, fast focus and clear real image quality.
