How do I use a 500mm lens in nature photography?
I have a Sigma 500mm lens last year, took him to Botswana for shooting wildlife, do not use it much. It's not that I do not want to use it, but I do not know how. I usually just use my Canon 100-400mm with a 2x teleconverter, but the f / stop is too high. So I want to know, from anyone who is experienced with these super-telephoto … How do you use? I can almost NEVER find the animal / object through the viewfinder with a long focal length. Thank you guys a ton.
it is a HSM? … f2.8? for a long time one of these lenses probably hide me inside a van or somewhere high to establish a tripod with cable release too …. and have pointed to a place of high traffic then play the waiting game … time with something that is difficult to keep it moving

You should have seen the flower as a device attached to the many lenses. Sometimes, or find them in normal lenses also, what are they? If you have had occasion to see a film professional camera, you would have seen a device like a elephant ear attached to the front the camera, they are called, matte boxes.
Lens Hoods
The main purpose of these devices is to avoid glare and reflections. Now, coming umbrellas, again, there different variants. The basic version is similar to a lampshade, which are used in the objective of this work in the upper parts of the region tele because the viewing angle is narrow in these regions, which often leads to vignetting blocking the field of view of the lens. Today, we have objectives that may vary across regions telephoto. When is used as a lens, we can not use normal because umbrellas would vignette on entering the field of view of the lens.
Design Considerations
This problem is solved by using specially designed umbrellas that have been designed taking into account the angle vertical and horizontal viewing separately. In general, the horizontal viewing angle is greater than the arrival of sunlight angle vertical and vertical. The result is a design that looks more like a petal or a flower. The bell for each objective must be designed taking into account the angles of this objective to prevent vignetting. Parasol also be used in order to protect the lens against physical damage. Some umbrellas for the camera, "prosumer" Models are available creating filters or TV in them. In the world of macro photography, shorter parasols are available with LED rings fixed provide adequate illumination of the subject at close range. These hoods are extremely versatile and offer a greater degree of freedom for the photographer. Sometimes they have integrated their battery packs, etc., which may some time that the camera a bit heavier than the impact on the stability front.
Matte Box
They are mainly used in video segments in the segment of pictures because you can define the length of the fins. The fins are called French flags and the possibility of French flags them greater freedom and flexibility. They are used in photography, too, but less visible and are limited primarily controlled environments like a studio, this is mainly due to the large size of matte box. They also serve the purpose of providing a place to attach filters of glass or plastic. Matte boxes are used in the video segment, because most of them are killed in controlled environments. Matte boxes are sometimes the photographer himself to your needs. Some companies that manufacture and above all, are not the camera or lens of his duties because they have adjustable components.
Mixing the two has been developed which resulted in a hood adjustable petals, but they very well and have left the market right now.
Thus, when buying a lens for your DSLR, it is advisable to buy your umbrella because it also gives you an advantage when shooting in direct sunlight. Will a better contrast and images look more dynamic when using umbrellas, and maintains the angle of sunlight falling on the elements to its target. The table below should explain better.

One way to find the value of things is to use the advanced search eBay (just to the right of the regular search box), then check the box filled with ads and click on Search. EBay France showed that only two Canon T70 was included recently had an offer of £ 25.00 and one with flash and lenses sold for £ 50.00 http://cgi.ebay.co.uk/Canon-T-70-camera-kit_W0QQitemZ220363181376QQcmdZViewItemQQptZUK_Photography_Film_Cameras_ET you look here? hash = & _trksid item220363181376 P3286.c0.m14 = and = 66% _trkparms 3A2 | 65% 3A13 | 39% 3A1 | 240% 3A1318 You should keep in mind that eBay is the light "invisible" prices and would be better in an auction dedicated camera, but you must pay commissions. The problem with Canon is that the team can not be used a digital camera from Canon, because of poor backwards compatibility, Nikon and Canon are looking to other prices higher because they can. Separation of elements generally provide a better overall price, but the ancient art of Canon cameras since they were fantastic do nothing as its real value, it may be better to just stay with it or use it in a paper bag.
