Hi guys,

Just like to check whether a focal length of 200mm is good enough for taking zoo photo?

Generally ,i find it sufficient for me, unless you want to do real close up shots.

Whether a 200mm lens is sufficient will also depend on your crop factor. I'm using a 200mm (at tele-end) with a 1.6x crop at Singapore Zoo, hence effectively 320mm. Sometimes, feel it's a feel lacking in terms of range, esp. where the exhibits are huge and the animals are further from the viewers, e.g. lion and cheetah exhibits in the zoo. Otherwise, it's pretty fine for me. :) Hope this helps.

Sorry. I'm new. Can you elaborate on the crop factor?

DSLR camera generally use a smaller sensor than the 35 mm stadard for SLR. So they are seeing a smaller portion of what the lens sees. Unless u use a full-frame DSLR which will cause a bomb.

Nikon has a crop factor of 1.5x while Canon use 1.6x

i think that a minimum focal length of 300mm is required to shoot in the zoo if you want a really 'wild' shot..i am using a 70-300 with my camera's crop factor of 1.5x, so you will get a pic which is equivalent to a 400mm on a full frame camera. In this way you will get a more 'wild' look as the fences and man-made object can be blurred more. like this one here..

the extra 100mm can really make quite a difference..

as u can see.. tis is taken wif a 70-200 on a 350D. focal length abt. 320mm..


tis is taken wif e S2 IS.. focal length 432mm.


dere is a more up-close and personal look to e S2 shot IMO..

maybe you need a 2.8 to blur more background than a 300

unless you're going to take extreme close-ups,e.g. the head of a lion, you need the background blur. For me, a focal length of 300mm 35mm equicalant would suffice.

imagine you take a photo on a full frame camera. then chop (crop) off the edges, that's why it's called a CROP factor

=> your view angle is reduced (you see less)
=> focal length does not change

to increase focal length, you will need a teleconverter (a.k.a TC)

Well I guess that depends on what kind of images you want to make at the zoo and your preference for wildlife photos. I went to the zoo sometime at the beginning of this year and shot with a 300mm+2xTC on a 1.3x body, giving a FOV of 780mm. I found that just about nice, so it's really up to personal preference, but I personally wouldn't go with anything less than a 400mm FOV.

Try renting a 400/5.6+ 1.4X tc if under budget constraints. Tape up the first two pins to give you AF.
