wanted to know about latest Single lens reflex for wildlife?

Hi Rahul, Mostly it depends on your budget. The best wildlife photography equipment should have these features: It should be fast in autofocus, ideally weather-sealed, have a decent continuous shooting speed (burst shooting speed), and light and easy to carry around. If you want to have the images printed to a large size, it should have sufficient pixel resolution (megapixels). Unfortunately, these features appear in high-end cameras, which are on the expensive side. About the lens, the best for wildlife should have about 500mm effective focal length. The lens should be fast enough (i.e., it should have a wider aperture such as f/2.8 etc throughout the focal length. However, f/4 or 5.6 is also considered 'fast' in the case of a 500mm lens). It should have built-in Optical Image Stabilization (look for VR, IS, OS, VC, Power OIS, Mega OIS designations) Prime lenses (one with a single focal length) will give you the best images, but are very expensive, heavy, and inconvenient. So a compromise would be a couple of zoom lenses. As I told you before, the best cameras (especially full frame cameras) are always very expensive. So a compromise would be to buy an APS-C format D-SLR, which has the additional advantage that it will provide a longer focal length for a particular lens. For example, a lens marked as 200mm will provide only 200mm on Full Frame, but the same lens will provide 300mm equivalent focal length on APS-C body. So if you find that a high-end lens-camera combination does not fit your budget, go for an APS-C body that you can afford and combine it with a high-end lens. There is yet another option if this appears too expensive or very heavy to carry around. This is a Micro Four Thirds (mirrorless) body such as Panasonic GH4 (excellent choice) or Olympus OM-D E-M1 or E-M5. The advantage here is that a 200mm lens will provide 400mm equivalent focal length. And these lenses are very small and lightweight compared to Full Frame lenses. Whatever camera and lens combination you choose, the most useful equipment will be a sturdy tripod because at long focal lengths, there is always chances of camera shake. I would suggest the Nikon D3300 over the Canon EOS 1200D (I am a reviewer and I have compared both). read less
