Reddit mentions of Nikon D5300 Digital SLR Camera Dual Lens Kit

My 2 cents as a long time hobby photographer with somewhat similar interests (I shoot nature, at macro and telephoto distances).

Just about any modern DSLR body will be able to do what you are asking for, but you will need very different lenses for both purposes.

Sensor size is the main factor to consider in modern DSLRs.

Full Frame bodies have a sensor inside that is equal in size to one frame of a photographic film. APS-C or crop bodies have a sensor that is smaller than photographic film, therefore you have a "crop factor" (1.5 or 1.6) which represents the part of the image produced by the lens that is captured by the sensor. In effect, this is equivalent to cropping out the edges from a full frame image. Micro four thirds is a sensor standard that is roughly half the size of a full frame sensor and cameras featuring this standard are very compact (this is related to flange distance [distance from sensor to the lens], not sensor size, but that is not important here). Pentax, Canon, Nikon and Sony make both full frame and APS-C bodies, Fuji makes APS-C bodies and Olympus & Panasonic make M4/3 bodies. I'll stick to Canon and Nikon in my recommendations here because other manufacturers are not well represented in India.

Macro

There are 4 ways to shoot macro images;

(i) The easiest way is to use a dedicated macro lens. These are lenses optimised to focus at very close distances. A "true" macro lens produces 1:1 or life-size images. What this means is that at the closest focusing distance, an object the size of the sensor will produce an image that fills the complete image frame. The Nikon 60, 105 and 200mm, the Canon 100 and 180mm, the Tamron 90mm, Tokina 100mm, Sigma 105 & 150mm are all excellent lenses. These are all moderately to very expensive, so I recommend looking in the used camera market. Most macro photography is done with manual focus, so you may be better off purchasing an older manual focus lens for 8-15k, than a newer auto focus model for 20k and up.

Pros: Excellent image quality, lenses are all built to high standards.

Cons: Cost.

(ii) Reverse mounting a zoom lens. The use of an adapter allows you to attach a lens (such as a standard 18-55 kit lens) the wrong way around and take magnified images.

Pros: Inexpensive.

Cons: Learning curve, lot of trial and error. Image quality not as good as a dedicated macro lens.

(iii) High quality close-up diopters (such as a Raynox DCR-250, Canon 250/500D, Nikon 4/6T) can be attached to the front of just about any lens to provide magnified images. You can also get cheap "close up lenses", but these will provide poor image quality. The diopters mentioned above are doublet or triplet (made of 2 or 3 lenses) assemblies that will not affect image quality to a great extent.

Pros: Pocket friendly.

Cons: None really, unless you want to nitpick.

(iv) Extension tubes are hollow tubes you place between the lens and body which magnify the image produced by the lens thanks to simple physics.

Pros: Inexpensive.

Cons: Take a bit of getting used to.

Sports

Taking pictures of fast moving objects at distances requires the use of long "telephoto" lenses. I would recommend a 300mm lens as the very minimum if you want to take pictures at cricket distances (assuming you're sitting in the stands of a stadium and trying to photograph the batsman). As telephoto prime lenses are rather large, heavy and expensive, you're better off going with a zoom lens right now.

Keeping your budget in mind, the best deal right now might be the Nikon D5300+18-55+70-300 for 48,000. The 70-300 AF-P is a pretty good lens that focuses down to about 2 feet and gives you a magnification of 1:4. Add a Raynox DCR-250 for about 7k and you have a pretty nifty macro set-up that will do a decent job with sports as well.

If you want something a bit more rugged, I'd suggest a used Nikon D7100 for about 25,000 coupled with the 70-300 AF-P for 17,000. A Raynox diopter and an 18-55 will add 10,000 to the cost.

The Canon equivalent of the AF-P 70-300 costs 36,000 (although the 55-250 can be had at that price), unfortunately. Which does not leave much for a body. There is an inexpensive Canon 70-300, along with Tamron/Tokina/Sigma variants in both Canon & Nikon mounts, however none of them offer Vibration Reduction (which the AF-P does). VR corrects for "lens shakiness" and is quite useful for beginners. Entry level Canon bodies also offer a somewhat less featured auto focus implementation compared to nikon.

If you want to go with Canon, I'd recommend the 750D+18-55 combo for 47,000 combined with the 55-250 IS for 12,000. Or, you could go with a used 7D (a 10 year old body, but still quite capable) for about 32,000 and couple it with the 55-250.

There are additional options if you'd like to restrict yourself to one form of photography. You'll also get lots of useful information if you ask this question on the photography & camera sub-reddits, as well as Indian photography focused sites such as the JJ Mehta forums.

The real money sink in a DSLR platform is in the lenses. Macro lens for small insects, needs to be moderately fast, with image stabilization. Telephoto lens for sports. Base body with kit lens. Will not fit within the budget. What I can advise you is to get the Canon 1300D with 55-250 and 18-55 lens bundle for 33k or Nikon D5300 with 18-55 and 70-300 lens bundle for 48K. The D5300 is a better body but the Canon bundle will let you save some money towards a real macro lens if you are serious about macro.
