Before I got my DSLR, I am just using canon compact camera SX200. I bought it because it has 12x zoom. When I was younger I always like ultra zoom or super zoom camera. I thought camera with greater zoom is better. But that is not the case. Eventually I know the widest and longer end of zoom range didn't offer much image quality.
Before you start, you got to decide what Brand of DSLR you want to buy. Personally I won't get anything other than Canon or Nikon, the reason is simply because both of this brand is already long in market. They are also many 3rd Party lens available for it. As for Sony,Samsung, Olympus and even Ricoh don't have much choice. But you can still make your choice.
If you go for canon. Get the Canon 550D Body which cost about RM 1900. For Nikon get the Nikon D5100, that cost about RM 2,000 which is about RM 100 more expensive than canon, but of course with better features and screen function like canon 600D. But we are not here to compare the performance. Of course for canon you can get a 600D that cost RM 2300 + which is RM 400 more expensive.
Next you will choose between wide angle, portrait, general photography OR Telephoto and Macro. Or you can get Both the lens depending on your budget, If you are on RM 3000 budget you can only get one of the lens. I suggest you go for shorter focus length with general photography, wide angle landscape and portrait photography. Generally, 70% to 80% of time you will be using the 17-50mm Focus length. Since you will be using it a lot, you should be getting something good and not too expensive until you are ready to go further
I suggest the Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical [IF] Lens that cost about RM 1200. With either Nikon or Canon Mount, it will come close to RM 3100 to RM 3200 budget. Perhaps you should top up a few hundred if you can get a better bargain. This lens is sharp enough to give you very good image quality. It is cheapest among the sigma, Nikon and Canon brand. If you have extra budget better save it now, don't go for VC version that is 500 bucks more. With 500 bucks you can get another decent and fun lens.
Many of you will be wondering why we should not use the original kit lens, which has the same zoom range from 18-55mm. This kit lens has F/3.5 to F/5.6 which I personally think is too slow. With F/5.6 at the longest end, you can't take a good Bokeh portrait picture. At the widest F/3.5 the image quality is really bad and most of the time you have to stop down to get a decent image quality. But the lens will cost you RM 600 if you purchase it separately, but of course it should be cheaper if you get it with the camera body. For canon, now you have upgraded version that have a bit of image quality. But nonetheless, I would recommend Tamron Lens with faster aperture, better image quality and decent price tag.
That's it, you can now start shooting good images with this budget body and budget lens. Tamron lens generally covers wide angle at 17mm till 50mm that you can shoot quite a good portrait. If you have extra 500 bucks budget you can get another cheapo lens that allows you to do some telephoto + Macro. Get the cheap RM 600 Tamron AF 70-300mm F/4-5.6 Di LD Macro 1:2 Lens
This Tamron lens, is cheap and let you to learn about wild life telephoto without Image stabilization. Why no IS/VC? because with IS/VC the lens is about RM 1,000 more. and it will sacrifice its Macro capability. With a price tag at RM 600, you can't complain much about the sharpness. It is basically quite good compare to the same entry level lens even on canon 55-250mm, the sharpness is comparable. Remember, we would just like to experience and practice telephoto shooting. Thus we do not want to have something price between 1k to 3k which will still be a slow lens with lousy image quality. Other than F/2.8 or F/4 constant aperture from any brand I would not recommend investing into telephoto yet. So save up if you want to have a good telephoto lens. But most budget and best quality I would recommend a sigma 70-200mm F/2.8 or Canon 70-200 F/4 IS.
With This telephoto lens, you can have good macro photography from a distant. It is fun lens to play with. Once you reach the level of professional, you will feel this is a "toy" lens. That's the time you need to upgrade your lens. Remember on longer end just stop down to F/7.1 or F/8.0 to have a great image. Just capture it with higher shutter speed and ISO. dont worry about the noise, you can reduce it if you capture it in RAW.
With a budget around RM 4,000 you should be able to start practice on all the focus length. Once you know have identified your interest, you should be able to move to better lens.
For Portrait, get the sigma 50mm F/1.4, yes PRIME lens without zoom that will have best image quality compare to zoom lens.
For longer end, get 70-200mm F/2.8 or 100-300mm F/4 or equivalent.
Don't focus too much on ultra wide angle until you have upgrade to full frame.
If capture the moment, it is pretty easy if you have the suitable gear. But you will not have a stunning image. Once you feel that your crave for more image quality, is time for you to upgrade to full frame and put both tamron lens in your cupboard or sell it with your APS-C body.
When you move to full frame, most of the time you will want a prime lens to get the best out of everything. Each prime lens with superior image quality should cost you more than RM 5000. with that you should seriously consider your investment plan before blowing up your wallet.
