A semi professional camera is a little ambiguous.
You either have a point-and-shoot types or the Digital SLRs.
We all know the xx mp digicams, but they offer no professionalism. Its easiest to use, has more technology, faster, lighter etc.
But the SLRs are made with bigger cmos sensors, which are capable of a much more clear imag with better quality of every pixel. Having said that, I recently went into the SLR thingy and got myself a Canon Rebel XTi, alongwith an additional lens of 75-300. A 18-55 was already supplied with the camera. The whole thing cost me around $1K. The reasons I chose the XTi were:
1. One of the more latest cameras with advanced technology.
2. Ease of use despite being an SLR
3. Self cleaning C-Mos sensor.
4. The first camera which grew out of the 'Sony C-mos' reign. (All cameras in the world had Sony C-mos sensors. Canon made their own for the first time, and saved on costs, which is eventually passed onto the buyer)
5. Several opinions and e-feedback.
6. Durable and very good battery back up. Lasts around 1000 pictures.
Now, the difference between the SLR and Digi-cams are several. You can read a lot of them on the web. But getting an SLR will no way make you a great photographer. You will have lots to learn and lots to experiment. But once you get the hang of it, you cant be seperated from it. Matter of fact, since I am not finding the time and enthusiasm, I have just put up my SLR kit for sale. If you get one, you should be prepared for a lot of extra work, which will matter widely from what one usually gets to do with an Digi-cam.
If you decide to buy, make sure you get an additional lens alingwith it. You should have a combination like 18-70 and 75-300 lens. The former is good for closer distances, while the latter is for closer zoom of distant images. There is a lot of optics involved, and you would not want to get yourself one 'combined' lens like '25-300' or so. They will have certain aberrations (distortions) which technology has to still solve.
You will find several cameras in most showrooms in India. But the MRP of the Indian shops will be about 35-70% more than what it costs in US or other countries.
Ensure you know the guy you are buying it from.
Check the camera, preferably with someone who knows cameras well, before buying.
Once you get the hang of it.. I am sure we, at IFG,. will see a lot of pics
I will, after you buy, send you a variety of links for online download of SLR training material.
