I use a Sony A6000 with Sigma 30mm/1.4. The whole combo is around 5290+3200 SEK, which translates roughly into 62000 INR. When it comes to video, Sony isn't joking around. A6000 can be used for longer videos with an external recorder (it has clean HDMI output) and A6300(which is expensive) can crack up to 4K with S-Log, so you can do color grading afterwards and preserve highlights. For a videographer, DSLRs are not that great, specially since their autofocus modules are completely useless(Pentax, Nikon) and they have to rely on (on)sensor contrast detection. Canon has duel pixel AF, but it is not as refined as the Sony or Panasonic/Olympus AF implementation, specially for bursts and video(still, live view autofocus on Canon is by no means mediocre).
Look at Olympus Pen F and Panasonic Lumix GX8(4K). I will not comment on the prices since those cameras are hard to find. The best thing about M 4/3 is the lens system and quality. Camera might itself be slightly expensive, but you have option to buy great lenses(Look here: M.ZUIKO DIGITAL Lenses - Lenses | Olympus and M.ZUIKO DIGITAL Lenses - Lenses | Olympus). Moreover, Lumix GX8 has excellent video capabilities with weather sealing and is one of the cheapest 4K capable mirrorless you can buy.
When it comes to Sony, they have an (strictly) OK selection of lenses. But they have excellent selection of adapters (Sigma MC-11 is a wonderful adapter which allows most of the Sigma/Canon lenses to work with A6xxx with acceptable autofocus performance). Also, if you are starting with primes, there is option of Sony 50mm 1.8 and Sigma 30mm 1.4, both of which are excellent lenses and are comparatively cheap. Low light performance is also good. These are "small" cameras(A6xxx), that means the built and handling is not as good as DSLRs.
In short (according to me), this are pros and cons for each system:
Sony E-mount: Sony A6000
+Excellent selection of third party lenses using adapters(Sigma MC-11)
+Excellent selection of manual third party lenses(Samyang, Legacy glass)
+Capable enough for videos (A6300 is just too good when it comes to 4K)
+Some really good lenses for cheap (Sony 50/1.8, Sony 35/1.8, Sigma 30/1.4) - and compact too
+/-Autofocus is controversial. Depends on the lens and situation.
+Fast burst rates
-Expensive native lenses(accept for the kit and 50mm/1.8)
-Built is not as solid (But not bad. I used my A6000 in Scandinavian winter, and that is something..-16C and snow)
-Portable only with certain lenses (Kit 16-50, 35, and Sigma 19)
-Don't bother about Zeiss/Sony G lenses and their advantages. Too expensive and you don't want to use the new ones on a cropped sensor.
Note:- Out of camera Sony JPEGs are okayish. Be ready to use RAW as you default format for recording.
Micro 4/3 (Panasonic and Olympus): Panasonic DMC-GX8
+Everyone uses them here for videography (Don't know if that is an advantage)
+Great, Great selection of lens
+Portable and great built
+Excellent in body image stabilization(good for video).
+Again, LENS
+/-Autofocus performance suffers same conundrum as Sony, not clearly a plus or minus
-Bad service in India
-HARD TO FIND
-Cost advantage might be negated by import duties in India
-Smaller sensor, so less depth than APS-C.
-Not really comfortable when used with big lenses
Note:- Out of camera Olympus/Panasonic JPEGs are good.
DSLRs (Canon in specific): Canon EOS 80D
+Good service in India. Availability is good, both for cameras and lenses
+Price
+Excellent selection of lenses
+Good handling(D80) and build quality
+Excellent out of camera JPEGs
+SPEED of operation
-Viewfinder is not as great as Nikon/Pentax
-Optimal autofocus requires use of dedicated sensor
-Not as good as other two options for video(D80 is still a better one out of other DSLRs)
-DSLRs tend to have slight amount of back/front focus, so some lenses might not be as sharp, but you will never notice.
-Big and heavy
-Slower performance when it comes to burst
-Sensor is not as sensitive as other two (20M 4/3 and 24M M mount) for low light photography(D80)
Edit:-
I hear that sony's lenses are expensive. And most of my friend either have a canon or nikon.
So it would be a safe bet for me to go with either of these.
Canon 800d looks like a good option but i don't see it is available anywhere online. so i guess i need to check @local stores before deciding.
also what do you suggest nikon d5500 or canon 750d ? Just in case 800d doesn't come in my budget. Also any link for online deals would be useful as there are not many local places that offer better deals in hyd.
Most of your friends have a DSLRs, but maybe they purchased Canon or Nikon because there friends had those two. Don't fall into this vicious cycle! Go to flickr and see the pictures and judge by yourself. Also, camera is just half of the story, how you use it is something which will define the pictures you take.
Congrats.
