actually, I would be ruffing a few feathers of members here that believe in DSLR...but I truly think that DSLR is facing extinction soon, in the way of film SLR, and the new era would be that of mirrorless system, either full frame, APS or M43 system, i.e. Sony, Fujifilm, Olympus, Panasonic...etc...so getting a new DSLR now would be questionable (a cheap 2nd hand maybe) as I don't think it will be future proof, given only Canon and Nikon manufacture them (please correct me if I am wrong)...and they have just started trying to play the catchup game of mirrorless...
Of course Canon and Nikon DSLRs would still have a place in the DSLR camera landscape, but it would be on a much diminished scale compare to 10 years ago and maybe left only to the aficionados like film photography is now...only because both companies have invested so much in them as well as people who bought them. but seeing Canon just killed off their last film camera (though production stopped in 2010), I would guess the demise of DSLR is not too far off, though not too soon yet.
DSLR emerged around 15-18 years ago as a bridge between film SLR and the emerging digital revolution...but since 2010s, the advances in mirrorless technology and digital imaging have been relentless. also, in the past 5 years or so, due to advances of handphone camera technology, compact cameras are also on the verge of extinction...save for a few who touted their wares as bridge and/or enthusiast cameras, eg. Sony RX100 series, Panasonic Lumix, Ricoh GRII...etc, which I really like and appreciates.
So now the question for you, as a beginner into a world of photography is...DSLR or Mirrorless?...Full Frame, APS or M43? and to answer them, first you must answer on is: what you will be using them for? will you be printing them (normal or large prints?)? or just posting them online (Facebook, Instagram or some professional sites?)? Is this a prequel to a professional endeavour? or just as a hobby? and of cause, last but not least, budget and future proofing?
