What kind of equipment do I need to buy to learn portrait photography?

I think we need at least a simple camera+a lens equivalent to a full-frame 50mm F2.0 (it's really not good, F2.8 is actually reluctant.

camera

I think it doesn't matter if the camera draws half, unless you want to enlarge it. Otherwise, if you print, share, etc. Normally, it seems that the difference is not particularly great. At most, at night, Quan Huafu has excellent noise suppression and more accurate color reproduction.

camera lens

Then there is the lens.

If there is only one, then I recommend a focal length of 50mm (Quan Huafu). Because it balances ambiguity, volume, price and many other things.

other

As for other things, such as reflectors and lights, you must prepare them in the future, but I don't recommend novices to spend too much time on them. Laying a good foundation before upgrading is the most scientific method.
