Share some pic on my recent trip to Penang. Only managed to get a few shots:

For me it is fake  . because flare is not just  something that simple round yellowish thing

That's the combination of a bright aperture and fairly high ISO. Catch the ambient while preserving the shutter speed.

That's why I say : Don't be afraid to use high ISO! If you resized to seeing on screen, you practically cannot really make out the noise.

You can see the bright aperture setting when you notice that most of the frame is already in bokeh. It helps if your subject is strong so people will not notice it as much the 'blur, blur' areas.

Another thing is that the 50mm on a FF is very versatile!! Thus if you have aps-c, it's time to consider the 35mm lens. Let's you take a lot of stuff with just one lens. Prime lenses also help you with your composition. You know you cannot zoom so you need to move your arse around to get a good angle. After a while of doing this, you will learn to recognize fairly good angles.
