Buying advice - replace lens, go prime, or just get another camera?

[EOM]

Just for an example I recently bought the 40mm pancake for my 6d since I was doing some traveling and didnt want to carry around a bunch of heavy lenses. I bought it for the reason of convenience and weight, so for me it is a good lens. If im wanting to take portraits than I use my 135L. My lenses all have a purpose. The 50mm outside of cost is an extremely overrated lens that is bought and then most often sold soon after.

That's how I ended up getting both the 24mm and the 40mm pancakes for my wife.... they're light, small....and most importantly to her... "cute"...

As for the 50mm.... for used prices around 80 bucks... it can almost never hurt to have that in your bag because why not. It's a cheap way to get a prime lens with a wide aperture. A lot of wedding photographers bring 50's for backups since they're versatile and not terribly heavy.
