Why not to (over) invest in APS-C lenses

APS-C lenses are great, cheaper and lighter

But if you want to expand your equipment and combine APS-C and full frame cameras the APS-C lenses will not work on your full frame body. So think before investing.

If you are a beginner

I strongly suggest start with a reasonable APS-C camera. They are lighter and also cheaper. Consider buying used equipment. Whatever advantages you think full frame camera is going to have, you will not need it. At least not in the beginning.

Kit lenses are a great way to start. They are usually universal zooms with a very reasonable range, and to keep prices in check are made APS-C only. This works great for almost everyone, from people that want to get more involved as well as people who 'just want to take a bunch of pictures. There is nothing wrong with that.

If you want to get better

Take a lot of pictures, examine pictures you and also others have taken and try to understand why you like them. Try copying them.

If you think you will need more equipment to get better, well maybe it is time to consider using prime lenses. At this point, just consider that you might want to have another body. I argue that if you want to have more than one body, it makes sense to combine APS-C and full frame cameras. This is why, I would suggest to consider buying lenses that would also work on full frame cameras, just in case.

Counterarguments, stick with APS-C

Well, you do not really need more than one camera to start with.
You also do not need many lenses.
APS-C only lenses are smaller and lighter. One of the most important things in photography is making sure that you carry your camera
Full frame lenses are also (usually) more expensive
If you want to have two bodies, it is also perfectly OK to have two APS-C bodies.
Wide angle zooms do not work well between APS-C and Full frame cameras. The Nikon 16-35 on an APS-C works like a lens of 24-50mm focal length, it is different and still sort of interesting, but you will most probably not carry a 700g lens for that on your APS-C camera.

There you have it. But on the off chance that you still want to combine APS-C and full frame cameras, then maybe spend your money on full frame lenses. Cameras come and go, but lenses stay longer, full frame lenses can be used by a larger number of cameras than APS-C only lenses.
