I am a beginner in photography and I have chosen the Nikon D5600 as my new camera, I am looking for lenses to compensate for my needs, which are landscape, astrophotography and general city photography, I have absolutely no idea about any of this stuff and I've ended up with these lenses excluding the 18-55 standard: Rokinon 14mm f/2.8 IF ED UMC Ultra Wide Angle Fixed Lens w/ Built-in AE Chip for Nikon, Sigma 70-300mm and Sigma 10-20mm, which seems like its way too much and I can't imagine people having all this for that. I just want to know if this is actually correct because if so I've massively underestimated how much this will cost and will have to downgrade to a Nikon D3400, which is not ideal. I am sorry I am so clueless about this stuff but if anyone can help and show me a cheaper way to get this quality I would MASSIVELY appreciate it, thankyou.
