EOS R100vs Nikon Zfcvs A7 III
Which should you buy?
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
Lifestyle, Street & Casual Shooters — Nikon Zfc (2021): Nikon's most beautiful camera — FM2-inspired dials and styling wrapped around a capable modern sensor with Z-mount access.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
