>>3806860DSLRs from the early 2010s are so affordable right now, it's a great time to get into photography. Whether OP goes with a Canon or a Nikon, there are a ton of good, affordable options.
>The 5D2 has problems starting at 1800 (admittedly high for the time, but I suppose you see how being able to go even higher is a good thing).Oh, I wouldn't say that. In normal exposure conditions, ISO 3200 with the 5DII honestly looks fine to me.
