I cut my teeth on a Minolta X570 and a 50mm F1.7 lens. The D750 is a lust item but the difference in price is a hurdle for me. I would expect the low light focus of the D610 to be similar to what I have. For what I shoot, resolution is not a limiting factor and while the D7000 doesn't always find focus fast in lousy light, it is so much better than my previous D200 that I'm satisfied with it as is. I currently have a D7000 with some decent glass that will cover some FF and am wondering if the D610 will be a significant upgrade in low-light indoor photography? A friend recently bought a D7100 and while it has more resolution and a better auto focus module, it is noticeably noisier at ISO 1600 and above compared to my D7000. I am drawn to the low light performance it purportedly has.

The recent 2nd price drop on the D610 has me seriously thinking.
