The SF is supposed to be the new standard of optics in a birding binocular but to a lot of people the SV is still preferred. It makes a difference to me because if EVERYBODY said the SF's optics just blew the SV away I would have already bought one because I love great optics. Seriously I don't care how much they cost.
Maybe it's just me, but if I read the quote above, I get the idea you would buy a bino of which OTHER people say it it's the best?:eat: I would buy the bino which suits ME best, and I wouldn't give a rats @ss what other people think of it. After all, I'm the one who will be using it.
Regarding the little M7, when you take the "value for money" factor into account, IMO the M7 might be the winner here.
Can I expect a bin which is >6x cheaper to be just as good as the alphas? No. Ofcourse not.
Can I expect a bin which is >6x more expensive, also to be >6x better? Don't think so.
Fact is, when people want the very best, they have to fork out some serious coin for it.
But to be honest, when I had an M7 to test, I had a great birding day with it, and not for one moment I've had the idea that I was missing something. The M7 just delivered:t:
Why did I buy a 32SV then? Because I liked the SV even more, was looking for the very best, and I didn't mind paying the extra €€€ for it. But I'm not everybody.
Downside to all of this, when you actually think you've bought the very best, little quirks can be way more annoying because you simply don't accept them when you've paid so much money.
With cheaper bins, the expectations will likely also be a bit lower, and some shortcomings are accepted.
