That's the point - looking at the ease of view and the brightness is only one side of the equation. Sure, theoretically bigger is always better, at least when it comes to scopes. But you pay a...

If you check the old Hensoldt Dialyts, you'll find plenty of of models with smaller apertures. They're longer, of course, but very slim. All with AK prisms.

Same here. I switched over 35 years ago. I do have a straight scope as well though - exclusively for use from the car. That's the only situation where a straight scope has some advantages.

And if you want to keep the price (and the weight) down even further, get a D7500. It's AF is a heck of a lot better IME than the AF of the D7200.

If the AF is really better than even the AF of the D5 - and I don't doubt it is - it'll be a killer. And just like the AF of the D5 led to better AF in other models, I think there'll be a DSLR with...

Actually, a well-made porro doesn't need ED glass. The problems with CA only reared their ugly head when the manufacturers introduced focusing lenses behind the objective lenses.

No, you're right. The 20/30/38x are different. Both versions of the 16/24/30x are the same (except for the coatings).
