No, I haven't bought anything via auction on eBay in a considerable amount of time. Anyone should be suspicious of a used item sale from Japan (and one of those was recent, IIRC) where the sale price is greater than a new item easily bought from multiple well-regarded sources here.

Still don't know who actually bought those lenses in Japan for over $500 as there's no mention of the buyer or auction history.

Not sure who these people are that paid "500+ used" for a lens that's new at B&H, etc. for $497.

The value proposition is regional. In the USA, the premium for the DA 16-85 over the DA 18-135 is about 11% at the moment. That changes the question substantially.

What is a "walking around lens" unless it's the one on my iPhone (which does walk around with me often)? The category is mid-range zoom and it's not defined by what anyone thinks it should never be used for. If we get too many people playing that game, ultimately we'll conclude the lens shouldn't be used for anything. That hardly makes sense considering it's such a popular class of lens.

Try setting the DA 16-85 or DA 18-135 to f/4 and then zooming. It won't be f/4 for long.

I wasn't commenting on the DA 16-45. If you're trying to shoot wide open with a flash, your aperture changes when you zoom in with a variable aperture zoom. If the flash is in manual, you're changed your exposure.

A small point but those who are using flash, especially in manual mode, likely benefit from a fixed aperture zoom. Also, exposure accuracy is slightly improved with fixed aperture but this would matter more for film when some of these lenses were designed. DSLRs always round to the nearest 1/2 or 1/3 stop (depending on how you set them up) even though a variable aperture zoom has a continuously variable max aperture throughout its zoom range. In the digital age, you can easily adjust in PP.
