So the link is here
??16-70/4?18-70/4-6?25-350/3.5-6???????? - ???
I tried to searched in Japanese and no Japanese pages pops out. Google translate might help you guys a little bit.
All of the lenses are APS-C.

Well...

I don't see the logic in either a 16-70/4 or 18-70/4-6 in APS-C, since there is already a decent APS-C 17-70 f4 in the catalogue. If they were FF lenses, maybe.

Er 25-350? That's quite the odd number.

If they make the 16-70 WR I'm all for it, it's missing! 18-70 F4-6 sounds really weird and the only thing I can think of is some kind of smallish limitedish setup.

I have a feeling that I've seen the 25-350 on these forums before

Please bear in mind that those numbers are usually "modified" for marketing purposes. So suddenly 25mm becomes 24mm and f/6 becomes f/5.6.

Well, both that lens and the 18-70 could be lenses for fixed lens cameras, then they make some kind of sense.

Very good point, but APS-C for the 25-350? 25mm (or even 24) is a bit too long for an APS-C camera as a walk-around fixed lens camera...

Not that I'm complaining if Pentax is coming out with a 24-350mm superzoom that performs well.

16-70/4 is probably a replacement for DA 17-70/4, and might be WR and use DC motor.
18-70/4-6 sound like a new kit lens with WR and hopefully with DC motor too.

I see a diagram for 15-45/2.8-3.5 lens too.

Agree, 25-350 seems odd for a APS-C lens, and would make more sense for FF.

Well, it would make a nice safari bridge camera or a good way to provide proof for birdwatchers.

Mmm indeed but Canon still did sold (still sells? I dunno) an EF 35-350 which was popular (but soft if I remember well).

None of them covers FF sensor.

From my understanding this can be an alternative to Siggy's 50-500. Not exactly the similar, but probably same ieda?

The problem is that, the focus height of 25-350 is about 14mm, which couldn't cover FF's 21mm. So it is still a APSC lens.
