The Ricoh 80-160mm patent is interesting. I had wondered if Ricoh was going to start updating the classic FA 645 lenses to current specs, so it looks like they may well do it. Running the 80-160mm page through Google translate, it refers to the lens in one diagram caption as the "80-160mm f/4.5 SR". Elsewhere the translation says "it is an object of the invention to obtain excellent optical performance by correcting various aberrations such as coma when it is equipped with a vibration reduction function". So stabilization is in the mix.

If the rumor is accurate, the coming 28-45mm is a stabilized lens, to go along with the excellent 90mm Macro. But the rumor also specs the 28-45mm as a DA rather than D-FA; along with the discontinuation of the D-FA 25mm, this leads me to suspect that future designs will lock further into the 44x33 sensor format.

Either way, it's starting to look more promising that after some time we're going to have a versatile set of modern-coated, stabilized optics to go with the 645 body lineup. If Ricoh can step up the introduction of these new lenses, that will help the Pentax 645 system a lot in the marketplace...

Interestingly, the patent link lists the new 80-160mm lens as D FA and SR; perhaps DA design is limited to the very wides.

Both the 28-45mm & 80-160mm are excellent ranges for the D and the Z. I could probably replace the 25mm without feeling I've lost that much on the wide end. I've found the 33-55mm to be satisfactory for mst of my wide angle needs. I might feel differently if I shot interiors.

That 28-45 would be nice to have... I wonder how it will be priced? Surely somewhere between the 25mm and the 55mm price points..

I'm betting closer to the price of the comparable Hasselblad zoom than the 55mm prime, the Hasselblad 35-90mm runs about $8000 USD new. No doubt it my mind it would cost more than the 25mm prime. A pretty sweet lens though!

The new Phase One 40-80 zoom is $8995, but is has a leaf shutter and a premium price brand name, so I would expect the Pentax to be a bit cheaper, but higher than their 25 and 90 lenses since it is, well, more than one lens!

I don't really follow the logic of the zoom being more expensive than the 25 and 55. My feeling is that it will be between the two - closer to the price of the 25but still cheaper.

good zooms are harder to make than primes - especially slow primes and the reality is that most of Pentax's primes are slow. I'm betting on $7-9K by the time it hits the stores.

I hope that being a new design and slower that it is edge to edge sharp with little to no field curvature and sharp wide open.

If it is all those things then it will be worth a premium price of over 5k.

What a message we are sending to Pentax. They will charge as much as people are prepared to pay and on a Pentax forum, we are talking it up! I'll keep hoping for around the equivalent of £2k. It shouldn't be harder to make than the 25 f/4, and will most likely have some compromises made to make the optical formula to work.

What you are saying is that for a cheaper price you are prepared to accept some compromises.

I am saying that I don't want any compromises and are prepared to pay for it.

Two different requirements.
