Seeing as predominately I shoot landscape images a fast f2.8 aperture lens isn't needed for me so I'm rather interested in this lens if it comes to fruition. Anybody know if it'll be weather sealed, have a tripod foot on it and also what it'll sell for roughly?!

As even the "kit" lenses are wr now, it's hard to imagine it wouldn't be,
and even an f4 70-200mm will be a fairly hefty lump, so I would imagine a tripod foot will be on it.
Price wise, I would be surprised if it isn't around the Da* 300mm price point.

Its not something I've read, I haven't heard anything about it, other than it is in the pipeline, so these are just my musings on it.
I know what i like, If not always why.

I'm not sure an F4 would be that big. Think about the old 70-210 F4- 5.6.
The main thing would be the weight. And then again, neither the DA or FA versions of the 200/2.8 had a tripod mount.

According to the rumours site it will be based on the Tokina AT-X 70-200mm f/4 which I gather is being released around now: https://www.bhphotovideo.com/c/product/1054592-REG/tokina_at_x_70_200mm_for_4.ht...
No sign of a tripod mount, but the slower lenses didn't usually have one anyhow.
Tokina price: $899, Pentax price, your guess is as good as anyone else's! Weather sealing? If it has Pentax may use it as a justification to add a few more £££ to the list price.

It has been on the road map for a while now, due in the spring but if previous launches are anything to go by then probably later in 2019. Given the direction Pentax lenses are heading I guess this will be another high quality product with WR and the special coatings, and maybe the new faster motor. Maybe we will see a pre-production model at The Photography Show as we did with the new 50mm. Given the weight of the 70-200 f 2.8 I wil definitely be interested seeing the Tokina is half the weight but will I trade it? If I can afford not to I will hang on to it for a while and see.

And Jak, Pentax donít just change the label and double the price, you really get what you pay for in extra performance and quality.

The Nikon Tokina version is quoted at 980g. The specification of the Tokina version is on the B&H link in my previous post, so no need to fully ruminate(?) about it!
Given the Tokina version is only being released next Monday (12th Nov), it would be extremely surprising if the Pentax version had managed to come out before it.

I'm doubtful what JAK says is wholly true: the lens he linked to started production in 2013 (and had a tripod mount as an optional accessory).

I'm sure a five-year-plus old optical design still holds up, but I'd expect Pentax to remove the stabilisation.

(And anyway, according to da internetz, Pentax supposedly copy Tamron designs).

Wasn't my rumour, it was the rumours site rumour! At the end of the day, who knows what can be believed, we'll just have to wait and see. Until its officially announced it can only be guesswork.
As to tripod mounts, Pentax release APS-C lenses to 300mm without one.

Looking at the Tokina one (67mm filter thread), I would guess such a lens would be about the size of the 50-135 DA*. No real need for a tripod mount on that

.

With most of the bokeh and IQ characteristics of that DA* lens due to crop factor. They'll be onto a winner.

And what about the A series 70-210 constant f4? I still have mine (somewhere). Last used on a Pentax Super A with MEII winder to take shots of the Red Arrows performing at the RMCS Graduation Day display (somewhen in the late '90s). Not too heavy as I recall - must look for it.

I'm looking forward to seeing this lens. It should be high quality and a bit more compact than the f/2.8 version; as well as, hopefully, costing a bit less.
Best regards, John

DA*60-250 f4 has one...

Could Pentax not re-engineer the internals of this lens, remove the baffle and update the focussing system to become a D-FA 60-250 f4? All K-mount fans would rejoice.

It's not just a question of removing the baffles. It is not a FF lens cut down to APS with baffles. It was designed as an APS lens. The basic formula might be usable but all the elements would have to be enlarged for FF coverage. It would make it much bigger and heavier. There is also the SDM issue.

As much as I loved my 60-250mm f/4 I recently sold it as it wasn't getting any use with the K-1 (however I have started looking for another)

Saying that the one thing a 70-200mm f/4 would hopefully have over the 60-250mm is internal zoom.

The 60-250 has basically the same motor as the 16-50, 50-135 and the two long lenses. The only problem is that the screw drive conversion does not work on the 60-250.
Ricoh/Pentax have always denied the problem but I doubt they will make more using the same mech.

What SDM issue?
