Hi,

Anyone knows if any of the 150 -600 s will be available one day for the K mount.

I know the initial announcements did not include Pentax but I have hope they would change their mind and introduce a K mount version later on ( hopefully this year ).

Do you think there is a chance this happens?

Thanks!
 
Wait until the FF hits the shelves. You may see some interesting things happening at or around that point in time. At least I really hope so. I suppose one camera body is not going to have that significant an impact on the total user base. But it may well get the third-party manufacturers paying more attention to the K-mount again. The problem is they need a certain volume of sales to warrant retooling. You'd think the K-3 would be giving them more customers interested in just these types of lenses. Heck even Pentax themselves have released a long K-mount zoom for the first time in over a decade! There must be a market!

There is always a chance, but in this case it is an extremely small chance, I think.

Too bad - both lenses ( all three if you count the Sigma variations) appear to be quite decent for the prices asked.
 
I am a bit pessimistic after reading below:

Slim at best, and unlikely realistically. Both companies are pretty much committed like Tokina to only make lenses they can be assured will sell in sufficient quantities to make money. Tamron supported us for awhile and I am pretty sure Sigma lost money on Pentax mount lenses, the pro ones at least, for quite awhile. I don't think it is likely unless Ricoh-Pentax can get their market share above 10%. Which I doubt because Sony is the 800 lb gorilla in the camera market regardless of their share so they are a more likely customer than Pentax. If Pentax wants to make more money they need to license the 150-450 to Tokina and maybe the 70-200/2.8 also. But that will probably not happen either.

In my view it's simple business, if Pentax sells enough bodies be it APSC or FF Sigma will take advantage of their market share and produce the lens in the Pentax mount without SR in order to make money, if Pentax can't sell enough bodies they won't, it's as simple as that!

Pentax must therefore increase sales of their bodies

Personnel view,if I was Pentax I would forget Tokina and liaise with Tamron/Sigma that's where the cutting edge stuff is happening!

I read somewhere that it's because of the design.

Seeing as the k mount has an aperture pin. Someone mentioned that they really really really hate it as a design feature.

Taking out SR wouldn't help - they already have the tooling on the production line, and the cost is factored into the price of the lens. It would be more costly for them to take it out than to leave it in, at least for the small production runs required.

Yes, Pentax must sell more bodies. But I wonder how they accomplish it? If coming up with good gear was all it took, they'd be on top of the world already.

Be careful what you wish for. If Pentax was working with Tamron or Sigma, they'd stop offering their own brands in Pentax mount altogether so that they wouldn't compete.
 
Thanks guys for your input. Not much hope really...except to get another body from another brand. I find it surprising as many Pentax shooters have long been waiting for an affordable long lens.

I know Pentax launched the 150-450, but it is more than twice the price of the Tamron & sigma offerings.

A couple of years ago, I had read that Sigma was offering a mount change on some of its lenses ( Contemporary? ). Do you guys think this service could be offered to switch to Pentax mount?

Thanks!

Unfortunately that service is only available for lenses that are already provided in Pentax mount.

It just has to be specifically made for Pentax, and slightly adds to the cost. Parts of the barrel have to be modified too, perhaps even some mechanisms, which would be different than for Nikon F.

I wish I knew why they won't make it. I would love this lens for my collection.

This was just what another user wrote. As usual people get their information from the dark places of the Internet.
 
Yet, for the price of the Pentax 150-450mm one easily buys the Tamron 150-600mm PLUS a Nikon D7200. I know the build quality of the Pentax should be better according to existing reviews, but, all in all, for non-pro wildlife and action shooters, there is now a tempting reason to step into Nikonland.

But that would only get you a Tamron and a Nikon. ;)

Based on price alone I think it is a decent point. At f/6.3 the Tamron or Sigma would be a bit on the slow side for action and I've read the Tamron is pretty good only out to about 450mm in any case. So it boils down to price point for a consumer grade super zoom. The Sigma might be anpother matter since I've seen some pretty good results from it posted. To get better quality it always costs a lot more with lenses but the TP lenses give a cost effective alternative and I miss that with Pentax brand in the super-zoom catagory. It isn't a big part of what I do though so more of an academic question than anything else.

That's what I did, I've got a three lens Nikon kit, 18-105mm VR, 70-300mm VR, and the Tamron together with a S/H D7100, that covers me from 24-900mm!(35mm terms) all for 1722 euros.

It's not such an "only" let me assure you!

I still think the K3 is the bees knees however.

Second hand prices should not be compared with MSRPs. And it's not the same covering that range with consumer-level products, or with high-end ones.

The problem with simply accepting what those manufacturers give you is that it will limit your choices, and those of everybody else in the long term. Sigma is in a somewhat ambiguous position on this. On the one hand, it suits them to support fewer mounts as this will result in oligopoly and rising prices, meaning Sigma can also raise prices and profits accordingly.

However, this will also make customers less likely to explore the wider field, in which Sigma's own SLR cameras are found. If Pentax and Sony leave SLR-land, then in terms of lens availability, Sigma's cameras will look like even more of a hobby business.
 
Pentax is not competing against Sigma and Tamron. They are competing against Canon and Nikon. Canon and Nikon already have lenses in this range that cost 2x what Sigma and Tamron have and are right in the range of what the 150-450 costs. Pentax is now in the ballgame. The camera makers generally keep their long tele zooms down in the 2.5x to 3x FL range because you can always build a better zoom with that range than you can with a zoom in the 4x or higher ratio. And I am a guy who has used a lot of Sigma teles and zooms over the years (and still do). Sigma and Tamron realize that to compete with the camera makers their tele zooms have to have a lot more bells and whistles than the OEMs even at half the price to compete otherwise everyone would just buy the OEM zooms. Even at 2x the price I bet the Canon 100-400 II will outsell either of the 3rd party zooms in their camera mount.
