I mean, even w/o those upcoming lenses, we have a good selections of tele-lenses already. Much more to choose from, then 4/3 users have.

Hopefully, it won't be screwdrive type - as long as the focusing is in the lens, I think it will be a great addition. Actually, anything will be a great addition. :-)

Can you provide a link to verify the tamron release? I'd like to read more about this.

People, what's it all about the tele lens ptoblems with Pentax systems? I just went to online base of local optical stores and that's what I can get for my Pentax right away:
Sigma 100-300
Tamron 70-300
Pentax 75-300
Sigma 70-300
Sigma 28-300
Tamron 28-300
Sigma 135-400
Pentax FA* 400
Sigma 80-400
Sigma 170-500
Sigma 50-500

Not mentioning those, which have 250 or 200mm at the far side. Isn't it more then enough?
And I even can add seme unusual options like Russian lens Rubinar 1000/8, which WILL work with K10D (manual focus).
The problem isn't finding long lenses. It's finding long, fast, good lenses at reasonable price. I'm not sure about the FA* 400, but everything else in the list is slow. Granted, most people don't need a constant F2.8 lens, but when you *do* need one, there is just no substitute. Also, any used, fast, long glass is selling for way higher than the same lenses in other mounts.

The Sigma 100-300 is about the closest we can get to a good, fast lens for sports and wildlife right now. But, like I mentioned, it is not fast. That last stop makes a big difference at dusk and dawn (when animals are out) and night or indoor games. As for fast, long primes, there are none in the list. This is even more critical because they are usually easier to use and carry and most of the time work better with tele-extenders.

So, that's what all the commotion is about. Frankly, I'm not too worried right now because I personally don't use long lenses that much right now. I don't shoot sports and I don't get out on wildlife shoots nearly enough. But, if I did need them, I would be hurting.

Anyway, that's my opinion. I hope the primes are released early this year so that we don't have this problem much longer. Even with those lenses out, it will at least cover the long end well enough for most people.

I think a very easy way to add "cheap" Teles out in the market would be to produce a set of mirror lenses: 300/5.6, 500-600/8 (note, Sigma once made a 600/4.5 mirror lens) a 1000/11 and a 2000/13.

No? Ah you're not happy with that? Geeez... you will never be happy will you?

In fact I of course agree, they need to come with Tele lenses. They will of course come first with "normal ones" 200/2.8 and 300/4 but they will have to provide faster/longer ones as well. I think Hoya giving cash now should help them quite well when/if factory problems are solved.

Nope

The Sigma 80-400mm is not made in Pentax mount. This BTW is part of the "problem" for some of us... third-party lenses available for other mounts are not available to us.

The rest of the lenses you mentioned, including some good glass like the fantastic Sigma 100-300mm f/4, are all slow.

And if you can get a Pentax FA* 400mm "right away" then you are quite lucky. FA* glass, in fact most FA glass, is not that easy to get hold of.

The problem is as ncallender said... no long and fast glass which is both available and affordable. Or, some might argue, just available. The best you can do in the current range is the 50-135mm f/2.8, which isn't very long. Yes it's a 70-200mm "substitute", but thing is a lot of people would quite like the coverage of a 70-200mm f/2.8 on digital too... something offered by Canon and Nikon and not only the "big two" but Sony as well. There are also no long primes in the current line-up... long and fast primes are offered by every other system and yes that includes Four Thirds.

No one would argue that having long and fast glass is a matter of life or death. We can all get by without it, but the fact that every other system bar Pentax has it is a bit disappointing. There are of course good reasons for this, and it is perfectly understandable that Pentax chooses to concentrate on other areas of their system rather than expensive long glass which few of us would want. No argument there. But the fact remains that these lenses are not available. So for those of us who would like such lenses there are not "more than enough" choices...

I'm definitely not sure why you think we have much more choice than Four Thirds users, who have the following...
Olympus ED 150mm f/2.0
Olympus 300mm f/2.8 ED
Olympus 35-100mm f/2.0 ED
Olympus 40-150mm f/4.0-5.6 ED
Olympus 50-200mm f/2.8-3.5
Olympus ZUIKO DIGITAL ED 50-200mm F2.8-3.5 SWD (actually announced; not rumoured).
Olympus ZUIKO DIGITAL ED 70-300mm f/4.0-5.6
Olympus 90-250mm f/2.8 ED
Sigma 50-500mm f/4-6.3 APO EX DG HSM (Olympus Four Thirds Fit)
Sigma 135-400mm f/4.5-5.6 DG APO Ashpherical (Four Thirds Fit)
Sigma 55-200mm f/4-5.6 DC (Olympus Four Thirds Fit)
Sigma 300-800mm f/5.6 EX DG HSM (Four Thirds AF)

Compared to what's available for Pentax I can't say Olympus is exactly lacking in good long glass. It might be expensive, but it's there if you want it. Pentax's dSLR system is a very good one, which is why I choose to use it rather than any other, but the fact remains that compared to other systems (not just the big two but Sony and Olympus too) it is lacking in long fast lenses. It's not the end of the world, but it is true.

Sorry for getting off topic but you asked what the tele lens issue is all about... hope that's answered it

Odd... I thought there was more. Guess it's playing tricks on me too Anyway there is that 300mm f/2.8, and of course the 70-200mm f/2.8. There is also the 135mm f/1.8, and the 135mm f/2.8 STF portrait lens. The 500mm mirror lens may be silly, but it's still a long lens within the Sony system... and while it's obviously slow, it's also quite a bit smaller and lighter than the alternative for getting such a length (the Bigma)... so it has its purpose. And if we were to move on to third-party lenses, the Tamron 180mm f/3.5 Macro is available for Sony (but not Pentax).

Their selection is not very impressive, but for long and fast glass it still beats Pentax's offerings.

Well, the other guys have said it all, really. Some of us have a need for fast/semi-fast telephoto lenses.

Sony has made it known that they'd be making more lenses available in the short term, so I guess Alpha users need not worry about the current offerings by Sony. As to what price those lenses will be, though...

I'm curious, though, that the third-party lens makers are still hesitant to release their fast telephoto lenses for the K-mount. I would have think that Pentax cleaned and still continues to clean up following the successful K10D and K100D/Super. It would even help them to make available lenses that fill a gap currently unaddressed by Pentax. Hmm...

Vinzer - yeah, I don't get why simga and tamron aren't jumping at the opportunity to get in on the action. Well, actually since tamron has ties to sony, I can understand they would rather ignore the pentax system instead of encouraging it. But sigma? That's crazy. I think they are rushing to get HSM support in the long glass and it's proven more difficult than thought... oh well.

As for the olympus system, of all, they are the ones really pushing the long, fast glass segment. Long glass at F2.0? Pro zooms at F2.0? Their glass isn't cheap, but if you need the speed, they've got the best in class for sure.

It's promising that Tamron's official announcement of their forthcoming 70-200mm f/2.8 has it being released for all mounts, including Pentax. Of course their priority will be to make it available for Canon and Nikon users first, but at least they are confirming their intention to make it for K-mount. And hopefully the release of the new bodies and lenses will change the situation and persuade both Tamron and Sigma to take Pentax more seriously.

Screwdriven, so it works with all Pentax AF bodies. The 70-200 makes f/2.8 may be of interrest to 24x36 film users.

ZaphodB, thanks, i got the problem now... Could not undertand it because it's not really an issue for me, I am quite happy with "slow" tele-lenses, which are quite numerous for us...

As for 4/3 system, and those lenses you've mentioned... Lets truncate the list as i did for K-mount lenses - i.e. we'll leave those starting from 300mm. What's left?
Olympus 300mm f/2.8 ED
Olympus ZUIKO DIGITAL ED 70-300mm f/4.0-5.6
Sigma 50-500mm f/4-6.3 APO EX DG HSM (Olympus Four Thirds Fit)
Sigma 135-400mm f/4.5-5.6 DG APO Ashpherical (Four Thirds Fit)
Sigma 300-800mm f/5.6 EX DG HSM (Four Thirds AF)

Only 5 lenses... Not that much, really... And only ONE of them is fast (the first one). Can't honestly call the situation with teles on four thirds better, then ours...
