New lenses announced - a bit disappointed...

It's to match 35mm equivalent. So they're focal lengths back when
ppl still used film (or use full frame). They're not exact because
of the optical formulas, I assume because they work better.

Well the spec. says 60-250/4, which makes it a 90-375mm equivalent. A bit closer to 100-400mm but I guess it's not really a big difference. It must be the optical specifications that brings us these curious focal lengths. Lets just hope the quality is stunning :-)

sense if it were 50-260(265). The DA16-50 is a 24-75 FOV equivalent

50-250 at 75-375 FOV equivalent on film is a bit of an odd bod.

Sorry, yes, my bad.

Oh, I WANT that 50-135 f2.8 lens. Hmmm, March 2007. Our 25th wedding anniversary is in April. Wonder if I can stretch 'Silver Anniversary' to mean 'Gold-band-and-glass Anniversary'?

Way to go Pentax!!

Anyone care to estimate a best-case-scenario price list on these DA* lenses for europe??

Would be useful for budgeting purposes... or, just as usefully, maybe as a reality check on my wishful thinking ;-)

Cheers :)

After buying 5 new Pentax lenses in the last 12 months I thought I could coast a bit this year and "simply" buy a K10D. I have to somehow convince my wife that it is a good idea. She thinks my D is a new camera. These lenses however are going to be a real problem. I will most likely get the 16-50 as soon as possible. I use the 16-45 for more than half of my total shots so that is a natural. I was really hoping for a prime tele in the 300mm or 400mm area. I'm not sure how big a market prime tele's would be for Pentax.

The big question is do I sell my 16-45? Do you think I'll get a good return or should I keep it since I will have 2 bodies?

Hi Ivan,
That's good, but that "golden" ring looks cheap!
Yeah, it's a bit over-the-top. For me, the coolest thing would be to make the thicker ring green and the thin one near the mount gold.

All this gold reminds me of my brother-in-law's mom's special edition Cadilac with gold spoked wheels and gold trim everywhere...

This is fabulous. * lenses! 2.8 ED IF! Ultrasonic motors! This is great. Count me in. That 50 - 135 is in my future, bank account willing.

We stay in the game.

Between this news and the K10D, I can see I will be doing some upgrading...

...black, black, black!

Please Pentax, make them both red or something other than that
green/gold combo. It just doesn't look right to me. Or it is just
me?

I believe they have used the 645-lenses as model for the new DA* series. Just look at the similarities in this shot:

Am I alone to not understand the range of the 60-250 ?
I have been puzzled by it all along. Pentax first announced this as a "high performance telezoom." But high quality zooms usually have a range of 3x or less. This one is more than 4x.

I want tripod collars on both the 50-135 and the 60-250. I can't imagine using my current 70-200/2.8 without the collar, so why would I used the 50-135 this way? And the 60-250 is just ridiculous to not have a collar.

I may have to reconsider my plans with these two lenses. I thought the 50-135 was a sure thing. Now I am not too sure.
 
That'll be my next and probably only purchase for a while. Don't really need any tele lens for now, and I'm all ready for this new big baby :D

Thanks for the great news btw.

Cheers,

I thought they'd put tripod collars on the two tele zoom lenses, but don't seem to be there from that photo...

It's the weight of the lens when used on a tripod cantilevering out from the lens mount that worries me. I never liked the idea of the FA300 without a collar. I simply would not hang that much weight without a collar. I think I will forget about any plans to buy the 60-250, and maybe even the 50-135 if they have no collars. Dumb. Really dumb. And I was only planning on buying the 50-135 (didn't think the 60-250 was real). I like the DA16-45 well enough to keep it. Now I am a bit dissallutioned by Pentax's weird lens decisions.

if they want to keep costs down, they can sell the collar as an optional accessory. But they should make provisions for one to be used. For any kind of action shooting, mounting that long lens on camera, then camera on tripod (or monopod) will make it all very unbalanced. NOT GOOD!

Bah! I was so happy to see the pictures, then became sad so quickly. Why do they do this to us? They need to have an outsider in their R&D team to keep them from becoming to much like Pentax. (whatever that means??) First, no AA support, then no onboard wireless, now no tripod collars on premium lenses.

NO Tripod Mount, not even on the bigest of them. The Tokina 50-135 has one, Pentax could shorten the zoom ring or something and put one in there. It is a MAJOR disapointment that the bigger-range zooms do not have this. BIG problem, MAJOR shortfall/overlook!!!
This same problem was the Number 1 Complaint of the 300mm F4.5 FA*

Comeon pentax, you come out with these HIGH Quality lenses without all the features they should have.

(For thoes who do not like tripod-mounts on lens, they could make it removable for all worlds to be satisfied, I know I dont always like having it on there, and thats a disadvantages of the FA* 80-200mm F2.8)

Oh my LBA goodness! The 16-50 and 50-135 are just what I was hoping for most of all! Fits in nicely with my plans to have certain primes but cover the low end with the 16-50, all 2.8 or faster (for the primes).

That big ole zoom though, might wait to see what Pentax has in store on the 300mm prime end of things, or a 200mm macro would suite me just fine and slap on the 1.4 tele converter if I need to catch an occasional bird far away...

Exciting news!
