Sigma 70-200mm or wait for Pentax 60-250mm

I have been looking for a fast telephoto lens for my K10D, but I am undecided if I should get a Sigma 70-200mm F2.8 now or wait for the Pentax upcoming 60-250mm F4

How much is the Sigma worth anyway ?

I know there is the new Pentax 50-135mm F2.8, but the telephoto range is a bit lacking compared to the 200mm of the Sigma.

Can someone please comment and help me decide on what to do?

I have the Sigma (an earlier non DG version) and it is a very fine lens. The Pentax FA*80-200 is still better, but at a much higher price. Both lenses are very scarce. The Pentax is not made any longer, and when they show up for sale they go for exceedingly high prices.

The Sigma is apparently out of production for Pentax mount also. The supposion is that Sigma is waiting for the Pentax SDM lenses to be released, so they can reverse engineer the system, but who knows. That leaves the used market. If you see one, snap it up, because it won't be available very long.

The new DA* 60-250 is a big question mark. It is not available yet and no one has seen any sample images from it yet. The big drawback for me is f4.0 vs f2.8. A lot of my work requires the f2.8 lens.

Thanks for the info, I know that the coming 60-250mm is F4, but how good is the Sigma wide open? The Pentax should be quite usable at F4 once released.

How much do you think a second hand Sigma 70-200mm is worth nowadays?

Don't get me wrong, I switched from Canon to Pentax, I have absolutely no regrets, I love Pentax gear, but if there is one thing I miss is USM!

So be it HSM from Sigma, or SDM - from now on, I'm waiting for those!

So for what it's worth, (when it comes to the the original question) - I think I'm waiting for Sigma to reverse engineer the HSM on 70-200mm, only due to the fact of 2.8 aperture. Actually rather surprised that Pentax does not have 70-200 or 80-200mm in f2.8 in the works, this is probably one of the most widely used range... So somehow f4 just not going to to cut for me

Regards,
D

But do you prefer the SDM / HSM / USM for the faster focusing or for their silent operation? Cause niose doesnt bother me that much, but if such lenses are much faster focusing than I could wait and save for them.

I need some unbiased reports on the new 16-50mm SDM zoom from user who have both a K10D and a K100D. Or if possible a K10D with SDM enabled and disabled.

For the focusing speed. Noise does not bother me either, the only time noise could make a "huge" difference - closup macros, and still, should be using manual focus on those anyway.

USM was more than "noticeably" faster, I would say "instant" focus, point, half press and shoot, specially great when tracking moving objects.

Dieni,

My experience with lenses is fairly extensive. If you have access to a Sigma 70-200 2.8 (non macro version preferrably) consider purchasing it.

I purchased this lens in December and have not regretted moving away from Pentax in this focal length. It is an outstandig lens even wide open and produces consistantly outstanding images. Price is roughly 1000.00 now since just as sthe lens was going out of production the price (due to glass prices) went up 20%. CA and PF are non existant so far and contrast is excellent. The color shift is slightly cooler than Pentax but that shift is easily corrected in CS2 with a touch of red and magenta.

The Pentax 80 200 2.8 is great if your budget wants a used lens at $2K.

The newer DA* zooms will be fine but I suspect (know) that they will demonstrate CA at wide angles and at contrast zones. They will be superior lenses, yet not perfect.

If you feel that you want a little reach with a little less speed I can also support the Sigma EX DG 100-300 f4. IT too is an outstanding lens with no notbale flaws. It is sharp wide open.

Before you take anyones advice though... make sure that you knw their experience and background in order to get the most out of their comments.

Best of luck in your decision.

Stephen

Thanks to everyone for the help, I really appreciate your views.

Well I have decided to for the lens, if I then decide to get one of the newer SDM lenses, I shouldnt lose to much money on selling it.

I have also a Tamron 1.4x and 2x AF teleconverters and the Pentax 1.7x AF tc which all can be combined with this lens.

The Sigma 70-200 is still damn sharp wide open, I have the DG version. The newer 70-200 Macro which is available for Canon/Nikon/Sigma now isn't as sharp by all accounts.

Just buy the 60-250mm DA* f/4.0 SDM!!!

I purchased this gem about 3 months ago. I was a firm believer in the smc Pentax F 70-210mm f/4-5.6 ED...I still believe...but the 60-250mm f/4.0 SDM takes you to a new level!!! Yes you can get an f/2.8 for slightly less and it must be an off-brand. Do your homework & weigh your averages...the 60-250mm f/4.0 SDM wins hands down. Considering the target audience...stop complaining and save your pennies...I did :-) Check out...

Take care and I'll be looking for you :-)

I see the last post was from August 2007--it's a good thing the original poster didn't wait! It would've been about another 20 months!

That is until you need f/2.8 but whatever works. I really wonder why Sigma pulled the plug on the 70-200 f/2.8 for pentax and came out with a OS version for almost double the price.

Thing is, its still available for other mounts or are they simply clearing remainder stock.

My Sigma 70-200mm f/2.8 with OS, HSM and the works, is due in store here in Brisbane on or about the 20th of this month. And about time too....

Has anyone from overseas got their hands on one yet? Any comments? Any pics?

I'll post some once I get the lens and have a chance to put it through its paces.

OK - I give in.... what date? Today is the 11th August 2010. The lens is due in on or about the 20th. It will be one of the first batch to arrive in Australia. I'm referring to the new lens - the one with the OS (Optical Stabilisation). Not the older Sigma 70-200

This thread originated back in 2007, but the last few posts were from 2 or 3 weeks ago.

What am I missing here?
