Don't know where people have come up with ~$1000 as the expected price point for the 560mm. Baseless optimism, presumably. 560mm @ F5.6 means a 100mm entrance pupil, same as 400mm F4 or 300mm F2.8. I predict somewhere around $4000 for this beast. Maybe more.

Poor Kev seems to have had his thread hijacked by Fabien.

Anyways, my advice to OP for his purposes would be DA 35mm F2.4 (or 35mm limited if budget will stretch) plus DA 55-300mm.

The older DA18-250 and its Tamron twin are usually considered better than those Sigmas or any 18-200s. ...

If you don't need that wide a range, consider the DA55-300, very well-liked. ... I also have my F35-70, the smallest zoom Pentax ever made: agile (VERY fast AF), sharp as a bag of primes, and cheap at around US$50.

... Happy hunting!
Bonjour,

Just an echo of what RioRico wrote ... I have the DA 55-300 and it's very capable lens, and I have a F 35-70 which is a super bang for the used lens dollar. It spends a lot of time on the K-5 at the expense of more expensive glass ... and the DA 35 f2.4 is the second overall "time winner" on the K-5. I've never had the pleasure to try a 18-250, but I did have a first generation Sigma 18-200 that I never became fond of ... not sharp at all my copy, and I just sold it off to a student photograph looking for the decent priced lens of this type/category. Just for what it may be worth ... and happy hunting.

Salut, John le Frog

I had a Tamron 28-200 that wasn't bad but was nowhere near the DA18-250. We see from the reviews that the DA18-250 or its Tamron twin are consistently rated better than any other 18-200 or 28-200 or anything else in that range. Even my rather decent PK-A Tokina SD 35-200 doesn't match the DA18-250 optics.

A pretty good suggestion based upon my current lens(es) set(s) and experience. A+, J

IF you need the range then I'd say the Sigma 18-200mm is a decent lens.. I have an earlier gen Sigma 18-200mm and while it is not prime sharp it is still quite sharp (can be cleaned further in post processing). It will more than likely meet your needs as you are admittedly an amateur (like myself 2 years here) and are learning anyways. I find its a really handy walk-around lens.

Even if I got some sharp AF primes in that range, I'd still keep the 18-200 in my bag.. it is too handy.. less swapping lenses.. more shooting. You aren't generating content (yet) for Getty or Corbis so it really isn't a problem that its not the same range as more expensive glass.

That said, for food and other stationary items, you might want a couple primes something like a 35mm or a 50mm with really nice color traits and are super sharp.. the old SMC M's (such as the 50mm f/1.4 or f/1.7) are decent and cheap. Only minus is they are manual-only. However, that might be a plus for you as you will have to learn exposure and focusing this way (instead of setting the K-r to auto-mode and letting it think for you).

I would also recommend a proper flash.. lighting is sooooooooooo important and often neglected when starting off.

Thank you all for your answers!!!

I'm now still hesitating and wondering between 3,......

This one from Pentax Pentax SMC DA 18-135mm F/3.5-5.6 ED AL (IF) DC WR Lens 21977 B&H that I would reckon would work on my K-r(?)......,

this one from Sigma Sigma 18-250mm f/3.5-6.3 DC OS HSM Autofocus Zoom Lens 880-109 and this one from Sigma as well Sigma 18-250mm F3.5-6.3 DC Macro HSM for Pentax K Cameras......

What could be the differences between these last two from Sigma?..... Could it be the sharpness of the picture as mee mentions?.......

And for this one (last link), it seems that it is a new lens not available yet, if I eventually chose that one, when could we expect it to be released?.... (a few weeks or more at the end of the year of later?.....)

There is still also this one Sigma 18-200mm f/3.5-6.3 II DC HSM Lens for Pentax AF 882109 B&H from Sigma.......

These Sigma Lenses mention
"For Pentax K APS-C Cameras Only" or "Note! This lens is only for APS-C / DX sensors (not full frame)." or "Not suitable for 35mm film SLR cameras or for any digital SLR camera with image sensor bigger than APS-C size.", ......would they work on my K-r?.......

Sorry if I am asking stupid questions lol.......

Thank you very much!!!

Kind Regards

Fabien

Yes they will work, the K-r has an APS-C sized sensor.

All Pentax DSLR's have APS-C sensors. Also, looking at the specs, the obvious different is that the new one lacks OS - the in-lens stabilization. No matter, since Pentax offers SR in the body. No idea if the optics are new, but I'm sure Google would be happy to answer that.

Except the 645D, but that's another kettle of fish. Alas, not all APS-C sensors are the same size -- it's a rather loose 'standard'. But any lens meant for either APS-C or FF will cover an APS sensor, no problem.
