Here at last! - DA* 60-250
Glad you got it sorted, good to meet you. Hope you made sure they didn't give you the duff one to take back to Spain :D No, mine was safely back in its box before greytop turned up with his duffer. I only took a few test shots with mine, at f4 and 250mm of course, and I was very impressed by it but ...

Can somebody please confirm the minimum focus distance for this lens (at both ends of focal length if it differs)? EM 1.1 metres (either end)

Here at last! - DA* 60-250
Hi folks, I've got mine at last, it was hard waiting all week b4 I could get to the shop but I just didn't fancy it being bounced around in a delivery van so I waited a little longer ! OK I can share a few shots from the 60-250 now, make of them what you will :-) Firstly I felt I should check...

Mine's arrived! :D Very quick tests show (i) it is sharp @250mm 4.0 :D (ii) it does not appear to vignette at any focal length on film bodies (at least based on the viefineder view):D (iii) My K10D has slight back focus issues :( (something I have only suspected so far) - Roll on the new body...

If the new one's over a £1,000 I can't see them dropping the K20D they might even have a cash back on it. If they did drop the K20D though they are in short supply at present and there will be a rush for what's in the dealers. shim

Here at last! - DA* 60-250
If it's significantly smaller as is rumoured then I wonder how the DA* range will sit with it.... a lens with something at the end perhaps :D Dunno but if it is but my Pentax A* 300mm f2.8 is going to look bloody silly :lol: The A*300 f2.8 makes any body look tiny on the back end! :lol: The new b...

Here at last! - DA* 60-250
Hi folks, following on from an earlier post in this thread here's Part II Now some pics using K10D of some more suitable targets for comparison, as these were from a w/e in London. All are handheld, although most are taken with elbows resting on a wall so reasonably well braced imho. There's 7...

Ouch - that's not a terribly pleasant experience. It is indeed a lesson for us all. At least he's got a second body to fall back on (not that that's any consolation really)

16 - 45 and CA and options
Pardon my ignorance here, but I do minimal PP, usually a run through Picasa, although I have Lightroom 1.4. I shoot jpeg, so is CA easily corrected, or can it only be done for raw. Lateral CA is easily corrected by many imaging programs in JPEG, TIF and Raw. What many confuse lateral CA with, is...

Bang for your Buck Staples.?
Hi Graig, welcome. Regarding SRS. There should be a comment box appearing when you proceed filling in the usual things on their website. As long as it isn't shipped yet, you can give a PM. He will sort things out for you, if possible. As for the lenses, there are a lot of good options, around...

Which Telephoto Lens?
Thanks for the reply, few to choose from there then:) Must admit to liking the look of the DA*300 and sure it would be a big improvement over my existing 50-200, is a bit pricy though. Think I will look for a few reviews and sample pics of some of the others you mentioned. Got a bad feeling t...

Which Telephoto Lens?

Which Telephoto Lens?
If you have £450.00 burning a hole in your pocket, here is a quote from Stan's site. The writer is referring to the K version, but is basing his comments on the screw-mount version which is (apart from the mount) identical - as is the M version. "Paul M. Provencher - . . . my impressions of this...

Sigma 18 - 125 @srs
Many thanks John for such an informative reply. Can I ask what you think of the Sigma 18 - 125 that is the subject of this thread ?, do you think it will be as good as the 17 - 70 ?,if so it would be a serious contender for my next lens with that kind of reach. SRS only got them yesterday and have...

Sigma 18 - 125 @srs
DonaldM, not a problem, I would summarise the Pentax 18-250mm as follows. But just to clarify, what I'm saying about Pentax lenses is not loyalty but rather a conclusion arrived at after wasting probably a small fortune on alternative makes. If there's one useful thing I could possibly tell anyone i...
