She is gorgeous, and as we know both the digital camera and the internet were invented for the sharing of pictures of cats, so well done!
Next Logical Step After *ist DS?
Posted in Pentax Digital SLRs
What do you generally shoot? If you don't need or want ooodles of megapixels or high ISOs, the K10D is still a solid camera. Available on a certain auction site for ~100 - 150 (with an 18-55 it's closer to 150). I'll be selling mine shortly but I already have a buyer. At ISO 100 the K10 remains pretty hard to beat, although its performance at 800 and 1600 leaves a lot to be desired.

Thanks for taking the time to do that Smeggy, that's a very interesting comparison. Like you I enjoy low light photography of dynamic subjects so high ISO performance is important to me, and the higher the better. I have even been known to take my *ist out over my K10D for the extra stop. I think my decision is going to come down to low light and tracking AF performance, if it's enough of a step up from the K5 is might overrule the drop in high ISO.

He doesn't look happy, I think you made the right lens choice here! nice capture.
Pentax FF Dead, Maybe

I Edit: Possibly the Sony EVF does not close the aperture, which must restrict the range to that of the sensor. Don't look at the Sun. --shouldn't really look at the sun though an OVF either, you'll burn a rather more precious sensor if you're not careful!

RAW files have never been totally 100% RAW as a certain amount of processing is needed to make sense of the Bayer grid info and merge it into a full colour image at every pixel site.point of pedantry, that is actually handled by the raw converter, some converters give you a choice of algorithms for de-mosaicing, with some being better than others for high ISO or fine detail rendering. You are correct that some processing is necessary though, the signal from the sensor itself is analogue (a voltage) and must be converted by the A/D converter.
Interesting........

I reckon you would still shave the best part of 100 off the UK price. :)But the UK price drops by at least 85 if you give up your old camera to SRS for example, and I for one have got several of them (if only they'd take more than one!) So I'm another who wouldn't do the Australia import thing.LOL, if he'd take more than one I could buy a K3 in film bodies without having to part with any of the ones I actually like!
Pentax in Las Palmas?
Posted in Lenses for Pentax Cameras
Caveat emptor I was in Gran Canaria a few years ago and got pestered by every dodgy camera shop owner who spotted the Pentax strap around my neck. When I got home I discovered there had been a massive bust of fake kit. My wife did manage to get a good deal on an Optio S4 many years ago, but it took her a whole day to beat the guy into submission to actually sell the camera. It seems the trick in use there was he had one Pentax, one Canon, one Nikon and a massive stock of cheapo knock off crappy things, and he was trying the old bait and switch. It's not worth the hassle.

The big problem with the rear LCD and possibly an EVF is that it uses a different aperture to what you are using on the lens..... so DOF could be miles out. You could have f/1.4 on the lens and LV is using f/11 :shock: This also makes focusing difficult. --not sure where you're going with this one Algi, since the exact same thing is true of an OVF unless you kick the DoF Preview in. Arguably an EVF is better for this, since it can use a longer exposure/higher ISO to capture the DoF Preview image and thus avoid the dark viewfinder associated with that function on an OVF. Don't get me wrong, even having looked through the highly impressive EVFs on recent Olympus's I still wouldn't give up my Pentaprism willingly, I just don't think this is a useful line of argument.

That's a shame really, the new HD limited lenses are getting superb reviews and three of them are already tested on PU. See the pane on the right. The only reservation about the new Ltd lenses is that the application of a new coating , however good it may be, is the occasion for a swingeing increase in the retail price - well over 100. I'm entirely happy to do without the claimed marginal increase in contrast when shooting against the light.they do also have rounded aperture blades, although I admit on the face of it that still doesn't quite justify the price hike. The tests on PU so far show lenses which break the Y-axis on their MTF graphs, but I haven't checked if that's new compared to the SMC versions.
More k-3 images inc ISO 3200

I think it's unrealistic to expect the noise performance to be better than the K5. With 50% more pixels crammed in, no worse will be an impressive achievement in my book.

I hope that's representative, looks like my K10D at about 400!

I don't buy the clam that a FF Pentax camera has to be any or much bigger than a K-5/K-3 I've got several Pentax FF film cameras that while thinner, are not really any bigger width and height than the K-5. Yes I know sensors, LCD screens, etc are thicker than film and that accounts for the bodies being thicker. Even taking into account the extra real estate being used by the EM coils used to implement the sensor stabilisation system wth a bit of juggling I bet a FF camera could be the same size as a K-5/K-3I agree completely here, I certainly don't see why a Pentax 35mm body couldn't be the size of a K10D at the largest. Just because Canon can't or wont produce a sensible sized 35mm body, doesn't mean Pentax wont.
K3 price
Posted in General Photographic Chat
In the past - and past events are no gaurantee of course - SRS have sometimes advertised the mandated list price before release and then actually charged less than this. Fingers crossed it'll settle a bit quite quickly, I really want to stretch to a K-3.

When I lived in Cambridge I had access to the telescopes on the "hill" at the University astronomy department. The larger of the two was roughly a 5000mm f/16. Alas I never managed to get my K10D mounted on it, it was amazing to look through though, particularly good for planetary astronomy. There's something about ~10 tonnes of victorian ironwork which is so finely ballanced that you can move it with one hand.
Uv filter
Posted in General Photographic Chat
Deppends very much on what I'm shooting and which lens, my 80-320 reacts very badly to filters, some of my other lenses don't mind as much. When I do use them, I only use multi-coated filters to minimise their impact on flare resistance.
A decline in DSLR sales threatens camera companies

More people are going to skip more models before upgrading in futureDo many people upgrade every time? I don't know, I've never understood people who do, my point was that whatever proportion of people have previously upgraded most product cycles, that proportion is likely to decrease as they become more and more satisfied with their current model. Personally, I'm currently considering upgrading my K10D to a K-5II or K3, really hoping I can stretch to a K3 since I'm unlikely to upgrade again for at least 5 years.

I'm not sure, but I think this is what happened to my Dad's P30T, he ended up buying a second hand Super Program :(

Thank you for this. Useful info, if a trifle condescending in places. But, I am grateful for the genuine help. Pentax user from 1972 also Bronica.My appologies if my post falls into the condecending category, that was not my intention (quite the oposite in fact), although on re-reading it comes off more clipped than I meant it to.

The best I've ever managed was this: Tamron 300mm f/2.8 SP lens on a K10D, several stacked 3 minute exposures mounted on a Celestron CG-5 equitorial telescope mount.

The issue I foresee is more one of convincing people they need the latest and greatest model. Convincing someone that a K-10D is better than a *ist D by far enough to justify an upgrade was fairly easy. My *istDL2 was less than a year old when I bought the K-10. Convincing someone that the K-3 is better than the K-5 by the same ammount might be harder, and that is only going to get harder as time goes on. More people are going to skip more models before upgrading in future

What does all this speculating matter?.....the main thing is whether it works or not and that you can turn it on or off instead of buying two versions of the same camera! :roll:here here
