Poll - who would £1000 for a full frame K10D?
If you are going to come and post here, please take the trouble to keep up with what is going on in the modern world. This is 2006, not 1906. Pentax have already announced lenses with motors in them that will be available in the first half of next year. http://www.digital.pentax.co.jp/en/lens/r...

Poll - who would £1000 for a full frame K10D?
I think we WILL see several makers having 'full- frame' models in their product inventories,...perhaps there will also be different sizes/shapes of sensors also. I think that the Sony company holds the key to this hypothesis. Trying to see into the future is a "fool's errand", howeve...

Poll - who would £1000 for a full frame K10D?
Incidentally, I understand that the APS sized sensor has already reached a 'max-out' due to the laws of physics and would reqire revolutionary changes of direction to go further in terms of pixel count and resolution. I'd have to disagree with that statement, as technology is sure to progress at the...

For the last few months, I've spent my days in a college classroom. The curriculumn calls for film. using my ist ds2, and my super program together, I've shot digital polaroids, and b+w film. here's what I learned: I've been sloppy in recent years, since switching to digital, releying on softwar...

Reciprocity Failure ?
Well, I can give you a very definative answer and a reason for it, but I don't know how good I am at describing it... I assume you understand that film reciprocity failure occurs because film exposure works on a logarithmic curve (note: same as film characteristic curve). When something is record...

Reciprocity Failure ?
well now that they got dust/moisture sealing on the lenses, I see no reason they can't stir up a little cyclonic windstorm inside the camera with a miniture fan...to cool the sensor and collect the dust.

K10D - I got mine!
Strictly speaking CA is a lens attribute. It will generally be worse in longer lenses. This fault will show regardless of what body the lens is used on. It is a function of the diffraction properties of the different glasses in the elements not being matched correctly and will show uniformly across ...

DON'T BUY PENTAX DIGITAL LENSES!!!
teogin, no need to apologize, you may very well be right - time will tell! Many forum members have expressed a desire for a 'full-frame' DSLR and have speculated as to the specification of a K1D (such an obvious name that Pentax are bound to choose something different!) but it will come. Just l...

DON'T BUY PENTAX DIGITAL LENSES!!!
As I think I said in another thread, neither I nor many amateurs need to produce prints larger than A3 and for that even a 6 MP APS-C sensor is easily sufficient. The size/weight thing also becomes important these days. If you want to attract new people into SLR photography, you have to remember t...

Needs also to get facts right... I believe Nikon have stated they won't be doing FF, the Olympus sensor is smaller than APS-C There is a trend for things to get smaller and smaller, and as some of the others do say, 6MP is adequate for most people's needs (gives satisfactory 10x8 prints), so a...

DON'T BUY PENTAX DIGITAL LENSES!!!
I can't help but agree with everything said so far but I don't discount the possibility of anything. Just look at how prices for technology have tumbled, who would have thought just a few years ago that computers with flat-screen monitors, multi-core processors, gigabytes of dual channel memory and ...

DON'T BUY PENTAX DIGITAL LENSES!!!
Surely the point, Kimbo, is that a bigger sensor will always cost more than a small one, and people always buy on price unless there are very good reasons not to. Personally, I am buying the K10D primarily for speed. The larger sensor is pretty much irrelevant to me; but greater speed justifies ...

Yes George but if a full frame DSLR can be introduced to the market at a similar price to the APS-C models we have today, then most buyers would go for that. Obviously the smaller sensor models will become cheaper still but in today's economy, any sub-£1000 camera is within most people's reach. The...

DON'T BUY PENTAX DIGITAL LENSES. He has a point if only to reiterate what everybody already knows. The new D-FA lenses are not compatible with the old cameras, but everybody buying a new lens is aware of this and won't be buying a digital lens only to be surprised when it deosn't work with their old...

I am surprised by the vitriolic remarks made in this posting, I've never before seen anybody's character questioned on this forum, maybe their judgement, but that's OK, we can always have a disagreement, good debate and end up agreeing to disagree. :P I can see all the points of view here (I don...

Debate is fine, personal attacks are not. The point about lens design is a valid one indeed. Some older lenses are excellent though on digital, others are not so good. To a great extent the arguments about telecentric design are mitigated by the APS-C sensor only using the centre of the field of ...

I would be grateful if anyone of you tells me why the photographic companies have been trying to bring (and they succeeded it) the APS system. I remember the APS film. People didn't support it and after some years they brought it again as a digital solution. I am trying to think why. As all ...

To me it seems strange that we are debating this endlessly :shock: At the time I bought my first film SLR, why did I not go for the 645 system? Would this not be the same today as going for a Full Frame over a APS C? Quality, clarity? Surly I made a very bad choice! This is what this discussi...

The original poster seems to be misinformed on a couple of points. Firstly if you do not use DA lenses on a Pentax digital body then you will be loosing on quality and thats the prime reason to buy them. One of the problems with digital is that the circuits on the sensor chip can cause shadows on...
