Time for a new DSLR sensor??
Funnily enough, only today I was reading an old interview with Ross Walker, son of Peter, the founder of Quad. Quad is an interesting choice to discuss, as it has parallels with old discussions on the relative merits of German as opposed to Japanese lenses. The Quad part is that if you look at...

All the Pentax DSLRs to date use the same sensor, and all offer a range of modes from fully manual to fully auto. The D has the best feature set, but the slowest buffer. Basically, buy whatever is available at a nice price. The kit lenses are quite good, and good value. Worth getting if you ...

I think John means we can't predict with certainty what the future holds, but plenty of people are guessing! Pentax themselves have said that they will bring out a D645 next year, and a successor to the D in the autumn - in other words a more professionally-oriented body than the current offering...

The obvious answer to that question is that your current lenses and most of your accessories will work perfectly with a current Pentax DSLR. The only real drawback to the APS-C sensor is that moderate 35mm wide-angle lenses of around 28mm focal length, are not really wide-angle at all and you need ...

Nikon has stated publicly that they're not building a full-frame sensor, Pentax is putting out lots of lenses for the smaller sensor. Canon has full frame cameras, for a lot of money, but they too have smaller sensors in some of their cameras, and they make lenses for them. If you're really into...

First, don't believe all you read about Pentax and focussing. Very few Pentax users complain about focussing, and it's really only an issue if you shoot sports. Second, there is no such thing as a good .66 tele-adapter. You'll just have to get used to the multiplier effect, and fork out for a n...

Thank you for all the replies. I must admit, I prefer the looks of the DS to the cannon. I just wish that Pentax made a full frame sensor but saying that, look at the price of such a camera. There's one thing that was not mentioned, the filters. Apart from the UV and say the polarised, do you rea...

SLR question - *istD or *istDS2?
The same chip is used in all the Pentax DSLRs, so I'm surprised at the assertion that image quality would be better on later models than on the D. I do not believe there is any basis for that claim at all. The D is a better-specc'd body than its successors, except for one thing - later bodies ca...

Lens Error
George - settle! (although your point is salient and made with some wit :D) First move would be to try another lens. If the fault is still apparent then the body is suspect, otherwise, the first lens. I would try cleaning the contacts on body and lens with a clean dry tissue.

OK-O am a relatively new digital pro, using two 1st DS. Scared stiff of cleaning ccds, I buy a new body for using with different lenses, to avoid the need to changing lenses. But there comes a limit and I now see evidence of dust on the ccds. How do I clean. I have read long, complicated and scary r...

Avoid dusty places, if you can, and use a strong blower to blow the dust away. Pure compressed air is what I use. In two years I haven't had to resort to wiping sensors. Take care to ensure that any canned air you use doesn't contain gunk in the can. G

I know it's no recommended but... I just blow on it to remove any loose dust then use one of those lens cleaning pens. No problem. The glass covering the ccd is quite tough for the reason of cleaning. Don't be scared, just clean it.

You can buy kits for sensor cleaning. Most dust can be blown off with a bulb-type blower, but actually touching the glass over the sensor means you need to concentrate and be very careful.

If I can't blow it off with a "Rocket Blower" (never, ever blow with your mouth!!), then I have to clean properly. That involves using Eclipse fluid and PecPads on the end of a piece of flat plastic. One drop of Eclipse, wipe across the CCD and that's clean (may need to do it twice). The coati...

So best to use a power supply when cleaning. I am going to get a power supply for my DS. I am looking around for a good 6,5 volt power supply which will be cheaper then a original pentax unit.

Folks, I'm way out of my depth here, but thought I'd add a small caution that I've just read in Paul Comon's book on Spotmatics. He talks about how much he likes canned compressed air, but cautions against spraying with the can off-vertical. Seems the propellant which is heavier that air and ...

Most camera makers suggest that you do NOT use canned air spray. A simple bulb-blower is a lot safer.

Sue and i have had our Pentax *istDs cameras for almost a year now, with no signs that any cleaning is needed. What sort of time scale are we talking about before cleaning could become an issue? :?:

Gravity doesn't necessarily help :( CCD are, by definition, charged (Charge Coupled Device) and hence dust tends to stick by static. Initially the dust is hard to notice, especially if you take images of highly detailed object. The best way to check a CCD for dust is this: * Put camera in MF mo...
