Cleaning of kit
Anvh I have been told not to use dish washing liquids on glass, because it leaves a smear or film to make dishes sparkling clean, the old style soaps are produced from fat, so I would not want to put any of these on my cameras or lenses. I love clean water and soft cloth it may not be the best cl...

Sharpness? resolution? contrast?
What property of the lens defines resolution? What I can see is two lenses that can direct the light so that the same item is described by the same pixels. At least the demarcation between contrasting areas seems to be well done on both. But for the same pixels one lens can display more informatio...

Weather seals
There are a number of threads where the weather sealing is mentioned. The last one being the "dodgy" non sealed K7 grip. If its sealed, fine. If not why is it an issue? Anyone lost a winder or drive or camera or lens due to moisture ingress? If so, how bad were the conditions. My Sigma 70-200E...

Any good Reason to buy a Pentax?
For P&S I would suggest Panasonic Lumix series ... you have several options ... for maximum zoom range you can check the TZ series ... for a larger than regular sensor, you have the LX series, with the LX3 getting very good reviews ... I have used a FZ5, TZ4, LX2 and now a LX3 ... TZ was the most co...

New Sensors
There has been a lot of activity in Japan about the new generation of sensors which are going to be launched soon. Some famous photographers were invited to speak to all camera manufaturers. I have no inside knowledge of the meeting. I know professional photographers and those who work for Nik...

New Sensors
It`s my guess that this new generation of sensor is based on the one that Kodak introduced a year or so ago. Kodak developed the Bayer pattern over 30 years ago and has been used in most sensors ever since. Essentially you have a pattern of four photosites, 2 sensitive to green light, one to red and...

New Sensors
It`s my guess that this new generation of sensor is based on the one that Kodak introduced a year or so ago. You could be right, the KAF-40000 (that is in the 645D) has the same contacts as the KAF-50100 so they can easier be changed.

I don't see the connection between new sensor technology and interchangability................................ both are good ideas, but unrelated?

New Sensors
I had read about black silicon as well. a new generation of sensor are comming but if already have cameras with perminent sensors in them, we won't be buying a new body just to get a new sensor. If sensors can be changed, the consumers will be upgrading more often. It will be interesting to see what...

New Sensors
The problem with interchangeable sensors, is that, assuming the new sensor is of a higher resolution, the camera then can't process the extra information (per photo) as quickly as it did before, so frame rates would either drop, or the buffer would fill up much more quickly, or both. We can see t...

Interview with Hiroshi Onoda, manager of Pentax Europe.
I'd be very surprised if the camera above the K-7 is FF, I suspect it will be an attempt to close ground with the 7D and D300s, features I personally expect will be (hopefully) AF improvements, 2 card slots (aka 645D) and maybe improved pipeline processing with a new sensor with better high ISO and ...

Interview with Hiroshi Onoda, manager of Pentax Europe.
I think it is unlikely we will see a FF camera in the near future. Especially in the context of the launch of the 645D, which I hope will prove itself to have been an inspired decision by Pentax. Sony do not appear to have been particularly successful or profitable in taking on Canon and Nikon in ...

Interview with Hiroshi Onoda, manager of Pentax Europe.
Over a few years the aps-c sensor would be so good that we would wonder why we would wanted a bigger sensor/camera to begin with :wink: In the end the 3/4th sensor of Panasonic and Olympus might even be the one that hold out the longest. :roll:

Interview with Hiroshi Onoda, manager of Pentax Europe.
I think the most damning thing for Pentax is that regardless of what Pentax want, FF sensors will reduce in price over time and then they will impact on high end APS C cameras. There will be a time when Canon, Nikon & Sony will produce a FF camera that is at the $1,500 mark of todays high end APS C ...

Interview with Hiroshi Onoda, manager of Pentax Europe.
I'm not so sure, because it is related to the quality needed by the market. FF sensors may well become cheaper, but so will APS-C. They may well become better, but so will APS-C. So when the noise level is irrelevant, the pixel count as high as anyone needs for any purpose and all this can be ...

I'm not so sure, because it is related to the quality needed by the market. FF sensors may well become cheaper, but so will APS-C. Yes, you are correct, John, but my point is, at the price point at which advanced amateurs and semi pros work at is at a level where the best IQ they can get at the hotl...
