Horrible purple cast, not a new species of robin
Whichever way you look at it, it's caused by chromatic abberations. This is the same effect as a prism splitting light into various colours and represents an inability of the lens and/or the sensor to deal with all wavelengths (colours) at the same point. Those of us who wear Zeiss Umbramatic gl...

Horrible purple cast, not a new species of robin
As you can see in my shot, the fringe is purple, and all the way round the robin. PS - note to Mannesty. Did you ever notice anything like this with, ahem, your old 400mm Sigma lens? ;) Sorry Chris, only just caught up with this topic. Firstly, your purple fringing issue looks less like lens...

Horrible purple cast, not a new species of robin
Well it still sounds to me like a Foveon type sensor (with improved low-light performance), is the way forward.......perhaps for a 14+MP K1D!

Horrible purple cast, not a new species of robin
Found this detailed explanation of CA and Purple Fringing. http://www.vanwalree.com/optics/chromatic.html#ref14 Near the bottom of the page it deals with achromatic lenses and the purple and green fringing ( both both of which are evident in ChrisA's "cropped top robin" photo). Coul...

645D Fully Functional
Ben, Is this a full redesigned sustem or just the embodiment of the 'mock-up' which looked to be simply the 645 with an LCD on the back. If Pentax have actually designed an medium format digital system with interchangeable viewfinders and some 'out of the box' thinking then it could do really ...

645D Fully Functional
Are you saying that you would like to see a rotating back (or sensor) so that you can go from portrait to landscape without moving the camera? G YES!!!!!! Rotating back! That's why I bought the RB67, and I'd LOVE to see a 645D with a revolving back. That way, you can put it on a tripod and n...

Well, looks like it is getting closer to a reality, as "Chasseur d'Images" Magazine April 2007 issue is showing it. This is the number "1" Photography magazine in Europe. This is the classic marketing procedure I have seen it in the past with other camera introductions. Kodak 31....

645D shown in April Issue of "Chasseur d'Images" Magazine
As far as I can see this is just the 645IIn with a sensor and LCD,....I can tell you now that it WILL be very cost effective because other than a good price it has little to offer,.....just a poor mans 'Blad H2/ H3 (which is a 39 or 45 meg system) without even the limited adaptability. Quite a lo...

Selection K10 images taken in Wales Saturday 24th
Your sensor needs cleaning Pete. Top left and top right of the 'line of trees' shot shows evidence (little round 'n grey blobs) of dust. To me, these latest pics are rather ordinary, more like a quick grab record shot, but nothing much worth recording. You've produced better shots than these i...

New Senor Technology for Sony, Pentax and Nikon
From what I've read of the new Sony there are some that already are available (or will be very soon): The fiscal year in Japan ends March 31st, that's also why shareholders are informed about new opportunities, markets and products. Sony Japan just announced some exciting news about their DSL...

New Senor Technology for Sony, Pentax and Nikon
At last some intelligent thinking 'out of the box'.... Hopefully this will now lead makers away from the 35mm SLR with sensor and over to real digital imaging systems. Additionally, it will now be very interesting to see what Pentax cmes up with next as this anouncement effectively renders the...

Oh dear... here we go (again)... Seem like we have more of the "If only the camera designers would think out of the box then I'd start making decent images with their gear" kind of thinking. Yes, new sensor technology is interesting, but only up to a point :roll: Let's not squabbl...
