Horrible purple cast, not a new species of robin
Just to muddy the waters a bit, here's another extract... from one of the links at the Wikipedia CA page. Longitudinal and lateral chromatic aberration can both give rise to colored edges, but properties are different. Axial color causes fringes all around objects, whereas lateral color only...

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
I'm not sure whether Chris' lens was a DSLR specific lens It isn't. It's a manual-focus Sigma 400mm F5.6 lens, PK/A fit. This one looks identical: http://cgi.ebay.co.uk/Sigma-400mm-F5-6-Telephoto-Pentax-Fit_W0QQitemZ160096599080QQcategoryZ48558QQrdZ1QQcmdZViewItem

Horrible purple cast, not a new species of robin
Question: Has anyone experienced this purple fringing thing with film, rather than digital? Everything I read seems to focus on digital. Just curious. But since taking up SLR photography in 1984 with the Super A and ME Super, and quite a few not-at-all-Pentax-SMC-lenses, I never saw it with ...

Another natural lightingshot(pic of the bunch so far for me)
I'm sorry it felt like punishment. I like this one much better. the reason I mentioned more attention to background is simply this: the brickwork is nice but doesn't work with the pastels and dreamy soft focus effect you got. (both in terms of color and texture...they seem to clash.) now if yo...

How do I add image info to my photos in photoshop
Tried this guys, No joy, I think it is probably saving the image more than once that as affected the Exif info overall. So I've copied the details from the original image using Opanda Software I have just brought. This allows you to edit the Exif file step by step but it is very good and easy...

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...

Caliberate LCD screen with Eye One Display 2 Gadget
Hi folks A few days ago I caliberated my LCD screen with a expensive £169 gadget called Eye One 2 which my cousin purchased from the Focus 2007 show. It did the job Ok on my monitor but I really don't like the colours now. Is this normal ?? The green looks unatural very milky/lightiss grass...

K10D PEF files under Linux. All Ahead Full!
add the cost of ownership to your math. the mac comes with software to edit, organize, create digital content with (truly outstanding package), then add the cost you save by Not having to buy spyware/antivirus software, and the cost of servicing. I think you're caught in the tortise and the hare a...

Selection K10 images taken in Wales Saturday 24th
I guess I just like to post photos that I like and think are not to bad. I completely understand if other folk don't like them but I value opinions and views on what I am doing both wrong and right with may images. These most recent ones lack spark as you have mentioned. I'll keeping looking and...

Selection K10 images taken in Wales Saturday 24th
I actually agree with you both. I suppose they are a bit dull. I want to learn to take good pictures so as for the books I will have a look in the library. I must point out I have seen myself some images posted here that I thought were not very good at all but it's difficult when you learning as ...

Lense Issues
You might be able to fashion a crude adaptor using a Pentax body cap, a Canon back cap and some determination. Unfortunately this will act as an extension tube and you will loose infinity focus. Might be worth a try if you are feeling practical and have a good macro lens in Canon mount, otherwise mo...

Lense Issues
Usually people want to fit Pentax lenses on Canon cameras, thus adding superior glass to a sophisticated body. It doesn't work the other way around because the Canon lens mount is wider than the Pentax K lens mount. You could bodge it, but the lens will be too far forward, and infinity focus wil...

A Guessing Game.
C$7,999.99 Some broken arms, legs, and furniture... A cancelled marriage license... It's not in MY price range, but knowing Pentax, it WILL be the affordable choice. :D When I was with my ex-wife, I purchased a 40th anniversary Cherry Red "Fender" Stratocaster. This was while I w...

A Guessing Game.
Now here's a sly thought...is this an "unofficial" project by the Pentax marketing team to work out the price? :wink: If so, can everyone come back and post a price to match my £999.99? :lol:

The Price is Right
Hey, Chris, what did the rep have to tell you? We had a good meeting - the * lenses were placed on my Pentax display in the shop window for a couple of hours and created a certain amount of interest! I have a large quantity of refurbished product coming in (mainly compacts) but also have secured ...

VPN...What Gives?
The conditions to make that happen much be rather difficult, or is it that some cameras suffer where some may not?? I have tried to reproduce the effect back to when I firs got the K10D, but cannot do so either. Although if I take a long exposure with he lens cap on, there is a significant more ...
