Sony DSC-F828

I am considering upgrading my 717 to the 828.
Some reviews state this is a very good all-round non-professional camera.
Other say it is well below par and stay away.
Indoor focusing , purple fringing and other odd colour effects are mentioned
as problems.

Can anyone put this into perspective for me?
Stay away or go for it?

What is purple fringing?
Would like to see and example of this.


Thanks
Jon

 

The Sony has purple fringing problem in most cases for sure ... but speaking
of that ... my ED glass also has that problem in EXTREME condition.

F828 is generally a very good cam, I know a wedding photographer that uses
this cam for his 'fun' work ... and his work is darn breathtaking.

But considering the price .. Canon 350D is another option you can look at

As you did not get an answer yet, here is the explanation: purple
fringing is the effect that dark objects outside the center of the image
- say as example dark branches of trees - do not reproduce as dark
branches but have a colored edge - usually purple. This effect is
noticeable if you enlarge quite a lot and if the contrast between
background and object is quite significant as in the example of dark
tree branches or edges of houses or similar objects.
It has to do with the dispersion of the top layer glass which protects
the image sensor and the angle of the imcoming light from the camera
lens. Usually not really a problem unless you search for it. Sony in
general is quite good but - if I would spend about US$800+ for a Sony
828, I would add another US$150-200 and get a Nikon D70 with lens on
offer...better image quality and a better investment for the future.

I've been informed that this was cleared up after the initial run and isn't
a problem anymore. I've no evidence of this though, but I have seen the
results from a few late model ones and haven't seen anything to suggest it's
there.

At the edge of the frame, on some hard edges (black/white) both blue and red
was being interpreted by the sensor and registered as purple when the green
sensors didn't get any info

- it's the same old bayer array issues that any digital camera will
experience (red/black, blue/black edge failure) which can and is corrected
by software but wasn't in the early 828's. It's simply a case of the
software masking for purple and interpolating in grey. Don't worry - all
digicams interpolate data into the shots, after all some sensors have only
got 25% of the sensor area covered with light sensors, where do you think
they get the 'image' from? The image data missing is interpolated *into*
the shot from the data the camera does actually see.

In theory you could set up a grid showing happy faces and sad faces
alternating along the bayer grid and take a photo at say distance a. and see
only happy faces, move the camera the proscribed distance in the other
direction and you'd see only sad faces (!) ..but I digress.

go for it - it's a giant killer in disguise and has an unmatched colour
fidelity given it has a 4 point sampling method across the spectrum and
every other camera only samples 3 points. Design is brilliant too

while you're there type in Canon fringing, then Nikon fringing ;-)

The Nikon 8080 or the Konica Minolta A2 are far better cameras. The
Sony isn't bad but it certainly isn't the best.
