K20D Review in "Amateur Photographer"

[Colin J]

I was considering buying a K20D because the low noise 14.6 MP sensor is 
particularly attractive.  However, the review in this week's "Amateur 
Photographer" was a little disappointing, particularly when referring to purple 
fringing.  

The review pointed out that a recent optical test of the 16-50mm f/2.8 DA lens 
showed no problem of chromatic aberration, so the reviewer concluded that the 
colour fringing must have come from the sensor.  

Any comments?  Why should I buy a DSLR with a colour fringing problem?

I have yet to see any purple fringing after 2500 K20D shots. But I  
don't shoot black branches against glowing white skies either. In  
fact, I've experienced more fringing with all of my other DSLRs. The  
*istD was the worst of them.

They are having QC problems with the lens you mentioned. It's pretty widely 
reported, I don't 
expect we'll be seeing any QC problems with it in a few months as new stock 
ships. Try to find a 
DSLR anwhere that doesn't dislpay some PF under certain conditions. They all do 
it, and it's 
easy to produce. Just take a picture of a subject so heavily backlit as to be 
unphotographable.

Since that's the opposite results others have reported I begin to doubt 
the veracity of any review. 

Look this is a situation , high contrast, that I would have expected to 
cause sensor bloom, and lots of it.



Made with the *ist-Ds and F 70-210mm.  I examined it closely and found 
almost none.  I think that reviewers are shooting images intended to 
produce it intentionally and don't stop until it appears.  They can then 
say "Ah-ha there it is."

There's your problem.  The K20D is targeted at enthusiasts and budding 
professionals.  Not amateur photographers.  Gees.
