Mark, I believe it can make sense. Don't forget that most DLSR's don't go in 
pro, or semi-pro, or would-be pro hands. The very most of them will end up 
in amateur hands of any level and skill, where a better in-camera JPEG 
conversion (or a better lens, or a faster AF, or a wider exposure latitude, 
or a better tuned meter, or a better whatever) still makes a lot of sense.
I know folks who bought the Ds and even don't own a computer, nor they want 
to buy one just for getting the damn prints.
Yes, those folks will hardly print formats larger than A4, but knowing that 
they can go well beyond that size won't hurt them and won't prevent them 
from buying a camera with a better reputation.
At the end of the day, if it's better, it's better (even if you don't truly 
need it).

One needs to know whether the test lenses were of equivalent quality, and 
how the image files were post processed before one can make a fair 
assessment of whether or not the resolving power of the camera.
I was in Lloydminster yesterday looking at purchasing a Gretag Netprinter 
with a friend.
I gave the vendor an in camera JPEG to run as a test file. They run Nikons 
and Canons in their studio, and have in camera processing set on the high 
side of neutral, and run the files through Noise Ninja to clean up the 
resulting artifacts.
I gave them a file with the camera set to my default settings, which is 
minimum contrast, saturation and sharpening, which was shot with my 31mm LTD 
lens.
The guy took the file, and ran it through his post processing routine, and 
made a spectacularly soft print.
While they were making snide comments about garbage Pentax equipment, I was 
out reshooting the file with the camera set to it's highest settings for 
sharpness, contrast and saturation.

The resulting print made their girlycam files look pretty junior.
I thought the resulting image looked overdone, but I also didn't have a lot 
of use for what they were churning out.

The Netprinter turned out to be a dog, BTW.

Re: Pop Photo D Shoot-out

2006-02-13 Thread Adam Maas
Effective resolution is pretty much identical between the cameras (The 
5D even uses the same sensor as the Pentax and the D50 uses a variant of 
that sensor). The big advantages of the other cameras are in Write 
Speed, buffer size and AF speed. The DS2 wins on ergonomics, size and 
viewfinder. The 5D is also an oddball (good viewfinder, Anti-Shake, but 
otherwise fairly similar in performance to the others).


Is PopPhoto still claiming that the XT does 3.2fps?

PopPhoto's DSLR tests are not well done, they've repeatedly claimed 
ludicrous or simply inaccurate results, and seem to pick winners based 
merely on advertising revenue. I stopped reading them a while back 
because their reviews were so divorced from reality (the Rebel XT review 
was the breaking point, really badly done)

Well, I agree that Pentax could use a new 8-10MP body in their
lineup, but I found their analysis of the DS2 and its competitors
somewhat superficial.  They didn't seem to note the reasons so many
find it attractive - the excellent (for a DSLR) viewfinder, the light
but solid construction, and the excellent ergonomics.  Instead, they
seemed to zero in on some of the gimmicky features that it lacks.

These quickie comparos always seem to fall short of getting to the
heart of the matter.  I suspect that the rankings are driven more by
marketplace popularity and advertising revenues than anything
else...  They did have a favorable review of the DA14 in the same
issue, though.

Careful, I'm about to blaspheme! I warn that even though I'm not
faulting the DS2, but just stating my reaction to ergonomic, structural
and operational convenience points.
To me, the image is everything. If I need fiddle with menu options and
become irritated at some irrational design blunder, I could easily
overlook it if the image were worth it. Admittedly, said determination
is to a large degree subjective with each user having their own unique
set of standards.
It surprised me somewhat to read a critical admonition of an

Surely true. Although by and large the differences in in-camera JPEG  
rendering are more a matter of what trade-offs the manufacturer made  
with respect to their expected audience.


Pentax designed the in-camera JPEG rendering defaults of the DS et al  
to produce very high quality 4x6 prints straight out of the camera,  
not to be the ultimate settings for image post-processing and large  
size prints. Canon's defaults on the 10D and 20D JPEGs are much more  
attuned to the notion of editing, leaving much more overhead for  
sharpening, and differ from the defaults on the 300D and 350XT which  
are more like the Pentax.


For all of these cameras, you modify the JPEG rendering engine's  
settings to meet the needs you have if you want to produce better  
files for editing, or you go to RAW format and do the rendering  
yourself. It's no surprise that Pentax supplied RAW conversion  
software uses algorithms similar to what the camera does, just like  
Canon's RAW conversion software uses algorithms similar to what their  
cameras do.


*ANY* JPEG rendering from [EMAIL PROTECTED] RAW data is tossing 40-60% of  
the data away. It's in the nature of the conversion process, which  
does gamma correction, chroma interpolation, and reduction to  
[EMAIL PROTECTED] RGB color space, then JPEG compression. What parameters  
you set in the algorithms determine the quality of the final output,  
and have to be optimized for specific purposes.
