Download a 30 day trial of Bibble or Breezebrowser. Both very easy to use.

Trying to use rawshooter essentials... installing the new version.

For RSE, make sure to set sharpness and detail extraction sliders ALL THE WAY to the left. Otherwise, it sharpens. (Actually, it still sharpens a bit anyway, according to the converter comparison I read)

I just did one at 0 sharpening and unchecked the processing sharpen checkbox and i did another at -50 sharpening and both looked exactly the same to my eyes unless I messed up somewhere.

let me do a quick test.

also if I send you the raw file, could you process it in your converter for comparison?

Note that RSe doesn't show you sharpening on screen except at 100% and above magnification. Note the Detail Extraction slider should be at -50. Also, make sure you are looking at (and posting) at 100%, you have to use a second program to do the crop to 640x480 before posting, since RSE doesn't offer cropping during processing like Bibble does.

Here's a review of RAW processors where they say that RSe is sharpening even at -50. It's an interesting read, especially now that you've started doing some raw:

Raw Converters Review

Note also I expect most the 100% crops to be "soft". That's just a fact of life. But seeing how lenses perform this way will help us understand what the good lenses captures are like, "straight from the sensor"

-50, 0, +15 sharpening. I know they don't quite line up perfectly. Also if you want to process the raw file for me if i'm doing it wrong... I can send it to you via e-mail. 6.88mb.

image updated with actual sharping.

Unfortunately, Pentax' built-in RAW program doesn't allow cropping and saving of RAW images.. so I had to convert to 16bit TIFF.. but then was informed that The GIMP doesn't handle 16bit TIFF images.. so blah..

It's too late at night to get a decent daylight shot right now anyway, maybe tomorrow.

Here's my first submission. I took a picture of a poster on the wall (which is poster framed, and has that cheap plastic in front.)

Sigma 18-125,
F-stop: 8.0
ISO speed: 200
Focal length: 125.0000
Flash: Not fired
100% Crop, RAW, unsharpened, processed in Bibble:

Same crop, showing how it looks with some sharpening applied in Bibble, amount 124 sensitivity 3:

PostNote: I just realized I didn't color balance, so the colors are off!

Ok, here's another lens:

Here's my 70-200/F4L for reference:

Unsharpened image at 200mm (hmmm, I didn't shoot an F8 like the others)

RAW file 100% Crop NOT Sharpened:

RAW file 100% Crop Sharpened in bibble:

While I didn't shoot F8, note that of the three tests I've posted so far, the Sigma is the sharpest lens IMHO.

Please do not post non complying photos, it dilutes the value of this thread in seeing how these lenses fare against each other with as much "equal" as possible in this informal test.

It is a RAW capture. ??

Ok, sorry, I thought not, because as far as I know, RAW captures aren't named IMG_ by Canon firmware. JPG images are. But perhaps you name it that, or your camera/software behaves differently.

My RAW files are named CRW_0000.CRW
My JPG captured files are named IMG_0000.JPG

Your file started with IMG_. Out of curiosity, what are you converting this to JPEG with? And how is it ending up IMG_?

EOS 20D Raw files are suffixed 'IMG_XXXXX.CR2'.

It's just a JPEG for DPC upload (via Save for Web' in PS).
