Will you help me ?
I can't have my eyes everywhere and if you are aware of any information
specific to the Olympus E420 which isn't yet available here, or if
you'd like to leave your own user report, you can send it to me here.

- Some of these packages are free, some are not.
- I have tried out a number of these packages and in my opinion the
Adobe Photoshop one delivers the best performance in terms of image
quality, user interface and processing speed (with some decoders when
you make a change to the parameters you have to wait for a while until
you see the change in the preview window).
- If you use Photoshop you will need CS3 or later versions, because
CS2 (or earlier versions) cannot import the camera raw file filters
needed for the Olympus E420 RAWs.
- Olympus has released a codec
for Windows Vista.
The codec is a piece of software running under Windows Vista with which
Vista can import and display RAW images of all Olympus DSLRs.
- Another good RAW converter is Olympus
- Even Irfanview can
decode E420 RAW files, thanks to the dcraw code.
- The E420 has a dual slot for CompactFlash card (Type I and II),
Microdrive and xD picture cards.
- There is no reason to use xD cards (unless you want to use the
inbuilt panorama function), since CF
cards are cheaper and usually faster.
- Firmware updates released so far (can be downloaded here):
- Version 1.1, 30.09.2008
- Improved brightness level of optical viewfinder AF target

- To remove chromatic aberrations you can process the RAW image
with the Adobe Photohop RAW plugin.
- To remove chromatic aberrations with
an image editor (desaturation of the magentas):
- It is very simple to remove chromatic
aberrations from an image. Simply use a photo editor and set the
level of magenta (also green where this makes sense) to the minimum. In
some images you might have to set the saturation level of red to the
It might also make sense to limit the processing to the affected area
select the affected image area and only process that).
- The ME-1
eyecup magnifier enlarges the view by 20%. The eyecup incorporates
two lenses and measures 40 x 30 x 12mm.
- The FP-1 Power Flash grip is designed for use with the FL-50
high-voltage pack and can be used in combination with the flash unit's
built-in power supply to provide fast flash charging for an extended
number of shots. The head is can be rotated by 180° for increased

the Olympus E420 with a computer
- Olympus is currently not offering an underwater case specific to
the E-420, but the PT-E03
underwater housing for the E400 and E410 might fit. Policarbonate,
waterproof up to
40m, takes the FL-36 TTLflash with the PFL-01 & PFL-E01
flash housing. Five interchangeable lens ports allow the optional
use of the Olympus 14-45mm, 14-42mm, 11-22mm or 14-54mm, 7-14mm, 8mm
Fisheye and the 35mm as well as the 50mm Macro lens.
- Olympus also offer several
lens ports needed to use the Zuiko lenses underwater. There are
lens ports for the 14-45, 14-54, 50mm, 7-14, 14-42 and for the E-14
teleconverter as well as other accessories needed when using the camera

to images which lost it due to processing with a software package which
doesn't support EXIF. Quoting from his site:
"Exifer is a nearly free software

with which you can manage the metadata (EXIF/IPTC) of pictures taken by
digital cameras. Because many image processing software destroys this
when saving such files, the idea was to create a backup of the metadata
before editing it in any software, and then, after that to restore it
into the processed file. With Exifer you can do this very easily. "

(which I have been using for years now): not free but an excellent
piece of software.
