Focal length

If by "focal length" you mean "zoom setting" (and not f-stop) the answer is no. I had the same question, especially now that I'm looking into a telephoto extender (mainly so I can know when vignetting starts).

There is a way, but you would have to a) Operate your camera via a laptop computer with the appropiate software, b) estimate the FL via the LCD screen. The range is 35mm to 105mm (35mm equivalent). By using a transparent grid, Ronchi ruling, or reticle (available at places like Edmund Scientific), over the LCD, one should be able to interpolate FL from the image size differences on the LCD. Using the manual focus step mode will facilitate the matter. I happen to own a C2000Z, which does not have the manual options like the C2020. If I did have a C2020, I would be in manual focus 99% of the time!

Eduardo,
Here is a method you could try. Assuming that you can go to a camera shop and "try before you buy", you could take some test shots and then come home and use software (such as Thumber and PIE) that gives you full EXIF info. All you would need to remember is the teleconverter/telephoto extender's magnification ratio and apply it to what you read from EXIF data.
As for showing focal lenths right on the camera, it would be a nice feature.

Well here is a good place for Olympus or some SMART programmer, to use an OLYMPUS brand smart media card. He could put a program in the card to display all the EXIF info onto the cameras display.
Now who's up to the challenge? HA HA

I'm not sure manual focus would always work best - it's not always easy to determine the sharpest setting, since you have the digitally zoomed picture on the LCD to guide you which is a bit jaggy and not perfectly sharp.

Try the LCD screen.

Ronnie,
It already has been done. Thumber and PIE give you all of the EXIF info. It is a shame that the CAMEDIA software does not. The only problem with this method is you don't know the focal length until after the shot. Granted this might work with Eduardo's problem but if you wanted to know the focal length before (or during) the shot, the camera itself does not display it. :-(

Johnny, I know that. I mean a Smart Media Program, like Olympus does with Panorama, Calendar, etc..(on the smart media card itself that the camera can execute)..... AND THEN display the EXIF info on the CAMERA'S MONITOR........... I know the camera displays some picture info, but not as much as what could be done. It's just a thought...........

Agreed. It would be nice if it was available during display while in the camera!Johnny, I know that. I mean a Smart Media Program, like Olympus does

I wonder if Olympus provides a programming reference for the Olympus brand smart media cards.......... I mean if it's a feature, it should be available to all to utilize. I am sure it would HELP sales rather than DECLINE sales to profide the information.
Anyone know????
