    Well folks-

    More than a few people have been looking for a simple inexpensive flash solution for our favorite Olympus DSLR cameras. Tonight I attached the DigiSlave 3000 to the E-420 camera. Deploying the E-420's built-in flash I was ready.

    The E-420's built-in flash would act as an "optical trigger" for the DigiSlave 3000 Slave Flash. The results speak for themselves, just look at the attached photo!. So now you have the potential of an external flash costing just $(US) 100.00, that really works well. However, with the price of the FL-36 falling rapidly, the DigiSlave only has a very limited application to Olympus DSLR cameras. A Slave Flash is much more adapted to point and shoot cameras that are not equipped with built in hotshoes.

    Happy Holidays!

    Sunday Experiments

    Today (12/28/08) I decided to do some tests on the two ZD 40-150mm lenses that I owned. For clarity sake the one I call the "short" ZD 40-150mm is actually the newer version of the ZD 40-150mm lens that is now manufactured in China.

    All of the photos were taken with my E-420 and the FL-36 flash with diffusser. Auto ISO was used to be sure all the parameters would be the same. The first photo was taken with the new, short ZD 40-150mm version of the lens that is manufactured in China.

    Sunday Experiments Part 2

    OK, here is the second photo, the camera, the flash, and the settings are all the same, all I did was change the lens. The short ZD 40-150mm lens made in China came off, and the older, longer, ZD 40-150mm lens made in Japan went on to the E-420.

    Here is what that lens produced. I believe that you can see a qualitative difference between the two photos. The old lens is better! What do you think?

    Sunday Experiments Part 3

    To be completely fair, I also did comparison shots at ISO 1600, with the FL-36 dismounted from the E-420 camera. This is the short ZD 40-150mm lens made in China

    Sunday Experiments Part 4

    OK, this is the last one. This was taken using the ISO 1600 and the older ZD 40-150mm lens that was made in Japan.

    Missing Photo

    OOps! here is the missing photo. Again I believe you can see a photo quality difference. What do you think?

    There is definately a difference Sarah I agree but are you sure it's all down to the lens. The two shots with your newer lens look terrible & just seem out of focus to me. Surely that lens can't be that bad.

    Sarah I was so dissapointed with the lens performance on that first shot of yours I thought I'd check the exif info and there seem to be several differences between the shots. This is what I think you used.
    New lens (with flash)
    f5.1, focal length 106mm, shutter 1/20s, iso 1600, exp comp +0.3.
    New lens (without flash)
    f5.1, focal length 106mm, shutter 1/30s, iso 1600, exp comp -0.3.
    Old lens (with flash)
    f4.3, focal length 123mm, shutter 1/180s, iso 400, exp comp +0.3.
    Old lens (without flash)
    f4.2, focal length 118mm, shutter 1/40s, iso 1600, exp comp 0.0.

    I didn't get any flash info at all but that may be just the way I read the exif although I don't think your flash has fired properly on the first shot otherwise why would it pick a shutter speed of 1/20s and iso 1600?
    The differences between old & new in the without flash shots seems more reasonable to attribute to the lens althogh still worse than I would have liked to see as I have one of the new versions myself .

    Product shot

    Greetings,

    This is a quick and dirty product shot for the classifieds on another forum

    28" light tent, light grey backdrop, 10" reflectors with 45w CF bulbs on each side and a 26w CF from above.

    Talk about a short memory, sigh...

    I first set up with just the backdrop and of course the lights were reflected in the lens, duh...
