||I have modified the mounts of a couple of my fathers old Konica Hexanon lenses from the late 70s to fit my Olympus E-520.
The physical adaption works great, but due to the small viewfinder of the E-520, it is really hard to focus the lens
without using the Live-view display with magnification. This sadly makes the lens almost unusable handheld...
Now for the good part - the Dandelion chip!
I bought two of these chips and received them (in Sweden) after just 7 days. The mounting guide was pretty
straightforward, but the chip and the chip support are really tiny. You need a steady hand and some patience when you glue them together. As I don't use an adapter to mount my lenses to the camera, I can't really comment on how the mounting guide(the white plastic part) works for an adapter, but it worked well for my modified Konica mount.
Programming the chip is easy if you follow the instructions carefully. If you are going to input text, I recommend
you to write out the translated input data before you program the chip. You will know what I mean when you have tried it...
For my Konica Hexanon 50mm f1.7 I set the following data:
Aperture: 2.0 (thats the biggest usable aperture with the E-520's small sensor)
Name: Konica 50mm (Only 12 characters can be used in the Olympus)
Focus adjust: 13 (I compared the live-view focus with the focus indicated by the chip and noticed that the chip back focused a little)
All in all I am really pleased with the Dandelion chip and the Tago tech shopping experience.
