While waiting my EX.. one more question..

Will generic close-up lens/filter work with EX1? In other words can I focus closer with one?

And btw what is the minimum focusing distance for EX1 as it is? Haven't been able to find that by googling.

and this one is also still mystery to me

The EX1 has a macro facility.
How close can it focus ? I went on a demo and saw the demo guy switch the macro function on and he held a memory card almost touching the lense hood,i'm talking 20mm from the lense hood and the cam focused on it,i was watching on a monitor and i could clearly see the writing on the card and the metallic fleck on the paint on the sxs card.
Is this close enough ?

yes the cam does focus very close....

although a close-up filter will allow you to have the camera a little farther away.... and or allow the camera to focus closer while zoomed in more.

I recommend a quality close-up lens that is multi-coated to help minimize internal reflections. Be aware that most will cause CA at the edges.

Tuomas,

Schneider Optics manufactures an 86mm Achromatic Diopter which enables significantly closer focus than your camera is capable of. These diopters are unlike other diopters because they feature two elements instead of one so that your image will be free of soft edges and chromatic abberations. You simply use a step ring to go from 86mm to 77mm. To calculate the minimum focus distance of a diopter at infinity; divide the power of the diopter by 40. Better yet, send me an email and I will send you an Excel chart that calculates focus distance based on your cameras minumum focus distance. Diopters linked below.

Achromats by definition are not free from chromatic aberations as they are only corrected for 2 wavelengths of light, Doublet lenses are certainly an improvement over simple single element lenses but most achomatic lenses show significant purple or violet fringes. Only Apochromatic lenses which are normally triplet lenses using exotic ED glass are truly free from chromatic aberation.

Does anyone know if this would work with the EX1?

Ah, no its way too small I see now.

While this is correct lens theory, I have yet to experience chormatic abberations with our achromats. Either way, you are correct in that they reduce but do not eliminate the incidence of this problem.
