when you buy them new, you can get crazy offsets
if you look on yahoo japan you might find some like that
but obviously the choice and range is a lot more limited when buying used
lol
it was a joke
but i guess if you used a grey card to set the WB it wouldn't take so long...
but yeah, i know what you mean about working with warm lights
the ones i use at work make it so much easier to get accurate colours
