I am planning to buy an MP-E 65mm in February, and I'm not sure if it's worth the additional $40 for the hood. It seems very worth it in theory, because when you work at extremely close distances at the higher magnifications, you are almost firing your flash directly across the lens. Doing this with other lenses causes a reduction in contrast and can create flares and other unwanted artifacts.
Also, does anyone use a clear filter with this lens? I am not nearly as convinced of the usefulness of this item for this particular lens, but I would be interested in hearing the opinion of anyone who has actually tried one with positive or negative results.
