I don't use a divisor, and I've never encountered a moire pattern. I have
tried using a divisor, but I eventually learned that it accomplished
nothing. I've made close to a thousand hi-res prints. I'm sure you've made
more Aaron, but have you worked extensively without a divisor? In order to
achieve the divisor at a given print size, you have to resample the image.
That is perhaps the most damaging thing one can do. The printer resolution
numbers don't correspond in any way to the ppi counts of digital files.
Congratulations on the 75/2.8 purchase. I anxiously await your
appraisal. I picked up a late model 105/2.4 off ebay to add to my 150/2.8.
I think the 55/4 is my next buy, but I'd also like the 75. KEH doesn't
have it yet, or at least they don't list it on their website. Do you want
to whisper how much you paid for it? :-)
