I would like to point out the few comments placing sharpness (acutance), and fine grain on opposite sides of the scale. I cannot overemphaize how many comments I get on my work shot at 400 and 800 on Fuji's Neopan in FX-2. I use Nikons with prime Nikkors only, and print the resulting negs with a 50/4 EL-Nikkor. If you can get past the stupid (sorry- that's just my opinion) GRAIN Issue, You just might surprise yourself.(posted 8392 days ago)I feel however, that good lens choice can make all the difference in the world- and there can be holes in otherwise good lenses- the 50/1.4 AI-nikkor is great from f/5.6 to 16, but is scary from 1.4 to 4. The 180/2.8 AF-N Nikkor is AWESOME wide open to f/16, but avoid 22 and 32, the depth of field isn't worth it. The 105/2.5 is great regardless of aperture, but check your depth of field for optimal "Bokeh".
I hope that you're not working for someone other than yourself, or if you have clients, shoot some personal test stuff with different variables, specifically developers and EI's. If you think it looks good enough, shoot some more and show clients. You don't know how they'll react! Like I mentioned earlier, My EI400 and 800 shots are unanimously sharp, and that's all I care about.
And when I load rolls of Tmax 100 in the same soup- Oh My Goodness!!!
In my opinion, the pursuit of high spped and fine grain is the decline of image quality. Fine grain is done best at EI25-100. Those looking for Fine Grain with High Speed are chasing pot of gold at the end of rainbows- they'll never seem to quite get there.
