Consider your search for the perfect slow speed black and white film over. I've shot a vast number of b&w films over the years, and the one I consistently come back to over similar speed emulsions from Kodak and Ilford is Fuji's Neopan 100 Acros.
The film features extremely fine grain even in the 35mm size, which means that you'll have to make some pretty large enlargements or scan at a high spi settings to even notice the grain. Another great quality of the film is its solid edge contrast even with moderate sharpness developers like Kodak's Xtol. Please note that Edge contrast plays a significant role in the perceived sharpness of an image, and can be influenced by the film and the developer you use.
The film also features excellent reciprocity characteristics. No exposure time adjustments are necessary for exposures under 2 minutes, and only a half stop of extra time is required for exposures up to 16 minutes long without any development time adjustments necessary. All this makes this film an excellent emulsion for night and long exposure photography.
Dynamic range is also one of the key strengths of this film, and the range of tones and detail retained in highlights is spectacular. You can easily meter for a subject in the shade, and expect for the details of areas in direct sunlight to be captured.
In terms of developers, I would highly recommend Kodak Xtol for this film for the fine grain and good acuity. Diafine also works very well if you wish to shoot the film at EI 200. Also note that the film does not exhaust your fixer as quickly as the TMAX line of films from Kodak.
Great price for this film here on Amazon. I normally buy my film from freestyle photo supply but they were out. I've used all the major brand names, Ilford Deltas / FP4 HP5 Pan F 50, Kodak tmax and tri-X(my least favorite) Efke, Rollei, Arista and various other black and white film. I think the only other film that even comes close to the sharpness of Acros is ilford FP4. Hardly ever any fogging if processed correctly. Even the 35mm size negatives are amazing quality. Acros Neopan is by far the best film I've used. I develop it myself and used various kinds of developer though I will let you in on a little secret: Use Kodak TMAX DEVELOPER!! uber fine grain, strikingly sharp edges and a sweet contrast you won't find with other films. How is Acros cheaper than Ilford film? I don't know. I scan my negatives with a Canoscan 9000f so I know with certainty how fine the grain is.
As a long-time devotee of Kodak's Plus-X and Tri-X emulsions, I spent most of my (very amateur) photography career avoiding tabular grain films. I'd tried T-Max (Kodak again) and Delta Professional (Ilford) in both 100 and 400 speeds, but with limited success--I was never able to hit the sweet spot between acutance and contrast. Fuji's Neopan Acros 100 changed all of that. The 120 film delivers consistently beautiful negatives, razor-sharp and rendering a complete range of tones, especially when I pull the processing a bit (I usually shoot it at 80, then knock 10-20% off of the development times, depending on conditions). If you're new to traditional or to black-and-white photography, or if you're just looking for an amazing film at a great price, I can't think of a better place to start than with a pack of Acros 100.
I use this film in a mamiya rb67 pro... which is the original 67. I find that this film delivers great density, and tonal range. I'd like to mention that it has a super fine grain... which, if developed correctly can also give you a grainy look if that's what you're looking for (akin to tri-x) or if you develop say d79 1:1... it will give you fine detail like (tmax-although t max is a t grain film)... Fuji did a great job with this film.I recommend it...
Acros is a great film for detailed images, especially when paired with a developer like XTOL. However, we careful to meter for the highlights which are very easy to blow out. If you don't trust yourself, use Ilford FP4+ which is more forgiving.
