Here's some info on the ADOX CMS 20 film... While the 800 l /mm resolution sounds a bit optimistic, the sample photos sure look impressive: http://www.adox.de …Films/ADOX_CMS_​Films.html (external link)

"No other film is sharper, no other film is more finegrained, no other film resolves more lines per mm (up to 800 l /mm)."

Zeiss recently tested their 2,8/25 Biogon ZM at 400 l /mm: http://www.zeiss.com …3ED0C97A7C12571​1C006FC2C2 (external link)

Another Zeiss lens test shows similarly high resolution: http://www.zeiss.com …46D590A3FC12571​1C00693B3F (external link)

I've heard some people who know this area much better than I really dispute the 800 lp/mm claims of both Adox and Gigabit. Not sure what that's based on. But it hardly matters -- I have a lot of Tech Pan, and high res or not, FP4+ sure looks a lot better than it when you're shooting planet earth and not resolution targets.

I would have to agree, 800 lp/mm is a bit optimistic and maybe to a degree "theoretical." But it's definitely pretty high. There's also Bluefire Police film, which I think is similar to these others. ADOX briefly went under the name of Efke (now it's back to ADOX). Tech Pan was awesome; I really miss it.

I've never shot a chart, rulers or batteries in my life. Boring.  :p

There are others too. You can get orthocromatic lith film, which is extraordinarily high resolution and high contrast. It's only sensitive to blue light, of course, so your shots will look a lot like the Timothy O'Sullivan landscapes from the 1860s, but that's not a bad thing. Some people will actually use microfilm and cut it for 4x5 film holders.

Developing Tech Pan in Technidol has created unusably high contrast for me. I've done some semi-stand development in xtol, though, and it tames it. Its resolution won't be so high, but the grain is still basically negligible.

Back in the day I had a lot of fun with Tech Pan and Lith Film, especially the latter. Exposed a 4x5 or 8x10 sheet in the enlarger, then contact printed that (making a postive and negative) and offsetting, exposing that onto paper, etc. Time consuming, but it made for some really neat "ink drawing" photos.

I just picked up five rolls of Tri-X (my standard these days), two rolls of Ilford Pan-F+, two rolls of Fuji Velvia 50 (naturally), and two I've been eager to try... A roll of Rollei "Advanced Technical Pan" (you guessed it, a Tech Pan replacement) complete with enough developer for the roll (sample kit) and of course - five rolls of the ADOX CMS 20 film mentioned above and its matching devloper, enough for five rolls. 15 rolls of film to shoot, w00t.

I usually use Xtol myself these days, typically 1:1. I used to use Acufine, Diafine, HC-110, Technidol, Microdol-X... Good stuff.

The other day I went out with a specific goal in mind. I grabbed a roll of Tri-X and purposely pushed it to 1600 because I wanted plenty of grain, knowing I'd also develop it with Xtol 1:1. I also tossed on my dark red filter, knowing it would make skies and green vegetation nearly black - and offer some serious contrast. I also wanted a deep DoF to provide plenty of contrast in the details. I'd say the experiment was a complete success... Click for larger/info:

There's more on page 5/6 of that exhibition (external link).

I wanted to try a softer look and used Ilford XP2 with a red-orange filter - definitely less grain and less contrast... They can be found in the same exhibition following the Tri-X shots above.
