Where's my Esper?
Fuji GSW690III Resolving Power

The vignetting is completely artificial, as is our owl.

So what exactly happens when you take the world's sharpest 6x9 lens (the 65mm f/5.6 Fujinon on the Fuji GSW690III) and combine it with one of the world's finest-grain black-and-white films?  Looks a lot like pictures taken with a laser. 

The camera.  A stock GSW690III, shot at 1/60 and f/16, with a G (orange) filter.

The film.  Current T-Max 100 in 120 size.  Developed in T-Max developer (so you do pick up a little film speed but give up some grain).

The scans.  Done with Vuescan on a Nikon LS-8000 with a glassless (yes, the hated glassless) carrier (see my technique for film flattening here). 

How big are these enlargements?  If your screen is 96dpi, the sections below (scanned at 4,000 dpi - file size 228mb in 16-bit) are the equivalent of a 42x enlargement.

Would a drum scan do even better? Yes.

Would a glass carrier?  Potentially flatter film but less resolving power.

A condenser enlarger?  How would you feel about a 120" wide image?

The upshot. It is easy to build a lens that returns this kind of resolution in a 24x36mm field.  It is not easy to do so across a 6x9cm field.  Fuji has done an incredible job with this camera.  Why do people even bother collecting the older ones?!

We're not quite at reading license plates, but close.

Just picking up the seamlines.

The reflection in the window is the cornice of the picture on the left side of the frame.

This bridge is about 2 miles from the camera.

Fire escape.

Can you read the name of the newscaster?  Probably not fair, since this train is moving and the shot was taken at 1/60 sec.


I would like some balloons.  A lot of balloons.

You can really see where Bob cheaped out on the Z-track.
