Rolleicord V with a 75mm F:3.5 Schneider Kreuznach Xenar single coated lens, the better of my two units
NOTE: Flickr makes a .jpg of uploaded files. The Jpeg process reduces actuance. The original scan has more detail than the .jpg file and in turn the original scan has less detail than is on the film. The film probably has 4 to 9 times (2 squared to 3 squared) the detail as you can see if made with a cracker jack lens and top rated film.
1. The bus was about 185 meters away from the camera.
2. The film does not have the reddish/maroon look that you see here. Scanning with the Kodachrome film type selection instead of the proper Color Positive selection miscolored the scan, my fault
Photos taken in this set were to test various stock lenses on some of my cameras. I started out with old 120/620 folders then added some modern 120 filmed examples. There will also be a few 35mm and 127 tests. You will need to open these up to their original size to see how good or bad the lens is. Also please see the type of scanner that was used because not all the scanners were able to scan at the same resolution.
Unless specifically noted, over time I used several films for these lens tests. Various Kodak and Fuji 100 speed reversal films and Fuji Velvia 50 speed were used. The difference in sharpness of the film was far less than the difference in the lenses.
Please take into consideration that when Flickr jpegs the uploaded tiff file some of the detail is lost so the original is sharper than what you can see.

The Pictures...
These recently uploaded pictures have no artistic value. They were just uploaded to be representative of color picture recording during about 85+ years that I was able to take color pictures, mostly slides at first. Unlike in today’s digital world it took time, money and effort to make a color slide. We took fewer pictures back then, trying to stretch resources, but some sere still frivolous.
I'm 97 (2016). I'm about at the end of my ability to continue posting. The ratio of today’s digital pictures that are kept for any length of time and/or printed is much less than the film photos taken in days past. History will be lost. Meanwhile you get to be bored by some old Kodachromes, Anscochromes, a Dufaycolor and perhaps an old black & white or so.

The first picture I remember taking was in the mid-1920s when my mother's sailor boyfriend brought an overseas camera to San Pedro.
The Camera: Rolleicord V, ca. 1954
I used a used but good condition Rolleicord V ca 1954. It has a single coated Schneider Kreuznach 75mm F:3.5 Xenar four element lens. I bought a second one so I could make medium format 3D (Stereo) slides. The two like cameras are less than 100 serial numbers apart but the second lens is not up to the quality of this one. Using the USAF1951 chart this lens gives over 60 lp/mm at F: 11.
The film: Fuji Provia 100 or Kodak E100:
This was shot on Provia 100 or Kodak E100 in 120 size. To scan with a 35mm dedicated film scanner I first used a Mamiya Super Slide punch. The film center was then mounted in 127 sized slide mounts which have the same external dimensions as 35mm slides. The surrounding mount has thinner sides than 35mm. This does give a 35mm scanner a chance to scan all film instead of having some mount blocking and reducing the amount of picture taken.
The Scanner, Minolta 5400 II:
The Minolta 5400 was advertised at 5400 PPI and actually gave out not only a scan of that size but also of that resolution. Testing was done using a 1951USAF glass microscope resolution bought from Edmond Scientific. When scanning a chart at maximum resolution one has to be concerned with registration between the lines on the chart and the pixel placement of the sensor. Exact registration is a hit and miss, re-trial exercise. With film the scanned bits of silver and dye clumps are randomly scattered without the need to have perfect alignment.
