I have finished the first step (getting the gear in one place...) of doing a little comparison between a few cameras, all sold about the same time. I am curious to see how much difference can be seen just looking at the photos. I am sure it's been done but I just thought it would be an interesting exercise.
Here's what I'm thinking of comparing:
- 35mm Argus Sandmar f/4.5
- 50mm Argus Cintar f/3.5
- 100mm Argus Tele-Sandmar f/4.5
- Argus Optical Viewfinder (Clip-On)
- 35mm Lithagon f/4.5
- 50mm Argus Cintar f/2.8
- 100mm Lithagon f/4.5
- Geiss C4 Viewfinder
- 35mm Summaron f/2.8
- 50mm Summarit f/1.5
- 90mm Elmar f/4.0
- Nippon-Kogaku Multi-Focal variable finder (or integrated frame outlines)
And as further insult to injury, I might make an (unfair?) comparison with (gasp):
- Super-Multi-Coated Takumar 35mm f/3.5
- Super-Multi-Coated Takumar 55mm f/2.0
- Super-Multi-Coated Takumar 105mm f/2.8
My thinking is that these are comparable focal-length lenses being aimed with their companion viewfinders on rangefinder equipped, 35mm bodies. Naturally, all shots would be done with all variables matched (f-stop, indicated shutter speed, camera angle to subject, use of hoods, cable release, etc.) This is not a test to count molecules of grain, lines-per-inch, etc., just a comparison of practical results and perhaps some observations about ease of use...
Don't expect to see the results soon. Life is full and shooting will take a while.
