This is a comparison of various lenses in order to determine the sharpness, bokeh, Chromatic Abberations and contrast of the lens. This is not a scientific test but rather one which is basic with essentially the same shot taken on a tripod at aperture ranging from f1.4, f2, f2.8, f4, f5.6 and f8. Not all lenses were tested at f1.4 (for obvious reasons) and only some were tested at f8. I mainly concentrated on the normal usable range of f2.8 to f5.6.
Lenses range from Russian Helios 44M, 81N, Mir 1 and the Pentax Takumar Super & SMC 135mm, a cheap Access 70-210mm zoom, Olympus ZD 50mm (i think the focus may of been slightly off on this one), Rokinon 85mm, Nikon 50mm & 55mm and a Sigma 75-300mm.

This in some ways is a torture test because of the bright flower to the right which is bound to cause flare or chromatic aberrations, and the background is quite complex which will test the bokeh of the lens. Naturally this will favour longer focal lengths.

More will be added in time.
