Taken with an old Canon 135mm rangefinder lens on my M8.
Clicking on the thumbnail below, then on the "Full Size" link (or the image itself) on the ImageShack page will take you to a full size version (approx. 2500 x 3700 pixels) of this photo so you see the quality (sorry about the squares and lines - my agency would be unhappy if I released pristine images into the wild!).
I say full size - I have cropped it a little, but haven't reduced the size.
As an aside, you may be interested in why I use this Canon lens and not a more modern Leica one. The reason is that the latter will give a higher contrast image but not one appreciably sharper. But I prefer lenses from the 60s-80s with digital, as I feel that the modern taste for high contrast does not suit digital, leading to loss of detail in shadows and highlights (the situation is much improved with modern cameras, but it's still there). With an older lens, I can always create a more contrasty look if I prefer, but it's harder to reduce contrast as information required for better tonality may be missing in light and dark areas in photos taken with a modern high-contrast lens.
PS: I place imaginary framelines between the 90mm lines and the focusing patch. Oner of those cheap-ish eBay viewfinder magnifiers helps, as does chimping. Despite the long focal length, focusing seems to be as accurate as with a 90mm lens (i.e. not problematic, though care is needed).
