Leica Summilux-R 50mm f/1.4 (via adapter on Canon EOS) Review / Test Report
Lens Reviews - Canon EOS (APS-C)

Special thanks to Jonas B. for providing this lens!

Introduction

Every once in a while it's fun to take a weirdo for a test drive. Such a combination is surely a Leica Summilux-R 50mm f/1.4 (E60) adapted to Canon EF mount used on the Canon EOS 350D (Digital RebelXT). Now what does that mean ? Naturally the Leica remains what it is - a manual focus lens - and using a conventional adapter there is no electronic coupling to the camera whatsoever so the camera does not even "know" that there's a lens attached to it. The viewfinder shows you an aperture of f/0.0 regardless of the effective aperture. If you stop down the lens (via its aperture ring) you do so immediately (thus the viewfinder image gets darker and the depth-of-field increases) - there is no automatic aperture available here which you would naturally have on a native Leica SLR/DSLR. Consequently you can only take advantage of the manual and aperture priority program modes. On the EOS 350D is was necessary to underexpose by about 1 f-stops in order to achieve a valid metering - this may vary dependent on the specific base DSLR. The focus indicator in the viewfinder does NOT work. However, this specific aspect is only partly true because by now you can also buy electronic adapters which fake a conventional EOS compatible lens thus activating the focus indicator of the camera.

As you can see above the lens has seen some abuse over the years. Nonetheless it remains a rock solid lens made of superb materials with exceptionally tight tolerances. The focus ring operates very smooth and very well damped - no native EOS lens offers such qualities here. You can change the aperture in half-stops from f/1.4 down to f/16. Selecting a certain f-stops is very precise but doing so produces a fairly loud "click". The lens extends a little when focusing towards close focus distances. Leica has implemented a small built-in lens hood (not shown below).
