Some time ago I put forward a User Report on the 50mm Jupiter 3 f/1.5 which caught the attention of Brian Sweeney. For those that are not familiar with Brian’s name he is an authority on the Jupiter 3 and over the years he has helped many people get the best from this lens in terms of performance.
It was suggested that my website was the perfect place to host the plethora of technical information that existed and I was obviously happy to agree to this. To this end Brian generously set about collating and updating the documentation you’ll find here. So, thanks to Brian’s generosity and a little later than I had planned I am able to advise that the 50mm Jupiter 3 f/1.5 User Report has now been updated with the following instructions –
- Jupiter 3 – Exploded & Labeled
- Shimming Instructions
- Focal Length Adjustment Instructions
- Clean & Lube Instructions
- Contax to Leica Conversion
