Leica have released a new 80 page guide to their range of M and -R lenses. There’s a downloadable PDF file that gives you a taste of what’s in the guide, with the full printed version costing $10 from local camera dealers.

“More than 80 pages will give you sufficient information on the actual Leica M and -R lenses. The Leica philosophy on the optical design, the manufacturing of the lenses and their construction as well as the universal use are other subjects in this book. Besides practical performance proofs of the different lenses you will find a photographical essay on the manufacturing of the lenses in the Leica shop by the fine-art Leica photographer Ralph Gibson. The extensive designed brochure is available at your Leica photo dealer for a nominal charge of $10.”
